The effect of a burrowing crayfish, Parastacoides sp., on the vegitation of Tasmanian wet heathlands
Published Online:
Abstract
Species in the Tasmanian endemic genus Parastacoides burrow extensively in peat soils under heathlands and sedgelands in the western parts of the state. Their burrows drain and aerate the soils, ameliorating the effects of waterlogging to some extent, but the adult crayfish feed on plant roots in their burrows. The effects of these activities on vegetation have been investigated using observations and experiments. While there are distinct correlations between crayfish distributions and vegetation boundaries, the causality of the relationship has not been clearly established.
