The Lower Madrean Woodlands occur at intermediate elevations, generally above 4500 or 5000 feet. The thermic soils are derived from mostly Tertiary volcanics and some Mesozoic and Paleozoic sedimentary rocks. It is a mild winter/wet summer woodland that can be shrubby in places. The Madrean encinal, or evergreen oak woodlands, have a mosaic of savannas, denser woodlands, and grassy openings. Emory, silverleaf, and Arizona white oaks occur, along with some scattered pinyon, juniper, mesquite, and chaparral species. Understory grasses can include blue grama, sideoats grama, hairy grama, little bluestem, and plains lovegrass. Pinyon-juniper woodland, with a few scattered oaks, occupies some parts of the region. Riparian areas of cottonwood, sycamore, and willow are valuable to the neotropical birds and other wildlife of the area.
