Conserving a network of representative physical environments is a strategy that could conserve species both now and into the future, while allowing them to move in response to the climate. The key to implementing such a strategy is to define the physical environments in a way that is maximally relevant to species. We created comprehensive maps of geology, elevation zones, and landforms for the Eastern U.S. and then examined the relationships between these factors and 3434 rare species at 85,613 locations. Based on an index of importance derived from the number of species samples and an index of the percent above expected that a species was found on a feature, most species showed strong preferences for specific settings:...
Enduring features (EFs; geophysical settings) are worthy conservation targets. We assembled data on EFs for the nation and performed an ecoregion-based GAP Analysis on their conservation status. Ecoregions that circumscribe mountains tend to have more EFs, and ecoregions in the west, where public lands make up more of the total land area, have more EFs within conservation lands. The middle of the country is relatively low in EF diversity, but nonetheless the number of EFs in conservation lands is low. Areas of high EF diversity in the Edwards Plateau also contained a diversity of rare species occurrences. We generated a new EF data set for the eastern USA and evaluated the distribution of rare species in terms of...
