1. INTRODUCTION

1.1 BACKGROUND

Cowaramup Bay is an iconic and unique part of the Cape to Cape landscape. It has a diverse range of biodiversity values and is on the edge of a township surrounded on four sides by National and Marine Parks. It is much loved and heavily used by locals and visitors alike. It has been identified by agencies and the community that a plan is required to ensure that recreational useage and visitation is managed such that the important and unique environmental, cultural and recreational values of the area are maintained. The plan has been initiated and funded by the Shire of Augusta Margaret River. 1.2 PURPOSE AND SCOPE OF THE PLAN

Litoria Ecoservices prepared the plan over a four month period between February and June 2019, following consultation with local residents, community and agency stakeholders and relevant Shire staff. This Cowaramup Bay Coastal Management Plan (the plan) provides detailed management strategies and actions for the area to guide on-ground works by both the Shire and community groups. The purpose of this management plan is to identify management recommendations to maintain and improve the key qualities of the foreshore site, namely:

• conservation values; • recreational and amenity values; and • social values.

The objectives are to: 1. maintain and enhance conservation values of the site; 2. foster community stewardship of and responsibility for the foreshore; and 3. facilitate sustainable recreation.

Key elements of the development of the plan involved: • an assessment of the current physical and ecological state of the site including native

vegetation, weed burden, dune stability, pedestrian and vehicle access and recreational usage;

• community consultation including input from local residents, community and agency stakeholders; and

• development of detailed, prioritised management recommendations for improving and preserving the values of the site.

The scope of the works did not include a detailed flora and fauna survey of the site and the season within which the work was undertaken (outside of the winter growing and spring flowering season) would mean some species were unlikely to be recorded during the site assessment. 1.3 THE STUDY AREA

The plan is focused upon Shire Reserve 27618 west of Bayview Drive and along the Cowaramup Brook to the Reserve boundary. The area is shown on Figure 1.

5


Figure1 – Project Area The total project area covers a 1.4 km stretch of the coastal foreshore approximately 17.8 ha in area and includes five distinct nodes:

• Zone 1 - South Point/Huzzas; • Zone 2 - Melaleuca Beach; • Zone 3 - Swimmers Beach; • Zone 4 - Cowaramup Brook to the National Park boundary; and • Zone 5 - Northpoint boat ramp and carpark area.

Cowaramup Bay is a granite basement overlain by limestone. The granite basement is exposed on the beach and on the headland at the northern end of the bay, which forms North Point. The southern end of the bay, and forming Cowaramup Point, is Tamala Limestone. Here limestone cliffs and coastal slopes rise to over 20 metres in elevation. The middle of the bay exhibits low fore dunes and is dominated by the mouth of Cowaramup Brook which enter the bay at this point. As a small north-west facing bay Cowaramup Bay is relatively sheltered, but open to wave action when swells and waves come from specific directions, particularly in winter. At such times, the beach is eroded and the profile steepened. In summer, with reduced sea action and a more southerly trend in wave activity, sand is brought back to the beach, and the profile assumes a more gentle form. 1.4 ABORIGINAL CULTURAL AND HERITAGE VALUES

SUPPLIED BY ISZACC WEBB, TRADITIONAL OWNER WITH UNDALUP ASSOCIATION:

Kaya, Nala Maat Kaya Noonduk (Hello, Our Family Welcomes You) to Wadandi Boodja (Saltwater People’s Country) – we all come together on Boodja (Country). Whilst on Wadandi Boodja we ask that you respect the land by walking softly and take the time to listen to Boodja as she Wongi (Talks). We respect the presence of the Demmala Goomala (Ancestors) whose Djanga (Spirits) reside on Boodja and whose djenna (feet) walk the land and whose Djanga Korda (heart spirit) flows through all creation. We can all benefit from the powerful sense of belonging that is offered by the cultural sounds, rhythm, spirit, art and people. This empowers us all to continue the ancient tradition of reciprocity (an exchange of mutual benefit). By showing respect and acknowledgement to our Aboriginal people and through working together, we can learn and educate each other and ourselves about the connection that we all have to Mother Earth. It is up to all of us to listen to the land, understand the connection to Country that we all have and realise how urgent it is to work together to make better decisions on how we can create that balance, ensuring sustainability for the generations to come, in order to protect and preserve the beauty of Boodja. The Wadandi people have a complex and holistic framework of understanding in their role of looking after Country. The Dreamtime is the heart of the spirituality of the Wadandi people and the traditional mythologies taught from the Elders, provided a blue print for respect and utilisation of resources in a sustainable way. It is a relationship between the people, the land and all its creatures. Throughout Wadandi Boodja there are many creation stories, in particular the ‘Waugal’ (hairy face snake) being one of the most influential creative spirits that transformed the landscape creating hills, lakes, rivers and animals, infusing it with a living spirit. Sharing this knowledge is important for others to have the understanding of, and connection to our land, to care for, respect and learn from the Wadandi land and sea management practices, as together we can all explore ways to keep “Caring for Country”. Boodja – Land, Country, Mother Earth – is our most important resource. No matter what culture or religion – all of us rely on Nala Boodja, Our Country. “Whilst living, travelling, visiting and holidaying on Wadandi Boodja (Saltwater People’s Country) we ask that you respect the area and walk softly on the country, taking the time to listen to Boodja (Country) as she Wongi (Talks) of the Season, and leave nothing but footprints”. Our vision is to share the culture, traditions, knowledge and history of the Wadandi people with the broader South West communities; to impart an understanding of the importance of Boodja (Country) and to teach the significance of and respect for the Wadandi Elders and Traditional Custodians Aboriginal Culture is the oldest living culture and the longest continuing religion in the world. To Aboriginal people the land is life. We are connected spiritually to the land, water, flora and fauna. “These are written into the country of place names and songlines. They are our kinship that connects us through cultural lore.”

“We don’t own the land, the land owns us”

7


The Wadandi people have a long association with the environment of the South West and its natural resources. We utilise the Country’s natural resources according to our lore (learning and knowledge of tradition) to look after Country. “The inter-dependence of all life within Country constitutes a harsh but essential lesson – those who destroy their Country ultimately destroy themselves.” (Hill, Bradby & Pearce, 1997). Therefore maintenance of biodiversity has always been linked to the health of the local Wadandi people both spiritually and physically.

Cowaramup Bay in the Capes region where the community of Gracetown resides, is a Cultural significant Aboriginal Heritage Site, known for the associated history of the area, many choose not to discuss, with many Cultural sites, bushfood areas that are of high importance to the local Aboriginal people of the South West. The site holds many important values with connection to the Boodja, (Country), water and the Wadan, (Ocean) with the Wadandi people.

The Wadandi people have always valued the natural resources within our Country as having spiritual meaning, providing sustainable diet and for their healing capabilities. In more recent times, natural resources have also been valued for the educational and employment opportunities they create. It is also important to note that Aboriginal environmental knowledge associated with natural resources is another key cultural value.

Wadandi Cultural Custodian, Iszaac ‘Waalitj’ Webb

1.5 ECOLOGICAL VALUES

Cowaramup Bay and Gracetown have exceptional biodiversity values due to the fact that the area is surrounded by National and Marine Park. Much of the vegetation within the Reserves is in good to very good condition and a broad range of wildlife is frequently encountered even within the house sites. One of the dominant vegetation communities within the Bay with Rottnest Island Teatree or Moonah (Melaleuca lanceolata) dominating the canopy is considered as a Priority Ecological Community (PEC) and as such is important for protection and restoration. This community is prone to disturbance by fire and access in and around plants removes understorey and young plants to replace mature plants The Granite vegetation communities within and surrounding the Cowaramup Bay coast are diverse and vulnerable to disturbance from access and fire. The open and sparse nature of the vegetation on the granite outcrops of Northpoint make these areas vulnerable to unconstrained pedestrian access. These areas are slow to recover from disturbances. A number of threatened flora species are found in and around the Bay including orchid species such as Giant Spider Orchid (Caladenia excelsa) The Cowaramup Brook is an important feature of the bay influencing the native vegetation, wildlife habitat and the marine environment of the Bay. Upstream of the project area, the Cowaramup Brook is considered to be in A Grade condition for several kilometres as it passes through the National Park. As it leaves the National Park and enters the Shire Reserve of the bay the brook drops down to B Grade foreshore. This is however, improving with past and

8


current revegetation projects restoring foreshore vegetation and it is a realistic goal to raise this section of the brook to A Grade within the life of the plan. The bay is home to a range of wildlife including relatively common species which form part of the character of the Bay and Gracetown such as Bobtails resident in backyards, priority species such South West Carpet Pythons and Quenda which are regularly spotted around town and in backyards. It is also home to threatened species such as the critically endangered Western Ringtail Possum. It is noted that feral cats and foxes are regularly sighted around town and represent a threat to these species. The shelter provided by the northwest facing bay provides an important and unique refuge within the Cape to Cape coast for a range of shorebirds particularly around the western end of Melaleuca Beach. This area provides seaweed build up in Autumn/ Winter and protection amongst the rocks and surrounding vegetation for resting/ roosting. Species utilising this area include Cormorants, Reef Egrets, Pied and Sooty Oyster Catchers, Silver and Pacific Gulls, Terns and the less common Hooded Plover. Even more aquatic species such as Black Swans and Black Ducks have been sighted here. The waters of the bay contain a range of marine values appreciated by the community both for observation and appreciation eg) snorkelling and for fishing eg) herring fishing at Melaleuca Beach. These values are recognised and (partially protected) through the recognition of the Cowaramup Bay as a ‘Recreation Zone’ within the Capes Ngari Marine Park Management Plan. Many in the community believe that this protection does not go far enough and would like to see strongly restrictions in place within the bay. The primary threats to ecological values of the bay represent increasing access and recreational pressureand climate change. Increasing populations within Cowaramup and Margaret River (and the potential future doubling of the Gracetown townsite through Landcorp proposals) coupled with growing tourism exposure and numbers result in increasing demand and pressure for recreational access to all aspects of Gracetown and Cowaramup Bay. Given the protection offered by the unique northwest facing bay, the spectacular scenery and surf and one of the few boatramps in the Capes, Gracetown will continue to attract increasing visitation both from locals and visitors. It is essential that these visitors are managed and directed in a way that minimised the impact on the beauty and ecological values of the area. Climate change represents a threat to many aspects of the Bay’s ecology through changing rainfall patterns, rising temperatures and most notably in the coastal environment, rising sea levels. Conservative scenarios predicated by the latest Intergovernmental Panel on Climate Change (IPCC) Report on Climate Change predicts sea level rises of between 0.28 and 0.65m by 2090 (with additional rises possible depending on ice sheet movements). Recent monitoring of Fremantle sea level has shown rises of 20cm since 1915 at a rate of 1.38mm/year with the past 30 years showing an average rise of approximately 3.0mm/year. Predicted sea level rise in the coming decades has the potential to seriously impact on the existing shoreline and while this prospect requires consideration, it is beyond the scope and time horizon of this report. This is covered in detail by the Shire’s Coastal Hazard and Risk Management and Adaptation Plan, 2015 and the Shire’s Coastal Monitoring Program, 2018 both prepared by Shore Coastal.

9


It is noted that the long period tides and the 18.6 year nodal cycle is projected to peak around 2023 and that this will accentuate coastal erosion during the horizon of this report 1.6 PREVIOUS WORK

It is important to recognise that this plan has been prepared with reference to a significant body of existing plans and reports that have already been completed in relation to Gracetown and Cowaramup Bay. Futhermore, many community and Shire driven projects have already achieved much throughout Cowaramup Bay in terms of Coastal protection, awareness raising and restoration. Many of these projects are on going and the current condition of Cowaramup Bay and engagement of the local community is a credit to the locals. Reports and plans considered in the preparation of this report include:

• Augusta – Margaret River Coastal Management Plan, 2005; • Shire of Augusta Margaret River, City of Busselton Coastal and Foreshore Facilities

Asset Management and Expansion Plan, 2012 • Capes Regional Boating Strategy, 2011 • Gordon’s Geotechnical Consultants Huzzas Cliff Report, 2005 • Limestone Cliff Stability Assessment, 2017 • Coastal Hazard and Risk Management and Adaptation Plan, 2015 • Coastal Monitoring Program, 2018 • Arborist’s Report – Melaleuca Beach Picnic Area, 2019 • Swimmers Beach Park – Landscape Concept Plan, 2016 • Rehabilitation Plan for Swimmers Beach, Gracetown, 2017 • Cowaramup Creeks Action Plan, 2008 • Leeuwin Naturaliste Capes Area Parks and Reserves Management Plan 81, 2015

2. METHODOLOGY

2.1 COMMUNITY CONSULTATION

The development of this plan builds upon a strong history of community involvement in management of Cowaramup Bay. The process incorporated a range of opportunities for community input and consultation in relation to the development of the plan. Consultation undertaken during the preparation of the plan included:

• ‘one-on-one’ conversations with key stakeholders or residents who were identified as having a specific interest in the area;

• discussions with locals and visitors encountered during site work; • input and comments received during the community site walks held on Saturday the 6th

April 2019; and • community submissions received during the preparation of the plan.

A site walk was conducted with Undalup Representative Iszacc Webb on the 20th February prior to commencing work on the preparation of the plan. Subsequently representatives from the following groups/ organisations were contacted:

• Undalup Association Inc. • Department of Biodiversity Conservation and Attractions; • Gracetown Progress Association; • Cowaramup Bay Boardriders; • Shire of Augusta Margaret River; • Surfing WA; and • DFES.

The purpose of the stakeholder consultation was to share information with groups identified as having a specific interest in the area. This included an overview of the process behind the preparation of the plan and detailing the objectives of the plan and seeking information on relevant values and management issues. The consultation phase provided an important insight into the views of the community and valuable feedback on year-round usage and issues impacting the bay. Key feedback from of the consultation included:

1 There is a demand for more information and understanding of aboriginal cultural values; 2 The ‘low key’ nature of infrastructure and facilities is valued by the community; 3 Environmental protection and improvement of the brook is a high priority. 4 Cowaramup Brook is much loved by locals and it is important that the cultural and

environmental values of this area are protected. Foreshore revegetation is supported; 5 Strong support exists for dune stabilisation including fencing and revegetation; 6 More focus is required on the cliff risk area around Huzzas including consistent signage,

fencing and revegetation; 7 The unique biodiversity values of the Bay and it being surrounded by National and/or

Marine Park is significant and should be a focus of awareness raising 8 Carparking pressures are experienced in most areas during peak season/ ideal surfing and

or fishing conditions – containment of inappropriate parking is required as is provision of overflow areas;

11


9 Safe pedestrian and bicycle linkage from town through to North Point is required 10 Call for support for disabled access to the water at Swimmers Beach, and 11 Melaleuca Beach is very important to locals and should be protected and enhanced

including protection of the large established Rottnest Island Tea Trees.

2.2 ON-GROUND ASSESSMENT The on-ground assessment was undertaken by Drew McKenzie during April, May and June 2019. The assessment involved the collection of detailed information on the following aspects:

• Coastal and Foreshore Erosion; • Vegetation condition and potential for revegetation; • Dominant vegetation species; • Infrastructure present; • Priority environmental weed presence; • Track and trail status; • Pedestrian access; • Recreational uses and issues; and • Baseline photo -point monitoring.

3 DESCRIPTION OF THE FORESHORE ZONES

3.1 SOUTHPOINT/ HUZZAS ZONE

The limestone cliff face dominating this zone is exposed to wind large swells and stormwater and groundwater movement from above. It is noted that this section of the bay is considered in detail as part of the 2017 ‘Limestone Cliff Stability Assessment’ by Golder Associates. The report identifies parts of this zone as a high cliff fall risk areas and contains specific recommendations in relation to managing this risk. This zone is very popular among surfers as an access and parking point for the adjacent South Point and Huzzas breaks. These are particularly popular and highly used during Winter when the Bay represents a refuge from strongly southerly and south westerly winds and very large swells. Huzzas is a very popular break for young and beginner surfers offering one of the best beginner waves on the coast. The walking path through this zone is very popular and provides spectacular views across the bay. It forms part of the Cape to Cape Track. This zone contains important memorials and significance to the community due to the lives lost in the cliff collapse of 1996. The high level of useage of this area is reflected in the provision of a formalised, bitumenised carpark, basic toilet block, picnic tables and lookout through this area. Vegetation through this zone ranges from very good through to degraded condition. The condition of vegetation is largely determined by the level of recent and historical access the area receives. This area contains a range of coastal species and vegetation with large portions of this zone dominated by Moonah or Rottnest Island Teatree. The Moonah dominated vegetation community is listed as a “Priority Ecological Community” or PEC. Parts of the Huzzas cliffs are identified as an important roost zone for shore birds. Key management issues through this zone include:

• Continued pedestrian access through and onto the vulnerable and high risk cliff areas;

• Need to protect and enhance native vegetation cover and condition for cliff stability, amenity and habitat;

• Small but highly visual areas of grassy weeds in open degraded areas around the memorials and carpark;

• Uncontrolled access to and degradation of the dunes behind the coastal track including large areas of litter and debris

• Water flow from the path at Volunteers Rest and from the Huzzas carpark down the adjacent cliff faces which is adding to instability

• Improved cliff risk signage along the top and bottom of the cliff • Protection of existing Rottnest Island Tea Tree around picnic area and pathway

and implement succession planting • Need for interpretive signage at the Huzzas lookout focused on surfing etiquette • Illegal camping and beach fires around Huzzas

13


• Desire from the Cowaramup Bay Boardriders to install a judging/ viewing platform along the Southpoint track (it is understood that this is currently being considered by the Shire in detail)

3.2 MELALEUCA BEACH

This area is made up of a narrow beach, low foredunes with a low limestone largely vegetated cliffs to the south. It is a protected, generally low energy beach which accumulates masses of seaweed during Autumn and Winter attracting fish and shorebirds. It is an area where Hooded Plovers are commonly sighted. This area contains a range of coastal species and vegetation with large portions of this zone dominated by Moonah or Rottnest Island Teatree. The Moonah dominated vegetation community is listed as a “Priority Ecological Community” or PEC. This zone also represents an attractive, protected recreational and open space area and is popular among families for fishing, swimming, dog walking and picnicing. It is much loved amongst locals and contains several low key beach access tracks, a small informal carpark, picnic tables and rustic stairs linking the Picnic area and beach to Percy street. This zone represents a designated dog exercise area. The Cape to Cape Track runs through the picnic area and up the Percy St stairs. Vegetation through this zone ranges from very good through to degraded condition. The somewhat degraded nature of the dunes are a reflection of historical access and the impact of coastal erosion. Parts of the Percy St vegetation are degraded from recent attempts to prune and damage vegetation to maintain/ expand views across the bay. Other vegetated areas around the picnic area are somewhat degraded with minimal understorey and the presence of grassy weeds. This area contains a range of coastal dune and coastal heath species and vegetation with portions of this zone dominated by Moonah or Rottnest Island Teatree. It is noted that the condition of and potential management options in relation to the Melaleucas within the picnic area were the subject of an arborist’s report undertaken in January 2019 by Arbor Guy. Key management issues through this zone include:

• Erosion and damage of beach access • Need for support, propping and succession and understorey planting of /around

the Melaleucas in the picnic area • Address pooling of water within middle of carpark • Illegal camping in carpark • Need for continued dune rehabilitation and revegetation • Succession planting, understorey revegetation within the vegetation communities

surrounding the open space/ picnic area and the cliff zone along Percy St. • Previous damage to vegetation adjacent Percy St to enhance views • Presence of priority environmental weeds eg) Norfolk Island Hibiscus • Potential conflict between dog exercise area and important shorebird zone

3.3 COWARAMUP BROOK The lower 400m of the Cowaramup Brook lies within Shire Reserve and links upstream to the Leeuwin Naturaliste National Park. It contains important Aboriginal heritage sites and a unique landscape feature and vegetation mix within the Bay. The riparian vegetation dominating the bulk of the foreshore edge is buffered upstream by adjoining vegetation. Downstream, the foreshore vegetation is adjoined by open space areas with little or exotic plantings and coastal/dune vegetation downstream of Bayview Rd. The brook represents a unique aspect of the Bay and a highly valued walk for locals. In the past, portions of this area have been used for informal camping and had picnic tables in place. Several years ago the southern bank was subject to a successful revegetation program and last year community led revegetation commenced in portions of the northern foreshore. Some portions of the brook foreshore have experienced and are considered prone to erosion following flooding last winter and diversion of flows due to a build up of significant volumes of woody debris. Vegetation along the brook is dominated by Peppermint, Marri and Karri. This area represents confirmed habitat for the critically endangered Western Ringtail Possum. It is noted that this zone previously formed part of the assessment and report prepared for the Cowaramup Creeks Action Plan from 2008. Key management issues through this zone include:

• Woody debris within brook representing potential for the creation of erosion • Control of priority woody, grassy and geophyte environmental weeds • Potential for revegetation on the north side of the brook • Sensitive management and maintenance of pathway • Increasing unauthorised vehicle access of the Western Power track above the

brook

3.4 SWIMMERS BEACH This zone is dominated by degraded sand dunes on the beachfront with the large carpark located directly behind the foredunes. Behind the dunes north and south of the carpark, granite outcrops dominate. The foredunes extending north from the carpark gradually improve in condition towards Northpoint at which point they are considered to be in excellent condition. This zone represents the most popular swimming beach in the bay and hosts Vac Swim classes over the Christmas holidays and the Bay swim at Easter. The carpark is currently not formalised into marked bays and is not bituminised. It is noted that the carpark acts as an informal overflow parking bay for some boatramp users and northpoint surfers. It also has the toilet block and open space area south of the carpark. The degraded dunes are dominated by weed species such as Sea Spurge, Dune Onion Weed and Rose Pelargonium. The vegetation around the open space and picnic area represents a mix of native coastal species and a range of introduced landscape and weed species. It is noted that there has previously been a landscape concept plan prepared for the open space area surrounding the toilets and a basic revegetation plan for the dunes. Key management issues through this zone include:

• Degraded, weed dominated dunes • Old, half buried bollards • Underutilised open space area around the toilets • Presence of priority environmental weeds • Need for safe pedestrian access between cars and dunes • Access required around the granite rock to the north of the carpark – including for

Cape to Cape track walkers • Need for disabled access into the water • Demand for increasing parking and overflow parking from northpoint

23

3.5 NORTHPOINT

Northpoint is a granite dominated landscape with iconic exposed granite outcrops and shallow soils supporting signature granitic plant species with a healthy strip of coastal heath and native foredune vegetation between the carpark and the beach. Two small but unique springs occur within this zone creating ancient and unique small patches of wetland/ riparian species within a zone of dominated by coastal heath and granite species. Northpoint represents a major focus for surfers with the world class righthand break considered one of the premier breaks within the region. It has received increasing exposure in recent years through media and social media coverage and its recent addition as a backup break for the World Championship Tour’s Margaret River Pro. The area is popular for launching boats and jetskis. The point and beach area is popular among fishermen and represents part of the Cape to Cape Track. This zone contains a relatively recently upgraded boatramp, carpark facilities, footpaths and informal lookouts. Escaped fires and burns have been an issue within this zone with parts of the granite and surrounding vegetation still recovering from previous burns. It is noted that the peaty wetlands burnt very hot and for vastly extended period during recent fires. Key management issues through this zone include:

• Crowded and overloaded carpark on good surf and fishing days • Braided tracks from carpark out to Northpoint jump off • Lack of toilets and evidence of toileting in the surrounding vegetation • Parking pushing on to boatramp beach and off the top track • Eroding path from the top track to boatramp beach • Degraded spring area near the trailer parking bays • Priority environmental weed present near Bayview Drive • Need for safe pedestrian access along the edge of Bayview Drive to northpoint

carpark and uphill to the ‘top’ carpark • Concerns were raised about charter group operators and clientele crowding up the

limited carspaces available to independent recreational users.

4 MANAGEMENT RECOMMENDATIONS

The following recommendations have been developed based on the objectives of the plan, site assessment, literature reviews and community consultation. The recommendations are broken into the five management zones with overarching strategic recommendations up front.

OVERARCHING STRATEGIC MANAGEMENT ACTION RECCOMENDATIONS # RECOMMENDATION PRIORITY

I Acknowledge and note the significant Aboriginal Cultural values and sites located within and around the area and consider during all future management decisions.

H

II Explore with traditional owners potential options for running of seasonal or annual Aboriginal Cultural walks through the bay to increase understanding and respect amongst the community.

H

III Ensure Traditional Owners are consulted during the planning stages of on ground work and where appropriate obtain Reg 10 approvals and/or have aboriginal monitors present during the work.

H

IV Consider, implement and respond to Coastal Management and Monitoring recommendations detailed within the ‘Shire of Augusta Margaret River Coastal Monitoring Program’ 2018 in relation to Cowaramup Bay.

H

V Involve the community in the implementation of this plan as much as possible to increase community capacity and ownership of projects and utilise the community’s skills and knowledge. Key groups to involve include school groups, Cowaramup Bay Boardriders, school students and aboriginal youth networks.

H

VI Change the vested purpose of Reserves 27618 from “Recreation” to “Conservation and recreation” to more accurately reflect the current value and management intent of the area.

M

VII Consider projected sea level rise in all future projects and ensure investment in infrastructure is placed well back from the current high water mark.

H

VIII Support and assist the ‘Friends of Gracetown and Cowaramup Bay’ in their important role of involving the community in coastal issues and in the implementation of a range of aspects of this management plan.

H

IX Develop/ update a series of interpretive signs to be placed at key viewing locations around the bay (including on DBCA tenure) that covers a broad range of topics such as indigenous heritage, geology/ geotechnical, the marine system, local flora and fauna and shorebirds in order to increase locals and visitors understanding of the systems that underpin the recreational and environmental values of the Bay.

H

X Seek funding to run a series of conservation based interpretive walks aimed at providing locals with a better understanding of the bay’s natural environment and high it can be protected and restored.

H

XI Continue photo-point monitoring at key locations. H XII Control high priority environmental weeds adjacent to the project area known to represent a risk to the project area eg) Geraldton

Carnation Weed and Arum Lily H

XIII Investigate Land for Wildlife listing for the reserve to recognise the important biodiversity values and the significance of this to the local community.

H

XIV Continue the close collaboration between DBCA and the Shire with regard to the Bay in order to support consistent management cross tenure.

1.0 INTRODUCTION

1.1 BACKGROUND

The Shire of Augusta Margaret River is committed to the protection of biodiversity, enhancement of recreational values and working with and supporting the community for the protection and management of the values of Shire vested reserves. As part of this commitment to the protection of biodiversity, the Shire committed to develop an Action Plan to guide management, weed control and revegetation within the portions of Redman Brook running through Flinders Bay. The intention of this plan is to build upon the Protection and Management Plan for Flinders Bay developed in 2017 which provided broad direction for the management of the area. The Redman Brook Plan provides the next level of detail that is required to successful inform the community and guide the implementation of work along the creekline The Redman Brook and Flinders Bay hold special significance for local residents and visitors As such, the preparation of this plan included community consultation including both an onsite community meeting and a call for written submissions.

1.2 FLINDERS BAY PROTECTION AND MANAGEMENT PLAN 2017 The protection and management plan for Flinders Bay (FBPMP) developed in 2017 identified some broad based recommendations that covered Redman Brook that were important to consider in the context of the preparation of this plan. Key relevant recommendations included:

• Piping and turfing of the drain portion of Section • Undertake staged weed control and landscaping

within Redman Brook using native species which ‘match’ with the existing aesthetic.

1.3 SITE DESCRIPTION

This plan covers the downstream most 300m of the Redman Brook where it runs through the settlement of Flinders Bay and enters the ocean. Redman Brook is a picturesque small waterway that is an important part of the environment and amenity of Flinders Bay. As with the broader Flinders Bay has important environmental, cultural and historical significance. For the purposes of this plan it is broken into three sections (see Figure 1 below): Section 1(~78m) (Reserve 24653) Coast to Davies Rd: The mouth of the Brook and last ~30m is dominated by native vegetation and native revegetation – the next ~40m to Davies road represents a weed dominated artificial drain with steep sides and very little native vegetation.

52

Section 2(~93m) (Reserve 24573) Davies Rd to Peppermint Drive: The western edge of this section represents open parkland cleared and landscaped, managed grass and trees. The eastern portion represents vegetated creekline with weed dominated understorey and groundcovers with a largely mature and good canopy cover of WA Peppermints. Section 3(~115m) (Reserve 24538) Peppermint Drive to Wishart Rd: The northern portion of this section is a narrow reserve with largely weedy vegetation dominating the stream channel adjoined by parkland cleared space on the western side of the reserve. The southern portion is very over grown with a mix of peppermints, some natives and a broad range of woody, climbing, geophyte and herbaceous weeds. 1.4 PURPOSE AND SCOPE OF THIS PLAN

This Action Plan is intended to be an informative, practical and easily applicable tool to help facilitate collaborative and strategic, management of a significant community asset. The actions and recommendations are intended to provide a strategic and prioritised approach to the reserve management in order to ensure the most efficient and effective investment of limited resources in the reserve. The scope of the plan includes consideration of the following values:

• Cultural values; • Biodiversity; • Recreation; and • Amenity.

The actions and recommendations have been developed following on ground assessment of reserve and consultation of the community and stakeholders with a keen interest in the reserve.

1.5 COMMUNITY CONSULTATION

Community consultation was a key element of the project and important in the development of the management recommendations of the plan. The preparation of this plan included four elements:

1. Conversations with stakeholders with a key interest in the Redman Brook; 2. Community onsite meeting and field walk; 3. Provision for consideration of written submissions for the community; 4. Formal advertising and public comment period of the draft plan.

Stakeholders contacted in relation to the development of this plan included: • Shire of Augusta Margaret River - Asset Services, Planning Services, and Operations • Friends of Flinders Bay • Neighbouring landholders • Augusta Land and Coast care • Augusta Community Nursey • Neighbouring landholders • Interested community members • Representative of Undalup Association

The onsite community meeting was held on the afternoon of Saturday the 20th of April 2019. This meeting was specifically scheduled to coincide with the Easter long weekend and maximise the opportunity for landholders able to attend. The meeting was well attended with over 30 people present and it provided an opportunity for the community to hear about the project and to provide comment, feedback and ideas.

53

In addition to the feedback received during the site meeting, a number of written submissions were received providing additional detail or feedback in relation to specific elements within the scope of the plan.

54

2. VALUES 2.1 ABORIGINAL CULTURAL VALUES (SUPPLIED BY ZAC WEBB, TRADITIONAL OWNER WITH UNDALUP ASSOCIATION)

Aboriginal people's values and beliefs are based on an understanding of the world that integrates the spiritual with the material and emphasizes the individual's relationship to community. Aboriginal people have unique worldviews, distinct cultures, and ways of life, and a range of traditions and practices that are fundamental to supporting the well-being of children, families and communities. Cultural respect is at the centre of culturally competent policy, practice and service delivery.

Aboriginal culture is a living Culture and is based on holistic understanding of people sustained by, and sustaining, Country – a cycle of continuing existence.

Sharing this Cultural knowledge is important for others to have the understanding of, and connection to our land, to care for, respect and learn from the Wadandi land and sea management practices, as together we can all explore ways to keep “Caring for Country”.

Aboriginal Culture is the oldest living culture and the longest continuing religion in the world. To Aboriginal people the land is life. We are connected spiritually to the land, water, flora and fauna. These are written into the country of place names and songlines. They are our kinship that connects us through cultural lore.

The Wadandi people have a long association with the environment of the South West and its natural resources. As Traditional owners of the South West corner of WA, we have family ties to this Country with a strong cultural, language and historical connection to this land. We utilise the Country’s natural resources according to our lore (learning and knowledge of tradition) to look after Boodja (Country).

The Wadandi people have always valued the natural resources within our Country as having spiritual meaning, providing sustainable diet and for their healing capabilities.

Our Key Cultural Values:

• The Cultural environmental knowledge associated with natural resources is respected and maintained.

• Ensuring that connections to Country are recognised and respected. • Aboriginal Culture and Heritage involves conserving Country with and by Aboriginal people

and communities.

The Wadandi people have a complex and holistic framework of understanding in their role of looking after Country. The Dreamtime is the heart of the spirituality of the Wadandi people and the traditional dreaming stories taught from the Elders, provided a blue print for respect and utilisation of resources in a sustainable way. It is a relationship between the people, the land and all its creatures.

It is up to all of us to listen to the land, understand the connection to Country that we all have and realise how urgent it is to work together to make better decisions on how we can create that balance, ensuring sustainability for the generations to come, in order to protect and preserve the beauty of Boodja.

55

It is vital that the Wadandi people and the Traditional knowledge they have to offer are considered in the development of strategies to manage the natural resources of the South West of Western Australia.

Wadandi Cultural Custodian, Iszaac ‘Waalitj’ Webb 2.2 HISTORICAL VALUES

Flinders Bay is a registered historical settlement with a documented history dating back as one of Western Australia’s oldest settlements. Originally known as ‘The Whaling’, Flinders Bay is recorded as having British and American whaling boats frequent the Bay as early as 1803 significantly predating settlement. The rich history of Flinders Bay is recognised within the Town Planning scheme and there exists a number of Planning Controls to ensure that the historical character is retained. 2.3 NATURAL VALUES

Whilst some parts of the brook lack native vegetation and others are considered highly degraded in terms of remnant vegetation condition, the system retains a number of natural values. The small patch of remnant native vegetation near the mouth of the brook is considered in good to very good condition. Areas of mature and well linked Peppermint canopy (eg through Section 2) provide good feed trees and habitat for the critically endangered Western Ringtail Possum (WRP). Whilst not a target of the plans fieldwork dreys (nests) were noted in the foreshore vegetation. The community reported that the brook contains a healthy and diverse bird and frog population and it is important to note that weed and exotic species can and do provide habitat for native wildlife. For example woody weeds can contain WRP dreys and caution would be needed when removing woody weeds from the Brook. The brook provides a linkage between the Leeuwin Naturaliste National Park and the coastal foreshore although much more intact connections exist to the north and south. It is important to note that the brook’s vegetation is important in preventing erosion and helps capture sediment and litter and filters other pollutants entering the brook through stormwater. 2.4 RECREATIONAL VALUES

The Brook and its immediate surrounds contain a range of recreational values including:

• Walking links to trails and the beach and through the settlement; • Opportunities for passive recreation within the open space with seating at various locations;

and • Birdwatching and appreciation.

2.5 AMENITY VALUES

The brook provides important scenic amenity and green space for the settlement and in particular neighbouring landholders.

56

3. MANAGEMENT ISSUES 3.1 ENVIRONMENTAL WEED THREATS The vast majority of the bushland is free of priority environmental weeds, however, a number of isolated populations or clusters of priority environmental weeds are found within the reserve and adjoining road reserve or private property and represent a high priority for control and or containment. These infestations can be summarised as follows: Woody Weeds:

• A range of woody weeds are present across the three sections many of which represent a priority for control including: Norfolk Island Hibiscus (Lagunaria patersonia), Sweet Pittosporum (Pittosporum undulatum), Mirrorbush (Coprosma repens), Blackberry (Rubus anglocandicans) and Edible Fig (Ficus carica).

Geophytes:

• Arum lily (Zantedeschia aethiopica) was recorded within Sections 2 and 3 and is considered to have the potential to spread and dominate not only large portions of the brook but other adjoining and nearby bushland.

Vines and climbers • Dolichos Pea is a particular issue through the brook with hotspots including the native

vegetation near the mouth and significant portions of Section 2 where is smothering vegetation and trailing up into the canopy.

• Nasturtium particularly within Section 2 has the potential to dominate and spread if left uncontrolled;

• The presence of Madiera Vine (a ‘Weed of National Significance’) - within section 3 is a high priority as this species is otherwise unrecorded within the Shire and is considered to be a high priority for control particularly in foreshore areas.

• The presence of Climbing Asparagus Fern (Asparagus plumosus) (also a ‘Weed of National Significance’) - within section 3 is a high priority as this species is otherwise unrecorded within the Shire and is considered to be a high priority for control particularly in foreshore areas.

Other: • Perrennial grasses, particularly kykuyu grass is invading and threatening much of vegetated

and revegetating portions of the foreshore. • Bullrush (Typha orientalis) is particular dominant within parts of Section 2 • Cape Gooseberry (Physalis minima) is dominant in parts of Section 2 preventing other

species from establishing. 3.2 ACCESS MANAGEMENT

The fact that the majority of the foreshore contains parts of which are open space/ parkland cleared mean that pedestrian access is facilitated along much of the Brook. It is noted, however, that pedestrian access along the last 50m of Section 3 through to Wishart Rd is not provided for and is difficult due to encroachments from neighbouring properties into the foreshore reserve and due to the overgrown nature of this section. Re-establishing this pedestrian link (while recommended in the Protection and Management Plan for Flinders Bay) was strongly supported by some residents and opposed by others.

57

3.3 FIRE CONSIDERATIONS Consultation with the local Bushfire Risk Management Planning Co-ordinator has suggested that the risk posed by the presence of dense vegetation in close proximity to houses needs consideration. Important considerations in relation to this risk and potential changes to weed loads and revegetation are as follows:

• Provision of access to the length of Brook adjacent to houses is favourable – particularly within Section 3 where thick vegetation adjoins houses and good pedestrian (hose) access is not currently provided;

• Removal of some priority environmental weeds may help reduce fuel loads and help mitigate risk; and

• Where revegetation is proposed is should be of a nature such that some separation is retained between the understorey and the canopy to help prevent spread of fire into the canopy.

It is noted that portions of Section 3 are particularly overgrown (mainly with Woody Weeds and vines) potentially representing high fuel loads with associated fire risk. 3.4 HYDROLOGY, FLOODING AND FLOW

There are multiple potential issues regarding the hydrology of the brook that require consideration including:

• Multiple residents reporting a dramatic reduction in flow through the Brook in recent years; • Potential for Saltmarsh mosquito breeding conditions (and associated disease issues) created

when saltwater enters the brook and pools during especially high tides or storm surge especially in early to mid autumn;

3.5 NON- NATIVE EXOTIC PLANTS WITHIN THE BROOK

The Brook has had a long history of non-native species such as Canna lilys, Hydrangeas, Treeferns etc existing amongst native vegetation within the waterway. Although some of these are recognised as environmental weeds within riparian systems such as Redman Brook, there is a view amongst some within the community that these species should be retained and even replaced as part of ‘revegetation’ plantings.

4. ACTION PLAN 2019 - 2024

The following management recommendations have been developed based on the objectives of the plan, site assessment, literature reviews and stakeholder and community consultation. The recommendations have been grouped into the three management sections with additional overarching strategic recommendations up front.

OVERARCHING STRATEGIC MANAGEMENT ACTION RECCOMENDATIONS # RECOMMENDATION PRIORITY

I Acknowledge and note the significant Aboriginal Cultural values and sites located within and around the area and consider during all future management decisions.

H

II Ensure Traditional Owners are consulted during the planning stages of on ground work and where appropriate obtain Reg 10 approvals and/or have aboriginal monitors present during the work.

H

III Involve the community especially the Friends of Flinders Bay in the implementation of this plan as much as possible in order to increase community capacity and ownership of the brook and its management. Other potential groups to involve include Augusta Primary School, Augusta Land and Coast Care, Augusta Community Nursery and aboriginal youth networks.

H

IV Update the vested purpose of Reserves 24538, 24537 and 24653 from “Park, pipeline and drain”, “Recreation and drainage” and “Recreation and Camping” respectively to more accurately reflect the current value and management intent of the area and include the conservation values of the brook.

M

V Support and assist in the establishment of a ‘Friends of Redman Brook’ in their important role of involving the community in coastal issues and in the implementation of a range of aspects of this management plan.

H

VI Seek funding to run a nature based interpretive walk aimed at providing locals with a better understanding of the brook’s and bay’s ecological values and how it can be protected and restored.

H

VII Continue photo-point monitoring at key locations. H

VIII Control high priority environmental weeds upstream and adjacent to the project area known to represent a risk to the brook eg) Dolichos Pea, Sweet Pittosporum and Arum Lily

H

IX Address the apparent encroachments into the reserve by adjoining private garden beds and infrastructure. M

X Investigate changes in hydrology and potential changes and diversions within the broader catchment. M

SECTION 1 MOUTH TO DAVIES ROAD # RECOMMENDATIONS PRIORITY

1.1 Undertake control of the isolated occurrences of priority environmental weeds within this zone including: • Arum lily; • Dolichos Pea; • Kikuyu and Buffalo grass; • Nasturtium; • Blackberry; • Oleander.

H

1.2 Continue the revegetation program and infill planting immediately west of the footbridge H 1.3 Review the recommendation of the FBPMP to Pipe and Turf the drain portion of Section 1 and strongly consider

revegetation and rehabilitation of creekline vegetation. There is the potential to reinstate the ecological and amenity values of this stretch through battering of the banks (or just the southern bank and revegetation. This concept appears to have the support of many within the community. Investigation of this option would require detailed consultation with the Friends of Flinders Bay.

H

1.4 Where possible, retain the existing plantings of New Zealand Christmas Bush – at least until revegetation of the brook has established and provides a food source for the Western Ringtail possum and canopy connection between Section 2 and the coast.

M

1.5 Consider the need to fence/ bollard the sides of the drain section prior to revegetation to address potential safety issues associated with the bank steepness.

H

1.6 Get technical advice around the need for and nature of required interventions to minimise salt marsh mosquito breeding. M

SECTION 2: DAVIES ROAD TO PEPPERMINT DRIVE # RECOMMENDATIONS PRIORITY

2.1 Undertake control of the following high priority environmental weeds within this zone to prevent further spread and domination:

• Arum lily; • Dolichos Pea;

H

2.2 Contain and prevent spread of other priority environmental weeds not removed in the life of this plan including: • Bullrush (contain and deseed to prevent spread); • Mature Sweet Pittosporum; • Mature Willow.

H

2.3 Progressively and in a staged manner weed and revegetate the small revegetation cells identified within Figure 5. H 2.4 Create targeted strategic ~1m weed free patches within the creekline vegetation to plant clusters of native rushes, sedges

and kangaroo paw. H

2.5 Protect through minor hand weeding and judicious selective herbicide control: Existing isolated natives (especially Sword sedge, WA Peppermints and Pale Rush); Clustered native plantings; Revegetation cells

H

2.6 Establish a narrow herbicide maintained barrier between the grassed open space zone to the west and the creekline vegetation. This will delineate between the zones managed for landscaping and open space versus that managed for foreshore protection.

H

2.7 Install low minor rock riffle sections through the creekline in order to capture sediment and create diverse flow conditions M 2.8 Create small garden beds around some of the existing mature trees and plant to native and non-weedy exotic species as per

the species list attached as Appendix 1. M

2.9 Install log seating and benches within the landscaped portion of the Section. H 2.10 Identify location that will allow machine access to the brook to remove the build-up of sediment around the drainage

outlet (as required) while minimising disturbance of the area. M

SECTION 3: PEPPERMINT DRIVE TO WISHART RD # RECOMMENDATIONS PRIORITY

3.1 Undertake control of the following high priority environmental weeds within this zone to prevent further spread and domination (it is noted that addressing a number of these woody weeds will also reduce fuel loads and fuel connection up into the canopy):

• Arum lily; • Norfolk Island Hibiscus; • Madeira Vine; • Climbing Asparagus Fern; • Edible Fig. • Honey suckle

H

3.2 Progressively contain lower priority environmental weeds (it is noted that addressing a number of these woody weeds will also reduce fuel loads and fuel connection up into the canopy):

• Ivy; • Fishbone fern; • Treefern • Canna lily.

H

3.3 Progressively and in a staged manner weed and revegetate the small revegetation cells identified within Figure ??? near Peppermint Dr

M

3.4 Reinstate informal path along the western edge of the Brook in consultation with adjoining landholders. H
