Vegetation Type 2 (VT2) with the proposed action area was described as Eucalyptus rudis and Corymbia calophylla woodland over Acacia saligna tall sparse shrubland over mixed exotic herbs and grasses. Foraging habitat for black cockatoos within the development area is limited to scattered Marri, Jarrah and Pine trees which provide a moderate quality food resource for all three species of black cockatoos. Aerial mapping of the canopy cover of these trees was undertaken and it was determined that 3.71 ha of moderate quality habitat for CBC, BBC and FRTBC occurs within
Referral trigger Assessment of proposed action against referral trigger
Clearing of any known nesting tree The proposed action will not result in the clearing of any known nesting trees.
No evidence that trees have been used or were currently being used by black cockatoos for nesting purposes was recorded within the proposed action area.
Clearing or degradation of any part of a vegetation community known to contain breeding habitat
No active nests were recorded within the proposed action area.
60 significant trees (with potential to provide future breeding habitat), including four trees which contain hollow suitable for use by black cockatoos, may be affected by the proposed development.
Clearing or degradation of more than 1 ha of quality foraging habitat
Up to 3.71 ha of moderate quality black cockatoo foraging habitat may be cleared as a result of the proposal.
Clearing or degradation of a known night roosting tree
The proposed action will not result in the clearing of any known roosting trees.
No known night roosting trees have been recorded within the proposed action area.
Creating a gap of more than 4 km between patches of black cockatoo habitat
The proposed action area is located in close proximity to a number of existing reserves containing potential black cockatoo habitat (Figure 4) including:
• Mundy Regional Park 1.15km
• Dawson Reserve 1.3km (Bush Forever Site 319)
• Pioneer Park 2.2km (Bush Forever Site 440)
• Bush Forever Site 401 <1 km.
As such, the proposal will not create a gap of more than 4 km between patches of habitat.
Will the action lead to a long-term decrease in the size of a population?
The proposed action area contains approximately 3.71 ha of foraging habitat for Carnaby’s Black Cockatoo (Figure 3).
While the local extent of foraging habitat will be reduced as a result of the proposed action, the proposed clearing will not lead to a long term decrease in the size of the Carnaby’s Black Cockatoo population due to:
• no evidence of breeding or roosting has been recorded within the proposed action area
• limited clearing of degraded quality foraging habitat
• suitable alternative habitat s available in the Mundy Regional Park (<1.5 km to the east), in Dawson Reserve (<1.5 km to the west) and Pioneer Park (<2.5 km to the southwest) (Figure 4)
• the nature of Carnaby’s Black Cockatoo populations, which are highly mobile with extensive ranges.
On this basis, clearing is not expected to impact the sustainability of any Carnaby’s Black Cockatoo population.
Will the action reduce the area of occupancy of the species?
The proposed action will not significantly reduce the area of occupancy of Carnaby’s Black Cockatoo. Suitable habitat is available in the Mundy Regional Park (<1.5 km to the west), in Dawson Reserve (<1.5 km to the west) and Pioneer Park (<2.5 km to the southwest). Protected reserves exist within a 3 km radius of the proposed action area and therefore is unlikely to significantly reduce the area of occupancy of Carnaby’s Black Cockatoo (Figure 4).
Will the action fragment an existing population into two or more populations?
The proposed action area is bounded to the east by semi cleared rural properties residential development to the north and west and schools to the south. Carnaby’s Black Cockatoos are highly mobile and the clearing of 3.71 ha of Carnaby’s Black Cockatoo habitat required will not present a barrier to movement across the region.
Will the action adversely affect habitat critical to the survival of a species?
The proposed action area contains 3.71 ha of excellent quality foraging habitat for Carnaby’s Black Cockatoos. However, there are no known breeding or roosting sites within the proposed action area and the area is located outside of the breeding range for Carnaby’s Black Cockatoo.
Suitable Carnaby’s Black Cockatoo foraging habitat occurs in long-term conservation areas located in the Mundy Regional Park (<1.5 km to the east), in Dawson Reserve (<1.5 km to the west), Lesmurdie Falls National Park (<2.5 km to the southeast) and Pioneer Park (<2.5 km to the southwest) (Figure 4). The proposed clearing represents a small portion of the overall habitat available to the species reserved in the conservation areas listed above, within a 3 km radius of the proposed action area; therefore not considered critical to the survival of the species.
Will the action disrupt the breeding cycle of a population?
There are no known breeding or roosting sites within the proposed action area and the area is located outside of the breeding range for Carnaby’s Black Cockatoo. The clearing of this area is therefore unlikely to contribute to an increase in competition for nest hollows. On this basis the action will not disrupt the breeding cycle of a population.
The proposed action is also unlikely to disrupt the breeding cycle of Carnaby’s Black Cockatoo populations due to the small size of the proposed clearing and the proximity of the proposed action area to reserved areas containing high quality alternate foraging vegetation, within a 3 km radius (Figure 4).
Will the action modify, destroy, remove, isolate or decrease the availability or quality of habitat to the extent that the species is likely to decline?
The proposed action is unlikely to modify, destroy, remove, isolate or decrease the availability or quality of habitat to the extent that the species is likely to decline. The action will remove approximately 3.71 ha of Carnaby’s Black Cockatoo foraging habitat.
Habitat for these species is available in nearby vegetation in the Mundy Regional Park (<1.5 km to the east), in Dawson Reserve (<1.5 km to the west) and Pioneer Park (<2.5 km to the southwest) (Figure 4).
Therefore the proposed action is unlikely to cause these species to decline.
Will the action result in invasive species that are harmful to critically endangered or endangered species becoming established in the endangered or critically endangered species’ habitat?
Habitat contained in the proposed action area is already completely degraded. Also, given that the majority of this habitat is adjacent to existing residential garden areas; it is unlikely the development will result in any new invasive species becoming established. Weed species that may occur predominately affect the vegetation understorey and are unlikely to significantly affect the foraging and breeding habitat quality of the vegetation.
Will the action introduce disease that may cause the species to decline?
A dieback survey of the proposed action area has not been undertaken; however, the proposed action area has been subject to a range of previous disturbances such as clearing and agriculture. Disturbance for the proposed action is therefore unlikely to introduce new plant diseases to the proposed action area.
