Re: Public Consultation for DA-202341900 at Block 11, Section 1, Denman Prospect

Friends of Grasslands (FOG) is a community group dedicated to the conservation of natural temperate grassy ecosystems in south-eastern Australia. FOG advocates, educates and advises on matters to do with the conservation of native grassy ecosystems, and carries out surveys and other on-ground work. FOG is based in Canberra and its members include professional scientists, landowners, land managers and interested members of the public.

FOG is concerned that the development of Block 11 will detrimentally impact the critically endangered ecological community (CEEC) Box-Gum Woodland and its Derived Native Grassland in Block 12. The following recommendations are provided to mitigate against potential impacts on the woodland and associated species. These should be viewed in conjunction with recommendations provided in the previous submission jointly tendered by the Conservation Council and Friends of Grasslands.

1.  The open areas of Block 12 adjacent to the Denman Prospect development site are occupied by the critically endangered ecological community (CEEC) Box-Gum Woodland and its Derived Native Grassland, a fact that had not been identified in previous studies.  Data collected by Friends of Grasslands' ecologist, Rainer Rehwinkel, in 2022, has confirmed this.  The Gang-gang Cockatoo has only recently been listed as endangered so was therefore not considered in previous studies for the area.

2.  Mature native trees occur within the development envelope. These trees provide potential nesting sites for the vulnerable Superb Parrot (Polyteles swainsonii).

3.  Fire risk to residents is of significant concern. However, it is not acceptable to have the Inner Asset Zone inside the woodland in Bluetts Block. This will inevitably lead to modifications of vegetation structure, composition and condition in the endangered woodland to reduce the fire risk to residents.

4.  Domestic and feral animal impacts are likely to increase with the adjacent development.  

5.  Invasion of weeds is likely.

6.  Higher impact recreation will be detrimental to the ecological values of Bluetts Block.

7.  Education is an important component of ensuring understanding and compliance of restrictions by residents. The establishment of the Bush on the Boundary Group, a government and community stakeholder group during the development of areas within Coombs and Wright facilitated decisions about limiting risks to adjacent areas of conservation significance.

Yours sincerely
