Engaeus yabbimunna

Abstract: Engaeus yabbimunna, a small burrowing crayfish, appears to be restricted to an area ofless than 9 km 2 within the catchments of Shorewell, Romaine and Cooee creeks in the township of Bumie in north-west Tasmania. It has been confirmed at ten sites with four of these containing only small populations and the two largest populations occurring in Bumie City Council reserves. The species is largely restricted to isolated pockets of remnant native vegetation along creeks and seepages within the Bumie urban environment. Removal of remnant riparian vegetation within the species' range is continuing. The E. yabbimunna population is further threatened by pollution from council refuse sites as well as poaching and removal of individuals by children. Due to its exceptionally restricted distribution, its likely past decline and continuing threatening processes acting on the species, E. yabbimunna warrants classification as endangered. Management requirements for the species, including the need for community participation, are discussed.
