1.11.11.11.1 BackgroundBackgroundBackgroundBackground
Ace Nominees Pty Ltd has proposed to construct Red Hill Auditorium on Lot 2
Toodyay Road, Red Hill (Figure 1). The outdoor auditorium is designed to
accommodate up to 5,000 patrons. This design includes an acoustically treated stage,
car park, access road (and emergency egress) and 50 kl water tank. The auditorium
will hold up to 100 events over the warmer months (approximately 5 months per
year). Up to 20 events per year would be amplified. The site layout is illustrated in
Figure 2. 4.26 hectares of the 10.03 ha lot is proposed to be cleared, of which 0.86
ha will be revegetated with native species, post construction. The project design
places the infrastructure at the southern end of the lot, to avoid priority species and a
significant vegetation unit in the northern half of the site.
This project was granted state environmental approval by the Western Australian
Minister for Environment on 30 December 2004 with conditions described in
Ministerial Statement Number 673. Proponent Environmental Management
Commitment Number 1 requires the preparation of a Construction Environmental
Management Plan (CEMP).
1.21.21.21.2 PurposePurposePurposePurpose
This Construction Environmental Management Plan (CEMP) has been prepared to
satisfy Proponent Environmental Management Commitment Number 1 in Ministerial
Statement 673 (Appendix A). The scope of the CEMP includes:
Protection of flora and area of highest conservation value.
Weed and dieback management, including sourcing of imported soils from
die-back free areas.
Identifying areas to be disturbed and which will require rehabilitation.
Procedures for the direct transfer of topsoil from cleared to rehabilitated
areas.
Using only local native flora in the rehabilitation of disturbed areas and in
landscaping works.
Dust management.
Surface water runoff management.
Protection of Aboriginal heritage sites.

1.31.31.31.3 ObjectiveObjectiveObjectiveObjective
The overall objective of this CEMP is to:
Limit the offsite impacts due to construction activities.
1.41.41.41.4 AdviceAdviceAdviceAdvice
In accordance with Proponent Environmental Management Commitment Number 1 in
Ministerial Statement 673, the City of Swan and Department of Conservation and
Land Management (CALM) now the Department of Environment and Conservation
(DEC) were afforded the opportunity to provide advice on the CEMP.
The City of Swan and DEC were provided with Revision 1 of this CEMP (Final Rev 1)
for comment on 22 January 2010
Correspondence from the DEC is provided in full in Appendix B and comments
summarised below.
The DEC recognises that the site layout has been designed to avoid known
populations of the Priority 4 species Calothamnus rupestris.
The Management Plans provide adequate strategies in education during
construction, crowd control measures during events and placement if
remnant vegetation under a conservation covenant.
The contingency plan to revegetate with tube stock requires additional
advice from DEC is enacted (particularly concerning provenance species
and collection of propagation materials and seeds).
The 20 m setbacks proposed from the John Forrest National Park are
adequate.
The proposed boundary fence is adequate.
The control of entry points into John Forrest National Park is adequate.
Contingency measures for litter intrusion into John Forrest National Park
are adequate.
The City of Swan was also provided with a draft of this management plan on 22
January 2010 and not provided formal comments direct on the report to date. The
City of Swan has advised that further assessment of environmental management at
the site will occur during the Development Application and Building Licence local
government processes and it is during these processes that the City of Swan will
comment.

2.12.12.12.1 VegetationVegetationVegetationVegetation
There have been two flora surveys completed over the project area, in June 2000 and
November 2009. A total of 29 families, 68 genera and 112 plant taxa including
subspecies and varieties were identified. Only 1 weed species was recorded in the
site (Mattiske, 2000).
The vegetation complex that is within the proposed clearing area is classified as
‘Open Woodland of Eucalyptus marginata – Corymbia calophylla over heath species’
(Mattiske, 2000). This vegetation unit covers the majority of the lot. In the northern
part of the lot there is a small section of ‘heath over shallow exposed granite’
(Mattiske, 2000). This area is deemed significant for both flora and fauna as there are
only limited areas of this type of vegetation unit within the Darling Scarp. This area
should not be affected by the proposal as it is outside the proposed developmental
footprint (Mattiske, 2000) (Figure 3).
There has been no Declared Rare Flora (DRF), as defined under the Western
Australian Wildlife Conservation Act 1950 recorded on site.
One priority species has been found within the project site, Calothamnus rupestris
(priority 4) (Mattiske, 2009). Priority 4 species are classified as ‘taxa which are
considered to have been adequately surveyed and which, whilst being rare (in
Australia), are not currently threatened by any identifiable factors. These taxa require
monitoring every 5-10 years’ (DEC, 2007). This species was found in two locations
with a total of 11 specimens. Both of these locations are close to the granite outcrop
and hence outside the proposed development footprint.
There are no threatened ecological communities within the project area.
2.22.22.22.2 DiebackDiebackDiebackDieback
The project site is almost entirely infected with Phytophthora cinnamomi (a form of
dieback) with only the south east corner currently free. The root disease is caused by
a water-borne pathogen and is responsible for the death of a vast and diverse range
of plant species. This pathogen is readily dispersed by the movement of infected soil,
roots or water. It is also commonly linked to watercourses, tracks and roads where
rainfall exceeds 400 mm per annum and where human activity is frequent (Podger et
al, 1996).
2.32.32.32.3 LandscapeLandscapeLandscapeLandscape
The project area currently lies within the ‘resource’ zone under the City of Swan Town
Planning Scheme (Figure 4). The surrounding land is predominately uncleared
vegetation.
906 AC Construction Environmental Management Plan
Lot 2 Toodyay Road, Red Hill
Ace Nominees Pty Ltd
360 Environmental Pty Ltd 4
The adjourning lots are a clay quarry held by Midland Brick Company Pty Ltd.
To the east is the both the Red Hill Regional Landfill Site, operated by the East
Metropolitan Regional Council. To the north lies Toodyay Road and just beyond there
is a hard rock quarry and processing plant. Directly south is the John Forrest National
Park. The nearest residential dwelling is at least 2.2 km away. The land uses are
demonstrated in Figure 3.
The proposed infrastructure has been designed to reduce the impact on the priority
areas. All cleared areas are within a common type of vegetation of the darling scarp.
The access road has been placed to avoid the priority species and granite outcrops.
Large trees will not be cleared wherever possible. A buffer will be maintained between
Red Hill Auditorium and John Forest National Park.
2.42.42.42.4 Aboriginal HeritageAboriginal HeritageAboriginal HeritageAboriginal Heritage

3.13.13.13.1 Flora and Vegetation Flora and Vegetation Flora and Vegetation Flora and Vegetation
3.1.1 Protection of Priority Species and Significant
Vegetation Units
The site layout has been designed to avoid disturbance to populations of priority
flora and the significant vegetation unit ‘heath over shallow exposed granite’ in
particular the access road has been aligned to avoid these areas (Figure 2).
During construction the granite outcrop and locations of priority species will be
clearly marked and tagged. All staff and contractor inductions on site will include
details of the locations of Calothamnus rupestris and the preferred management
strategy (for example staff and contractors to avoid area).
In addition the clearing area will be limited onsite to those areas approved. The
approved areas will be clearly delineated on construction drawings and will be
marked onsite using tagging tape.
A series of contingency plans have been created in the event that priority flora is
degraded or damaged inadvertently. The area would be revegetated by seeding or
adding tubular stock. To prevent further damage from occurring while the area is
regrowing the entire area with priority species would be fenced.
3.1.2 Minimise Clearing
The approved management strategies for clearing are as follows:
Areas to be cleared will be clearly marked by signage and clearly
delineated on construction drawings.
No clearing is to occur without the site manager’s approval.
Clearing will be kept to a minimum at all times and never exceed the
defined clearing boundaries.
Staff will be inducted on site about approved areas to be cleared.
No vegetation clearing is to occur during high winds to reduce the
potential for dust emissions.
If an unapproved area is unintentionally cleared all the area will be
revegetated and rehabilitated with provenance correct, native species.
Significant vegetation will be clearly marked and access to these areas
will be prohibited.
906 AC Construction Environmental Management Plan
Lot 2 Toodyay Road, Red Hill
Ace Nominees Pty Ltd

360 Environmental Pty Ltd
Habitat trees will be marked prior to construction and retained where
practicably possible in the car park and stage areas.
3.1.3 Minimise Weed Populations
There is currently very few weeds species present and active management must be
undertaken to ensure this is not altered. Weed management is also very important
due to the presence of the adjacent John Forrest National Park.
To a large extent, management of weed hygiene shall work in conjunction with
dieback hygiene management measures to maximise effectiveness and minimise
costs. Specifically:
Top-soiled areas and known areas of weed infestation will be
communicated to all employees and contractors by signage and/or verbal
instruction.
Soils contaminated with weeds will not be used for stockpiling.
All machinery and equipment entering or leaving top-soiled or known
areas of weed infestation shall be cleaned of weed propagules by manual
brushdown or water.
Weeds that become established will be controlled, where necessary, by
an eradication program.
The services of a licensed weed control company may be utilised for
identification and control of weeds within the site.
Any cleared weed infested vegetation will be disposed of at the
appropriate landfill facilities.
All staff to be inducted on weed control measures such as identification
and awareness.
Where practicable, it will be encouraged that machinery is moved from
weed free areas to infested areas to prevent cross contamination.
No new weeds species will be introduced due to the construction
activities.
No spread of existing weed communities outside of the site.
3.1.4 Avoid Phytophthora Infection
Dieback controls will be in place to ensure the spread does not widen, these include:
Ensuring all material imported to site is die-back free. If sands, soils, fill,
mulch and tubestock are required these shall be confirmed as die-back
free.
Signposting or other form of demarcation to identify dieback status.
906 AC Construction Environmental Management Plan
Lot 2 Toodyay Road, Red Hill
Ace Nominees Pty Ltd
3
360 Environmental Pty Ltd
Clean down of equipment and machinery will be essential when moving
from a known infested site into an area of bushland known to be
uninfested, or where the status is unknown.
All vehicles must be clean when entering a dieback free site, however no
clean down is required to exit the site.
The minimum clean down standard will be the removal of all soil and plant
material. This shall be carried out by either brushing or water wash down.
If wash down is required, it will occur over a designated hardstand area
that is free of soil and material.
Topsoil from infested areas will, where possible, be used for rehabilitation
within other infested areas (taking limits on topsoil availability into
account).
Car park and access road will be sealed to reduce the risk of propagating
dieback.
All imported soils will come from die-back free areas.
Where practicable all work will be conducted during dry soil conditions
(November to April).
3.23.23.23.2 RehabilitationRehabilitationRehabilitationRehabilitation
Some areas of the site will be rehabilitated and landscaped post-construction.
Approximately 0.82 ha of the site are proposed for rehabilitation and are illustrated
in Figure 2. In summary rehabilitation will comprise:
Subsoil ripping and topsoil spreading
Pre-planting weed control (if required)
Planting of local tubestock and topsoil regeneration
Protection of tubestock with rabbit guards
Monitoring
Infill planting
The rehabilitation of the site is described further in the Rehabilitation Management
Plan (Appendix C).
A series of contingency plans have been created in the event that the populations of
priority flora or the significant vegetation community is degraded or damaged
inadvertently, including:
The areas would be revegetated by seeding or adding tubular stock. To
prevent further damage from occurring while the area is regrowing the
entire area with priority species would be fenced.
It is noted that should a revegetation contingencies be required,
consultation with DEC Threatened Flora officers be undertaken to

360 Environmental Pty Ltd
determine the most appropriate method of propagation. A Licence to Take
Flora under the Wildlife Conservation Act 1950 may be required to take
cuttings or seeds of protected flora.
3.33.33.33.3 Dust Management Dust Management Dust Management Dust Management
The dust generated by construction and deposited on adjacent native vegetation has
the potential to disrupt the photosynthetic, respiratory and/or water balance
processes of plants, thereby causing mortality or decreased health and increased
susceptibility to disease. Dust can also have impacts on air quality and human health
if not properly monitored.
The management strategies to reduce dust and the need for dust suppression
include:
Sealing both the car park and the access road.
Minimising vegetation clearing wherever possible.
No vegetation clearing is to occur during high winds to reduce the
potential for dust generation.
Vehicle access will be restricted and vehicles must remain on designated
access tracks and parking areas, at controlled vehicle speeds.
All soil stockpiles will be managed to reduce dust generation, including
applying hydromulch where necessary.
Compacted or cleared areas will be stabilised. Exposed surfaces such as
stockpiles and cleared areas, and the duration that these areas are
exposed, will be minimised.
Maintain general housekeeping practices to ensure there is no
accumulation of waste materials, within the construction area, that may
generate dust. Waste products that may generate fine dust particles (e.g.
concrete powder, stockpiled overburden) should be
contained/covered/relocated to prevent wind lift-off.
All staff to be inducted on dust control measures.
Where dust reduction is not possible dust suppression will occur by water spray.
3.43.43.43.4 Surface Surface Surface Surface Water Water Water Water Runoff Runoff Runoff Runoff ManagementManagementManagementManagement
Surface water from impermeable surfaces (stage area, carpark, access road,
backstage) will be allowed to gravity flow to specially installed collector drains and
directed to the onsite stormwater detention basins. The stormwater will be held in
the detention basins to allow solids to settle and litter to be trapped. Stormwater
will then be controlled-released into the minor, perennial watercourse located in the
north of the site parallel to Toodyay Road such as to maintain pre-development
flows (Figure 3).

Daily monitoring during construction will occur to ensure compliance with the CEMP
(Appendix D). Monitoring must also occur outside the clearance zone to ensure
there are no impacts outside the clearance zone.
Regular monitoring is necessary for dust control. If visible plumes of dust are being
generated and they are visible to off-site neighbours/community work must cease.
The site manager must be informed and approval must be granted before work
recommences.
After significant rainfall all drainage controls will be reviewed to ensure there is no
increased erosion and sediment control measures will be inspected to ensure they
remain effective.
Reporting procedures will be consistent with regulatory, local and development
requirements. Any non conformance and any adverse impacts will be reported on the
Site Hazard and Incident Form (Appendix E).
Any complaints or incidents to be reported immediately via the community
Complaints Register or incident report form (Appendix F).
Reportable incidents include:
Disturbance of habitat outside the construction area.
Accidental clearing outside the clearance area.

The success of the CEMP requires leadership to continuously promote best practice
environmental management and to make the people and resources available to
achieve the plan’s objectives. Management will ensure the continuing suitability,
adequacy and effectiveness of the CEMP by reviewing it at regular intervals
throughout the project. An important component of the overall site management is
the integration and communication of the requirements of this CEMP to the wider
workforce. The following process tools and management controls outline this
communication.

Hi Paul
Thank you for your feedback on the Vegetation and Landscape Features Protection Plan prepared for the proposed
Red Hill Auditorium (Lot 2 Toodyay Road, Red Hill).
I note in particular your comments regarding the contingency to revegetate with the P3 Flora species on the site
using provenance correct seeds and the need for a Licence. The report has been updated accordingly to require
advice from DEC should the contingency be enacted.
Further, I was wanting to clarify with you whether you comments were specific to the Vegetation and Landscape
Features Protection Plan or whether the comments were to cover both the Vegetation and Landscape Features
Protection Plan and the Construction Environmental Management Plan.
Are you able to please clarify?
Thanks
Toni

1.0 Background Rehabilitation will be directed towards the restoration of local biodiversity values on ground that has been disturbed during construction but which is not to form part of the operations of the auditorium. This would include batter slopes, edges of the access road, edges of the detention basins, surrounds of the operational area and tracks and firebreaks that are to be closed. The species to be chosen and the planting densities, should aim to match pre-excavation vegetation, adjoining vegetation, soil conditions and function of each site. The species will therefore need to be selected to match the local plant communities, or a restricted number of fast growing species may be used. Rehabilitation will contain Dieback and Weed Management in addition to monitoring and replanting failed areas. There will also be a completion criteria against which the revegetation should be compared. There are a number of management actions that can be taken in quarries to maximise rehabilitation effort and these will be used wherever possible. The general management actions are summarised below and will be used where applicable and as the opportunity presents. The site specific issues that relate to this site are also listed to explain how this site compares to the general rehabilitation guidelines. • All non required buildings, equipment and machinery will be removed from site. • Local education programs, and the involvement of site staff, should be undertaken to
increase on site ownership. • Save and directly transfer topsoil. • Overburden and interburden is to be removed and stored separate from topsoil. • Studies have shown that topsoil stripping and placement is best undertaken in summer
for maximum germination, but this raises the potential for additional dust generation from the fine humus particles.
• Topsoil will be spread at depths of 5 cm and should be spread during summer, preferably by the end of February.
• Vegetation clearing should be progressive and minimised to that required for each stage of excavation.
• Useful timber should be recovered for timber, fence posts and for firewood, subject to liabilities and site safety.
• Where possible vegetation should not be burned, however burning and mixing the ash with topsoil is beneficial to germination of local native seed.
• Seeds and other genetic material are to be collected if suitable onsite areas are available.
• Vegetation fragments and leaf litter are to be collected and directly transferred to rehabilitation areas.
• If direct transfer is not possible the vegetation is to be stored in low dumps to 1 metre high for later spreading.
• Compacted planting substrates should be deep ripped in two directions at 1 metre intervals.
• A minimum 400mm of overburden is to be spread over the surface where available. • Pre-seeding weed control may be required after any potential weed seeds have been
allowed to germinate. • Rehabilitation is to take place during the first winter months to minimise compaction
effects. • Local provenance seeds are to be collected from the site or purchased from commercial
seed collectors.
Rehabilitation Management Plan, Proposed Outdoor Auditorium Lot 2 Toodyay Road, Red Hill
Ace Nominees Pty Ltd Page 4
• A mixture of tube plants and seeding, combined with the direct transfer of topsoil, is normally the most effective where available.
• Seeding conducted in summer will need to use scarified leguminous seeds. • Seeding conducted in July to August will require the leguminous seeds to be heat treated
or scarified. • All seeds are to be smoke treated by soaking in “smoke water” for 1 day prior to seeding,
or dry smoked/mixed with charred sawdust. • A 10 g tree tablet or small handful of fertiliser beside each tube plant. • Rehabilitation will progressively follow construction with completed areas of the
excavation being revegetated as soon as practicable. • If completed correctly there should be no need for irrigation of revegetation in the south
west of Western Australia • Planting substrates should be left rough to encourage rainfall infiltration. • Erosion of sloping surfaces can be minimised by leaving the surface soft, rough and
undulating, with the undulations running along contour. • The final machinery run should be along contour and not down slope. • Wind erosion and the movement of sand grains can significantly impact on growth rates
unless controlled in susceptible areas. Remedial actions can include but not be limited to; fence wind breaks, spray mulching, cover crops, interim native vegetation or spreading mulch and vegetation.
• Rabbit guards or control may be required. • Completion criteria specifying the number of plants, species and structural form in a
given area are required. • Rehabilitation should be monitored at least annually to determine growth rates, any
factors impacting on revegetation and to compare against the completion criteria. • Steps to remedy deficiencies in rehabilitation should be taken during the next planting
period. • Monitoring and restoration should be undertaken for three years or until completion
criteria is achieved.

2.0 Rehabilitation Objectives The aim of the rehabilitation program is revegetation restoration of local biodiversity values on ground that has been disturbed during construction but which is not to form part of the operations of the auditorium. Revegetation activities will be integrated into the construction and land clearing process. The process of collecting local seed and the direct return of topsoils for use in rehabilitation will be pursued wherever possible in order to maintain vegetation provenance. Appropriate topsoil management is seen to be an important element in achieving successful rehabilitation and plant re-establishment on the restored surface.
Rehabilitation Management Plan, Proposed Outdoor Auditorium Lot 2 Toodyay Road, Red Hill
Ace Nominees Pty Ltd Page 6
3.0 Completion criteria
Rehabilitated construction and batter slopes
• Soil and slope stability. • A self sustaining cover of local native tree, shrub and groundcover species. • Provide at least one deep rooted tree or shrub per 3 m
2.
• Provide 1200 tree stems per hectare. • Provide a species richness of 10 species per 100 m
2.
• Provide an indigenous plant density of 100 per 100 m2.
• Weed species at levels not likely to threaten the native species Wet site areas and the edges of the detention basins
• A self sustaining cover of local native tree, shrub and groundcover species. • Maintenance of riparian shrubs and trees along watercourses and in wetter areas • Provide at least one deep rooted tree or shrub per 3 m
2.
• Provide 1200 tree stems per hectare. • Provide a species richness of 10 species per 100 m
2.
• Provide an indigenous plant density of 100 per 100 m2.
• Where reeds and rushes are solely used planting density for these species should be 4 plants per 1 m
2. Normally these will be planted between riparian shrubs in a
manner similar to local hills watercourses. • Weed species at levels not likely to threaten the native species
Depending on the success of rehabilitation, evolving community standards, and new research, the completion criteria may be adjusted to reflect emerging trends and also adjusted in terms of cover and species richness depending on the results achieved and emerging technologies or techniques.
Rehabilitation Management Plan, Proposed Outdoor Auditorium Lot 2 Toodyay Road, Red Hill
Ace Nominees Pty Ltd Page 7
4.0 Clearing and Earthworks
4.1 Vegetation Clearing 1. Vegetation clearing will be progressive and minimised to that required for each stage of
construction. 2. Useful timber will be taken for firewood, if feasible and subject to liabilities and site
safety. Consideration also needs to be given to the possibility that large fragments of vegetation may inhibit future use of the site. Alternatively, chipping of removed vegetation may be used.
3. Seeds and other genetic material will be collected from native vegetation if suitable
areas are available as sources. This will assist in the preservation of genetic material. 4. Where practicable vegetation will be directly transferred to a batter slope or other area
being rehabilitated. Smaller indigenous shrub material will be used in the rehabilitation process when available and suitable. Vegetation will be laid on re-formed slopes to reduce wind and water erosion as well as provide a source of seeds for revegetation. This is better than mulched vegetation which can swamp the germination of seeds.
5. If direct transfer is not possible the vegetation will be stored in low dumps to 1 metre high
or swapped with a nearby operator to try and ensure that the material is not wasted. 6. See the Dieback and Weed Management Plans.
4.2 Topsoil and Overburden Removal 1. Where possible topsoil and overburden will be directly transferred from an area being
cleared to an area to be rehabilitated. Topsoil from areas of native vegetation is a good source of local provenance genetic material and will be used wherever possible.
2. Overburden will be pushed to the perimeters of the construction for later use. 3. Construction will be worked progressively. 4. See the Dieback and Weed Management Plans.
Rehabilitation Management Plan, Proposed Outdoor Auditorium Lot 2 Toodyay Road, Red Hill
Ace Nominees Pty Ltd Page 8
5.0 Landform Reconstruction, Contouring and Revegetation
5.1 Soil Restoration 1. All buildings, equipment and machinery not required will be removed from site. 2. The final landform will be formed to the construction site specifications. 3. Areas to be revegetated will be deep ripped in two directions. The width between rip
lines will be 1 metre intervals. 4. Strategic stones and boulders will be retained in the native vegetation to increase
habitat. 5. A minimum of 300 mm of overburden will be spread over the surface where available to
provide a substrate for revegetation. Rehabilitation can be very successful with minimum overburden when the floor is adequately deep ripped.
6. Experience by Landform Research on rehabilitation on local quarry sites is that good
revegetation can be achieved by planting into soft overburden and deep ripped subsoils, if suitable local species are used.
7. See the Dieback and Weed Management Plans.
5.2 Pre-Planting/Seeding Weed Control Pre-seeding weed control is unlikely to be required because of a lack of weeds on site apart from Watsonia spp near the creekline at the northern edge of the site. If required, it will be conducted after overburden and topsoil have been spread and any seeds have been allowed to germinate. Broadscale weed treatment can be detrimental to the germination and growth of native species but may be required if the weed load is to be reduced. In May, after the first autumn rains, check for grass germination. Where grass has the potential to inhibit rehabilitation, such as areas to be returned to native vegetation, use a licensed contractor to spray with Fusillade or other suitable herbicide. 1. Any weeds likely to significantly impact on the rehabilitation will be sprayed with
Roundup or similar herbicide or grubbed out, depending on the species involved. The Weed Management Plan will form the basis of weed treatment. Depending on the nature of the planting substrate, a broad spectrum spraying program may be used. In areas where grass only is a potential problem, grass specific sprays will be used. In some areas where topsoil from cleared native vegetation is available no spraying may be required.
2. See the Weed Management Plan.
5.3 Revegetation 1. Ace Nominees will spread any vegetation, plus leaf, root and organic matter collected
from the land clearing procedures. This will increase the total organic carbon fraction, improving soil properties such as resistance to water and wind erosion and moisture
Rehabilitation Management Plan, Proposed Outdoor Auditorium Lot 2 Toodyay Road, Red Hill
Ace Nominees Pty Ltd Page 9
retention. The difference in properties between existing topsoil and subsoils is not considered a major impediment to rehabilitation of native species in the area.
2. Topsoil will be re-distributed in rehabilitated areas to depths of 50 mm where available.
Whilst burning is not always practicable the mixing of topsoil with ash and charcoal from burnt vegetation has shown a demonstrated improvement in the germination of local native species by triggering some species that do not normally germinate and by increasing germination rates. (Landform Research at Pickering Brook Gravel Quarry).
3. Topsoil provides a useful source of seed for rehabilitation when the correct handling of
the topsoil is used, stripped and replaced dry (autumn direct return). Maximum depth of 50 mm can be used to optimise revegetation of species-rich plant communities.
4. Studies have shown that topsoil stripping and placement is best undertaken in summer
for maximum germination, but this raises the potential for additional dust generation from the fine humus particles.
5. Topsoil will be spread directly from an area being cleared where possible, otherwise
reclaimed from a topsoil dump. 6. Topsoil will be spread during summer if possible, preferably by the end of February. 7. Rehabilitation will take place during the first winter months following the restoration earth
works. Leaving the completed earth works for one season will reduce the success of rehabilitation by at least 50%, due to compaction effects.
8. Local provenance seed will be collected from the site or purchased from commercial
seed collectors. Tube plants are also desirable because they reduce the risk of failure by providing a third method of establishment; • topsoil spreading • seed spreading • tube plants
A species list is attached.
9. A combination of the three methods is preferred by Ace Nominees (pers com Landform
Research) and has proven to be the most versatile and successful. The amount and species of additional seed and tube stock depends on the quality and seed store within the topsoil, and may vary from stage to stage.
10. Seeds of indigenous species will be scattered during late summer at the rate of
approximately 1 - 2 kg seeds per hectare if required. 11. Seeding conducted in summer will use scarified leguminous seeds that have been “dry
smoked”. Seeding conducted in July to August will have the leguminous seeds heat treated and all seeds will be smoke treated by soaking in “smoke water” for 24 hours prior to seeding. Alternatively dry mixing of the seeds with charred sawdust for up to 7 days has proved useful. (Pers com Landform Research).
12. Seed spreading will be achieved either using mechanical seed dispersal
equipment or using manual methods. Bulking with a spreading agent such as sawdust, vermiculite or sand is desirable.
13. Plant additional tube plants of local native species per hectare, at rates of 1 000 in June
in the areas of native vegetation, depending on the quality of the topsoil and its potential weed load.
14. Use a 10 g tree tablet or small handful of fertiliser beside each tube plant.
Rehabilitation Management Plan, Proposed Outdoor Auditorium Lot 2 Toodyay Road, Red Hill
Ace Nominees Pty Ltd Page 10
15. Rehabilitation will progressively follow completed areas of construction areas being as soon as practicable.
16. Tube plants will be installed with rabbit guards to prevent grazing by kangaroos. 17. Wetland restoration around the detention basins will consist of local native reeds and
rushes planted at the water edges and as filtration features. These will be planted densely at the rate of 4 per m
2.
5.4 Fertiliser 1. Fertiliser is not always required and will add nutrients to the ground water. If used a
fertiliser containing low nitrogen, phosphorous and potassium, and trace elements, is recommended to be spread at rates of up to 100 kg/hectare, applied to rehabilitation areas in the year of planting. Nitrogen is provided by using leguminous seed in the seed mix.
2. Further investigation will be used to determine suitable rates and the timing of
fertilisation. It may be possible to integrate seed dispersal and fertilisation into a single pass. The fertiliser will need to supply macro-nutrients, phosphorus, nitrogen and potassium, and other micro-nutrients.
5.5 Irrigation 1. Experience by Landform Research (pers com) in rehabilitation of quarries on the
Darling Scarp at Pickering Brook, Red Hill and Byford has shown that, when completed well, there is no need for irrigation of the rehabilitation.
2. Should there be a high mortality rate in germinated seedlings after the first year, due to
lack of water, the feasibility of providing irrigation will be investigated.
5.6 Erosion Control
1. Soil erosion occurs when soil is exposed and disturbed by wind or water,
although on this site wind is unlikely to be an issue. Erosion involves soil particles being detached from areas not adequately protected by vegetation, and moved down-slope.
2. The soils are loam/clay but runoff is normally minimal unless surface materials become
non-wetting. 3. Water erosion on the batter slopes can be avoided by the permeability of the materials
and by leaving the surface soft, rough and undulating, with the undulations running along contour. The final machinery run should be along contour and not down slope.
4. For rehabilitation areas, revegetation will take place as soon as possible following
landform and soil reconstruction. 5. Cleared vegetation will be transferred from an area being cleared, to protect against
erosion, assist with habitat creation and provide a seed source.
Rehabilitation Management Plan, Proposed Outdoor Auditorium Lot 2 Toodyay Road, Red Hill
Ace Nominees Pty Ltd Page 11
6.0 Monitoring 1. During late summer an assessment of the success of the rehabilitation will be made to
determine the rehabilitation requirements for the following winter. 2. Monitoring will include visual assessments and, where necessary, counts to determine
the success of the rehabilitation and restoration, as follows;
• plant density • plant growth • plant deaths • regeneration • weed infestation
3. As necessary steps will be taken to correct any deficiencies in the vegetation. 4. Rehabilitation of each stage will be monitored for a period of three years to ensure that
the revegetation meets the completion criteria of providing self sustaining indigenous shrub vegetation.
5. If rabbit damage is detected either place guards around the tube stock or bait using
commercial baits laid under low concrete slabs. Kangaroos are difficult to control other than by culling but this is not desired. Normally impact from kangaroos is regarded as acceptable damage.
6. Provide ongoing weed management to identify and treat significant environmental weeds
or weeds likely to impact on the rehabilitation. 7. Plants that have not survived are to be assessed to determine the number of
replacement plants required. To this is to be added the number of additional plants required to be installed in the following winter to bring any deficiencies up to the completion criteria.
8. In areas of rehabilitation that do not meet the completion criteria measures are to be
taken to increase the stem density to achieve the completion criteria. This could include but not be limited to;
• additional seeding • planting additional tube plants • additional use of fresh topsoil
