Abstract
Radiation-vegetation relationships for 12 species of Eucalyptus from the so uth coast of New South Wales showed that the mean radiation values differed significantly between species. Confidence intervals around the mean radiat ion values, based on pooled standard deviation, were used as an index of sp ecies generality. There were differences in the size of the confidence inte rvals between species. While E. bosistoana and E. maidenii had large confid ence intervals over all seasons, E. sieberi, E. muellerana, and E. globoide a had very small confidence intervals. The species also exhibit a shift in the relative positions of their confidence intervals according to season. C learly, radiation data are an important variable for eucalypt species delin eation, and may be included as an explanatory variable when modeling the di stribution of eucalypts. Solar radiation was calculated for the different seasons of the year using a model developed within a geographic information system (GIS); the input t o the model is simply a digital elevation model (DEM) and the latitude of t he site.
