Brief description

Sandy beaches on Tasmania's east coast, from Catamaran to Cape Portland, were sampled between September 1994 and June 1995. At each of 120 sites the strandline fauna was sampled using pitfall traps set overnight during the low tide period. A number of physical and biotic characteristics of each beach were also measured.

Statement: The macro-invertebrate fauna of the upper zone of beaches is almost entirely made up of species that are active on the sand surface, usually at night. Since the habitat is spatially homogenous, pitfall trapping was used. Simple traps were used, consisting of a 7.5cm diameter plastic drinking cup dug into the sand, containing about 25ml of ethylene glycol, a non-volatile preservative. The traps were set in three groups of five. Each beach was divided into three zones: the middle zone (Zone 2) was defined as the strandline, Zone 1 was located immediately seaward of the strandline, while Zone 3 was defined as the belt between the upper limit of the strandline, and the seaward edge of terrestrial, woody vegetation.
