Abstract
The range of an endangered burrowing crayfish, Engaeus granulatus, from north central Tasmania was mapped following an extensive field survey. The survey located 35 new populations of the species, extending its known range from 343 to 515 km2, but its likely area of occupancy remains below 1 km2. Overall population estimates ranged from 392,200 to 74,400 individuals. An environmental domain modeling program, CORTEX, predicted a small amount of suitable habitat beyond the species’ known range, mostly to the north east, but other collections suggest that it is unlikely that E. granulatus has colonised these areas, probably because of habitat barriers or interactions with other Engaeus spp. Fine-scale modeling is planned to more accurately predict the species’ habitat use within its range, for use as a management tool.
