A study of vegetation on the aeolian deposits of the Swan Coastal Plain, using classification techniques, revealed 49 vegetation units. These units were agglomerated into plant communities and complexes, on the basis of floristic composition. A Conspectus to the vegetation classification is provided.

Vegetation in this region is generally considered to be species-rich. Vegetation on the oldest (Bassendean) dune system was most species-rich. The complexity of vegetation pattern (vegetation texture) was greatest on the intermediate aged (Spearwood) dune system. Vegetation on the Quindalup dune system was both species-poor and had the simplest texture relative to the other two dune systems.

It is postulated that species-richness and vegetation texture change dynamically through time, as the dune systems become more stabilised and leached.

A key to the described communities is provided to allow researchers, conservation managers, teachers and other interested persons to allocate vegetation of particular bushland sites to a plant community described in the Conspectus, and thus increase knowledge of the vegetation variation in bushland remnants across this region.
