Abstract

Two classifications are currently used to describe crayfish burrowing. One classification describes groups of North American crayfish, based in part, on the burrow’s relation to the water table, surface water, burrow complexity and time spent in the burrow. The other describes the burrows of Australian crayfish in relation to surface water and the water table. Proposed is a classification that describes ecological groups of crayfish at two scales by using terms from the established schemes in a hierarchical structure. The proposed classification identifies groups of crayfish based on their distribution at the landscape in relation to surface water, and within landscape patches in relation to the water table and with respect to life history strategies independent of the water table.
