The Madrean Lower Montane Woodlands ecoregion covers slopes of the Guadalupe, Sacramento, Mimbres, Big Burro, and Mogollon mountains in New Mexico, and extends across the middle elevations of the Mogollon Transition in Arizona. Elevations are mostly 4200 to 7000 feet, with juniper, pinyon, and oak densities varying according to aspect. Compared to the woodlands of Ecoregion 23e, this region has milder winters, wetter summers, and some different plant species. At middle elevations, a chaparral community occurs beneath the trees, composed of shrubs such as desert ceanothus, alderleaf mountain-mahogany, turbinella oak, manzanitas, and catclaw mimosa. Other areas are grassy and park-like with mixed gramas and scattered trees. Pinyon, alligator and one-seed juniper, and Madrean oaks such as Gray and Emory oak occur. A few areas of ponderosa pine and Madrean oaks are found at the highest elevations.
