Accurate mapping of a species’ distribution is extremely important, particularly in an age where satellite imagery and habitat maps can be linked with management scenarios involving issues of population viability, land-use planning, and habitat quality, quantity, and distribution (Wisdom, Rowland, et al. 2002, Wisdom, Wales, et al. 2002). These possibilities are complicated by variation in types of distributions. For example, some maps are not available at a scale adequate for specific management concerns. Furthermore, the distribution for most species is not constant. Some species may acquire range or become extirpated in areas, with the contractions and expansions resulting in an altered current distribution.
