Abstract

The vegetation of the Lower Gordon Ri vel' Basin consists of rainforest, sclerophyll forest, scrub and sedgeland-heath, each of which is composed of a number of plant communities forming an intricate mosaic.
Field studies conducted over three summer seasons suggest that differential fire regimes are the primary determinants of the composition, structure and distribution of the major vegetation types. Climatic, topographic and edaphic factors play a relatively minor role except through their interaction with the fire regime.
The observed patterns and processes in the major vegetation types can be interpreted readily in terms of vegetation succession and ecological drift, but the ubiquity of diffuse ecotones argues against the occurrence of stable fire cycles.
