Rainfall data from Riverside weather station. then distance between reserves within the current range cannot guard against the impacts of drought. A better way to buffer the species against a series of very dry years may be to rely on the fortuitous survival of D. stephensi in refiiges with higher than average rainfall. The locations of such potential refuges should be an object of future study. In addition, corridors of appropriate habitat between re- serves could allow for recolonization from populated areas to extirpated patches. Regional Rainfall Amounts Although rainfall is highly correlated among rain stations, results of the one- way ANOVA of differences in log annual rainfall among rain stations show a.
