Executive Summary

This Rehabilitation and Vegetation Management Plan has been prepared to outline the proposed

rehabilitation and management of the proposed Public Open Space area in the southern portion of

Lot 102 Farrall Road, Midvale, as shown in the approved Farrall Road Local Structure Plan.

The objectives of the Rehabilitation and Vegetation Management Plan are to:

1. Revegetate an area of approximately 2,495 m2 that is in degraded condition with species associated with the FCT 20c using locally sourced genetic material where possible and undertake management to achieve a vegetation condition rating of ‘very good’ or better.

2. Undertake management of approximately 4,565 m2 of upland vegetation inclusive of 2,949 m2 of FCT 20c TEC vegetation to improve the condition of degraded portions to ‘very good’ or better.

3. Undertake management of FCT 11 vegetation within Bush Forever Site No. 309 to improve the condition of degraded portions to ‘good’ or better.

The proposed implementation schedule for the Rehabilitation and Vegetation Management Plan is

1 Introduction

Peet Stratton Pty Ltd proposes to develop Lot 102 Farrall Road Midvale, Western Australia (Lot 102)

for urban uses as part of the wider Movida residential development. Lot 102 contains Bush Forever

Site 309 (also referred to as the Farrall Road Bushland). In addition, Lot 102 contains remnants of the

native vegetation ‘floristic community type’ (FCT) 20c ‘eastern shrublands and woodlands’ in varying

condition (Gibson et al. 1994).

When present in good or better condition1, FCT 20c is a ‘threatened ecological community’ (TEC) that

is listed as ‘endangered’ under the Environment Protection and Biodiversity Conservation Act 1999

(EPBC Act) and ‘critically endangered’ by the WA Minister for the Environment. This TEC, which is

formally labelled ‘shrublands and woodlands of the eastern Swan Coastal Plain’, is hereafter referred

to as the ‘FCT 20c TEC’.

The Local Structure Plan (LSP) for Lot 102 was approved by the Western Australian Planning

Commission (WAPC) on 15 September 2016 (as part of the wider Movida estate). The LSP is provided

as Appendix A.

The LSP retains Bush Forever Site 309 and the majority of FCT 20c vegetation in good or better

condition within an area of POS within Lot 102. However, the LSP identified an area of approximately

800 m2 as an ‘area subject to further investigation’. While relatively small, this area has been

identified as being a remnant of FCT 20c vegetation in ‘good’ condition and therefore also

representative of the FCT 20c TEC. (Tauss & Associates 2016; Emerge Associates 2017)2. This area

requires additional consideration due to conservation significance of this TEC.

A LSP amendment is proposed which seeks the removal of the aforementioned ‘area subject to

further investigation’ containing the 800 m2 of FCT 20c vegetation. This ‘rehabilitation and vegetation

management plan’ (RVMP) has been prepared to support the LSP amendment over Lot 102 and to

enable the removal of the ‘area subject to further investigation’. Accordingly, this RVMP outlines

management commitments that are appropriate to offset the loss of the 800 m2 of FCT 20c TEC

vegetation (as well as all other areas of FCT 20c TEC vegetation that occur on the site1) and are

focused on management of the southern POS area within Lot 102. The requirements for, and the

preparation of, this RVMP has been informed by ongoing discussions with various stakeholders,

including the Department of Parks and Wildlife (DPaW), the Office of the Environmental Protection

Authority (OEPA), the City of Swan and the Department of Planning (DoP).

In addition, the RVMP has been prepared to support:

• a referral of a subdivision application for Lot 102 to the Environmental Protection Authority

(EPA) pursuant to Section 38 of the Environmental Protection Act 1986.

1 To represent a TEC, remnant vegetation is typically required to be present in ‘good’ or better condition (according to an established vegetation condition scale such as Keighery (1994). 2Tauss & Associates (2016) identified three additional small patches of FCT 20c vegetation within Lot 102 (totaling approximately 0.2 ha) and associated these with the FCT 20c TEC. For the purposes of this RVMP, only FCT 20c vegetation in ‘good’ or better condition was identified as the FCT 20c TEC.




• a referral of the proposed action (to implement residential development over the LSP area) to the Commonwealth Department of Environment and Energy (DoEE) pursuant to the EPBC Act.

• vesting of the public open space (POS) area that includes Bush Forever Site 309, remnant areas

of FCT 20c TEC and formal and active POS identified in the LSP over Lot 102 to relevant

management authority.

1.1 Site and planning context

Lot 102 is zoned ‘urban’ and ‘residential development’ under the Metropolitan Region Scheme (MRS)

and the City of Swan Local Planning Scheme (LPS) No. 17 respectively. As previously indicated the LSP

for the wider Movida estate was approved by the WAPC on 15 September 2016. A copy of the

approved ‘Farrall Road’ LSP is provided as Appendix A and the extent of Lot 102, the ‘area subject to

further investigation’ and the Farrall Road LSP layout is shown in Figure 1.

The portion of the LSP relevant to Lot 102 includes:

• residential lots

• the realignment of Farrall Road

• a reserve for POS in the northern most portion and southern third of Lot 102.

The southern POS area within Lot 102 was provided in the LSP to allow for the retention of Bush

Forever Site No. 309, a 50 m buffer to the eastern portion of Bush Forever Site 309 and the largest

identified patch of remnant FCT 20c vegetation in ‘good’ or better condition (representing the

FCT 20c TEC), as summarized in Emerge Associates (2017). This incorporates the area proposed for

rehabilitation and management (hereafter referred to as the ‘management area’) as shown in

Figure 1. The management area will also incorporate an area of formal and active POS to provide

open space and recreation facilities to members of the public.

The LSP approval noted that a ‘revegetation and vegetation management plan’ (RVMP) may be

required to be prepared and implemented as a condition of subdivision. As discussed above, this

RVMP has been prepared to support the LSP amendment to remove the ‘area subject to further

investigation’ and will be implemented as a condition of subdivision approval (associated with the

subdivision and development of the area adjacent to the management area).

1.2 Environmental context

A range of environmental investigations have been completed across the LSP area to date, including

specific fauna, flora and vegetation surveys. The results of these surveys, in addition to general

environmental information on Lot 102, is provided in the Environmental Assessment and

Management Strategy (EAMS) prepared by Emerge Associates to support the Farrall Road LSP. As

such, this document does not discuss general background environmental information but instead

focusses on site specific investigations relevant to Lot 102 and the management area.

Detailed site-specific flora and vegetation investigations over Lot 102 have been undertaken by a

number of parties, including Coffey Environments (2010), Emerge Associates (2015) and Tauss &

Associates (2016). Whilst plant community and vegetation condition mapping is generally consistent

between these investigations, there are some minor differences. In Emerge Associates (2017) these




differences were reviewed and the flora and vegetation assessment for Lot 102 was updated to

reflect new information. For the purposes of this RVMP, the two small patches of FCT 20c TEC

identified by Tauss & Associates (2016) have been accepted and included in consideration of offsets

associated with the LSP amendment.

The vegetation within Lot 102 is significant because it includes wetland vegetation (within Bush

Forever Site No. 309) and areas of vegetation identified as the FCT 20c TEC. The site contains one

larger patch (totaling approximately 0.3 ha) and two smaller patches (totaling approximately 0.2 ha)

of FCT 20c type vegetation within Lot 102 (as summarized in Emerge Associates 2017). In accordance

with the LSP, all wetland vegetation within Bush Forever Site No. 309 and the largest and best

condition patch of FCT 20c TEC vegetation to the east of the Bush Forever site will be retained within

the southern POS reserve (Figure 2).

The two small patches of FCT 20c TEC vegetation in ‘good’ condition outside of the management area

are proposed to be cleared. The remainder of remnant vegetation across Lot 102 primarily remains in

‘degraded’ to ‘completely degraded’ condition (Emerge Associates 2015); and therefore has limited

value for conservation. Some areas of vegetation identified as FCT 21c ‘Low lying Banksia attenuata

woodlands or shrublands’ by Emerge Associates (2015) and Tauss & Associates (2016) in the

northern portion of Lot 102 are also proposed to be removed. FCT 21c and FCT 20c contain a variety

of common flora species and vegetation proposed to be removed within Lot 102 provides a seed and

plant resource which can be utilised in the retained FCT 20c area, as detailed in this plan.

1.3 Stakeholder engagement

The following stakeholders were consulted on the preparation of this document:

• Department of Parks and Wildlife (DPaW)

• Department of Planning (DoP)

• Office of the Environmental Protection Authority (OEPA).

This involved an onsite meeting with the above parties at Lot 102 to discuss the RVMP on 22

November 2016.

A separate meeting was held on 16 February 2017 with the City of Swan to discuss the RVMP and the

LSP amendment.

These meetings did not reveal any areas of concern from stakeholders and all parties were generally

supportive of the content and intent of the RVMP.




2 Vegetation Management Area

The area of vegetation proposed for rehabilitation and management (the management area,

hereafter referred to as the site) comprises:

• wetland vegetation associated with Bush Forever Site 309

• remnant FCT 20c TEC vegetation

• disturbed areas with little or no native species present.

These areas are discussed in further detail below and shown in Figure 3.

2.1 Bush Forever Site 309

Bush Forever Site 309 (Farrall Road Bushland, Stratton) is located in the southern portion of Lot 102

(Figure 2). The attributes contributing to the regional significance of Bush Forever Site No. 309

include the representation of ecological communities and general criteria for the protection of

wetland, streamline and estuarine fringing and coastal vegetation (Government of Western Australia

2000a).

Bush Forever Site 309 contains a seasonal wetland community that was mapped as ‘woodland to low

open forest of Melaleuca preissiana, with emergent Corymbia calophylla over sparse shrubland of

Astartea scoparia, Marianthus sp., Xanthorrhoea preissii and Acacia pulchella over sedgeland to

closed sedgeland of Dielsia stenostachya and Cyperaceae sp. and open forbland of Corynotheca

micrantha subsp. micrantha, Drosera spp. and Burchardia congesta (Emerge Associates 2015). No

floristics quadrats were sampled within this vegetation, but based on its structure and composition it

is inferred to represent FCT 11 ‘wet forests and woodlands’ (Gibson et al. 1994). FCT 11 is a relatively

well reserved wetland plant community across the Swan Coastal Plain (Gibson et al. 1994).

The remnant native vegetation in this area is mostly intact and was mapped as being in ‘excellent’

condition in accordance with the Keighery (1994) vegetation condition scale (Emerge Associates

2015) (Plate 1). However, some degraded areas occur around the margins where understorey layers

are replaced by a closed grassland of *2Ehrharta calycina (perennial; veldt grass), Ehrharta longifolia

(annual veldt grass), Eragrostis curvula (African love grass) with localised occurrence of the bulb

*Watsonia meriana var. bulbillifera (bugle lily). The definitions used in the Keighery (1994)

vegetation condition scale are provided in Table 1.

2 * denotes species not native to Western Australia.




Table 1: Keighery (1994) vegetation condition scale

Condition category Definition (Keighery 1994)

Pristine Pristine or nearly so, no obvious signs of disturbance.

Excellent Vegetation structure intact, disturbance affecting individual species and weeds are non-aggressive species.

Very good Vegetation structure altered obvious signs of disturbance. For example, disturbance to vegetation structure caused by repeated fires, the presence of some more aggressive weeds, dieback, logging and grazing

Good Vegetation structure significantly altered by very obvious signs of multiple disturbances. Retains basic vegetation structure or ability to regenerate it. For example, disturbance to vegetation structure caused by very frequent fires, the presence of some very aggressive weeds at high density, partial clearing, dieback and grazing.

Degraded Basic vegetation structure severely impacted by disturbance. Scope for regeneration but not to a state approaching good condition without intensive management. For example, disturbance to vegetation structure caused by very frequent fires, the presence of very aggressive weeds, partial clearing, dieback and grazing.

Completely degraded The structure of the vegetation is no longer intact and the area is completely or almost completely without native species. These areas are often described as ‘parkland cleared’ with the flora comprising weed or crop species with isolated native trees or shrubs.

The part of the site that includes Bush Forever Site 309 is mapped as part of a ‘multiple use’ wetland

(Figure 2) but due to the generally excellent condition of vegetation present ( Plate 1) it is considered

to be more representative of a ‘conservation category’ wetland (Emerge Associates 2015).

Plate 1: Vegetation in 'excellent' condition within Bush Forever Site 309.




2.2 Remnant FCT 20c vegetation

The vegetation determined to represent FCT 20c was mapped as a ‘sparse to open woodland of

Banksia attenuata, Banksia menziesii and Eucalyptus todtiana over open shrubland to shrubland of

Adenanthos cygnorum and Allocasuarina humilis over low sparse shrubland to shrubland of

Conostephium pendulum, Stirlingia latifolia and Hibbertia spp. over forb and sedgeland of Lyginia

spp., Dasypogon bromeliifolius, Conostylis aculeata, Podotheca gnaphalioides and forb/grassland of

pasture weeds’ (Emerge Associates 2015).

Floristic quadrats sampled by both (Tauss & Associates 2016) and Emerge (2016) determined the

community to represent FCT 20c. This community is known to occur 700 m east of the site within the

Talbot Nature Reserve.

Plate 2: FCT 20c vegetation in ‘very good’ condition adjacent to Bush Forever Site 309 on the eastern side of the site.

The condition of remnant FCT 20c vegetation within the Lot 102 ranges from ‘very good’ to

‘completely degraded’ (Plate 2). The better condition FCT 20c vegetation is located within the centre

of remnant vegetation to the east of the Bush Forever site (Figure 2). The remaining areas of FCT 20c

TEC vegetation to the south and north of the Lot 102 are present in ‘degraded’ and intermediate

‘good to degraded’ condition and include *Ehrharta calycina (perennial veldt grass) in particular at

varying densities and cover (Plate 3).

As previously outlined, the FCT 20c vegetation in ‘good’ or ‘very good’ condition is representative of

the FCT 20c TEC. This TEC is listed as ‘endangered’ under the Environment Protection and

Biodiversity Conservation Act 1999 (EPBC Act) and ‘critically endangered’ by the WA Minister for the

Environment. The condition of FCT 20c vegetation within the management area ranges in condition

from ‘degraded’ to ‘very good’ and so with management the extent of the FCT 20c TEC within the

site may be increased.




Plate 3: FCT 20c vegetation in showing the presence of veldt grass.

2.3 Disturbed areas with little or no native species present

Parts of the site have been disturbed and now contain areas of vegetation in ‘completely degraded’

condition (Plate 4). Some of these areas comprise completely cleared tracks which have been

historically used for access across the site (Plate 5). Few native flora species remain in these areas,

although the native annual herb Podotheca gnaphalioides may be present. The aggressive weed

perennial veldt grass is dominant in most degraded and completely degraded locations.

3 Objectives

3.1 Rehabilitation goals

The primary goal of the RVMP is to rehabilitate vegetation within the site to offset clearing of FCT

20c TEC within Lot 102, in addition to protecting and managing wetland vegetation within Bush

Forever Site 309.

Where vegetation is already present in ‘very good’ condition, rehabilitation may only require that

careful weed control is undertaken. For areas that are present in ‘degraded’ or ‘completely

degraded’ condition more intensive management, including revegetation and weed control, will be

required to rehabilitate FCT 20c and wetland vegetation.

The RVMP will aim to improve the condition of degraded areas of FCT 20c vegetation as generally

identified by DPaW (Appendix B) to ‘very good’ condition. In addition, the condition of other

‘degraded’ and ‘completely degraded’ areas of FCT 20c and FCT 11 wetland vegetation within the

management area will be managed to at least ‘good’ condition.

Additionally, the following general restoration goals are nominated:

• Where possible local provenance biological material will be used in rehabilitation areas. Where

local material cannot be sourced, material from the nearby Swan Coastal Plain may be

included. All material brought o site should be certified dieback free.

• No negative impacts should occur to adjacent remnant vegetation or other components onsite as a result of rehabilitation works.

3.2 Target ecosystems

3.2.1 FCT 20c - Shrublands and woodlands of the eastern Swan Coastal Plain

The ‘shrublands and woodlands of the eastern Swan Coastal Plain’ TEC was defined based upon

FCT 20c, as determined in the Gibson et al. (1994) regional floristic assessment of the southern Swan

Coastal Plain. This community occurs mainly on the transitional Forrestfield unit and soils of the

Ridge Hill Shelf, on the Swan Coastal Plain adjacent to the Darling Scarp, but also extends marginally

onto the alluvial clays deposited on the eastern fringe of the Swan Coastal Plain. The community

reflects this transitional landform and soil zone between the Scarp and the Swan Coastal Plain, with

many species present being more common on the Scarp and others more commonly associated with

marri - wandoo woodlands on heavy soils (English and Blyth 2000).

FCT 20c occurs as a shrubland, or woodland, of Banksia attenuata and Banksia menziesii, sometimes

with Allocasuarina fraseriana, over diverse shrub and herb layers (DotE 2016). The shrub layer

usually includes Adenanthos cygnorum, Hibbertia huegelii, Allocasuarina humilis, Bossiaea eriocarpa,

Hibbertia hypericoides and Stirlingia latifolia. Common herbs include Conostylis aurea, Trachymene

pilosa, Lomandra hermaphrodita, Burchardia umbellata and Patersonia occidentalis. Common sedge

species include Mesomelaena pseudostygia and Lyginia barbata (English and Blyth 2000).




3.2.2 FCT 11 – Wet forests and woodlands

FCT 11 ‘wet forests and woodlands’ is associated with riparian and wetland areas throughout the

Swan coastal plain. This community is typically structured as a low closed forest or woodland. It

includes many commonly occurring wetland species such as Eucalyptus rudis, Melaleuca preissiana,

Astartea fascicularis, Lepidosperma longitudinale and *Cotula coronopifolia.

3.2.3 Reference sites

To ensure that the rehabilitation areas are effective in restoring the specific vegetation that is

present within the site, reference information will first be derived from previous flora and vegetation

surveys within the site (Emerge Associates 2015; Tauss & Associates 2016). In addition to

information derived in situ, understanding of the target ecosystems is provided by regional floristic

surveys like Gibson et al. (1994) and Keighery et al. (1996).

The occurrence of FCT 20c community is likely to have been rare prior to extensive clearing of the

Forrestfield geomorphological unit (Gibson et al. 1994). Based on the interim recovery plan for the

community (English and Blyth 2000) (DEC 2006), only two significant known occurrences of FCT 20c

remain. One of these is the Talbot Road Bushland, located approximately 700 m to the east of the

site, and the other is the Bushmead Rifle Range in Helena Valley, approximately 4.5 km south of the

site. These bushland areas therefore provide the most appropriate reference sites for FCT 20c. A

total of 9 quadrats for FCT 20c were sampled in Gibson et al. (1994), although these are mostly

located within the Talbot Road Bushland.

FCT 11 is more widely distributed and there are 13 quadrats for FCT 11 in Gibson et al. (1994).

3.3 Rehabilitation objectives

Based on the goals and targets outlined above, the following objectives are specified for this RVMP:

1. Revegetate an area of approximately 2,495 m2 that is in ‘degraded’ condition with species associated with the FCT 20c, using locally sourced genetic material where possible and undertake management to achieve a vegetation condition rating of ‘good’ or better.

2. Undertake management of approximately 4,565 m2 of upland vegetation inclusive of 2,949 m2 of FCT 20c TEC vegetation to improve the condition of ‘degraded’ and ‘good’ portions to ‘very good’ or better.

3. Undertake management of FCT 11 vegetation within Bush Forever Site No. 309 to improve the condition of ‘degraded’ portions to ‘good’ or better.

The extent of the management area and individual management zones is illustrated in Figure 3 and

vegetation condition is defined using the Keighery (1994) scale as outlined in Table 1.




4 Methods

4.1 Rationale

Five discrete areas (herein referred to as management zones) are defined to allow targeted

rehabilitation of areas of FCT 20c and Bush Forever Site 309, as shown in Figure 3. These areas are

classified based on whether management or both revegetation and management will be undertaken

as shown in Table 2. The landscape plan detailing management zones and landscaping features is

shown in Appendix C.

Table 2: Management zones and approaches

The primary issue requiring management within remnant FCT 20c areas is disturbance and weed

invasion. Management of existing areas of the FCT 20c TEC requires that careful weed control and

refuse removal is undertaken. Grass weeds are the primary issue including *Erharta calycina

(perennial veldt grass). Therefore, grass selective herbicide application will be a suitable

management option, along with manual weed control techniques if practical.

The primary issue requiring management within Bush Forever Site 309 is also disturbance and weed

invasion. Because the vegetation is in ‘excellent’ condition, planting or other revegetation activities

would only be recommended in more degraded parts and only once weed control has been

undertaken. For this reason, and the fact that propagules of dominant understory species such as

Dielsia stenostachya may be difficult source, no revegetation has been prescribed. Grass and bulbous

weed species are dominant within parts of this area, so the application of selective herbicides will be

a suitable management option. Broad spectrum herbicides may be applied where native cover is low

and manual weed control techniques may also be applied if practical. In addition, this part of the site

contains piles of refuse which will be removed once the site is secured.

Two classes of revegetation have been defined to ensure that the management intensity and

techniques consider existing values. The infill area includes degraded areas of FCT 20c that have




lower native understory density and cover, but include canopy or larger shrub layer species like

Banksia attenuata, B. menziesii, Adenanthos cygnorum and Allocasuarina fraseriana. In these areas

infill planting using tubestock will focus on increasing understory diversity and cover.

The intensive revegetation management zone currently contains few native species and has a high

cover of perennial veldt grass and other weeds. In these areas techniques like broad spectrum

herbicide application, scalping, translocation, direct seeding and tubestock planting can be applied

without risking significant damage to existing native vegetation.

The two small patches of FCT 20c and other isolated and degraded patches of FCT 20c and FCT 21c

vegetation across Lot 102, provide an opportunity to salvage material for use in the intensive

revegetation management zone. Two methods of translocation will be considered including ‘direct

vegetation transfer’ and translocation of Macrozamia fraseri (zamia palm). Direct vegetation transfer

requires that small sections of vegetation including small shrubs, herbs and sedge components,

complete with soil surrounding their root zones, are relocated using a loader or other machinery.

Some of the larger native plants will not survive being disturbed and moved. However, it is likely that

a proportion will survive and, moreover, the seed and below ground storage organs of many species

will be transferred, along with associated invertebrate, microbial and mycorrhizal (fungi)

components. Because of the wide variety of organisms that may be relocated, direct vegetation

transfer can result in superior restoration outcomes than could be achieved by planting and seeding

alone.

In conjunction with the rehabilitation it is expected a number of zamia palms present within parts of

Lot 102 will be salvaged. These palms will primarily be used within the formal POS area adjacent to

BF 309, but may also potentially be used for other POS areas within the LSP area.

In total 1.58 ha of wetland vegetation and 0.46 ha of FCT 20c vegetation will be rehabilitated through

management and 0.25 ha of FCT 20c vegetation will be rehabilitated through revegetation and

management.

4.2 Licenses and approvals

The requirements for translocation permits will be discussed with DPaW prior to the commencement

of any such activity. However, such permits may not be required given the plants will not be removed

offsite.

Similarly, a ‘licence to take’ would be required prior to any such activity including seed collection.

4.3 Landform preparation

4.3.1 Weed control

Depending on techniques employed, weed control may be required to prepare revegetation areas

prior to planting or seeding. Where weed cover is higher, a broad spectrum herbicide formulation,

such as Roundup© (glyphosate 360g/L), may be applied to achieve blanket control. However, as

outlined in Section 4.5, in many parts of the site spot spraying, selective herbicide or manual

methods may be necessary to minimise the risk of off target impact to existing native vegetation.




4.3.2 Scalping

Scalping involves the removal of the upper layer of soil profile where the below ground parts of

perennial weeds and weed seed are stored. Scalping is particularly effective technique for controlling

certain perennial grasses and may be a good option for preparing the areas of intensive revegetation.

4.3.3 Excavation of voids to facilitate translocation

Where translocation is planned (refer Section 4.4.1) soil should be excavated to a depth of

approximately 400 mm to create a void within which FCT 20c material and soil, or zamia palms, can

be placed.

4.3.4 Topsoil / mulch application

If practical topsoil may be harvested from parts of Lot 102 with higher native species cover and

respread in revegetation areas. Many native species that cannot be easily sourced as seed or

propagules may be established from the seed and other material stored within topsoil. Due to the

degraded condition of vegetation within much of Lot 102 it is unavoidable some weed seed will be

transported in topsoil. But nonetheless care will be taken to avoid taking topsoil from areas of high

weed cover.

4.4 Plant establishment

4.4.1 Translocation

Direct vegetation transfer requires that small sections of vegetation including small shrubs, herbs

and sedge components, complete with soil surrounding their root zones, are relocated using a loader

or other machinery. The sections of vegetation and soil are then placed in pre-prepared void as

carefully as possible (refer Section 4.3.3). If this process is progressed, the vegetation will be moved

in early winter when temperatures are cooler and seasonally higher rainfall occurs, but prior to the

germination of annual and geophytic native species. If the transfer of vegetation does not coincide

with natural rainfall supplementary water may be applied to assist in bedding down the transferred

material.

The translocation of zamia palms is expected to occur predominantly into the formal POS area. It is

recommended that the zamia palms are removed by a specialist contractor who is expected to take

the plants off site for hardening off in a nursery setting prior to returning them for installation as part

of landscaping works. Supplementary water is likely to be required for a number of years to assist the

zamia palms to establish.




4.4.2 Sourcing tubestock

Tubestock should be sourced from an accredited nursery and grown from local provenance seed or

cuttings with genetic diversity. Where possible seed and cuttings collected within Lot 102 will be

used to propagate tubestock. But where a shortfall exists for important species or the required

quantities seed or cutting material may be sourced from nearby parts of the Swan Coastal Plain or

Darling Scarp.

The tubestock should be grown as tall as possible to facilitate deep planting as outlined in

Section 4.3.3. Nursery staff can advise which species can be grown tall enough such that deep

planting is appropriate. Before collection, the tubestock should be hardened off and in good

condition.

A list of 22 species suitable for use in the FCT 20c revegetation areas, and recommended tubestock

numbers, is provided in Table 3. This species list is constructed from observations of FCT 20c

vegetation on site, combined with species known to be present within FCT 20c. The revegetation

contractor may substitute some recommended species with another appropriate local native species

that occurs within FCT 20c due to availability of seeds and/or tubestock.

Plant numbers have been calculated based a target density of two (2) plants per m2 after three years,

assuming a 70% annual survival rate. Note that this target relates to tubestock derived plants only

and actual plant density is expected to be higher due to the presence of remnant vegetation and the

application of complementary topsoil, translocation and direct seeding revegetation techniques.

Increasing initial planting density to accommodate for expected plant mortality was incorporated to

reduce the requirement for future infill planting. As a general rule a 70% survival rate can be

expected for most native plants in the first few years after planting, without supplementary water or

maintenance, if they are installed correctly and early in the growing season. However, plant survival

will also vary from year to year in response to differences in seasonal conditions and potential

interference by other factors such as predation or disturbance.

4.4.3 Installing tubestock

Tubestock should be installed using a deep planting method. For example, tubestock grown to

300 mm tall can be planted with only 50-75 mm of stem showing above the sand surface (WAPC

2003). This positions the roots much closer to water supplies and decreases water loss in hot

conditions. Deep planting can also help to prevent herbivory from resulting in the death of seedlings,

which can easily re-sprout if the top of the plant is removed.

Note installing tree bags / guards is not recommended as these increase installation time and require

removal once plants are established.

4.4.4 Direct seeding

If sufficient seed material can be obtained direct seeding of selected native species may also be

conducted. Seeding lists can be determined following completion of seed collection program. Key

species for which seeding would be beneficial may include components of shrub layer that are




known to germinate well from seed such as Acacia spp., Allocasuarina spp., Eremaea pauciflora and

Melaleuca spp. and annual herbs such as Podotheca gnaphalioides.

4.5 Weed management

Weed control will be required to reduce weed cover within the management area. Weed control

may also be required prior to planting in revegetation areas to prepare the site and reduce

competition with establishing native plants. Following revegetation weed control will then be

required in late winter or spring 2017 to remove weeds that have established with translocated

material and/or after planting. The weed control treatments will then need to be repeated in

subsequent years to reduce competition with establishing native plants and achieve weed cover

targets. It is likely that weed control will need to be carried out at least once a year until handover in

Year 4. Weed management should be guided by monitoring inspections as outlined in Section 5.1.

The most appropriate method to control weeds should be decided after annual site inspection has

been completed. But may include both chemical (herbicide) and manual (hand weeding) based

approaches as outlined below.

To ensure weeds are not spread within the site or to other sites, the following management

measures should be undertaken during restoration works:

• Topsoil from areas with high weed cover should be buried at depth and not re-used in

restoration areas.

• Topsoil from areas with low weed cover should be stockpiled in relatively weed free location

for latter reuse in restoration areas (if not already salvaged for translocation).

• If required, imported fill or mulch material should be certified free of environmental weeds.

4.5.1 Herbicide application

For grass weeds a grass selective formulation such as Fusilade® Forte (13 ml/L or 6.5 L/ha) may be

applied, without risking off target impact to most of the native species present. The best time to

apply grass selective herbicide to control perennial veldt grass is between July and August (DPaW

2016a). Note that native grass species such as Microlaena stipoides are present within Bush Forever

Site 309 and Neurachne alopecuroidea and Austrostipa spp. are present within remnant FCT 20c

vegetation. Other native flora may also be sensitive to particular selective herbicide formulations.

Therefore, herbicide application should be targeted to areas of higher weed cover and should be

undertaken with caution to avoid off target impacts.

For bulbous weeds, a selective formulation such as 2,2-DPA 10 g/L + Pulse® may be applied. The best

time to apply bulb selective herbicide to control Watsonia meriana is September as plants are

flowering (DPaW 2016b).

Where weed cover is higher a broad spectrum herbicide formulation such as Roundup© (glyphosate

360g/L) may be applied as a blanket spray over larger area or as a spot spray that carefully targets

specific weed plants amongst native vegetation.

Note herbicides should only be applied by a licenced pesticide management technician and in

accordance with manufacturer’s instructions as provided on product label. A licenced pesticide




management technician will be able to advise what a suitable approach would be based on

information obtained during a site inspection.

4.5.2 Hand weeding

Alternatively, hand weeding can be successful for certain species and where weeds are present with

relatively low abundance. Different techniques may be appropriate for different weed species and

technical reference should be consulted where required to ensure manual control is as effective as

possible.

4.6 Access management

Generally, public access to the revegetation areas will be restricted to increase the success rate of

the program, which will be achieved through the implementation of various measures discussed

below.

4.6.1 Fencing

Fencing will be erected around the revegetation and management areas (both sides of any paths) to

restrict access. Gate(s) for maintenance access will be provided based on agreement with the City of

Swan. The fencing specification will be determined in consultation with the future land manager for

the site.

Fencing on the western boundary of the management area (generally aligning with the Bush Forever

site boundary) has already been constructed following approval from the City of Swan. Fencing in

this location is in accordance with the City of Swan ‘Chain Link Fence and Gate Detail’ (Drawing STD

58-3s Amendment A).

4.6.2 Paths

Access to the site will be managed via formal paths. The design of paths is yet to be finalised, but it is

expected they will be constructed from compacted inert material or appropriate form of hardstand

subject to approval from the City of Swan. Paths will be located within existing firebreaks. Sealed

paths form hard edge interfaces to management and rehabilitation areas and help reduce weed or

turf encroachment.

4.6.3 Signage

Signage may be erected to identify rehabilitation areas, which could involve educational material

regarding the environmental value of the vegetation. This would involve consultation with the City of

Swan.

4.7 Dieback management

The soil borne water mould Phytophthora cinnamomi (dieback) occurs in the surrounding area and

may occur or have occurred previously within the site. Dieback kills susceptible plants by attacking

their root system which inhibits uptake of water and nutrients (DPaW 2015). A large range of native

species are susceptible to dieback which is spread through movement of soil and mud, especially by




vehicles and footwear. There is no practical large-scale cure for dieback and therefore containment is

the primary option available for management.

To ensure dieback is not spread within the site and to other sites, the following management

measures should be undertaken during rehabiliation works:

• Vehicles, tools, equipment and machinery should be free of all mud, soil and plant material on

arrival at the site. It is recommend that vehicles, tools, equipment and machinery are

thoroughly cleaned with a high pressure hose and disinfected with bleach or fungicide product

such as Phytoclean©, at an appropriate wash-down location.

• If vehicles, tools, equipment and machinery are temporarily removed from the site during

works they must be free of all mud, soil and plant material on return.

• If required, imported fill or mulch material should be certified free of dieback.




5 Monitoring

Monitoring is required to enable the evaluation of the outcomes of revegetation and management.

The management area is proposed to be inspected a minimum of two times per year. One inspection

will occur in early autumn (March) to inspect revegetation areas and determine plant establishment

rates. The second inspection will occur in early winter (June) to inspect all management areas and

inform the upcoming weed control program. Inspections will be completed either by the

revegetation contractor or the project environmental consultant.

5.1 Revegetation area inspections

Revegetation should be inspected by foot and as far as necessary the entirety of each revegetation

area traversed. Vegetation condition should be assessed by collecting an inventory of native species

present along with measurements and mapping of native plant density and weed cover. Areas of

low native species establishment should be identified for contingency action and photographs taken

of significant features, including plant recruitment or losses. Weed assessments should involve

identification of priority weeds for management. A map showing areas that require further actions

such as planting of weed management will be produced as part of the inspection.

5.1.1 Vegetation condition assessment

Assessing vegetation condition is traditionally a qualitative exercise. This presents problems for using

vegetation condition to evaluate rehabilitation success due to the potential for different outcomes

between assessors. The Keighery (1994) vegetation condition scale is a categorical scheme that is

commonly applied on the Swan Coastal Plain. Applying the Keighery (1994) scale ‘very good’

condition vegetation can have a structure that appears altered, with obvious signs of disturbance and

may include some more aggressive weeds. Whereas ‘good’ condition vegetation can be significantly

altered and include very aggressive weeds and partially cleared areas, while retaining at least a basic

structure or the ability to regenerate it. Based on Keighery (1994) ‘very good’ condition generally

implies vegetation has a relatively intact structure and composition, while ‘good’ condition implies

that vegetation has average intactness, intermediate between being relatively intact and degraded.

Casson et al. (2009) aligned the Keighery (1994) vegetation condition scale with additional

quantitative parameters. Using the Casson et al. (2009) scale, parameters relate to the structure,

composition, level of disturbance and/or weeds and native plant recruitment are also assessed. For

example, ‘very good’ condition vegetation would be expected to have all structural layers present

with minor modification, most flora species recorded within reference sites, a moderate to low level

of ground disturbance and weed presence; and several flora species that demonstrate recruitment

through the presence of seedlings or saplings. Whereas good condition vegetation would be

expected to retain all expected structural layers but with discontinuous areas, diminished species

presence, moderate levels of disturbance and only isolated recruitment by a limited selection of

species (Casson et al. 2009).

Recent advice from the DoEE (2016) on the banksia woodland of the Swan Coastal Plain TEC, has

further aligned the Keighery (1994) vegetation condition scales with quantifiable parameters for

native species diversity and weed cover.




The evaluation criteria for vegetation condition defined in this RVMP were adapted from the DoEE

(2016) scheme, with reference to definitions in Keighery (1994) and Casson et al. (2009). In this

RVMP criteria for native species diversity were further quantified by requiring that relative native

diversity is calculated as a percentage of the mean species richness recorded from reference sites

(Gibson et al. 1994), as outlined in Table 4. These criteria should be applied by mapping the native

species and weed cover over the extent of revegetation areas, including areas of low native or high

weed cover.

Table 4: Recommended vegetation condition scale based on Keighery (1994) and DoEE (2016).

Good Vegetation structure significantly altered by very obvious signs of multiple disturbances. Retains basic vegetation structure or ability to regenerate it. For example, disturbance to vegetation structure caused by very frequent fires, the presence of some very aggressive weeds at high density, partial clearing, dieback and grazing.

Moderate native plant species diversity

5-50% 20-50%

Degraded Basic vegetation structure severely impacted by disturbance. Scope for regeneration but not to a state approaching good condition without intensive management. For example, disturbance to vegetation structure caused by very frequent fires, the presence of very aggressive weeds, partial clearing, dieback and grazing.

Low native plant species diversity

20-70% <20%

Completely degraded

The structure of the vegetation is no longer intact and the area is completely or almost completely without native species. These areas are often described as ‘parkland cleared’ with the flora comprising weed or crop species with isolated native trees or shrubs.

Very low native plant species diversity

Greater than 70%

<20%

1Relative to expected natural range of diversity for that vegetation unit such as a ‘floristic community type’ (FCT) defined by

(Gibson et al. 1994).




5.1.2 Native plant density measurement

A measure of native plant density will be obtained from a minimum of three randomly located

samples within each management zone. Sample units may include suitably scaled quadrat (e.g. 25 m2

for tree layer or 4 m2 for shrub layer) or line intercept or other appropriate method (such as direct

counts for tree layer). Smaller sample units may be recorded with a digital photograph (facing the

ground). The location and data from each sample will be provided in the final report (refer Section

5.4).

5.1.3 Photo-point monitoring

Photo-points will be established to assist in cataloguing the progress of revegetation areas. Photo-

points should be recorded at an oblique angle such that the revegetation area and the horizon are

visible in the image. Successive photo-points should maintain the same view angle to allow direct

comparison over time. At least three photopoints will be provided for each management zone. The

location and image data from photo points will be provided in the final report (refer Section 5.4).

5.2 Management area inspections

The management zones should be inspected by foot and traversed to the extent required to inform

weed control program. Areas where weed cover is low or zero do not need to be regularly inspected.

Areas of weed species cover should be identified for management and photographs taken of

significant features.

Vegetation condition within management areas should be assessed and mapped as outlined in

Section 5.1.1.

5.3 Evaluation

Evaluation criteria for performance against the restoration objectives are outlined in Table 5. The

criteria include structural and compositional requirements related to the target ecosystem of FCT 20c

(refer to Section 3.2) and criteria for assessing vegetation condition (adapted from DoEE 2016 with

reference to Keighery (1994) and Casson et al. (2009), and comments by the DPaW on this RVMP).

The criteria are expected to be assessed by either the revegetation contractor or project

environmental consultant. If the criteria are met after three years, the rehabilitation can be

considered complete. If unforeseen factors impact upon rehabilitation areas (such as unauthorized

access, bushfire or vandalism) the rehabilitation should be assessed based on its trajectory at the

time and contingency actions considered following discussion with the City of Swan.

5.4 Reporting

Following the three-year rehabilitation program, a report summarising rehabilitation outcomes will

be provided to DPaW (and the City of Swan if required).




6 Implementation

As outlined in Section 1.1, the requirement and implementation of this RVMP is expected to be a

condition of subdivision. Therefore, the RVMP will be implemented following the LSP amendment

and subdivision of the adjacent development area within Lot 102.

Pre-planning for implementation of works may occur prior to subdivision, including seed collection. If

bulk earthworks or clearing occur within Lot 102 prior to subdivision, the relevant components of the

RVMP may be implemented, such as management zone preparation and translocation works.

The tasks that may be completed within the site and Lot 102 are summarised below:

• Collect seed from native species within Lot 102.

• Prepare revegetation areas for translocation, direct seeding and planting.

o Translocate vegetation in late autumn.

• Plant tubestock in late autumn / winter period.

o Direct seed in late autumn / winter period.

o Undertake weed control in management and revegetation areas.

• Inspect revegetation areas to evaluate performance against evaluation criteria (refer

Section 5.3).

o Undertake contingency actions (plant ordering) if required.

o Inspect management and revegetation areas to evaluate weed over and requirement for

weed control.

o Program weed control actions as required.

6.1 Program tasks and timeframes A schedule of implementation is provided as Table 6.

6.2 Contingency Contingency actions will only be required should success criteria (Table 5) be determined

not to have been met. These may include ordering and installing supplementary

tubestock and weed control. Contingency actions would only be undertaken in years 2, 3

and 4 (Table 6).

If criteria are not met due to unforeseen factors, or over small areas due to issues with

implementation, the relevant tasks may be repeated. Note that weed control, translocation,

tubestock planting and direct seeding can result in variable outcomes, due to uncontrollable or

unpredictable factors like extreme weather events, seasonal variation in rainfall or temperature and

differences in landform, soil or biology. In addition, if predation (by rabbits for example) and/or

physical disturbance (such as vandalism) occurs these factors may impact outcomes within

revegetation areas.

Where it is demonstrated that the prescribed methods have been ineffective, alternative methods

may be sought and adopted that better achieve the desired outcomes. In the event that this is

required, further liaison with the City of Swan (or the clearing authority associated with the

subdivision condition) is recommended to confirm the acceptability of any modification to proposed

methodology.

6.3 Roles and responsibilities

Peet Limited will be responsible for the implementation of this RVMP over a 3 year period only. After

this period, the site will be transferred to the Crown and continued to be managed for conservation

purposes. At this time, the content and outcomes of the RVMP should be reviewed by the

responsible management authority.

Peet Limited commits to implementing the RVMP such that after the 3 years the site has met, or is

on a trajectory to meet, the evaluation criteria.
