September 2011). possible, stockpiled topsoil should be directly replaced on disturbed areas;

 Minimise soil disturbance during clearing and practice standard vehicle hygiene to ensure introduced (exotic) species do not become established within the area;

 Avoid or minimise any impacts on:

 The road verges supporting denser stands of Corymbia calophylla and Agonis flexuosa (fauna habitats)

 Threatened Ecological Communities (TECs) Corymbia calophylla – Xanthorrhoea preissii (CcXp) and Corymbia calophylla – Kingia australis (CcKa); and

 The degraded remnants on the road verges of Simpson Road and east of Simpson Road (south of the creekline that crosses from east to west over the north-south section of Simpson Road). The latter should be feasible as there are already some gaps in these communities near gates.

 The period for which the pits are dewatered will be minimised, thereby shortening the period for potential drawdown;

 Dewatering will be timed with winter as far as practical thereby reducing likelihood of wetland vegetation stress;

 Periodic review of the site species list to determine that the priority status of any particular species has not changed;

 Minimise the timeframe between disturbance and rehabilitation. Monitor and manage dust as per established EMP’s during clearing and mining operations;

 Quarterly visual assessment of vegetation health, including weed assessment, will be undertaken for designated areas of vegetation remaining adjacent to the project area; and

 Monitor vegetation health on a monthly basis in groundwater dependant areas at risk when dewatering activity is occurring.

In the event that monitoring demonstrates adverse trends the following actions (individually or in combination) will be implemented:

 There is some flexibility within the mining sequence to enable mining to move to alternative pits should adverse

drawdown be noted within the vicinity of one particular pit;

 Short term cessation of activities likely to be causing the drawdown until such time as conditions allow for recommencement (e.g. soil moisture recharge due to rainfall, or alternatively via irrigation); and

 Artificial irrigation of the affected areas and/or modification of mining activities.

Southern Extension to the Dardanup On 10 April 2012 Doral submitted a supplementary information package to constitute preliminary documentation relevant Mineral Sands Project, Henty WA, to the EPBC Act 1999 referral of the proposed southern extension to the Dardanup Mineral Sands Project. The key EPBC Act Referral (EPBC commitments in relation to flora and vegetation are as follows: 2011/6087) Consolidated Preliminary Documentation (Aurora  Direct offsets include the retention, enhancement (through rehabilitation outlined above) and conservation (in Environmental, 2012b) perpetuity) of 19ha of Woodland Habitat. This commitment is addressed in the Rehabilitation Management Plan (DMS EMP 6.1);

 Indirect offsets will include the improvement in the management of Degraded and Completely Degraded habitat subject to rehabilitation and installation of artificial hollows within the offset area. This commitment is addressed in the Rehabilitation Management Plan (DMS-EMP-6.1);

 Visual monitoring will be undertaken within the Woodland Habitat Rehabilitation and Offset Area (WHROA) on a quarterly basis during each season for three years post mining;

 A minimum of 10 photo-points will be established in WHROA to allow a visual comparison of changes in vegetation structure and composition over time;

 The following targets will be used to assess rehabilitation success and to identify areas that require additional planting and/or weed treatment:

• A total surviving tree count of 1,720 (1,600 Black Cockatoo habitat trees); • 75% survival of understorey seedlings (a subjective measure based on visual assessment of species composition, plant density and plant health) documented through the quarterly monitoring; • Species representation (acceptable survival of at least 75% of species planted in each area); and • Presence of weeds (a reduced number of weeds compared to surrounding comparable areas). If these performance criteria are not met then remedial action including supplementary planting and weed control will be undertaken as required so that the completion criteria can be satisfied. Compliance with these targets will be recorded

2 VEGETATION DESCRIPTION

2.1 DARDANUP MINE

As part of the Dardanup Mineral Sands Project CER (ISK Minerals Pty Ltd, 1991) a vegetation survey was undertaken in September 1991 (EM Mattiske and Associates, 1991) for the Dowdells Line road corridor (from Guimelli Road north to South West Highway), Edwards Road (as far east as the gravel pit reserve) and Simpson Road. An emphasis was placed on searching for rare or restricted plant species and broad definition of plant communities.

The survey identified 104 plant species of which 75 were native. No Declared Rare or Priority flora were identified. A review of the species listed was conducted in February 2009 to ensure that no species have since been gazetted (ISK Minerals Pty Ltd, 1991).

The predominant vegetation of the survey area prior to disturbance was described as a forest of Corymbia calophylla (Marri) with Eucalyptus marginata (Jarrah) co-occurring on higher and better drained sites. The western and north western parts of the mining region were observed to support a mixture of vegetation types including a woodland of Eucalyptus rudis (Flooded Gum) and Melaleuca rhaphiophylla (Swamp paperbark) and low woodlands of M. rhaphiophylla, M. preissiana (Moonah) and Casuarina obsea (Swamp Sheoak) (ISK Minerals Pty Ltd, 1991).

2.2 SOUTHERN EXTENSION TO THE DARDANUP MINERAL SANDS PROJECT

Mattiske Consulting Pty Ltd (2011a) undertook a spring flora and vegetation survey in accordance with EPA Guidance Statement 51: Terrestrial Flora and Vegetation Surveys (EPA, 2004) for the DSE. The purpose of the survey was to re-validate the previous survey data (Coffey Environment, 2009b), particularly with respect to the presence of TECs and the potential impacts of proposed mining operations. Field surveys were conducted initially in September and October 2009 (Coffey Environments, 2009b) and in November 2010 (Mattiske Consulting Pty Ltd, 2011).

A total of 100 vascular plant taxa from 87 plant genera and 37 plant families were recorded within the proposed southern extension survey area. The majority of taxa recorded were representatives of the Poaceae (13 taxa), Fabaceae (13 taxa), Myrtaceae (8 taxa), Asteraceae (7 taxa) and Proteaceae (6 taxa) and families.

The DSE occurs within the Guildford vegetation complex as defined by Heddle et al. (1980). The Guildford complex, is defined as “a mixture of open forest to tall open forest of Corymbia calophylla- Eucalyptus wandoo-Eucalyptus marginata and woodland of Eucalyptus wandoo. Minor components include Eucalyptus rudis-Melaleuca rhaphiophylla”.

The Guildford Vegetation Complex has been largely cleared for agricultural activities and is under represented in the conservation estate (Government of Western Australia, 2000). It is estimated that 4.4% of the original extent remains on the southern Swan Coastal Plain within the Greater Bunbury Region. Of the 4.4%, there is only 0.4% in existing and proposed Regional Open Space (EPA, 2003). The remnant vegetation is considered regionally significant under the Rarity criterion set out in EPA Guidance No.10 (EPA, 2006).

A portion of the DSE occurs on the Whicher Scarp and contains vegetation described as Whicher Scarp (WC) - Open Forest of Eucalyptus marginata subsp. marginata-Corymbia calophylla on escarpment with some Corymbia haematoxylon, Banksia attenuata and Xylomelum occidentale in humid zone (Mattiske and Havel, 1998).

Doral Mineral Sands Pty Ltd 14 DMS-EMP-11.1 Flora and Veg EMP.doc 06 August 2012 Flora and Vegetation Management Plan Dardanup Mine and Burekup West Doral Mineral Sands Pty Ltd 2.2.1 Vegetation Condition Mattiske Consulting Pty Ltd (2011) classified the vegetation within the DSE as either Degraded or Completely Degraded, according to the condition scale of Keighery (1994). It is estimated that of the 77.46ha of proposed ground disturbance that:

 3.53ha (4.6%) of clearing is considered Degraded vegetation; and

 73.93ha (95.4%) of clearing is considered Completed Degraded vegetation.

The majority of this (59.46ha) consists of pasture and/or planted vegetation, while the remaining 18ha is native vegetation.

2.2.2 Flora of Significance No Declared Rare Flora (DRF) species, pursuant to subsection (2) of section 23F of the Wildlife Conservation Act 1950 and as listed by the DEC (Mattiske Consulting Pty Ltd, 2011, p13) were recorded within the DSE.

No flora, pursuant to the EPBC Act 1999, and as listed by the DSEWPaC (Mattiske Consulting Pty Ltd, 2011, p13) were recorded within the DSE.

No priority flora species as listed by the DEC (Mattiske Consulting Pty Ltd, 2011a, p13) were recorded within the DSE.

2.2.3 Vegetation Communities of Significance

Thirty five vegetation communities were defined and mapped within the DSE (Figure 2). Two communities defined as having values in common with the SCP3 and SCP3b TECs (Mattiske Consulting Pty Ltd, 2011a, p21) are located within the DSE, following comparisons with Swan Coastal Plain Floristic Communities as defined by Gibson et al. (1994) and Whicher Scarp Communities as delineated by Keighery et al. (2008). These two communities comprise:

 Eucalyptus calophylla - Xanthorrhoea preissi woodlands and scrublands, Swan Coastal Plain (CcXp) – overlap with SCP3c Swan Coastal Plain floristic community (Gibson et al., 1994); Critically Endangered at State level and Endangered at Federal level; and

 Eucalyptus calophylla- Kingia australis woodlands and scrublands, Swan Coastal Plain, (CcKa) – overlap with SCP3c Swan Coastal Plain floristic community (Gibson et al., 1994); Critically Endangered at State level and Endangered at Federal level.

The location of these two communities is within the road side vegetation of Simpson Rd and in the central Lot 110, Simpson Road as shown on Figure 2. Mattiske Consulting Pty Ltd (2011a) classified these areas as Degraded from grazing activities and from invasive species on the road verges have less than 17% of species in common with Whicher Scarp Community type ‘E’, as defined by Keighery et al. (2008).

2.2.4 Weeds

Of the 100 taxa recorded within the DSE, 37 of these were introduced (exotic). Of these, one taxon Gomphocarpus fruticosus is currently a listed Declared Plant species pursuant to section 37 of the Agricultural and Related Resources Protection Act 1976.

2.3 BUREKUP WEST

Burekup West (i.e. the Western Extension) is located within the Swan Coastal Plain Bioregion and is situated 2km to the west of the North Whicher Scarp Area.

Doral Mineral Sands Pty Ltd 15 DMS-EMP-11.1 Flora and Veg EMP.doc 06 August 2012 Flora and Vegetation Management Plan Dardanup Mine and Burekup West Doral Mineral Sands Pty Ltd In a regional context, Burekup West lies within the Drummond Botanical Subdistrict of the Southwest Botanical provence as recognised by Diels (1906) and later refined by Gardner (1942) and Beard (1979 and 1980).

Beard (1990) described the Drummond Botanical Subdistrict as being a low-lying coastal plain with sandy soils and swampy deposits, and having a warm dry Mediterranean climate with 5-6 dry months per year. Vegetation of the Drummond Botanical Subdistrict is typically Banksia low woodland on leached sands, Melaleuca wetlands in areas of poorer drainage and Eucalyptus gomphocephala/Eucalyptus marginata/Corymbia calophylla woodlands on soils with a higher nutrient content (Beard 1990).

Burekup West occurs within the Guildford vegetation complex as defined by Heddle et al. (1980). The Guildford Complex is defined as “A mixture of open forest to tall forest of Corymbia calophylla- Eucalyptus wandoo-Eucalyptus marginata and woodland of Eucalyptus wandoo. Minor components inside Eucalyptus rudis-Melaleuca rhaphiophylla”. The Swan Coastal Plain Bioregion is characterised by Banksia spp. and Eucalyptus gomphocephala (Tuart) woodlands on sandy soils, Casuarina obesa woodlands on outwash plains (with Corymbia calophylla to the south), and Melaleuca spp. woodlands on swampy areas (Mattiske Consulting Pty Ltd, 2006). This vegetation complex has been largely cleared for agricultural activities.

Iluka commissioned Mattiske Consulting Pty Ltd to conduct a vegetation survey on leases M70/720 and M70/652 and its surrounds over two seasons (Mattiske Consulting Pty Ltd, 2006 and 2007). The study area has been extensively cleared for agricultural purposes and contains isolated trees and several areas of native vegetation.

Following the transfer of proponent (Iluka to Doral) Coffey Environments conducted a site visit on 12 September 2008 with DEC (Bunbury) and Doral staff. Areas of environmental significance that may be impacted by the proposal were visited and a broad appraisal of vegetation communities and their general condition was conducted.

In the flora and vegetation surveys conducted by Mattiske Consulting Pty Ltd (2006 and 2007), a total of 199 taxa (including subspecies and varieties) from 139 genera and 53 families were recorded within the Burekup West study area. A total of nine vegetation communities were recorded in the Burekup West area, seven of which occur inside the proposed Burekup West disturbance area (Figure 3). The study area was found to be in a Degraded or Completely Degraded state largely as a result of agricultural practices and grazing. The majority of the communities were Degraded and ranged from Completely Degraded to Good (Figure 4).

2.3.1 Flora of Significance

No DRF were located during surveys, although several Priority species have previously been recorded in or near the area (Figure 5). Historical records indicate that two priority species, Aponogeton hexatepalus (Priority 4) and Grevillea rosieri (Priority 2) occur at two locations within the Burekup West proposal area. These species were not found in the Mattiske Consulting Pty Ltd (2006 and 2007) surveys.

Grevillea rosieri

Grevillea rosieri (Priority 2) was recorded in the eastern part of the project area (near Offer Road). This taxon is known currently from eight records at the State Herbarium. The occurrence of the Grevillea rosieri appears unusual in that it is known from Kalannie and Mollerin in the Wheatbelt and Florabase (DEC, 2007) suggests that one of the recordings may be a planting out of its range.

Doral Mineral Sands Pty Ltd 16 DMS-EMP-11.1 Flora and Veg EMP.doc 06 August 2012 Flora and Vegetation Management Plan Dardanup Mine and Burekup West Doral Mineral Sands Pty Ltd A targeted flora survey, including a review of previous vegetation surveys and the DEC florabase was undertaken by Coffey Environments (2009a) to verify a DEC record of the identification and location of the Priority 2 species Grevillea rosieri in the proposed amendment area of Burekup West.

Grevillea rosieri was not previously recorded by Mattiske Consulting Pty Ltd (2006 and 2007). The 2002 DEC florabase records showed that the GPS coordinate location and the locality description was not consistent (Figure 5). Both locations were included in the targeted survey undertaken by Coffey Environments (2009a).

Coffey Environments (2009a) recorded three Grevillea rosieri specimens within the roadside vegetation 0.7km south of Henty Brook Road on Offer Road. The location of the Grevillea rosieri was 0.7km further north along Offer Road than the 2002 DEC database locality description. The location of the three Grevillea rosieri specimens is well outside (approximately 0.6km) the proposed amendment area (Figure 4). According to correspondence by the DEC, the population is not considered to be native or significant to the area (Coffey Environments, 2009a).

Doral have liaised with DEC to update the florabase record with the results of this targeted flora survey, including the new location coordinates for Grevillea rosieri (see letter dated 16 December 2010 in EMS). The DEC will refer the matter to the WA Herbarium, as they manage this database. However the DEC have noted, that this record may not be amended due to the possibly of it being a historical record for the area and as the record states ‘scattered along disturbed road verge’.

The DEC have suggested Doral submit a specimen of the population found 0.7 km south of Henty Brook Road to the WA Herbarium, to be added to the WA Herbarium’s database and a point recorded for this location. The current location where Grevillea rosieri was identified along Offer Road has been surrounded by yellow markers to ensure Doral personnel and contractors are aware of the existence of this priority species. Doral is presently waiting for the plants to fruit.

Aponogeton hexatepalus

Aponogeton hexatepalus (Priority 4) has been recorded in two locations previously within the proposal area (near St Helena Road). This taxon required local ponding and seasonally wet conditions. This taxon is known currently from 25 records at the State Herbarium and is known to occur from Perth southwards on the Swan Coastal Plain. Coffey Environments requested a species specific search of the DEC’s Threatened Flora Database for A. hexatepalus. The results of the database search show that there are 71 known records of the species, 13 of which are in the general locality of the Burekup area. Of the 13 records (4,500 plants) eight are located to the north west of the Burekup West project area in the railway reserve adjacent to Southwest Highway, one record (70 plants) occurs within the Burekup West project area and one record (300 plants) to the west of the Burekup West project area.

The record in Burekup West was located on the northside of St Helena Road, 150m west of the Dowdells Line intersection in the roadside verge. The population was first recorded in August 1985 (20 plants), resurveyed in 1990 (50 plants) and again in 1993 (70 plants).

Mattiske Consulting Pty Ltd (2006 and 2007) did not record A. hexatepalus within the survey area. As this species is highly dependent on seasonally wet conditions and ponding it is highly unlikely that presence of A. hexatepalus would have been recorded.

A targeted spring survey was undertaken by Coffey Environments (2009a) of the recorded Aponogeton hexatepalus population on St Helena Road, Dardanup (Figure 5). The survey was undertaken to comply with commitment 789:P:15 (part) of the EPS.

The survey area included the roadside vegetation on the northern side of St Helena Road 100m either side of the DEC rare flora marker. Two transect lines of 200m in length were systematically traversed on foot searching one metre either side of the transect line for the species. Adjacent areas including

Doral Mineral Sands Pty Ltd 17 DMS-EMP-11.1 Flora and Veg EMP.doc 06 August 2012 Flora and Vegetation Management Plan Dardanup Mine and Burekup West Doral Mineral Sands Pty Ltd the roadside vegetation on the southern side of the road and the concrete drain were also searched. Surface water was present in ruts on the north side of the road and a drain on the southern side during both survey times.

After an extensive search of the roadside vegetation verge, A. hexatepalus was not recorded during the Coffey Environments (2009a) targeted survey.

The report recommended that Doral consult with the Threatened Species and Communities Branch of the DEC on the results of the survey for the Aponogeton hexatapalus population on St Helena Road and to determine whether any further survey work or management strategies are required.

Consultation between Doral and the DEC continued throughout 2010 with a letter requesting the removal of the record from the DEC database sent with a copy of the targeted flora survey report on 16/2/2010. At the time of compilation of this document, ongoing site flora surveys of the area are being conducted by the DEC.

Further inspection by DEC in 2010 confirmed A. hexatepalus was not present and also determined that the presence of this species was unlikely due to agricultural drainage.

2.3.2 Vegetation Communities of Significance

No TECs were identified in the Burekup West project area (Mattiske Consulting Pty Ltd (2006 and 2007).

2.3.3 Other Flora of Interest

The Low Woodland of Casuarina obesa (mapped as C3 on Figure 3) is thought to be the southernmost stand on the eastern side of the Swan Coastal Plain, and therefore is considered a significant occurrence.

The stand of Eucalyptus wandoo (mapped as E1 on Figure 3) is one of the most extensive known stands of mixed age on the southern portion of the Pinjarra Plain. The majority is located outside of the Burekup West disturbance area.

Mountain Marri (Corymbia haemotoxylon) (mapped as C5 on Figure 3) located in the Waterloo roadside vegetation verge is a disjunct and significant population. Corymbia haemotoxylon is considered to be a distinguishing feature of the Whicher Scarp vegetation and is normally associated with the middle and upper slopes of the central and southern sectors of the Scarp (Keighery et al., 2008). The Burekup West disturbance area is located approximately 1km to the east of Waterloo Road and is not expected to have a direct impact on Corymbia haemotoxylon.

2.3.4 Weeds

A total of 86 of the 199 taxa recorded in the flora survey were introduced or weed species (Mattiske Consulting Pty Ltd, 2006). Four of the 86 species are Declared Plants pursuant to Section 37 of the Agriculture and Related Resources Protection Act 1976. They were:

 Acacia dealbata (Silver Wattle) P1, P2;

 Rubus fruticosus agg. (Blackberry) P1, P4;

 Asparagus asparagoides (Bridal creeper) P1;

 Gomphocarpus fruticosus (Narrowleaf Cotton Bush) P1, P4; and

 Rubus fruticosus agg. (Blackberry) and Asparagus asparagoides (Bridal creeper) are listed by the Commonwealth as Weeds of National Significance (WONS).

3 POTENTIAL IMPACTS

3.1 DARDANUP MINE

The Dardanup Mineral Sands Project has the potential to disturb restricted areas of remnant but highly modified vegetation located along road reserves and on private land (ISK Minerals Pty Ltd, 1991).

3.2 SOUTHERN EXTENSION TO THE DARDANUP MINERAL SANDS PROJECT

The potential impacts to Flora and Vegetation have been identified below: i) Direct loss of vegetation due to the proposed land clearing required for development of the new DSE mining area. Approximately 18.00ha of native vegetation will be cleared for the DSE. In addition 59.93ha of pasture and 0.044ha of planted vegetation will be disturbed. Of this combined disturbance area (77.45ha) a total of 809 trees will be cleared. The vegetation has been classified as either Degraded (3.53ha) or Completely Degraded (73.93ha) (Mattiske Consulting Pty Ltd, 2011). The location of the proposed vegetation to be cleared is shown on Figure 2. ii) Indirect impact on vegetation of groundwater drawdown as a result of dewatering.

The impact that groundwater drawdown has on ecosystems is related to the level of dependence that the ecosystem has on groundwater, the level of drawdown, the rate of drawdown and the duration of drawdown. Investigation into soil profiles and groundwater dynamics across the DSE show that Groundwater Dependent Ecosystems (GDEs) in the study area (Figure 2), including two vegetation communities with affinities to TECs, are underlain by shallow sands over a lens of clay (at an average depth of 1-4mBGL), upon which ground water perches as a result of rainfall. The clay layer ensures that groundwater is relatively constant for these communities as it is not likely to be affected by changes in the Superficial Aquifer (Parsons Brinkerhoff, 2012). Due to the presence of clay lenses over the Superficial Aquifer, perched groundwater has been shown to sustain remaining vegetation in previous phases of mining (i.e. Burekup West). Perched groundwater, coupled with water retained in the relatively impermeable loam/clay soil has been sufficient to maintain tree health regardless of the Superficial Aquifer being dewatered iii) Introduction and spread of weeds;

The main method of spread of weeds would be through the introduction of infected materials to uninfected areas. Land disturbance provides an opportunity for weed species to establish in areas. iv) Direct impact on vegetation of dust. v) Impacts to TECs.

Activities that are most likely to result in impact to the two communities (present in the project area) mapped as having values in common with TECs SCP3a and SCP3b are clearing and dewatering.

The tall woodland of Corymbia calophylla over Xanthorrhoea pressii and Solanum laciniatum (CcXp*Si) is located outside of the DSE project area within the ’Waterloo Block’ (Lot 110) and will not be impacted by the DSE project.

The closed forest of CcXp and the tall woodland of CcKa is located along the roadside vegetation along Simpson Road on the northern boundary of the site. A haulroad will traverse through the vegetation community (considered in a Degraded condition by Mattiske Consulting Pty Ltd, 2011). Approximately 0.1532ha of community type CcXp may be impacted as a result of the conveyor crossing. The understorey at the crossing consists of predominately pasture grasses and no overstorey trees would

Doral Mineral Sands Pty Ltd 19 DMS-EMP-11.1 Flora and Veg EMP.doc 06 August 2012 Flora and Vegetation Management Plan Dardanup Mine and Burekup West Doral Mineral Sands Pty Ltd be directly impacted. The impact to this community will be minimised as much as possible (see Plate 1 below) by the strategic alignment of the haulroad to avoid the clearing of trees and minimizing of disturbance by the diversion of vehicle access roads around the vegetation community.

Plate 1: Haul Road Location on Simpson Rd Investigation into soil profiles and groundwater dynamics across the DSE show that communities CcKa, CcXp and CcXpSi are underlain by shallow sands over a lens of clay (at an average depth of 1-3m BGL), upon which ground water perches as a result of rainfall. The clay layer ensures that groundwater is relatively constant for these communities as it is not likely to be affected by changes in the Superficial Aquifer (Parsons Brinkerhoff, 2012). Perched groundwater, coupled with water retained in the relatively impermeable loam/clay soil is expected to maintain tree health regardless of the Superficial Aquifer being dewatered.

3.3 BUREKUP WEST

The potential impacts to Flora and Vegetation have been identified below: vi) Direct loss of vegetation due to the proposed land clearing required for development of the new mining area. Native vegetation to be cleared comprises:  0.13ha rated as Very Good;

 2.04ha rated as Good; and

 25.15ha rated as Degraded (9.2ha is Completely Degraded agricultural land).

The remaining land in the disturbance area has already been cleared for pastoral grazing. vii) Remnant vegetation in the western extension area is considered regionally significant as it is part of the poorly reserved (4.4% of pre European is remaining) Guildford Vegetation Complex (EPA, 2003). The area to be cleared that rates as Good or Very Good represents 0.15% (2.17ha) of the remaining Guildford Vegetation Complex. The distribution of native vegetation to be cleared and its condition rating is shown on Figure 3 and Figure 4. viii) Indirect impact on vegetation of groundwater drawdown as a result of dewatering.

Doral Mineral Sands Pty Ltd 20 DMS-EMP-11.1 Flora and Veg EMP.doc 06 August 2012 Flora and Vegetation Management Plan Dardanup Mine and Burekup West Doral Mineral Sands Pty Ltd The impact that groundwater drawdown has on ecosystems is related to the level of dependence that the ecosystem has on groundwater, the level of drawdown, the rate of drawdown and the duration of drawdown. Groundwater drawdown impacts on vegetation have been assessed for the western extension area using maximum predicted groundwater drawdown contours and the GDE class. The response curves and risk assessment methodology from Froend, Bowen and Associates (2004) have been adapted to assess risk levels.

The locations of communities that have some degree of dependency on groundwater are shown in Figure 6. The impact of ground water drawdown may impact Community C1 (1.3ha), Community C2 (1.6ha), Community C3 (3.7ha), Community M1 (1.7) and Community M2 (0.9ha) (SWC, 2007b). Refer to Figure 3 for Community Type locations. ix) Introduction and spread of weeds;

The main method of spread of weeds would be through the introduction of infected materials to uninfected areas. Land disturbance provides an opportunity for weed species to establish in areas. x) Direct impact on vegetation of dust. xi) Direct impact on vegetation of road widening (there are no plans to widen Waterloo Road).

3.4 AMENDMENT AREA TO BUREKUP WEST

The potential impacts from mining the amendment area to Burekup West are:

 Approximately 2.43ha (0.09ha rated as Good and 2.34ha rated as Degraded) of native vegetation will be cleared; and

 An isolated clump of trees north of Simpson Road and east of Dowdell’s Line which are 20% groundwater dependent may be impacted by groundwater drawdown.

3.5 NORTHERN AMENDMENT TO BUREKUP WEST

The potential impacts from mining the additional pit include:

 Approximately 0.05ha of Degraded native vegetation will be cleared.

4 MANAGEMENT AND MONITORING MEASURES

4.1 DARDANUP MINE

Table 2 outlines the management and monitoring measures to address the potential environmental impacts to flora and vegetation in relation to the Dardanup Mine. Given that this area is operational the control measures have been divided into two categories for ease of implementation:

 Operational Phase; and

 Post Mining Phase.

All management and monitoring measures have been sourced from the “Pre-Construction Environmental Approvals Supporting Documentation” (GHD 2001). These management and monitoring measures have been reassessed in relation to operations in 2009 and have been revised accordingly.

4.2 SOUTHERN EXTENSION TO DARDANUP MINERAL SANDS PROJECT

Table 3 outlines the management and monitoring measures to address the potential environmental impacts to flora and vegetation as outlined in Section 3. These control measures have been divided into three categories for ease of implementation:

 Pre-Mine Establishment Phase;

 Operational Phase; and

 Post-Mining Phase.

The majority of post mining activities are comprehensively addressed in the Rehabilitation Management Plan Dardanup Mine and Burekup West (DMS-EMP-6.1).

4.3 BUREKUP WEST

Table 4 outlines the management and monitoring measures to address the potential environmental impacts to flora and vegetation as outlined in Section 3. These control measures have been divided into two categories for ease of implementation:

 Pre-Mine Establishment Phase; and

 Operational Phase.

The majority of post mining activities are comprehensively addressed in the Rehabilitation Management Plan Dardanup Mine and Burekup West (DMS-EMP-6.1).

Soil moisture bores installed at the Low Woodland of C. obesa, CCW and REW have been renamed from BU (Burekup) prefix to SM (Soil Moisture) as of 1 December 2009:

 BU019 – SM001;

 BU020 – SM002;

 BU021 – SM003;

 BU022 – SM004; and

 BU023 – SM005.

Doral Mineral Sands Pty Ltd 22 DMS-EMP-11.1 Flora and Veg EMP.doc 06 August 2012 Flora and Vegetation Management Plan Dardanup Mine and Burekup West Doral Mineral Sands Pty Ltd 4.4 AMENDMENT TO BUREKUP WEST

Additional vegetation transects (9a, 9b and 10) and one soil moisture bore (SM006) have been installed and will be managed in accordance with Ministerial Statement 789 Condition 6-2, in order to monitor any impacts on:

 The isolated clump of trees (groundwater dependent) north of Simpson Road; and

 Simpson Road verge vegetation, at the southern end of the amendment area.

An additional soil moisture bore has been installed (SM007) for the Simpson Road verge vegetation in summer 2011.

4.4.1 Threatened Ecological Communities (TECs)

There were no TECs recorded in the study area (Mattiske Consulting Pty Ltd, 2006 and 2007) which included the proposed amendment area. However, a localised patch of Corymbia calophylla (Community C4) that has similar dominant species to TEC Community type SCP3a occurs in the study area which is listed as Critically Endangered by the State and Endangered under the EPBC Act 1999 (Mattiske Consulting Pty Ltd, 2006). The overall similarity is very low due to the highly degraded condition of the vegetation in the road reserve (Mattiske Consulting Pty Ltd, 2007).

TEC SCP 3a is described as Corymbia calophylla-Kingia australis woodlands on heavy soils. The C4 community is restricted to 0.6ha (rated Good) in Simpson Road verge. This roadside vegetation is directly adjacent to the proposed Amendment Area (Figure 5).

The roadside vegetation will not be cleared along Simpson Road, however there may be impacts on the vegetation from groundwater drawdown. The maximum predicted groundwater drawdown (Parsons Brinckerhoff, 2011) in the area is 0.5m (Figure 7).

Potential mitigating measures:

 Set up of a groundwater monitoring piezometer to measure monthly groundwater levels;  Set up of a vegetation monitoring transect, measuring vegetation health and photo-point monitoring; and  Monitor vegetation health on a monthly basis.

4.4.2 Groundwater Dependant Ecosystem (GDE)

The GDE vegetation community is located directly west of the proposed amendment area to the Burekup West Mine (Figure 6). Mattiske Consulting Pty Ltd (2006 and 2007) mapped the GDE vegetation north of Simpson Road as a M1 vegetation community consisting of a Low woodland of Melaleuca rhaphiophylla with emergent Corymbia calophylla and Eucalytpus rudis over pasture on loam soils in a Degraded condition. The ground truthing of this vegetation community by Coffey Environments (2009a) identified the vegetation community as consisting of a Low Woodland dominated by Melaleuca preissiana with minor Melaleuca rhaphiophylla and Eucalyptus rudis over an open sedgeland of Juncus kraissii and Grassland of pasture grasses and is in a Degraded condition. The original vegetation community mapping by Mattiske Consulting Pty Ltd (2006 and 2007) has been changed in this document from M1 to M2 vegetation community (Figure 3). This change in the dominant Melaleuca species (from M. rhaphiophylla to M. preissiana) provides an update on the latest vegetation data available and does not have any implications for the proposed amendment area.

Groundwater modelling (PB, 2009) has predicted a potential groundwater drawdown in the GDE area north of Simpson Road between 2-3 metres (Figure 7).

Doral Mineral Sands Pty Ltd 23 DMS-EMP-11.1 Flora and Veg EMP.doc 06 August 2012 Flora and Vegetation Management Plan Dardanup Mine and Burekup West Doral Mineral Sands Pty Ltd The impact that groundwater drawdown has on an ecosystem is related to the level of dependence that the ecosystem has on groundwater, the level, the rate and the duration of drawdown. The assessment undertaken by SWC (2007a) includes information on soil properties at the site and the water use requirements of the vegetation to determine groundwater dependence of each ecosystem present.

Potential indirect impact on vegetation in the GDE community from groundwater drawdown as a result of dewatering:

 There is a predicted low to moderate impact on the Vegetation Community M1 (now M2) (GDE area north of Simpson Road) from the predicted 2-3m groundwater drawdown. Mitigating measures already in place:

 A vegetation monitoring transect has been established in October 2009, measuring vegetation health and photo-point monitoring (Figure 8). Potential mitigating measures:

 Set up of a groundwater monitoring piezometer in the GDE community to measure monthly groundwater levels;  Monitor vegetation health on a monthly basis in the GDE area when dewatering activity is occurring; and  Undertake mining activities in close proximity to the GDE area during winter and spring months to optimize mitigation of any impacts on GDE vegetation from water table drawdown.

 There is some flexibility within the mining sequence to enable mining to move to alternative pits should adverse drawdown be noted within the vicinity of one particular pit;

 Short term cessation of activities likely to be causing the drawdown until such time as conditions allow for recommencement (e.g. soil moisture recharge due to rainfall, or alternatively via irrigation); and

 Artificial irrigation of the affected areas and/or modification of mining activities.

The following targets will be used to assess rehabilitation success within the WHROA and to identify areas that require additional planting and/or weed treatment:  A total surviving tree count of 1,720 (1,600 Black Cockatoo habitat trees);

 75% survival of understorey seedlings (a subjective measure based on visual assessment of species composition, plant density and plant health) documented through the quarterly monitoring;

 Species representation (acceptable survival of at least 75% of species planted in each area); and

 Presence of weeds (a reduced number of weeds compared to surrounding comparable areas).

If these performance criteria are not met then remedial action including supplementary planting and weed control will be undertaken as required so that the completion criteria can be satisfied. Compliance with these targets will be recorded during the quarterly visual monitoring.

Appendix B Vegetation Clearing Operating Procedure

Flora and Vegetation Management Plan Dardanup Mine and Burekup West Doral Mineral Sands Pty Ltd Operating Procedure DMS-EP11.1

Vegetation Clearing Procedure- Burekup West and Dardanup Southern Extension

Purpose The purpose of this operating procedure is to provide a detailed outline of how to minimise the impact of vegetation clearing within Burekup West and the Dardanup Southern Extension (DSE). The DMS-EP-9.1 Fauna Spotter Operational Procedure Burekup West and Dardanup Southern Extension should also be referenced as it outlines how to manage fauna when clearing vegetation. In addition the Department of Sustainability, Environment, Water, Population and Conservation (DSEWPaC) requires Doral to comply with EPBC Condition 2 for the Dardanup Southern Extension project and to clearly outline this condition in the Vegetation Clearing Procedure Burekup West and Dardanup Southern Extension:

Condition 2 – The person taking the action must not clear: a. More than 13.7ha of black cockatoo foraging habitat. Area to be cleared includes two identified potential breeding tress (H1 and H2). b. Potential breeding trees know to contain hollows suitable for breeding, other than the two identified in condition 2a. These potential breeding trees must be avoided during construction and operation. c. Native vegetation in the areas identified as the Woodland Habitat Rehabilitation and Offset Area (WHROA).

Procedure 1. Use clean machinery, or if required wash machinery prior to use, when clearing vegetation to prevent the spread of weeds and/or dieback; 2. Vegetation requiring clearing should be clearly marked and delineated with temporary fencing. The fences should be marked with adequate flagging tape to increase visibility. These areas should be clearly identified on an aerial map; 3. Use temporary fencing to protect any vegetation to be retained that will be at risk from machinery activity; 4. Prior to removal of topsoil, recover any millable timber. Chip cleared vegetation and use as mulch for soil stabilization. Strip low scrub with the topsoil; 5. Plan to utilise multiple use easements to minimise vegetation clearing and restrict vehicles and mining equipment to designated roads and mining areas; 6. Locate facilities such as tailings storage ponds on existing cleared areas or future mining areas wherever possible; and 7. All clearing contractors should be verbally inducted about the clearing process and be familiar with the DMS-EP-9.1 Fauna Spotter Operating Procedure.

1 September 2012 1 Responsibilities It is the responsibility of the OHS & E Superintendent to ensure compliance with this operational procedure.

Flora and Vegetation Management Plan Dardanup Mine and Burekup West Doral Mineral Sands Pty Ltd Operating Procedure

DMS -EP10.7 Perched Groundwater, Soil Moisture and Vegetation Health Monitoring Procedure Dardanup Southern Extension

Purpose The Department of Sustainability, Environment, Water, Population and Conservation (DSEWPaC) requires Doral to comply with Condition 6 of the proposed approval decision for the Dardanup Southern Extension (DSE) project:

The person taking the action must develop a Perched Groundwater and Tree Health Monitoring Program (the program) to be conducted for the life of the project, including the rehabilitation phase, to ensure mining excavations do not reduce water availability. The program, including trigger values and contingency measures, must be developed in consultation with local DEC officers. The program must be provided to the Department within 30 days of establishment of the program.

In addition, to ensure that mining excavations and dewatering do not reduce water availability so as to adversely affect groundwater dependent vegetation the following commitments by Doral have been made:

 Monitoring perched groundwater levels, soil moisture and vegetation health in Threatened Ecological Communities (TECs) CCKa and CcXp and the vegetation type ErMp within the proposed Woodland Habitat Rehabilitation and Offset Area (WHROA);  Monitor vegetation health on a monthly basis in groundwater dependent areas at risk when dewatering activity is occurring; and  The monitoring shall be carried out before, during and for at least 12 months after dewatering and mining has ceased, on a monthly basis.

Procedures 1. PERCHED GROUNDWATER

Perched groundwater in the DSE is unconfined and occurs above impervious layers such as clays and silts which form an unsaturated zone. Perched groundwater is generally separate from the underlying Superficial Aquifer. In the DSE, perched groundwater occurs between 1 to 4metres below ground level (mBGL) depending on the nature of the impervious clay layer. Mattiske Consulting Pty Ltd (2010) noted that the TECs CcXp and CcKa occur on soils with high clay and loam content and inferred that the low permeability of these soils was likely to slow groundwater movement through these profiles. More detailed investigation into soil profiles and groundwater dynamics across the DSE show that the TECs and other groundwater dependent ecosystems (GDEs) are underlain by shallow sands over a lens of clay (at an average depth of 1- 4mBGL), upon which ground water perches as a result of rainfall. The clay layer ensures that

DMS-EP-10.7 18 July 2012 1 groundwater is relatively constant for these communities as it is not likely to be affected by changes in the Superficial Aquifer (PB, 2012). 1.1 Perched Groundwater Monitoring Methodology

Perched groundwater levels will be monitored in Perched Water Dip Wells (PWDW) PWDW6, PWDW7, PWDW8 and PWDW9 which are located in TECs CcXp and CcKa and within vegetation type ErMp and AfEr, as shown in Figure 1. Monitoring will be undertaken on a monthly basis before, during and for at least 12 months post mining. Monitoring will commence (prior to dewatering) in July 2012. Monitoring will be undertaken by inserting a depth to water indicator into the relevant PWDW and recording the water level in mm. 1.2 Perched Groundwater Trigger Values

The following trigger values have been applied for the four PWDW’s based on perched groundwater information recorded over several seasons in Burekup West:  PWDW6 – Less than 3mBGL (outside of February to April);  PWDW7 – Less than 3mBGL (outside of February to April); and  MB29s – Less than 4mBGL (outside of February to April). It is anticipated that trigger levels will be revised following the collection of 12 months of data. 1.3 Perched Groundwater Contingency Measures

In the event that monitoring demonstrates adverse trends, in consultation with the DEC, the following actions will be implemented:  The sequence of mining may be altered to reduce drawdown impacts;  Short term cessation of activities until such time as conditions allow for recommencement (e.g. soil moisture recharge due to rainfall, or alternatively via irrigation); and  Artificial irrigation of the affected areas and/or modification of mining activities. 1.4 Perched Groundwater Reporting

Trend graphs for each PWDW including any contingency measures implemented will be reported and discussed in the Annual Environmental Report (AER) submitted annually on the 1st March.

DMS-EP-10.7 18 July 2012 2 2. SOIL MOISTURE MONITORING

Soil moisture monitoring will be undertaken for soil moisture access tubes SM007, SM008 and SM009 which are located within TECs CcXp and CcKa and within vegetation type ErMp (Figure 1). Soil moisture monitoring will be conducted on a monthly basis before, during and for at least 12 months post mining. Monitoring will commence (prior to dewatering) in July 2012. Monitoring will be conducted using a Neutron Hydroprobe which consists of a radioactive neutron emitting source which records the density of hydrogen atoms (present in water) thus measuring the moisture density of the surrounding soil. 2.1 Soil Moisture Methodology

Monitoring of soil moisture in the access tubes will be conducted using the following methodology: 1. Prior to conducting soil moisture monitoring in the access tubes, three sets of Neutron Hydroprobe readings (dry, medium and high) need to be calibrated against soil samples collected next to soil access tubes and analysed by a NATA accredited laboratory for soil moisture. “Dry” calibration samples will be collected during late summer/early autumn (late March/early April),“high” calibration samples will be collected in late winter / early spring (late August/September) and “medium” calibration samples will be collected in late spring / early summer (late November/December). 2. Calibration soil samples need to be collected within a 10 meter radius of all three soil moisture access tubes (SM007, SM008 and SM009). The calibration samples (soil profile) should ideally be collected using a push probe drilling technique. If ground conditions require use of an auger drilling technique, the auger flights need to be separated according to change in profile and stored in zip locked bags. 3. All calibration soil samples will be separated into distinct soil horizons and placed into ziplock bags to ensure moisture levels do not change. If samples cannot be delivered to the NATA accredited laboratory within 24 hours, samples will be frozen and sent to the laboratory on the next most suitable day. 4. On a monthly basis the Neutron Hydroprobe is then lowered down each of the soil moisture access tubes (SM007, SM008 and SM009) to measure and record the soil moisture using a neutron moderation technique. 5. Soil moisture results for the calibration soil samples and results obtained from the Neutron Hydroprobe are calibrated from the readings collected by the Neutron Hydroprobe. 2.2 Soil Moisture Trigger Values

Soil moisture access tube SM007 was installed in November 2010, with the soil moisture profile showing a seasonal variation and as such, baseline data for this location will be used as a trigger value for SM007, SM008 and SM009 in the absence of specific data for each soil moisture access tube location. Trigger values for each location will be subject to review after 12 months of monitoring.

DMS-EP-10.7 18 July 2012 3 2.3 Soil Moisture Contingency Methods

In the event that monitoring demonstrates adverse trends, in consultation with the DEC, the following actions will be implemented:  The sequence of mining may be altered to reduce drawdown impacts;  Short term cessation of activities until such time as conditions allow for recommencement (e.g. soil moisture recharge due to rainfall, or alternatively via irrigation); and  Artificial irrigation of the affected areas and/or modification of mining activities. 2.4 Soil Moisture Reporting

Trend graphs for each soil moisture access tube will be reported and discussed in the AER.

DMS-EP-10.7 18 July 2012 4 3. VEGETATION HEALTH MONITORING

A vegetation health monitoring program will be established for groundwater dependent areas within the DSE which are potentially at risk of reduced water availability during dewatering activities. Vegetation monitoring transects will be established at four sites to monitor vegetation health. Transects will be located within TECs CcKa and CcXp, vegetation type ErMp and AfEr. Transect locations are shown on Figure 1 and a description of the vegetation type for each transect is provided in Table 1. Transect 10 and 11 located with TECs CcKa and CcXp are outside of the Superficial Aquifer drawdown and are considered to represent control sites. Table 1: Description of Vegetation Monitoring Transects

Transect Location Vegetation Community Description # Description CcKa - Corymbia calophylla – Kingia australis woodlands and shrublands, Swan Coastal Plain. This community has values in Simpson Road common with SCP3b (Corymbia calophylla – Kingia australis 10 woodlands and shrublands) though demonstrates less than 17% (Control site) floristic similarity with the TEC community (Mattiske Consulting, 2011a).

CcXp - Corymbia calophylla - Xanthorrhoea preissii woodlands and shrublands, Swan Coastal Plain. This community has values in Simpson Road common with TEC SCP3a (Corymbia calophylla and Xanthorrhoea 11 (Control site) preissii woodlands) though demonstrates less than 17% floristic similarity with the TEC community (Mattiske Consulting, 2011).

Located within the ErMp - Open Woodland of Eucalyptus rudis and Melaleuca Woodland Habitat 12 preissiana over pasture grasses. Rehabilitation and Offset Area.

Along Paradise AfEr - Open Forest of Agonis flexuosa with scattered Eucalyptus 13 Creek adjacent to rudis over Pennisetum clandestinum. the mine pit.

Vegetation health monitoring will consist of the following:  Visual assessment of tree health;  Monitoring of formal photo-monitoring sites;  Analysis of tree health data using graphing and basic statistics; and  Report the overall tree health of vegetation.

Monitoring will be conducted on a monthly basis before, during and for at least 12 months post- mining.

DMS-EP-10.7 18 July 2012 5 3.1 Vegetation Health Monitoring Methodology

The following equipment will be required to undertake the monthly vegetation health assessment for each of the five transects:  Aerial map of transect locations (refer to Figure 1);  Vegetation health monitoring field data sheets (DMS-EF46) (Refer to Attachment 1);  Tape measure;  Camera;  Compass;  GPS.  Cow tags;  Flagging tape;  Paint; and  Stakes. 3.2 Visual Assessment

Each individual tree for each transect will be tagged (a numbered cow tag held on with wire) for identification and tree characteristics will be measured in accordance with the guidelines established during the initial assessment to ensure consistency. These characteristics will include:  Diameter at breast height (DBH) - measured with a tape measure at approximately 1.3m from ground level around the trunk. If numerous trunks are present, typically the largest trunk is measured (not for all trees). DBH will only be measured quarterly.  Canopy vigour is ranked from 1 (poor) to 5 (excellent) according to the proportion of canopy that is alive;  Canopy density is recorded as the percentage of canopy observed compared to the 100% density possible;  Height is measured by approximation from ground level;  Presence of new growth is assessed by checking for the softer leaves at the apical ends of lower branches;  Stress is ranked as D (dead), VS (very stressed), S (stressed) or NS (not stressed) according to a combination of defoliation and leaf health measures;  Presence of leaf stress can usually only be obtained from lower branches which are able to be closely observed. Leaf stress is indicated by leaves showing signs of desiccation, chlorosis or dying at the tips; and  Flowering.

Additional notes will be taken for each tree to summarise whether they could be described as;  Healthy (health considered normal);  Having epicormic growth (new growth from main stems);  A small canopy (relative to the size of the tree);  Presence of insects or pathogens, defoliating (leaf shed evident by bare branches);  Dying (high level of defoliation to a critical point), or

DMS-EP-10.7 18 July 2012 6  Dead (no photosynthesizing leaves evident). In addition trees will be observed for signs of flowering (Yes/No). 3.3 Photopoints

Photopoints will be established for each transect (Figure 1) to allow a visual comparison of changes to the vegetation condition over the life of the project. Appropriate photopoints will be set up in the July 2012 round of monitoring. Photopoints will be chosen with consideration to access and best representation of canopy health. 3.4 Vegetation Health Analysis and Reporting

Trend graphs for overall tree health for each tree in the four transects will be created by combining a score for each of three parameters (canopy vigour, canopy density and water stress). It should be noted however that this is a summary developed for ease of displaying general tree health trends over time. The following criteria will be used:  A score from 0-5 will be used for canopy vigour;  Canopy density (%) will be converted to a score of 0-10; and  The level of water stress will be converted to a score of 0-6 (Dead=0, Very Stressed-Dead=1, Very Stressed=2, Very Stressed=3, Stressed=4, Stressed-Not Stressed=5 and Not Stressed=6).

Each tree will then receive a combined score out of a maximum possible score of 21. The overall tree health score will then be grouped into the following ‘health levels’:  Level 1: An overall score of 0-5 (i.e. trees in poor condition);  Level 2: An overall score of 6-10;  Level 3: An overall score of 11-15;  Level 4: An overall score of 16 to 18; and  Level 5: An overall score of 19-21 (i.e. trees in the healthiest condition).

Trend graphs of the overall tree health ratings will be reported and discussed in the AER. 3.5 Vegetation Health Trigger Values

Should any trees within the four transects show signs of decreasing health likely to be due to groundwater drawdown (i.e. comparison with control sites), contingency measures will be implemented. 3.6 Vegetation Health Contingency Measures

In the event that monitoring demonstrates adverse trends, in consultation with the DEC, the following actions will be implemented:  The sequence of mining may be altered to reduce drawdown impacts;  Short term cessation of activities until such time as conditions allow for recommencement (e.g. soil moisture recharge due to rainfall, or alternatively via irrigation); and  Artificial irrigation of the affected areas and/or modification of mining activities.

Flora and Vegetation Management Plan Dardanup Mine and Burekup West Doral Mineral Sands Pty Ltd

Methodology for the Baseline Vegetation Monitoring Program.

Scope Tree health monitoring consists of the following Scope of Work:

• Visual assessment of tree health;

• Analysis of tree health data using graphing and basic statistics;

• Monitoring of formal photo-monitoring sites;

• Report the overall tree health of remnant vegetation; and

• Provide recommendations with regard to future monitoring.

Timing

Monthly

Methodology Baseline vegetation monitoring sites have been established at ten sites. Seven sites were established in February 2009 (Sites 1-7). A control site was established in April 2009 (Site 8) outside of the worst case groundwater drawdown area. In November 2009 another monitoring site was established in a Groundwater Dependant Ecosystem (Site 9a and 9b) which is located adjacent to the proposed amendment area to the Burekup mine. In June 2010 a tenth monitoring site was established (Site 10) along Simpson Rd. Refer to Figure 5 for the location of the vegetation monitoring sites.

Each individual tree has been previously tagged for identification and tree characteristics were measured in accordance with the guidelines established during the initial assessment to ensure consistency. These characteristics included:

• Diameter at breast height (DBH) was measured at approximately 1.3m from ground level around the trunk. If numerous trunks were present, typically the largest trunk was measured (not for all trees);

• Canopy vigour was ranked from 1 (poor) to 5 (excellent) according to the proportion of canopy that was alive;

• Canopy density was recorded as the percentage of canopy observed compared to the 100% density possible;

• Height was measured by approximation from ground level;

• Presence of new growth was assessed by checking for the softer leaves at the apical ends of lower branches;

• Stress was ranked as D (dead), VS (very stressed), S (stressed) or NS (not stressed) according to a combination of defoliation and leaf health measures;

• Presence of leaf stress could only be obtained from lower branches which were able to be closely observed. Leaf stress was indicated by leaves showing signs of desiccation, chlorosis or dying at the tips; and

• Flowering.

Additional notes were taken on each tree to summarise whether they could be described as: healthy (health considered normal); having epicormic growth (new growth from main stems); a small canopy (relative to the size of the tree); presence of insects or pathogens, defoliating (leaf shed evident by bare branches); dying (high level of defoliation to a critical point) or dead (no photosynthesising leaves evident). In addition trees were observed for signs of flowering (Yes/No). Appendix F Burekup West Flora Species List

Background Information

Phytophthora is a microscopic, soil borne organism that attacks the roots and basal stem tissue of living plants. It is often referred to as a “fungus”. Phytophthora acts by stopping the movement of water and nutrients to the plant, causing root-rot and dieback.

Dieback caused by the root-rot fungus P. cinnamomi has been listed as a 'key threatening process' under the Commonwealth's Environment Protection and Biodiversity Conservation Act 1999 effective from 16 July 2000 (CALM 2004).

Any movement of soil and/or plant material has the potential to spread Phytophthora to new areas. The most common means of spread is through movement of infested soil and plant material by humans. However Phytophthora can also be spread by movement of water and animals.

Species that are highly susceptible to Phytophthora have no resistance and once infected rapidly die. These species are often used as indicator species, as they are generally the first to show symptoms of infection. In Western Australia these include Jarrah, Banksias, Grasstrees (Xanthorrhoea), Zamia Palms, Hibbertias, Dryandras and Hakeas. It has been estimated through trials that 49% of the State’s threatened flora species are susceptible to P. cinnamomi (CALM 2004).

When determining the presence of dieback other factors that could have caused plant death must also be discounted (such as fire, insects, flooding, drought, chemicals, other pathogens etc). Plant root and soil samples can be taken and tested to confirm field observations.

Once an area is infected with Phytophthora, eradication is not possible. However, well developed management plans can assist in containing the disease and preventing further spread to uninfected areas.

Dieback Objectives

Dieback will be managed with consideration to the following objectives 1. To contain and minimize the spread of Phytophthora within and surrounding the Doral site 2. To manage infected areas in such a way as to minimise the effect on the environment. 3. To protect uninfected areas and minimise the risk of them becoming infected.

Management of Dieback

At present the Dieback status of the western extension area is unknown. It is proposed that an investigation be undertaken by an appropriately qualified person to determine classification, ie infested, uninfested, uninterpretable, protectable and unprotectable. Areas on site should be mapped as low/medium or high risk zones. A preliminary discussion has been undertaken with DEC (SW Region) in regards to the likelihood of die-back occurring in the Dardanup-Burekup area. DEC advised that flat lying land (ie the western extension area) is likely to be considered ‘uninterpretable’.

If areas have been identified as requiring management, based on the risk classification, site specific procedures will be developed in consultation with DEC (with consideration to relevant State and Commonwealth policies). Should management be required, to reduce the risk of the spread of dieback, three key strategies should be employed: • modifying activities • controlling access • adopting hygiene procedures The following management strategies will be considered (amongst others) if management of Dieback is required: • Ensure risk status of the area is known. • Schedule work in low/moderate risk zones before high risk zones. • Restrict movement of people, vehicles and equipment. It may be necessary to quarantine areas, either permanently or temporarily (for example when the soil is moist). • On leaving high risk zones, ensure vehicles, machinery, equipment and footwear are free of mud, soil and plant material. • Travel only on designated roads and tracks. Avoid entering surrounding bushland. • Ensure all materials used, including gravel, are free of Phytophthora. If in doubt, have soil/gravel samples tested in the laboratory. • Do not remove any water, soil or plant material from a high risk zone. Restrict soil movement within this zone. Replace at original site if possible. • Disturb the soil as little as possible when controlling weeds • Ensure water and effluent does not drain towards vegetation. Avoid sites prone to flooding and ponding. • Provide hygiene stations as appropriate. • Erect signs as appropriate. • Educate staff as to the importance of Phytophthora and their role in preventing its spread.
