Committee Awards to Geoff Cockerton, David Venning and Luke Sweedman

Revegetating the Future and the next Seminar

There have been some big changes in the Management

committee. Perennial committee members Geoff Cockerton

(Former Chairperson), David Venning (Former Chairperson ) and

Luke Sweedman (Former Vice Chairperson) all stepped down

after each serving diligently for over 10 years. We all thank them

for their passion and dedication toward the state’s revegetation

industry.

The new Management Committee has a challenging year ahead! Firstly

is the formal launch of the Native Seed Accreditation system. The aim

of the System is to ensure buyers that the supply of an accredited

seed batch is of a certain standard as regards the quality, harvesting

techniques, processing, storage, provenance and purity of the seed

lot. The committee is busy liaising with major seed buyers in the

benefits in adopting the system and requesting for accredited seed in

future works. Accredited seed collectors and suppliers can promote

their endorsement to seed buyers using the Accredited Seed

Collector/ Supplier logo (right) in their marketing and the Accredited

Seed Logo (right) on their seed batches. More information on

accreditation can be found on our webpage.

Secondly, we plan to hold another two day seminar around mid-

September this year. Our previous seminars have been extremely

popular and we have received much constructive feedback to help

ensure this seminar is even more beneficial our broad audience of

members. The program theme is “Setting the Standards” and session

themes are being finalised. We hope to put out the call for suitable

presenters very soon.

Stay tuned for further details on these events and other related

information with our emails, Facebook page and webpage. And

please contact us if you have an interesting article you would like us to

include in our next newsletter.

Until then, I look forward to seeing you in September!

The 202020 Vision: 20% more urban green space by 2020

The 202020 Vision is a not-for-profit, collaborative initiative that is

working with private sector, all-levels of government, academia and

expert individuals to see an increase in urban green spaces in our

cities, which are currently in decline. The 202020 mission is to create

20% more green space in Australia’s urban areas by 2020. Such an

increase can greatly improve the social, economic and environmental

values within the cities. This will require mass planting of and retaining

trees and vegetation in as many urban niches as possible, including

street verges, parks, reserves and in private and commercial

properties.

More information on 202020 can be found on the following website:

National Seed Science Forum

The National Seed Science Forum was recently held in March 2016 at

Mt Annan Botanic Gardens. Committee member David Hancock was

one of 140 seed specialists from around the country joined with a

number of overseas presenters and attendees to exchange the latest

information in seed science, storage, germination and related issues.

Of particular interest were the presentations addressing viability of long

term low temperature storage and the recent breakthroughs in

germination processes for Persoonia and other difficult species.

The SERA Standards for Restoration in Australia was launched by

Threatened Species Commissioner Gregory Andrews and the Board of

SERA lead by Professor Kingsley Dixon. A comprehensive report on

the Forum will be prepared for a future RIAWA newsletter.

Green Growth Plan

The Perth and Peel regions are projected to grow to 3.5 million people

by 2050 – an increase of almost 70 per cent on our current population.

Supporting this growth and delivering an efficient and livable city while

protecting our unique natural environment is a significant challenge.

The State Government has prepared the draft Perth and Peel Green

Growth Plan for 3.5 million (Green Growth Plan) to meet this challenge.

The Green Growth Plan aims to deliver a comprehensive environmental

program for the protection of both Commonwealth matters of national

environmental significance and State environmental values.

In this context the draft Green Growth Plan aims to deliver two critical

outcomes:

• Cutting red tape by securing upfront Commonwealth

environmental approvals and streamlining State environmental

approvals for the development required to support growth to 3.5

million people

• Unprecedented protection of our bushland, rivers, wildlife and

wetlands through implementation of a comprehensive plan to

protect our environment.

Part of the Green Growth Strategy involves on-ground activities such

as:

• revegetation and rehabilitation, focusing on improving habitat

quality for multiple species and restoring and improving habitat

connectivity across the landscape.

• management actions to address threats such as weeds, disease,

uncontrolled access, fire and feral animals for the purpose of

improving habitat condition and quality.

NEWS AND EVENTS OF INTEREST


Simon Robinson

It is vital for any revegetation practitioner working in the southwest

to be aware of the threat of dieback and how it may be spread.

The fundamental aim of Dieback hygiene is to prevent the introduction

and/or spread of Phytophthora Dieback in protectable uninfested

vegetation. The human-related spread of Phytophthora Dieback

generally occurs through clumps of soil being picked up on vehicles/

machinery/boots in infested areas, and then deposited while traversing

uninfested areas. The risk of collecting infected soil and transmitting

the pathogen is greatly increased during wet/damp conditions, and the

simplest way to minimise the risk of disease spread is to work in dry

soil conditions whenever possible.

There are four high risk vectors that lead to the introduction and/or

spread of Phytophthora Dieback:

1. Contaminated vehicles or machinery

2. Contaminated materials

3. Uncontrolled access

4. Poor hygiene procedures

To manage the risk associated with these vectors, a Hygiene

Management Plan (HMP) is required. A HMP identifies areas and

activities in which there is a risk of disease spread/introduction

occurring and outlines the strategies to be employed to eliminate/

mitigate these risks. For a HMP to be developed, Phytophthora

Dieback occurrence mapping must first be undertaken. This mapping

will identify any infested areas, and the lines delineated in the field will

create boundaries between infested areas and other categories,

allowing for clean down points to be implemented.

Cleandown/inspection points

The basic principles for cleandown are:

• Clean on entry for Dieback free

• Clean on exit for Dieback infested

The two main types of inspection/cleandown point are vehicle/

machinery washdown pads and boot cleaning stations. Vehicle

washdown areas typically comprise a well drained pad that can be

PHYTOPHTHORA DIEBACK HYGIENE REQUIREMENTS FOR WORKING IN NATIVE VEGETATION

Deceased Banksia and Xanthorrhoea specimens in an infested section of Swan Coastal Plain Banksia Woodland. - Simon Robinson

cleaned, an effluent collection point and high pressure water system,

fire unit or pressurized wash down spray unit.

Boot cleaning stations typically contain brushes, scrapers and/or foot

baths. Footbaths may use a disinfecting agent such as:

• 1-0.5 % Bleach

• 70 % Methylated Spirits

• Phytoclean®

Where an inspection identifies that a vehicle, machine, footwear etc.

requires cleandown, it is important that the appropriate cleandown

method is employed. In dry soil conditions, where relatively small

amounts of soil/plant material that can be easily removed are present,

a dry brushdown is the preferred method of cleandown. Eliminating

the use of water during cleandown means that additional moisture is

not being introduced to the area, which would make conditions more

favourable for the pathogen. Washdown may still be required in dry

soil conditions, as it may not be possible to remove all material with a

brush.

In damp/ wet conditions or where material cannot be effectively

removed with a brush, a washdown will be required. If adequate

cleandown cannot be achieved at the cleandown point, then the

vehicle, machinery or person should not proceed past the cleandown

point. Instead, the vehicle, machinery or footwear must be taken to a

location where it can be effectively cleaned, before returning and

entering the protectable area.

Note: Thin layers of dust & grime adhering to the sides of the vehicles

need not be removed.

Legislation and Guidelines

Legislation relevant to Phytophthora Dieback is contained in the

following State and National Acts and International Agreements.

WA Government Legislation

Wildlife Conservation Act, 1950

Conservation and Land Management Act, 1984 (amended 2012)

• Declaration and classification of Land (Disease Risk Areas – DRA)

Conservation and Land Management Regulations 2002


Forest Management Regulations 2002

• Application of conditions to enter DRA

• Environmental Protection Act 1986

• Applies regarding the general provisions for causing ‘pollution’ or ‘environmental harm’

Commonwealth Legislation

Environment Protection & Biodiversity Conservation Act, 1999

International Agreements

IUCN International Convention on Biological Diversity, 1992

The organisation responsible for the development of policies and the enforcement of regulations is the Department of Parks and Wildlife. Specific details of the policies, regulations, roles, responsibilities, penalties etc. can be found on pages 27 - 40 of the 2003 Department of Parks and Wildlife publication called Phytophthora cinnamomi and Disease Caused by it Volume I – Management Guidelines (link below).

Management Guidelines

It should be noted that all the current DPaW documents (Best Practice and the Management Guidelines Vol. 1) are currently under review and should, by the end of 2016, be replaced by a new Guidelines document and a Management Manual. Some of what is in the existing Management Guidelines Vol. 1 will still be relevant i.e. the Commonwealth EPBC Act; the role of the CALM Act 1984 and regulations, the Wildlife Conservation ACT 1950 and the forest regulations.

However, it is not yet known exactly what impact the new BAM Act and the new Biodiversity Act will have on management – that will be in the new documents. One very important recent change is the new departmental Policy Statement 3 (see attachment) which places much greater emphasis on risk based management and hygiene management planning for planed disturbance activities. The policy is guiding all current review and revision work.

There are also various best practice documents and management guidelines for specific industries and groups. These documents can be found in the link. https://www.dwg.org.au/publications

BUSHFIRE PLANNING FRAMEWORK

The State Government has announced a package of reforms to help protect lives and property against the threat of bushfires throughout Western Australia. These reforms introduce new requirements for people intending to develop and/or build in bushfire prone areas, including the need to assess a property’s bushfire risk and take additional construction measures to limit the impact of bushfires.

These changes have important implications for those involved in designing revegetation and soft landscaping near important assets such as homes and buildings. A significant increase in the amount of vegetation may increase the fuel loads and which in turn could result in increasing the asset’s building code standards. To understand more about how this may affect your design, visit the following website:

The Gateway WA Project linking Perth Airport to adjacent major

arterial roads is the largest infrastructure venture undertaken by

Main Roads WA. The one billion dollar project is funded from

contributions from both Federal and State governments.

This involves major upgrades to the road network surrounding Perth

Airport as well as the freight and industrial hubs of Forrestfield and

Kewdale. The project is driven by an expected doubling of passenger

air travel and road freight over the next ten years. Air passenger

numbers are currently sitting at 10 million. Over the last 3 years

passenger numbers have increased at a rate equivalent to 15 years of

previously anticipated growth. Expectations now add up to an

increase to 20 to 25 million by 2031.

With a footprint of 175 hectares this transport interchange, involving

air, road and rail services, will facilitate movement of people and goods

essential to the economy of WA. Respect for the environment in the

project area has many facets including managing flora and fauna

impacts, noise mitigation, aboriginal heritage, visual amenity

landscaping and revegetation.

Two fit for purpose soil carbon products are being supplied locally for

the project. One is a revegetation mulch for large areas, particularly at

the southern end of the project centred around the Roe Highway -

Tonkin Highway interchange. The other is a high humus mature

composted product and this is being used for mature tree planting

works in the landscape.

With such a large footprint what are the ways of reducing impact on

the environment? Established trees have been marked and retained

where possible and there is some salvaging of plant material for

revegetation by means of direct transplanting or the gathering of

cuttings and seed. Trapping and re-locating of fauna found in the

project area has been undertaken as has the installation of fences to

protect fauna such as the Southern Brown Bandicoot from predation.

Revegetation of the site will be accomplished using local native

species of plants. Rare and endangered plants will be transplanted

into the adjacent Dundas Reserve in Forrestfield.

Within the project area are four endangered species of national

significance, two plants and two birds. On the plant side of things

there is the Wavy Leaf Smokebush (Conospermum undulatum) a long

- lived shrub present around both the Roe and Tonkin highways. This is

listed as vulnerable and the concerns about this plant centre on

dieback disease, weed infestation as well as altered fire regimes as

this is a fire dependent variety. The other threatened flora is the rare

Macathuria keigheryi, which is generally only found if a fire has

occurred in the previous few years.

Canaby’s Black Cockatoo is classed as “Endangered”. The region

also provides habitat for the Forest Red Tail cockatoo which is classed

as “Vulnerable”.

Soils in the project area are mostly classified as Bassendean sands,

some of the least fertile natural soils on Earth. Most replanting in

disturbed sites such as this occurs in imported sub soil and as a result

there is very little organic matter to kick start new plants. The

incorporation of composted and recycled organic materials helps new

plants by bringing soil biology to the impoverished sand.

Dieback disease and weeds are already present in the project area so

it is essential that any soil improvers or mulch materials introduced to

the site be composted to ensure freedom from weed and disease

organisms. Also mature soil carbon products are actually antagonistic

to pathogens such as dieback disease.

There is a doubling of the environmental benefits here as soil

improvers used in the project are all waste materials, rescued from

going to landfill and converted into soil carbon by a sophisticated,

controlled composting system.

Around 30,000 cubic metres will be delivered to the construction site

over 5 months. A specific ‘fit for purpose’ blend has been prepared for

the Gateway project for local area native plants that have a lesser

demand for nutrients. This uses as its main input, verge collected

greenwaste from several city councils.

For the first time at a large scale, cuttings of key ecological species are

being used in southwest Australia’s biodiversity hotspot. While seed

can be easily collected from most native species, collecting seed from

some key functional species is difficult and is often not cost effective.

An example is Adenanthos cuneatus, an ecologically very important

species which has not been used in large scale revegetation to date.

A.cuneatus, also known as coastal jug flower, is a spreading shrub in

the protea family, and is a key functional species as the flowers, which

are borne over a long period of the year, provides nectar over an

extended period. It is an important food source for a number of fauna

species, including honey possums, silver eyes, honey eaters and

particularly the western spinebill. Sandplain (Kwongan) ecosystems

can have a high vegetation cover of Adenanthos (0-2m height class)

and this species forms a key structural element in these ecosystems.

Spreading and dense Adenanthos bushes are long lived and provide

habitat for many native animals. These characteristics also play a key

role in preventing the establishment and proliferation of perennial grass

weeds such as veldt grass and love grass.

The absence of this species in revegetation projects in the Porongurup

to Stirlings linkage area and the Stirlings to Fitzgerald linkage area was

noted in 2012. During that year another attempt was made in an area

where previous revegetation attempts had failed. It was clear during a

site assessment/review that direct sowing natives with improved

approaches would not alone deliver the result that the conservation

group were after – Adenanthos cuneatus was absent from the

proposed seed and seedling lists! Adenanthos cuneatus was a major

player at this site (up to 50% veg cover) but there was no cost effective

method to collect seed from it.

Cutting material was harvested from 10 wild plants growing in the

South Stirlings and cuttings were struck at the Dept of Agriculture’s

propagation facilities in Albany. Cuttings from 8 of the 10 mother plants

struck, though the strike rate was better from some individual than

others. This trial showed that the production of rooted cuttings, with a

broad genetic base, could be produced for potential use in restoration.

Although this species has not been used in broad scale revegetation

projects in the Gondwana Link area, the species is commonly used in

amenity horticulture industry.

Most of the material sold in the market is clonal material, often

selected for particular desirable attributes (identical or from a narrow

genetic base), and thus not desirable for broad-scale restoration

projects. Selected cutting material (from stock mother plants) often

delivers better strike rates than cutting taken from wild material. In

2012 we were able to strike cuttings collected from numerous plants

(to ensure genetic diversity) in the south Stirlings to Gnowellan areas,

confirming that a commonly used amenity horticultural approach could

have merit for local restoration efforts.

In the summer of 2014, hundreds of A. cuneatus cuttings were

collected at sunrise from healthy populations and placed in cool eskys

for the 400km journey to a nursery in Perth WA. While it can be difficult

to get good strike rates from A. cuneatus, the strike rate of these

cuttings were very successful. These cuttings, which were originally

about 5 cm had grown into approximately 30cm plants by the time

they were planted at Yarrabee in winter 2014. Planted cuttings were

not irrigated and were essentially treated the same as any other

nursery raised seedling. They were then planted in the mentioned

failed rehabilitation area.

Following good rains during spring 2014, the Adenanthos cuneatus

had established themselves, and by the mid-summer of early 2015, the

plants were thriving in their new habitat (very few deaths). This initial

success has many people excited and this technique is currently being

upscaled to thousands of plants in current and future restoration

works.

The above process was duplicated in the Ranges Link area

(Porongurup- Stirlings) with similar encouraging results. Bare-rooted

cuttings were also planted at one Ranges Link site and high survival

has been achieved.

Juvenile Parthenium weed

ERADICATION OF PARTHENIUM WEED

Parthenium weed releases chemicals that inhibit the germination and growth of pasture grasses and other plants. It threatens the biodiversity in the Einasleigh Uplands bioregion and native grasslands in the central highlands of Queensland.

Description

Size

Parthenium weed is fast-maturing annual herb with a deep tap root and an erect stem that becomes woody with age. It usually grows to a height of 1 to 1.5 metres, but can reach a height of up to 2 metres.

Leaves

Its leaves are pale green, deeply lobed and covered with soft fine hairs.

Flowers

Parthenium weed has small creamy white flowers (four millimetres across) with five distinct corners. Flowers grow on the tips of the numerous stems.

Lifecycle

Parthenium weed can germinate, mature and set seed (up to 100,000 seeds per plant) in four weeks (DoE 2015). It generally germinates in spring and early summer, produces flowers and seed throughout its short life and dies in autumn (DoE 2015). However, with the right conditions parthenium weed can grow and produce flowers at any time of the year. Buried seeds can still germinate after eight to ten years (DoE 2015).

By Katina De Sousa

The declared pest parthenium weed (Parthenium hysterophorus) has been successfully eradicated from its only known presence in Western Australia following a four-year eradication program. The weed was originally detected at a road side near Karratha as part of a routine weed monitoring and control program. The eradication program incorporating quarterly inspections and application of pre-emergent herbicide resulted in the eradication of parthenium from this location, which has prevented significant ecological damage.

The Problem

Parthenium weed is a Weed of National Significance (WoNS) and a declared plant under Western Australian legislation, requiring active management to prevent environmental, social or economic impacts. It is regarded as one of the worst weeds in Australia due to its invasiveness, potential for spread and potential economic and environmental impacts (DoE 2015). Parthenium weed is an aggressive invader of disturbed land, perennial pastures and roadsides (DAFWA 2015a). It is very prevalent in drier parts of Queensland and New South Wales but absent in Western Australia apart from the one location in the Pilbara. It has a serious impact on the pastoral industry in Queensland, costing farmers and graziers over $22 million a year in reduced production and increased management costs (DoE 2015).

Parthenium weed can also cause some people to suffer severe allergic reactions. It can cause dermatitis, hay fever and asthma. It is also toxic to cattle and meat from livestock that eat the weed can be tainted (DoE 2015).

Growth Calendar for Parthenium Weed (from DoE 2015)

Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov DecFloweringSeed formationSeed dropPlant deathGermination

General growth patternGrowth pattern under suitable conditions


Parthenium weed flowers

Similar Species

Prior to late-flowering it can be mistaken for bishop’s weed (Ammi

majus) and hemlock (Conium maculatum) (NSW DPI 2015). After it has

set seed and becomes woody it can then be mistaken for fleabane

(Conyza spp.).

Habitat Distribution

Parthenium weed is capable of growing in most soil types but

becomes most dominant in alkaline, clay loam soils (DEEDI 2011). It is

best suited to areas with an annual summer rainfall greater than 500

millimetres. Based on climate suitability, it could potentially grow in all

mainland states and territories (DoE 2015).

Its large and persistent soil seedbank, fast germination rate and ability

to undergo dormancy make it well adapted to semi-arid environments.

Control

Preventing the spread of parthenium weed by utilising good hygiene

practices is the most cost-effective management strategy. The

Department of Agriculture and Food Western Australia recommends

the following herbicides for control of parthenium weed depending on

the life stage and location (DAFWA 2015b):

• Young, actively growing:

- Agricultural – 2,4-D; Picloram + 2,4-D amine; Glyphosate +

metsulfuron

- Roadsides and non-agricultural – Paraquat + diquat

• Seedlings and mature plants:

- Agricultural – Dicamba.

Timing of chemical control is critical. Parthenium weed should be

treated when plants are small and have not produced seed and when

grasses are actively growing to recolonise the infested area.

Plants should not be pulled up by hand, particularly if they have

already set seed as there is a danger that mature seeds will drop off

the plant and increase the area of infestation (DoE 2015). Parthenium

weed should not be touched with bare hands and a dust mask should

be worn if working near the weed for extended periods as it can cause

severe dermatitis and respiratory problems (NSW DPI 2015).

RESTORATION STANDARDS PROJECT LAUNCH

Upon completion of the Standards and Florabank review, it is intended

that work will turn to restoration plant stock quality /hygiene and

documenting best practice on ground works processes according to

particular habitat areas around the Nation.

RIAWA believes it important for members to be conversant with the

Standards and the associated issues going forward and to actively

participate in these processes and RIAWA is looking to upscale its

interaction with SERA accordingly and a launch event is being

planned.

Members should review the SERA Standards website and RIAWA will

keep you informed.

by David Hancock

National Standards for the Practice of Ecological Restoration in

Australia.

The Board of The Society for Ecological Restoration Australasia Inc.

(SERA) led by Professor Kingsley Dixon has achieved significant

progress with this groundbreaking project.

The Board has approved for release the National Restoration

Standards Draft for open review and comment.

http://www.seraustralasia.com/standards/contents.html

SERA and its community partners have worked to develop the

standards over the last 18 months for the purpose of:

• defining Restoration and other forms of environmental repair.

• documenting the principles that underpin Restoration.

• scheduling the planning and implementation issues necessary to

manage Restoration projects.

The document acknowledges the aspirational aspect of Ecological

Restoration but the SERA Board is also of the clear view that more

high level Restoration work will be essential in the future and that clear

direction on the subject, to guide practitioners and regulators is

appropriate and overdue. The Board sees the connectivity of science

to consultation to practice as a core issue that requires the attention of

all committed to improving the outcomes in both Restoration and

environmental repair generally.

Important also is the clear additional intention of this body of work to

drive higher standards in environmental repair more generally known

as revegetation / rehabilitation that may not qualify as Restoration

projects per se.

It should be noted that this project has already initiated a review of the

Florabank website now underway for best practice collection,

processing and storage of native seed for Restoration and that in the

future, the SERA Restoration standards will increasingly be referenced

within project specifications.

KIMBERLEY SEED BANK

A seed bank project in remote northern Australia is training Aboriginal

women in horticulture to help protect plant biodiversity of the region.

The importance of collecting seeds has become more urgent as

biodiversity in the Kimberley Biodiversity in region is under threat from

fires, feral animals and development. Nyul Nyul, Karajarri and Bardi

Jawi Oorany women ranger groups are being taught to collect, store,

and propagate culturally significant seeds and endangered plants.

Rangers will also learn to propagate plants at two on-country plant

nurseries and use them to regenerate the land.
