Abstract—The Apache Highlands ecoregion incorporates the entire Madrean Archipelago/Sky
Island region. We analyzed the current distribution of 223 target species and 26 terrestrial ecological
systems there, and compared them with constraints on ecosystem integrity (e.g., road
density) to determine the most efficient set of areas needed to maintain current biodiversity. The
resulting portfolio of 90 areas includes 12.5 million acres (5 million ha) that should be priorities for
protection. Conservation strategies include protection and restoration of grasslands, restoration or
maintenance of natural fire regimes, and learning more of probable effects of climate change.[AUTHOR ABSTRACT]
