Due to the potential for impacts to the surface environment, including vegetation clearing and changes to surface hydrology and the potential for subsequent impacts to Short Range Endemic (SRE) invertebrates in the site, Emerge Associates (Emerge) on behalf of Peet Stratton has requested Invertebrate Solutions undertake a desktop review of SRE invertebrates and preliminary impact risk assessment for the proposed development. The broader Desktop Study Area contains 11 Confirmed SRE species (four land snails, four mygalomorph trapdoor spiders, three groundwater amphipods, and one tree cricket), four Likely SRE species (two tree crickets, one mygalomorph trapdoor spider, and one millipede), and two Possible SRE species (one springtail and one midge). The remainder of the species were found to be widespread. Within Lot 102 Farrall Rd, Midvale, there are no Confirmed SRE species that have a High Likelihood of occurrence. The only direct impact to SRE fauna is from vegetation clearing within Lot 102 Farrall Rd, Midvale that will directly remove habitat used by SRE species. Given the sites small size and that the majority of vegetation that is not degraded will be preserved and conserved the likely impact is considered Low and it is considered unlikely that the site would result in local extinction or significant impact to any SRE or conservation significant invertebrate species. The indirect impact of the clearing of native vegetation causing fragmentation of the remaining vegetation may lead to the restriction of genetic flow for SRE species that have limited dispersal capabilities.
