Fauna

Ongoing quarry activities will provide an opportunity to restore wildlife habitats and corridors through cleared land and link vegetation of regional significance.

In the southern sector of the site there is an opportunity to restore a wildlife corridor up to 200 to 300 metres in width.

A fauna survey was carried out in April 2004 and updated in April 2006.  130 species were found at the site, including 22 species of mammal, 88 species of bird, 14 reptiles, and 6 amphibians. Most of these are classified as Common Wildlife, which is to say they are not classified as Presumed Extinct, Endangered, Vulnerable, or Rare.  Some of these were introduced species (e.g. cows).

The species that were identified as being of special interest are as follows:

Koala

Koala (Phascolarctos cinereus)

Vulnerable with Special Cultural Significance

Koalas are the most important species at this site, and it is primarily because of their presence that this particular quarry requires careful and special focus for environmental management. (See Koalas).   Preservation and restoration of koala habitat (i.e. replanting and regeneration of native trees on the cleared lands of the site) will benefit all native fauna at the site.

Grey-headed Flying Fox

Grey-headed Flying Fox (Pteropus poliocephalus)

Vulnerable

The Grey-headed Flying Fox has not actually been observed at the site, and no colonies or camps have been found, however it is expected to visit the area seasonally, and especially in response to flowering. It has been concluded that the quarry extension would not impact the species, and in fact the restoration of habitat will provide extra food sources.

Powerful Owl

Powerful Owl (Ninox strenua)

Vulnerable

This species has not been seen at the site, however they have been observed in the adjacent national park and surrounding areas and it is considered likely that they visit the site for food. These birds use hollows in old growth eucalypts for nesting. The site does contain some of these trees, however they are outside the area of the quarry extension and will be retained. Also, the establishment of eucalypt woodland habitat in the southern part of the site will ultimately improve habitat conditions for this species.

Tusked Frog

Tusked Frog (Adelotus brevis)

Vulnerable

The Tusked Frog is usually associated with permanent waterways, and the site does contain portions of waterways and vegetation that could provide ideal habitats for this species. These are in the north and east areas of the site, outside of the extraction area.  The wet areas within the extraction area do not contain habitat for these frogs, and the fauna study concluded that they will not be adversely affected by the extension.

Short-beaked Echidna

Short-beaked Echidna (Tachyglossus aculeatus)

Common Wildlife with Special Cultural Significance

The Short-beaked Echidna will not be adversely affected by the quarry extension; in fact, rehabilitation of the southern part of the site will provide them with more habitat.

Black-faced Monarch

Migratory Birds

Common Wildlife

The migratory birds observed at the site include the Cattle Egret, Rainbow Bee-Eater, Black-faced Monarch, Rufous Fantail, White-throated Needletail, and Spectacled Monarch. Although classified as Common Wildlife, they are all listed in international migratory treaties and therefore require consideration.  There is abundant habitat for these species outside the area of the proposed quarry extension, and it was the conclusion of the fauna assessment that they will not be adversely affected by the presence of the quarry.

Findings of the fauna study will provide a basis for preparing soundly based Fauna Management and Buffer Land Management Plans for protection, restoration and management of wildlife habitat.
