Narrow-range endemicity and conservation status: interpretations for Australian butterflies

Abstract

Small distributional range and endemism have sometimes led to concern for conservation of species, even without any evidence of threat to them. Examples from Australian butterflies demonstrate the variety of interpretations of a small distributional range, viewed commonly as 'narrow-range endemicity'. Such a pattern may be entirely natural and stable, or may represent the outcome of historical fragmentation of range, or loss of habitat resulting from past or continuing threats. Planning for any conservation management necessitates careful interpretation of the pattern shown by any given species.
