Executive Summary

The following bushfire assessment for 455 Mount Rumney Road, Mount Rumney has been carried out as part of a building application for a new dwelling.

The Bushfire Prone Area of the Clarence Interim Planning Scheme 2015 overlay indicates the site is within a bushfire prone area so an assessment of the land was undertaken to determine the applicable Bushfire Attack Level (BAL) as defined under Construction of buildings in bushfire-prone areas, AS3959-2009.

Under the ‘Director’s Determination – Requirements for Building in a Bushfire-Prone Area (v2.1)’ Building Act 2016, a Bushfire Attack Level (BAL) assessment for a new dwelling is required at the building application stage. This report includes the Bushfire Hazard Management Plan (BHMP) which is a requirement of the Building Regulations 2014.

The assessment has been undertaken in consideration of the Clarence Interim Planning Scheme 2015 and the Construction of Buildings in Bushfire-Prone Areas, AS3959-2009.

The site is located on Guy Fawkes Hill which is generally cleared on top (grassland) with woodland on the slopes in all directions. The slopes drop away from the building site at greater than 20o to the east, south and west. To the north the slope is >10-15o. The understorey of the woodland is dominated by native and exotic grasses.

In accordance with the ‘Director’s Determination – Requirements for Building in a Bushfire-Prone Area (v2.1)’, the dwelling should be built to BAL 29 with a hazard management area (HMA) which achieves BAL 29 separation distances. Due to the shape of the lot, the slope and the proximity of woodland, a BAL 29 solution cannot be achieved through reliance on the Method 1 BAL assessment. In its place, a BAL 29 solution can be achieved with performance solutions using Method 2 calculations (AS 3959-2009).

In the absence of being able to achieve BAL 29 based on Deemed-to-satisfy requirements, the Tasmania Fire Service (TFS) assessed the property using Method 2 (AS 3959-2009) and the results are reported here.

As a result of the assessment and written advice by TFS (correspondence dated 21/02/2018), the dwelling can be built to BAL 29 and the following performance criteria must be met:

• Minimum separation distances required between the proposed habitable building and classified vegetation are: 38 m to the north, east, south and west (woodland on >20o). These distances are the basis of the minimum HMA designated around the perimeter of the new dwelling as determined by TFS using Method 2 calculations AS3959-2009 and as indicated in Table 1 and the BHMP (Attachment 1);

• The HMA to the east of the proposed dwelling relies on management of vegetation on the adjoining land. A formal agreement such as a Part V Agreement or easement is to be entering into with the adjoining land holder to allow for ongoing maintenance of the HMA.

• New dwelling will need to comply with construction standards for BAL 29 as defined in AS3959-2009 (Sections 3 and 7) which will ensure a suitably defendable building;



• Static fire-fighting water must be provided to specifications described in Table 4.3B of the ‘Director’s Determination – Requirements for Building in a Bushfire-Prone Area’; and

• Access is greater than 30 m and therefore must comply with design and construction specifications as per Table 4.2 Element B and D of the ‘Director’s Determination - Requirements for Building in Bushfire-Prone Areas’.

Subject to implementing the performance the proposed BHMP, the proposed development will meet the Performance Requirements of the Director’s Determination.

Disclaimer The assessor has taken all reasonable steps to ensure that the information provided in this assessment is accurate and reflects the conditions on and around the site and allotment on the date of this assessment. Whilst measures outlined in this report are designed to reduce the bushfire risk to the dwelling, due to the unpredictable nature of wildfires and impacts of extreme weather conditions the survival of the structure during a fire event cannot be guaranteed.



1. Introduction

The following bushfire assessment for 455 Mount Rumney Road, Mount Rumney (Title Reference C.T. 118311/3) has been carried out to accompany a residential building application. The proposed dwelling is within a bushfire-prone area as indicated by the Bushfire Prone Area overlay (Clarence Interim Planning Scheme 2015). Due to the steep slopes (>20o) under woodland in all directions, the development was referred to Tasmania Fire Service (TFS) for advice on the applicable BAL and to be assessed on performance criteria.

This report includes: the TFS assessment of the BAL; and the performance criteria for the new dwelling to be incorporated in the Bushfire Hazard Management Plan (BHMP). As the site is unable to comply with Deemed-to-Satisfy HMA requirements as per the ‘Director’s Determination – Requirements for Building in a Bushfire-Prone Area v2.1’ Building Act 2016. TFS has applied the BAL assessment Method 2 calculations to determine performance requirements that enable the proposed dwelling to achieve BAL 29 building solution.

Date of Assessment: 4/01/2018

Assessment Number: ED1803

1.2 Site Description

The site is a Designated Communications Facility comprising a 2.5 ha lot located at 455 Mount Rumney Road on the summit of Guy Fawkes Hill at approximately 350 m above sea level with an underlying dolerite geology. In addition, the site includes part of the east facing slope of 467 Mount Rumney Road because 455 Mount Rumney Road depends on it for its hazard management area. The aspect is predominantly south, with views over: South Arm, Frederick Henry Bay to the east, and the Derwent River to the west, (Figure 1).



The top of the hill and the northern portion of the lot is predominantly cleared for communication towers. On the southern slope of the hill, some clearing has occurred for the communications lines. The hill is otherwise covered by dry Eucalypt woodland with a grassy understorey (Figure 2 and Photos 1 to 4, Appendix 1).

Access to the site is from the end of Mount Rumney Road via a 500 m long access track with passing bays on the west boundary of the Mount Rumney Conservation Area to a cul-de-sac. This (private) gravel road provides access to six other lots off the cul-de-sac, on the south side of Mount Rumney Conservation Area. From the cul-de-sac, an additional 400 m track accesses four lots (455, 463, 467 and 491 Mount Rumney Road). The first 200 m through 491 are paved beyond which it is a rough track. 463 and 455 Mount Rumney Road are a Designated Communications Facility, 491 Mount Rumney Road is a developed residence with landscaping and 467 Mount Rumney Road is partially cleared in preparation for development and depends on access via 491 or 455 rights-of-way (Refer to Appendix 1 for photos).

Note there is a 7m wide right-of-way attached to the Title of 455 Mount Rumney Road (Attachment 2). However, as stated above, the existing access to 455 and 467 is via a shared access across 491 Mount Rumney Road.

The lot has power but no reticulated water nearby.

Under the Clarence Interim Planning Scheme 2015 (CIPS 2015), the property is zoned Environmental Living (Private freehold tenure) with Utilities zone for the communications tower (Authority freehold tenure. Surrounding land includes: Open Space zone for Mount Rumney Conservation Area 375 m to the north (Conservation Area tenure); a strip of Public Recreation Space 150 m to the southeast (Local Government tenure); and Rural zoning 100 m downslope to the west.

The lot is overlaid by a: Biodiversity Protection Area with high conservation values; Bushfire-Prone Area, and Landslide Hazard Area with low risk exists through the middle of the lot. These areas were considered in the selection of the proposed house site. Due to the existing clearing, structures and confined nature of the lot, the proposed dwelling location on the top of the hill is the reasonable option. However, a dwelling in this location is at a high risk from bushfire and cannot achieve the BAL 29 acceptable solutions due to slope. Therefore, performance criteria approved by TFS and established and maintained by the owner are required.

1.3 Building Proposal

The proposal is for the construction of a 1-story caretaker’s cottage (New Class 1 building). The dwelling is to be located on the top of Guy Fawkes Hill in the central-eastern portion of the lot to be accessed from an existing track that is approx. 900 m long from the end of Mount Rumney Road.

The bushfire assessment is based on the site plan and the Folio Plan provided by Astral Communications Towers (Appendix 2).

2. Bushfire Attack Level Assessment The following is a summary of the bushfire risk at the property.

Bushfire Hazard: Slope and woodland vegetation Bushfire Attack Mechanisms: Radiant heat, ember attack, wind, direct flame and smoke Bushfire Threat Direction: The highest bushfire threat to the proposed residence is from the woodland vegetation located downslope from the northeast and north. The fire history in the area indicates the lot burned during the 1966-67 fires. More recent bushfires occurred in the Meehan Range during the 2007-08 and 2015-16 fire seasons approximately 2 km and 3 km to the southwest, respectively. Fire Danger Index: FDI 50 (this index applies across Tasmania). Vegetation & Slope: The slope under woodland vegetation is downslope in all directions: >10-15o to the north; and >20o downslope in all other directions. The slope under the woodland contributes to the elevated risk of bushfire gaining speed from these directions. Significant Natural Values: There is an eagles nest recorded to the southeast and records of Wedge-tailed eagles and swift parrots exist within 500 m of the lot but there are no threatened flora species recorded on the property (Natural Values Atlas 2018). The vegetation on the site is mapped as DPU – Dry Eucalyptus pulchella forest and woodland across the northeast and southern portions of the property. The remainder of the lot is mapped as Eucalyptus viminalis grassy forest and woodland (DVG). Neither of these communities are protected under Schedule 3A of the Nature Conservation Act 2002. There are scattered mature blue gums which provide potential foraging habitat for swift parrot. Infestations of serrate tussock occur on the site. This is a declared weed under the Tasmanian Weed Management Act 1999 and listed as a weed of national significance (WoNS).

Refer to Table 1 for the summary of the BAL Assessment, Appendix 3 for the Method 2 calculations and Figure 2 for the BAL Site Assessment Area.

3. Bushfire Protection Measures

The site is within a defined Bushfire-Prone Area as it is within the overlay under the Clarence Interim Planning Scheme 2015. As such, to construct a new building on a lot not provided with a BAL at the time of subdivision, minimum building standards must be met. The applicable Deemed-to-Satisfy standards are set out under clause 4 and Tables 4.1 to 4.4 of the ‘Director’s Determination – Requirements for Building in a Bushfire-Prone Area v2.1’.

Clause 4.4 and Element B of Table 4.4 require ‘hazard management areas’ with widths equal to or greater than the separation distances required for BAL 29 as per Table 2.4.4 of Construction of buildings in bushfire-prone areas AS3959-2009 and managed as per a Bushfire Hazard Management Plan.

In this case, where BAL FZ is assessed and the slopes under Woodland are greater than 20o, Deemed-to-Satisfy HMA requirements as outlined in Table 2, 4.4 below, cannot be satisfied. As such, the proposal will satisfy the Performance Requirements of the Director’s Determination using a Performance Solution in combination with Deemed-to-Satisfy requirements for construction, access and water supply. TFS provided technical advice using AS 3959-2009 Method 2 (detailed method for determining the BAL) to inform the preparation of the Performance Solution for appropriate separation distance from bushfire hazard as indicated in Table 2 by Clause S.3, 1d.

3.4 Hazard Management Areas (Clause 4.4)

Defined under the ‘Director’s Determination – Requirements for Building in a Bushfire-Prone Area v2.1’, a HMA is ‘the area, between a habitable building or building area and the bushfire-prone vegetation, which provides access to a fire front for fire-fighting, which is maintained in a minimal fuel condition and in which there are no other hazards present which will significantly contribute to the spread of a bushfire’.

Further information on the maintenance of the equivalent ‘defendable space’ are also provided in the Tasmania Fire Service (TFS) document Guidelines for Development in Bushfire-Prone Areas of Tasmania (2005); and Building for Bushfire Siting and Design.



Requirements

The HMA provides a cleared space (separation distance) between the building and the bushfire hazard. Any vegetation in this area needs to be strategically modified and then maintained in a low fuel state to protect buildings from direct flame contact and intense radiant heat thereby allowing them to be defended from lower intensity bushfires. Fine fuel loads must be minimal to: reduce the quantity of windborne sparks and embers reaching buildings; to reduce the radiant heat at the building; and to halt or check direct flame attack.

Compliance with Deemed-to-Satisfy clause 4.4 requires a Method 1 assessment which could not be undertaken due to the excessive slope (greater than 20o). Therefore, compliance with Deemed-to-Satisfy requirements for HMA is not possible. In its place a Performance Solution is required to satisfy clause 3 (1d). The HMA performance requirements were determined by TFS using Method 2 calculations – detailed method for determining BAL, AS 3959-2009 (refer to Appendix 3 of this report).

Council will include a Part V Agreement, or equivalent mechanism, as a condition on the planning permit to: enable the HMA establishment and maintenance on the neighbouring property: and ensure the formal arrangement is in-place prior to occupancy i.e. sign-off by the building surveyor.

Current Conditions

The proposed building site has been cleared and some clearing of the HMA has occurred.

The HMA encroaches onto the adjoining property to the east (467 Mount Rumney Road). The owner of 467 Mount Rumney Road (Lot 2 C.T. 118311/3) has indicated that formal agreement to establish and maintain the HMA on this property will be granted, refer to Appendix 4. However, as a condition of the SD-2007/80 there is already be a Part V Agreement in place that addresses bushfire management, this should be confirmed by Council during the building application stage (Appendix 4). Compliance

The Performance Solution requires separation distances of 38 m are established and maintained as per the BHMP (Attachment 1).

A HMA with 38 m separation distances will comply with BAL 29 and is to be established around the proposed new dwelling as per Table 1 and the BHMP (Attachment 1) and the following:

• HMA to be established for minimum distance of 38 m to the north, east, south and west.

• A Part V Agreement (or equivalent mechanism) must be established with 467 Mount Rumney Road, to ensure HMA separation distances are achieved to the east. Refer to Appendix 4 for the letter of agreement in-principle signed by the owner of 467 Mount Rumney Road and the existing Part V agreement on C.T. 118311/3.

• Mature eucalypt trees, south of the building area, be retained provided they are at least 10 m from the dwelling and subject to: ground cover being managed to <100 mm height; tree branches within 4 m of the ground being removed; and immature eucalypt trees being removed. The existing blue gums should be given priority for retention as



they provide potential foraging habitat for swift parrots. Small clumps of established trees and/or shrubs may act to trap embers and reduce wind speeds.

• Small clumps of shrubs can be planted within the HMA provided they are further than 10 m from the dwelling and there is separation between clusters (min 10 m).

• Non-combustible elements including driveways, paths and short cropped lawns are recommended within the HMA.

• Fine fuels (leaves bark, twigs) should be removed from the ground periodically (pre-fire season) and all grasses or pastures must be kept short (<100 mm).

• Fuels are reduced sufficiently, and other hazards are removed such that the fuels and other hazards do not significantly contribute to the bushfire attack.

HMA Maintenance

The HMA must be maintained in a minimal fuel state at all times for bushfire protection mechanisms to be effective. An annual inspection and maintenance of the HMA should be conducted prior to the bushfire season. All grasses or pastures must be kept short (<100 mm) and any flammable fine fuels at ground level such as leaves, litter and wood piles must be suitably managed. Small clumps of established trees and/or shrubs may be maintained to trap embers and reduce wind speeds. In addition, fire protection measures such as fire pumps and sprinkler systems must be tested to ensure functionality.

The Part V Agreement (or equivalent mechanism) with the adjoining land owner (467 Mount Rumney Road) will allow for maintenance of the HMA on the adjoining land. Refer to Appendix 4 for a letter of agreement-in-principle.

4. Conclusions

The assessment of the bushfire risk of a proposed new dwelling at 455 Mount Rumney Road, indicates that it is able to achieve the ‘Director’s Determination – Requirements for Building in a Bushfire-Prone Area v2.1’ for a BAL 29 rating provided compliance with the Director’s Determination is achieved by means of a Performance Solution. The elements of the Performance Requirements relating to access, water and construction will be achieved through Deemed-to-Satisfy requirements. The elements relating to the hazard management plan will be achieved by means of a performance-based approach utilising Method 2 of AS3959. Compliance is dependent on the following:

• A minimum 38 m separation distance from the new habitable building to classified vegetation (Woodland) to the north, east, south and west is the basis of the minimum HMA designated around the perimeter of the proposed dwelling as defined by the performance requirements indicated in Table 1 (above) and the BHMP (Attachment 1). Ongoing management of the woodland vegetation must be undertaken to maintain these separation distances.

• Building work must meet Deemed-to-Satisfy requirements as defined by Section 4.1 and Table 4.1 of the ‘Director’s Determination – Requirements for Building in Bushfire Prone Areas v2.1’ and for BAL 29 as per AS3959-2009 (Sections 3 and 7).



• Provision of access to meet specified requirements for the design and construction as it is greater than 30 m and provides access to more than three properties (Section 4.2 and Elements B and D of Table 4.2 – Standards for Property Access).

• Provision of static water supply to meet the requirements of Section 4.3 and Table 4.3B - Static Water Supply for Fire-fighting.

• A Part V Agreement (or equivalent mechanism) on the title of 467 Mount Rumney Road will be established to ensure the formation and ongoing maintenance of the required HMA for the dwelling on 455 Mount Rumney Road.

5. Recommendations

The recommendation is to adopt the BHMP as per Attachment 1.

5.1 Limitations of Plan

The bushfire protection measures outlined in this plan are based on a Fire Danger Index of 50 (FDI 50) which relates to a fire danger rating of ‘very high’. Defending the property or sheltering within a structure constructed to AS3959-2009 on days when the fire danger rating is greater than 50 (i.e. ‘severe’ or higher) is not recommended.

Due to the unpredictable nature of bushfire behaviour and the impacts of extreme weather no structure built in a bushfire-prone area can be guaranteed to survive a bushfire. The safest option in the event of a bushfire is to leave the area early and seek shelter in a safe location.

NATURAL VALUES REPORT IN RELATION TO A PROPOSED DWELLING AT 455 MOUNT

RUMNEY RD, MOUNT RUMNEY, TASMANIA

Prepared by Philip Cullen

11 Salvator Rd., West Hobart, Tasmania.

Ph 0428108434

26/7/2017

Summary

The following report is a Natural Values Assessment for a proposed dwelling at 455 Mount Rumney

Road, Mount Rumney, Tasmania. The site of the proposed dwelling has been leveled and most of

the topsoil has been removed during the construction of the telecommunications towers and road

access in the past. The area has been recolonized by commonly occurring native flora species and

weeds. No flora or fauna or vegetation communities of conservation significance have been

recorded within the area to be impacted by the proposed development, the footprint of the dwelling

and a 10 m buffer zone. Swift Parrots have been recorded within 500 m of the proposed

development and it is likely that this species uses immediately surrounding forest for foraging and

potentially for nesting habitat. Building design should incorporate features to reduce the risk of

bird collisions. One raptor nest has been recorded within 500 m of the study area. No features of

geoconservation significance have been recorded within the study area or within 1 km of the site.

One Tasmania Management Act Weed has been found within 500 metres of the proposed dwelling

but the species was not recorded in the study area.

Proposed works The development proposal is for the construction of a new dwelling. The works are situated on a 2.5 ha

parcel of private land at 455 Mount Rumney Road, Tasmania, 7170 (See Figures 1, 2, and 3). There are

some telecommunications towers on the site.

Purpose and scope of this assessment The scope of works for this assessment were to:

Carry out a natural values assessment from on-line and other published sources, as well as from

field inspection, of the proposed developments.

Identify flora and fauna species and plant communities of conservation significance that may be

impacted by the proposed developments.

Identify other botanical issues such as the spread of noxious weeds.

Identify any geoheritage features that will be impacted by the proposal.

Qualification to provide expert advice Philip Cullen is a botanist, biogeographer and geomorphologist with a Masters degree in biogeography

who has worked for universities, local and State Government, Parks and the private sector. He has been

working as a consultant, in Tasmania and elsewhere in Australia, for the past 27 years.

Biogeography and Physiography The study area is located in the Clarence Shire, in the South East Bioregion in south eastern Tasmania.

The site of the proposed development is at Guy Fawkes Hill. This feature is located on a southern spur of

Mt Rumney in the Meehan Range. Topography is steep, with slopes up to and over 20 degrees. The

bedrock at the site is Jurassic dolerite with some indication of minor remnants of Triassic Sandstone on

top of the dolerite sill. Soils are shallow and very rocky. It appears that most of the topsoil has been

removed from the site of the proposed dwelling during the construction of the telecommunications towers

and road access. Native vegetation at the site is dry schlerophyll forest.

Definitions

Study Area: that part of 455 Mount Rumney Road, Tasmania, 7170. Title reference 1549471/1, PID

2910702, being 2.5 ha in area that will be impacted by the proposed building developments. This

includes the building footprint and a surrounding 10 m buffer zone.

Project locality: the area within 5 kilometres of the study area. This is consistent with the extent of

database searches.

Nomenclature Common and Scientific names follow Buchanan, A. M. (2014). Vegetation community names follow

(Kitchener and Harris 2014).

Desktop Assessment A number of databases were interrogated to compile a species list for the study area, the area and extent

of vegetation communities at the site and species and vegetation communities of conservation

significance within 5 kilometres of the study area.

Matters of national environmental significance

The Protected Matters Search Tool (Department of Environment 2013) was used to identify species

and vegetation communities protected under the EPBC Act 1999), known to occur or likely to

occur within 5 kilometres of the study area.

Flora, fauna and vegetation rare or threatened in Tasmania

The Natural Values Atlas (Natural Values Atlas: Authoritative, comprehensive information on

Tasmania's natural values Version 3.3.0.10) was searched for records of rare or threatened species

and plant communities at the study area and within 5 km.

Geoheritage

The Natural Values Atlas (as above) was searched for geoheritage features that could be impacted

by the proposal.

Field Assessment The field assessment was carried out on the 10/04/2017. The assessment concentrated on the area to be

impacted by the proposed development and a 10 m buffer zone around the construction site. A detailed

search of this area was completed to identify the plant species present. Adjacent forest was surveyed to

determine the TASVEG forest type, the dominant Eucalypt species, and the presence of hollow bearing

(old-growth) trees and raptor nests. At the time of the survey it was not possible to accurately identify

many of the grass and herb species present as they were not in flower. In addition some annual species

and geophytes many not have been evident at the time of the survey.

Results - Desk top assessment

Matters of National significance

a) Vegetation

There are 3 nationally listed threatened ecological communities known to occur or likely to occur within 5

km of the study area. Two of these are terrestrial communities, sub-tropical or temperate saltmarsh and

Lowland Native Grasslands of Tasmania. Only the later community has the potential to occur in the study

area. It does not occur here.

b) Flora - matters of national environmental significance

There are 8 nationally listed flora species that may occur within 5 km of the study area. These species are

considered to have the potential to occur in the study area (Table 1). No populations of these species were

found in the study area during the assessment. It should also be noted that the proposed building

developments will only impact on a highly modified area.

d) Wetlands

No nationally significant wetlands occur within 5 km of the study area. The study area lies within 10 km

of the RAMSAR wetland Pitt Water-Orielton Lagoon. However, the study area is not part of the

catchment of this important wetland.

Matters of State significance

a) Vegetation

TASVEG 3 maps 2 threatened vegetation communities as occurring within 1000 m of the study area:

Eucalyptus globulus dry forest and woodland (DGL) and Eucalyptus tenuiramis forest and woodland on

sediments (DTO). TASVEG maps 2 communities, Eucalyptus pulchella forest (DPU) and Grassy

Eucalyptus viminalis forest (DVG), as occurring in the study area. Neither of these communities were

recorded in the study area. The vegetation at the site of the proposed development is Eucalyptus globulus

dry forest and woodland (DGL). This vegetation community is listed as threatened in Tasmania (TNVC

2014) and is a priority for conservation. Eucalyptus tenuiramis forest and woodland on sediments (DTO)

was not recorded on the study area as the area is comprised of dolerite and associated soils.

b) Flora

Seven flora species, listed as vulnerable or endangered under the Threatened Species Protection Act 1995,

with the potential to occur in the study area have been recorded within 5 km. None of these where

recorded in the study area (Table 3). The study area has been cleared and heavily modified in the past.

Results-Field Assessment a) Vegetation Communities

One Tasveg community, Eucalyptus globulus dry forest and woodland (DGL) was recorded in the study

area. This community is listed as a priority for conservation in the bioregion and in Tasmania. The

proposed building developments will not impact on areas of Eucalyptus globulus dry forest and woodland

(DGL). The study area has been cleared in the past and is now recolonized by commonly occurring

native species and weeds (see Table 5). b) Flora.

Table 5 lists the flora found in the study during the field assessment No vulnerable rare or threatened

species where recorded in the study area.

Note: VRoTs = vulnerable, rare or threatened species, Origin: i=introduced species

b) Fauna.

No populations or signs (tracks, scats, burrows, etc) of vulnerable, rare or threatened species were found

in the study area during the assessment.

The Swift Parrot (Lathamus discolor) has been recorded within 500 m of the study area. A number of

mature Blue Gums (Eucalyptus globulus) which can provide prime foraging for Swift Parrots are found

immediately adjacent to the study area. No nesting hollows where recorded in these trees. Old-growth

Eucalyptus individuals with the potential to provide nesting hollows occur in forest surrounding the study

area. Swift Parrots were not recorded during the field survey, but the species, which over-winters on

mainland Australia, would not be expected at this time.

Given that Swift Parrots have been recorded nearby, and there is suitable foraging and nesting

habitat in adjacent forest vegetation, it is recommended that building design features should

include measures to reduce the risk of bird collisions (see Pfennigwerth 2008).

Geoheritage. No geoconservation sights are located within 1 km of the study area.

Weed management/Control Nassella trichotoma, serrated tussock has been recorded within 500 metres of the study area. This weed

species is listed under the Tasmania Management Act. The species was not recorded in the study area.

Tree removal

No trees will have to be removed to construct the proposed dwelling. No logs or stumps or other habitat

features occur within the foot print of the proposed dwelling.

Concluding comments The proposed dwelling is located on an area that has been highly modified in the past by clearing and

earthworks, including the removal of topsoil.

No flora or fauna or vegetation communities of conservation significance have been recorded within the

study area. The study area is surrounded by Eucalyptus globulus dry forest and woodland (DGL). This

community is threatened in Tasmania and here it is habitat for the nationally endangered Swift Parrot

(Lathamus discolor). Building design should incorporate features to reduce the risk if bird collisions on

windows. Tall chain mesh fences should not be installed at the site. One raptor nests has been recorded

within 500 m of the study area. No geoheritage features have been recorded within the study area or

within 1 km of the site. One Tasmania Management Act Weed has been found within 500 metres of the

study area, however this species was not recorded in the study area.
