EPA Level I Region
Temperate Sierras
Temperate Sierras covers the Arizona and New Mexico mountains, the pine and oak highlands that rise out of the desert around Flagstaff, Payson, and the Mogollon Rim. Elevation brings real winters and cooler summers than the surrounding lowlands, along with a reliable summer monsoon. Natives like Rocky Mountain penstemon, apache plume, and Gambel oak suit that mix of cold nights and late-summer rain.
Ecoregions inside it: 1. Native range is set at that finer level, so start there rather than here.
