Sampling for association analysis

Abstract

An association analysis was made of dunal heath vegetation at Gosse Hill in the Ninety-Mile Plain, South Australia, and the results compared with those of a similar analysis performed by Rayson in 1957 at Dark Island, 9 miles to the south-east in the same expanse of heath. Similarities and differences between vegetation at the two localities are described and discussed in terms of homogeneous group structure and the nature of underlying interspecific associations. It is deduced that the structure of this heath cannot be fully understood from a single analysis, and problems therefore arise in sampling for association analysis.
