The Arizona Mountains forests are a temperate coniferous forests ecoregion of the southwest United States with a rich variety of woodland habitats and wildlife.
This is a landscape of steep mountains and high stony plateaus with rocky outcrops from the Kaibab Plateau in northern Arizona south to the Mogollon Plateau and eastwards across into southwestern New Mexico. Elevations range from 1,370 to 3,000 meters (4,490 to 9,840 ft), with some peaks higher than that. Specific areas include the Gila Wilderness in New Mexico.
Trees of the area include some of the spruce, fir and quaking aspen ( Populus tremuloides ) trees typical of the Rocky Mountains further north along with typically Mexican trees such as Chihuahua pine (Pinus leiophylla), Apache pine ( Pinus engelmannii ) and the Arizona pine of the Gila Wilderness and elsewhere. The lower elevations have a mixed pinyon pine-juniper-oak woodland. Finally the rivers and their banks are important habitats for specific wildlife and fish.
Wildlife found here include the miniature northern saw-whet owl and many birds and reptiles that are common in Mexico further south, such as the secretive Montezuma quail. The caves of the Guadalupe Mountains are a specific habitat for beetles, centipedes and other invertebrates.
This is a fairly stable ecoregion with about 25% of original habitat still intact although vulnerable to logging and overgrazing. Pollution and reduction of rivers are threatening specific plants and animals including Fremont cottonwood ( Populus fremontii ) and Goodding's willow ( Salix gooddingii ), the threatened Gila trout ( Oncorhynchus gilae ), and the endangered southwestern willow flycatcher (Empidonax traillii extimus). Logging continues to remove habitat of the Mexican spotted owl (Strix occidentalis lucida) and the northern goshawk (Accipiter gentalis).
Large blocks of remaining habitat include: the Aldo Leopold Wilderness/Gila Wilderness/Blue Range Wilderness and the El Malpais National Monument and Conservation Area in southwestern New Mexico; the Kaibab National Forest, Blue Range Primitive Area, Grand Canyon National Park, the Mazatzal Mountains including Four Peaks, Superstition Mountains, Sycamore Canyon, Red Rock-Secret Mountain Wilderness, Hellsgate Wilderness, Pinal Mountains in the Tonto National Forest and the Galiuro Mountains in Arizona; the Chuska Mountains on Navajo lands; and the Guadalupe Mountains including the Carlsbad Caverns in southeastern New Mexico and western Texas. Much of this is linked and well-protected within national parkland.
Pinus edulis, the Colorado pinyon, two-needle piñon, pinyon pine, or simply piñon, is a pine in the pinyon pine group whose ancestor was a member of the Madro-Tertiary Geoflora and is native to the United States.

The Appalachian mixed mesophytic forests is an ecoregion of the temperate broadleaf and mixed forests biome, as defined by the World Wildlife Fund. It consists of mesophytic plants west of the Appalachian Mountains in the Southeastern United States.
The Appalachian–Blue Ridge forests are an ecoregion in the Temperate broadleaf and mixed forests Biome, in the Eastern United States. The ecoregion is located in the central and southern Appalachian Mountains, including the Ridge-and-Valley Appalachians and the Blue Ridge Mountains. It covers an area of about 61,500 square miles (159,000 km2) in: northeast Alabama and Georgia, northwest South Carolina, eastern Tennessee, western North Carolina, Virginia, Maryland, and central West Virginia and Pennsylvania; and small extensions into Kentucky, New Jersey, and New York.
Gila Wilderness was designated the world's first wilderness area on June 3, 1924. Along with Aldo Leopold Wilderness and Blue Range Wilderness, the 558,014 acres (225,820 ha) wilderness is part of New Mexico's Gila National Forest. The wilderness is approximately 27 miles (43 km) from north to south and 39 miles (63 km) east to west. U.S. Wilderness Areas do not allow motorized or mechanized vehicles, including bicycles. Camping and fishing are allowed with proper permit, but no roads, buildings, logging, or mining are permitted. Wilderness areas within National Forests and Bureau of Land Management areas allow hunting in season.
The New England-Acadian forests are a temperate broadleaf and mixed forest ecoregion that includes a variety of habitats on the hills, mountains and plateaus of New England in the Northeastern United States and Quebec and the Maritime Provinces of Eastern Canada.

The California interior chaparral and woodlands ecoregion covers 24,900 square miles (64,000 km2) in an elliptical ring around the California Central Valley. It occurs on hills and mountains ranging from 300 feet (91 m) to 3,000 feet (910 m). It is part of the Mediterranean forests, woodlands, and scrub biome, with cool, wet winters and hot, dry summers. Many plant and animal species in this ecoregion are adapted to periodic fire.
