Plant communites of the coastal lowlands of Tweed Shire, on the far north coast of New South Wales (Australia) are described. The communities are grouped into three broad categories: Floodplain wetlands which are not further subdivided; estuarine wetlands in four communities; and floodplain forest and the vegetation of dunal areas with 16 sampled communities and brief descriptions of alluvial forest, foredune formations and additional emergent wetland communities. The occurrences of 505 plant taxa in relation to the sampled communities are listed. Natural vegetation in the study area occupied about 3,300 ha at the time of mapping in 1985. This represents a decline of over 87% from its original extent. The formal reserves in the study area fail to represent much of its natural diversity. The coverage and level of protection provided by less secure conservation measures hould be extended. Increased efforts at conservation planning are needed, particularly because of the biogeographic significance of the area, the significance of some habitats for the mobile fauna of a region much larger than the Shire, the many rare, threatened or otherwise significant species, and the inevitable limitations of available data as a basis for ensuring the adequate protection of the area's species.
