The Salt Lake Slater (Haloniscus searlei) is a unique wholly aquatic crustacean occurring in just two natural saline lagoons in the Tasmanian Midlands (it also occurs on the southern Australian mainland). While the species has been well-studied elsewhere in Australia and aspects of its biology and ecology are well-understood, in Tasmania very little is known of the factors affecting its distribution and abundance. The principal threats to the species include loss and degradation of habitat from conversion of lagoons to grazing and cropping land, modification of lagoons (e.g. draining, deepening, salt extraction), activities within the catchment of lagoons (e.g. grazing, fertilising, recreational vehicle use) and natural and anthropogenic climatic variations (leading to drying out of lagoons). The main objective for the management of the Salt Lake Slater is to decrease the risk of extinction by maintaining and improving habitat throughout the range of the species through appropriate land management.

Permit: A permit is required under the Tasmanian Threatened Species Protection Act 1995 to 'take' (which includes kill, injure, catch, damage, destroy and collect), keep, trade in or process any specimen or products of a listed species. Additional permits may also be required under other Acts or regulations to take, disturb or interfere with any form of wildlife or its products, (e.g. dens, nests, bones). This may also depend on the tenure of the land and other agreements relating to its management. ​​​​​
