Re: Berwick Health and Education Precinct – Native Vegetation Assessment (excluding Southern Drain)

Project no. 23541 Dear Belinda,

Biosis Pty Ltd. was commissioned by the Victorian Planning Authority (VPA) to provide advice on the extent and condition of native vegetation within the Berwick Health and Education Precinct (BHEP), Berwick (Figure 1). This assessment must be read in conjunction with Appendix 3 to this report, Berwick Health and Education Precinct- Vegetation assessment - Southern Drain (Biosis Letter Report, 05/05/2015).

Methods

The assessment was undertaken on 18 November 2016 and a list of plant species observed was collected (#U00J5ZR1). This list will be submitted to the Department of Environment, Land, Water and Planning (DELWP) for incorporation into the Victorian Biodiversity Atlas. Planted species have not been recorded unless they are naturalised.

Native vegetation is defined in the Victoria Planning Provisions as 'plants that are indigenous to Victoria, including trees, shrubs, herbs and grasses' (Clause 72).

The Guidelines classify native vegetation into two categories (DEPI 2013):

• A remnant patch of native vegetation (measured in hectares) is either:

– An area of native vegetation, with or without trees, where at least 25 percent of the totalperennial understorey cover is native plants.

– An area with three or more indigenous canopy trees where the tree canopy cover is at least20 percent.

Remnant patch vegetation is classified into ecological vegetation classes (EVCs). An EVC contains one or more floristic (plant) communities, and represents a grouping of broadly similar environments. Definitions of EVCs and benchmarks (condition against which vegetation quality at the site can be compared) are determined by DELWP.

• A scattered tree is defined as (extent measured by number of trees):

– An indigenous canopy tree that does not form part of a remnant patch of native vegetation.

A canopy tree is a mature tree that is greater than three metres in height and is normally found in the upper layer of a vegetation type. Ecological vegetation class descriptions provide a list of the typical canopy species. A condition score and extent is applied to each scattered tree based on information provided by DELWP's NVIM.

Species nomenclature for flora follows the Flora Information System (2016).

Results:

Vegetation of the study area is not mapped as native vegetation according to DELWP's mapping (see the 2005 EVC layer in the Biodiversity Interactive Map 3.2), with the original vegetation (pre 1750) identified as a mosaic of Plains Grassland (EVC 132) and Plains Grassy Woodland (EVC 55) with low lying areas supporting a mosaic of Swampy Riparian Woodland (EVC 83) and Swamp Scrub (EVC 53). Small remnants of this mosaic are identified by DELWP along the Princes Freeway at the southern boundary of the study area.

The pre-1750 vegetation of this site would have varied throughout the study area according to topography and soil type. Typically, woodland vegetation types would have had an open canopy of River Red-gum Eucalyptus camaldulensis or Swamp Gum Eucalyptus ovata and Narrow-leaf Peppermint Eucalyptus radiata. The understorey typically consisted of shrubs including Black Wattle Acacia mearnsii, Blackwood Acacia melanoxylon, Swamp Paperbark Melaleuca ericifolia and Black Sheoak Allocasuarina littoralis that overtop a species-rich grassy and herbaceous ground layer. Grassland areas would have been dominated by native perennial grasses such as Kangaroo Grass Themda triandra and Wallaby-grass Rytidosperma spp., interspersed with a diversity of herbs. Low-lying areas would have formed seasonal wetlands dominated by semi-aquatic herbaceous vegetation like sedges (Carex spp. ) and rushes (Juncus spp.).

The vegetation throughout the study area is highly modified from its original condition and degraded due to the extensive land clearing that has occurred within Berwick and its surrounds. Overall, the condition of the vegetation is poor due to a lack of canopy trees, loss of native species diversity, and the presence of a high cover of weeds, including a number of noxious weeds such as Blackberry Rubus anglocandicans and Gorse Ulex europaeus (Appendix 1). Most of the study area comprises lawn areas with planted amenity vegetation within the Monash campus and destocked paddocks adjacent to the campus supporting exotic pasture (e.g. Toowoomba Canary Grass Phalaris aquatic and Ryegrass Lolium rigidum) and weeds. Two constructed hydrological features are also included in the study area: an unnamed drainage line draining into the southern drain and a farm dam, which is currently fenced, with access provided by Monash security.

Notwithstanding the above, the site inspection confirms the presence of four patches of native vegetation as defined above. These are mapped in Figure 2a and 2b and described below. These are referred to as Habitat Zones (HZ) and they cover a total area of 0.93 ha. Outside of these patches, native vegetation persists as scattered understorey trees such as Silver Wattle Acacia dealbata and Blackwood and Black Wattle (Figure 2b).

• HZ1. Plains Grassland. These patches are near a sports field and around the dam. They contain no canopy species or shrubs but the perennial component of the ground-layer vegetation includes native grasses consistent with Plains Grassland (Weeping Grass Microlena stipoides, Wallaby-grass and Blown Grass Lachnogrostis filiformis) so has been assessed as a treeless vegetation type. The characteristic herbs of this EVC are no longer present but some native herbs such as Willow Herb Epilobium hirtigerum, Loosetrife Lythrum hyssopifolia, Crane's Bill Geranium sp. and Cotton Fireweed Senecio quadridentatus persist. Weed species typical for the EVC are also found throughout the patch including Cat's Ear Hypochoeris radicata, Toowoomba Canary Grass Phalaris aquatica, Spear Thistle Cirsium vulgare and Ribwort Plantago lanceolata.


• HZ2. Plains Grassy Wetland. Habitat Zone 2 patch is a small constructed drainage channel that drains into the southern drain. The native vegetation of this patch was observed to largely consist of herbaceous semi-aquatic species including Knob sedge Carex inversa, rushes Juncus spp., Narrow-leaf Cumbungi Typha domingensis and Slender Knotweed Persicaria decipiens. Common Onion-orchid Microtis unifolia was also found. High weed cover was also present in the patch including Umbrella Sedge Cyperus eragrostis, Cocksfoot Dactylis glomerata, Toowoomba Canary Grass, Blue Pigroot Sisyrinchium iridifolium and Pampas Grass Cortaderia selloana. The vegetation was assessment as treeless vegetation and scattered wattles mapped near the patch were not included in the assessment.

• HZ3. Plains Grassy Woodland. Habitat Zone 3 is contiguous with the southern drain section previously assessed by Biosis but is separated from the drain by fencing. While none of the characteristic Plains Grassy Woodland canopy species were found in the patch, understorey trees such as Black Wattle and Blackwood and high native perennial ground-layer consistent with this EVC were still present. The quality of the ground-layer varied throughout the patch but in places was dominated by Spear Grass Austrostipa rudis with almost 100% cover. Other native perennial grass species observed were Kangaroo Grass, Weeping Grass and Common Tussock-grass Poa labillardieri. Some native herbs also persisted including Pale Flax-lily Dianella longifolia and Grassland Wood-sorrel Oxalis perennans. The ground-layer was degraded in places by the presence of noxious weeds such as Blackberry and Gorse and the invasion of pasture species from the adjoining paddock.

• HZ4. Plains Grassy Woodland. Habitat Zone 4 is formed by a mid-layer of Black Wattle consistent with remnants of a Plains Grassy Woodland understorey but the ground-layer and canopy trees of the EVC are no longer present. Instead, the ground-layer is mostly weed and pasture species and includes a high cover of noxious weeds (Blackberry and Gorse). These infestations smother other vegetation and prevent many other species from recolonising the site.

Condition and health of native vegetation

The extent of native vegetation patches was mapped within the study area (Figure 2) and the condition was assessed in relation to standard methods provided by DSE (2004). The condition of native vegetation was assessed using the DSE Vegetation Quality Assessment Sheet (DSE 2004) and pre-determined EVC benchmarks: http://www.dse.vic.gov.au/conservation-and-environment/ecological-vegetation-class-evc-benchmarks-by-bioregion. DELWP's Native Vegetation Information Management system was also used to determine vegetation extent and condition.

Native vegetation patches were assessed as remnants of the EVCs described above.

Habitat hectares

As noted above, for the purpose of determining vegetation condition, patches are termed ‘habitat zones’. Each EVC was assessed as a separate habitat zone. Some habitat zones consist of multiple patches of the same EVC with the same vegetation quality. Where there was a visually assessed difference in 2 or more habitat components, EVCs were divided into separate habitat zones as per DSE (2004). The condition score of the habitat zone is multiplied by the extent of the zone to give a value in Habitat hectares.

Scores allocated to each of the four habitat zones identified within the study area are outlined in Table 1. Total habitat hectares across all HZs is 0.148 as calculated below.

Vegetation Health

Native vegetation within the study area did not appear to be impacted by any obvious diseases or was otherwise impacted by any obvious insect attack which reduced or would otherwise lead to a conclusion that the vegetation present was in poor health. The two main wattle species present, Blackwood and Black Wattle, were present as a range of age cohorts and appeared to be present as naturally sustaining populations. Some scattered wattles appear to be reaching the end of their natural lifespans and are beginning to die off (senesce).

Implications of the Assessment

Any clearing of native vegetation within the study area may require a permit under the Planning and Environment Act 1987. Applications for the clearing of native vegetation are regulated under Victoria's Biodiversity Assessment Guidelines (DEPI 2013) (the Guidelines). DELWP classify most of the study area as Location A although parts of the study area boundary along Princes Freeway is identified as Location B and Location C.

If the study area is proposed to be impacted by development which would result in the clearing of native vegetation then it is likely that proposal would be assessed under the high risk pathway. This assessment includes relevant information for such an application.

Native vegetation patches are subject to offset requirements under a planning permit application, however, the total habitat hectares of the site is very low. Scattered understorey trees outside of patches would still be subject to a planning permit application should they need to be removed but offsets would not be required.

Conclusion We assessed four habitat zones to be patches of native vegetation as defined under Victoria's Biodiversity Assessment Guidelines. Remaining woody species that formed these remnants appeared to be healthy and were recruiting. The presence of noxious weeds, generally high weed cover and lack of canopy trees in treed EVCs reduced the condition of most of the native vegetation.

Outside of native patches, native vegetation was present only as scattered understorey trees in various stages from seedlings to aging. Remaining areas were paddocks and lawns of mostly introduced species.

The patches of native vegetation identified occupy a total of 0.93 ha. This native vegetation is considered to be degraded in condition and was assessed to have low habitat scores between 14/100 and 37/100. The vegetation therefore represents a total of 0.148 habitat hectares. NB. This is additional to the 0.13 ha identified in the previous report to make a total of 0.278 habitat hectares for the Berwick HEP.

Clearing of native vegetation patches and understorey trees would require a permit under the Planning and Environment Act and it is likely this application would be required to satisfy the information requirements defined under the high risk-based pathway defined by the Guidelines. This report provides the relevant data for any such application.

Re: Berwick Health and Education Precinct- Vegetation assessment - Southern Drain Our Ref job # 19994

Dear Anna,

Biosis Pty Ltd. was commissioned by the Metropolitan Planning Authority to undertake a survey of the

health and condition of the vegetation in the drainage line in the southern section of the Berwick Health and

Education Precinct, 100 Clyde Road, Berwick (Figure 1).

Methods

The survey was undertaken on 24 April 2015 and a list of plant species observed was collected (#T25562).

This list will be submitted to the Department of Environment, Land, Water and Planning (DELWP) for

incorporation into the Victorian Biodiversity Atlas. Planted species have not been recorded unless they are

naturalised.

Native vegetation is defined in the Victoria Planning Provisions as 'plants that are indigenous to Victoria,

including trees, shrubs, herbs and grasses' (Clause 72).

The Guidelines classify native vegetation into two categories (DEPI 2013):

A remnant patch of native vegetation (measured in hectares) is either:

– An area of native vegetation, with or without trees, where at least 25 percent of the total

perennial understorey cover is native plants.

– An area with three or more indigenous canopy trees where the tree canopy cover is at least

20 percent.

Remnant patch vegetation is classified into ecological vegetation classes (EVCs). An EVC contains one or

more floristic (plant) communities, and represents a grouping of broadly similar environments. Definitions

of EVCs and benchmarks (condition against which vegetation quality at the site can be compared) are

determined by DELWP.

A scattered tree is defined as (extent measured by number of trees):

– An indigenous canopy tree that does not form part of a remnant patch of native vegetation.

Figure 1: Location of the Study Area - Berwick, Victoria


A canopy tree is a mature tree that is greater than three metres in height and is normally found in the upper

layer of a vegetation type. Ecological vegetation class descriptions provide a list of the typical canopy

species. A condition score and extent is applied to each scattered tree based on information provided by

DELWP's NVIM.

Species nomenclature for flora follows the Flora Information System (FIS 2014 edition).

Results:

Vegetation along the southern drain is not mapped (2005 EVC layer) as native vegetation according to

DELWP mapping (see Biodiversity Interactive Map 3.2), with the original vegetation (pre 1750) identified as a

mosaic of Plains Grassland (EVC 132) and Plains Grassy Woodland (EVC 55). Small remnants of this mosaic

are identified by DELWP along the Princes Freeway in close proximity to the drain.

The pre-1750 vegetation of this site is described as an open eucalypt woodland with a canopy of River Red-

gum Eucalyptus camaldulensis and Gippsland Red-gum Eucalyptus tereticornis. The understorey typically

consists of shrubs including Black wattle Acacia mearnsii, Blackwood Acacia melanoxylon and Black Sheoak

Allocasuarina littoralis that overtop a species-rich grassy and herbaceous ground layer.

The vegetation along the drain is highly modified and degraded due to the extensive land clearing that has

occurred within Berwick and surrounds. The drain itself is not a natural drainage line but an engineered

feature that drains directly into the Berwick town drain to the west of the study area.

Overall, the condition of the vegetation along the drain is poor with a high cover of a number of noxious

weeds (Appendix 1). Infestations of Blackberry Rubus fruticosus spp. agg, Wandering Jew Tradescantia

fluminensis and Flax-leaf Broom Genista linifolia are extensive (Plates 1, 2 & 3). These infestations smother

other vegetation and prevent many other species from recolonising the site.

Notwithstanding the above, the site inspection confirms the presence of small remnant patches of native

vegetation along the drain (Figure 2). This includes areas dominated by shrubs and understorey trees such

as Blackwood Acacia melanoxylon and Black Wattle Acacia mearnsii, narrow bands of aquatic species such as

Narrow-leaf Cumbungi Typha domingensis and Slender Knotweed Persicaria decipiens and small patches of

indigenous grasses including Veined Spear-grass Austrostipa rudis, Kangaroo Grass Themeda triandra,

Weeping Grass Microlaena stipoides, Mat Grass Hemarthria uncinata and wallaby-grass species Rytidosperma

spp as well as other herbs.

The vegetation along the slopes of the drain is devoid of any native eucalypts that would normally

characterise areas of Plains Grassy Woodland. Rather, the remnant patches of native vegetation are

formed by the presence of understorey trees including Blackwood and Black wattle (Plate 4). Scattered

occurrences of other shrubs included Hedge wattle Acacia paradoxa, Prickly Tea-tree Leptospermum

continentale and Drooping Cassinia Cassinia arcuata. Indigenous groundcover species occur as scattered

individuals or small species poor patches.

The eastern end of the study area lacks a native ground layer and is dominated by weedy pasture grasses

such as Couch Cynodon dactylon var. dactylon and Kikuyu Cenchrus clandestinus (Plate 5). However, a small

remnant native grassland is present along the northern bank at the western end of the study an area. This

grassland is dominated by Kangaroo Grass and Veined Spear-grass Austrostipa rudis subsp. rudis (Plate 6).

Isolated occurrences of herbaceous species that characterise Plains Grassland are also recorded. These

include Sheep's Burr Acaena echinata, Pale Flax-lily Dianella longifolia, Kidney Weed Dichondra repens and

fireweeds Senecio spp.

Study area

Native vegetation


The drainage channel and association wetted perimeter also supported patches of native species (Plate 7).

Patches of Slender Knotweed Persicaria decipiens, Narrow-leaf Cumbungi Typha domingensis and Common

Spike-sedge Eleocharis acuta were located along the drain and extended onto the bank. Isolated herbs in

these wetter areas include Shrubby Fireweed Senecio minimus and Crane's Bill Geranium sp. 14 (Plate 8).

These areas were incorporated into patches of vegetation identified as remnants of Plains Grassy Woodland

as the cover of these wetland plants was typically overshadowed by wattles.

Condition and health of native vegetation

The extent of native vegetation patches was mapped within the study area (Figure 2) and the condition was

assessed in relation to standard methods provided by DSE (2004). The condition of native vegetation was

assessed using the DSE Vegetation Quality Assessment Sheet (DSE 2004) and pre-determined EVC

benchmarks: http://www.dse.vic.gov.au/conservation-and-environment/ecological-vegetation-class-evc-

benchmarks-by-bioregion. DELWP's Native Vegetation Information Management system was also used to

determine vegetation extent and condition.

All native vegetation patches were assessed as remnants of Plains Grassy Woodland.

Habitat hectares

Patches are termed ‘habitat zones’. Due to the relatively degraded nature of the native vegetation present

all patches of native vegetation were identified as a single habitat zone. The condition score of the habitat

zone is multiplied by the extent of the zone to give a value in Habitat hectares.

Scores allocated to the habitat zone identified within the study area are outlined in Table 1.

Vegetation Health

Native vegetation within the study area did not appear to be impacted by any obvious diseases or was

otherwise impacted by any obvious insect attack which reduced or would otherwise lead to a conclusion

that the vegetation present was in poor health. The two main wattle species present, Blackwood and Black

Wattle, were present as a range of age cohorts and appeared to be present as a naturally sustaining

population (Plates 1, 4, 5 & 6).

Implications of the Assessment

Any clearing of native vegetation within the study area may require a permit under the Planning and

Environment Act 1988. Applications for the clearing of native vegetation are regulated under Victoria's

Biodiversity Assessment Guidelines (DEPI 2013) (the Guidelines). DELWP classify most of the study area as

Location A although the western end of the drain is identified as Location C.

If the study area is proposed to be impacted by development which would result in the clearing of native

vegetation then it is likely that proposal would be assessed under the high risk pathway. This assessment

includes relevant information for such an application.

Conclusion

The study area supports patches of native vegetation as defined under Victoria's Biodiversity Assessment

Guidelines. Many of the species which formed these remnants appeared to be healthy and were actively

recruiting.

The patches of native vegetation identified occupy a total of 0.526 ha. This native vegetation is considered

to be degraded in condition and was assessed to have a relatively low habitat score (24/100). The

vegetation therefore represents a total of 0.13 habitat hectares.

Clearing of this vegetation would require a permit under the Planning and Environment Act and would likely

be required to satisfy the information requirements defined under the high risk-based pathway defined by

the Guidelines. This report provided the relevant data for any such application.
