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. [2]
Trees of higher elevations of the area include Ponderosa pine, Blue spruce, Engelmann spruce, White fir, Rocky Mountain Douglas-fir, and Quaking aspen. The lower elevations have a mixed woodland with species such as Alligator juniper, Single-leaf pinyon, Colorado pinyon, Gambel oak, Emory oak, and Arizona white oak. 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.
Kaibab National Forest borders both the north and south rims of the Grand Canyon, in north-central Arizona. Its 1.6 million acres is divided into three sections: the North Kaibab Ranger District, the Tusayan Ranger District, and the Williams Ranger District. It is managed by the United States Forest Service. Grand Canyon National Park separates the North Kaibab and the South Kaibab. The South Kaibab covers 1,422 square miles (3,680 km2) and the North Kaibab stretches over 1,010 square miles (2,600 km2). Elevations vary on the forest from 5,500 feet in the southwest corner to 10,418 feet at the summit of Kendrick Peak on the Williams Ranger District. The forest as a whole is headquartered in Williams.
The ecology of the Sierra Nevada, located in the U.S. states of California and Nevada, is diverse and complex. The combination of climate, topography, moisture, and soils influences the distribution of ecological communities across an elevation gradient from 500 to 14,500 feet. Biotic zones range from scrub and chaparral communities at lower elevations, to subalpine forests and alpine meadows at the higher elevations. Particular ecoregions that follow elevation contours are often described as a series of belts that follow the length of the Sierra Nevada. There are many hiking trails, paved and unpaved roads, and vast public lands in the Sierra Nevada for exploring the many different biomes and ecosystems.
The Coconino National Forest is a 1.856-million acre United States National Forest located in northern Arizona in the vicinity of Flagstaff, with elevations ranging from 2,600 feet to the highest point in Arizona at 12,633 feet. Originally established in 1898 as the "San Francisco Mountains National Forest Reserve", the area was designated a U.S. National Forest by Pres. Theodore Roosevelt on July 2, 1908, when the San Francisco Mountains National Forest Reserve was merged with lands from other surrounding forest reserves to create the Coconino National Forest. Today, the Coconino National Forest contains diverse landscapes, including deserts, ponderosa pine forests, flatlands, mesas, alpine tundra, and ancient volcanic peaks. The forest surrounds the towns of Sedona and Flagstaff and borders four other national forests; the Kaibab National Forest to the west and northwest, the Prescott National Forest to the southwest, the Tonto National Forest to the south, and the Apache-Sitgreaves National Forest to the southeast. The forest contains all or parts of nine designated wilderness areas, including the Kachina Peaks Wilderness, which includes the summit of the San Francisco Peaks. The headquarters are in Flagstaff. The Coconino National Forest consists of three districts: Flagstaff Ranger District, Mogollon Rim Ranger District, and Red Rock Ranger District, which have local ranger district offices in Flagstaff, Happy Jack, and Sedona.
The Sierra Madre Occidental pine–oak forests are a Temperate broadleaf and mixed forests ecoregion of the Sierra Madre Occidental range from the southwest USA region to the western part of Mexico. They are home to a large number of endemic plants and important habitat for wildlife.
The Coconino Plateau is found south of the Grand Canyon and north-northwest of Flagstaff, in northern Arizona of the Southwestern United States.
The Kaibab Plateau is a plateau almost entirely in Coconino County, Arizona in the Southwestern United States. The high plain is also known as the Buckskin Mountain, Buckskin Plateau, and Kaibab Mountain.
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 acre 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.
The New England-Acadian forests are a temperate broadleaf and mixed forest ecoregion in North America that includes a variety of habitats on the hills, mountains and plateaus of New England and New York State in the Northeastern United States, and Quebec and the Maritime Provinces of Eastern Canada.
The Sierra Madre Oriental pine–oak forests are a temperate broadleaf and mixed forest ecoregion of northeastern and Central Mexico, extending into the state of Texas in the United States.
The Eastern Cascades Slopes and Foothills ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the U.S. states of Oregon, Washington, and California. In the rain shadow of the Cascade Range, the eastern side of the mountains experiences greater temperature extremes and receives less precipitation than the west side. Open forests of ponderosa pine and some lodgepole pine distinguish this region from the Cascades ecoregion, where hemlock and fir forests are more common, and from the lower, drier ecoregions to the east, where shrubs and grasslands are predominant. The vegetation is adapted to the prevailing dry, continental climate and frequent wildfire. Volcanic cones and buttes are common in much of the region.
The Blue Mountains ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the Pacific Northwest, mainly in the state of Oregon, with small areas over the state border in Idaho and southeastern Washington. It is also contiguous with the World Wildlife Fund's Blue Mountain forests ecoregion.
The Klamath Mountains ecoregion of Oregon and California lies inland and north of the Coast Range ecoregion, extending from the Umpqua River in the north to the Sacramento Valley in the south. It encompasses the highly dissected ridges, foothills, and valleys of the Klamath and Siskiyou Mountains. It corresponds to the Level III ecoregion designated by the Environmental Protection Agency and to the Klamath-Siskiyou forests ecoregion designated by the World Wide Fund for Nature.
The Cascade Mountains leeward forests are a temperate coniferous forest ecoregion of North America, as defined by the World Wildlife Fund (WWF) categorization system.
The ecology of the Rocky Mountains is diverse due to the effects of a variety of environmental factors. The Rocky Mountains are the major mountain range in western North America, running from the far north of British Columbia in Canada to New Mexico in the southwestern United States, climbing from the Great Plains at or below 1,800 feet (550 m) to peaks of over 14,000 feet (4,300 m). Temperature and rainfall varies greatly also and thus the Rockies are home to a mixture of habitats including the alpine, subalpine and boreal habitats of the Northern Rocky Mountains in British Columbia and Alberta, the coniferous forests of Montana and Idaho, the wetlands and prairie where the Rockies meet the plains, a different mix of conifers on the Yellowstone Plateau in Wyoming, the montane forests of Utah, and in the high Rockies of Colorado and New Mexico, and finally the alpine tundra of the highest elevations.
The Great Basin montane forests is an ecoregion of the Temperate coniferous forests biome, as designated by the World Wildlife Fund (WWF).
The Arizona/New Mexico Mountains ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the U.S. states of Arizona and New Mexico.
Saddle Mountain Wilderness is a protected wilderness area managed by the Kaibab National Forest north of Grand Canyon National Park in the U.S. state of Arizona. Established in 1984 under the Arizona Wilderness Act, the area on the Kaibab Plateau includes its namesake summit, a prominent ridge shaped like a saddle that reaches an elevation of 8,424 feet. Elevations in the northern part of the wilderness on the edge of Marble Canyon start at about 6,000 feet and rise to 8,000 on the southern ridge which forms the Nankoweap Rim of the Grand Canyon.
Northern Cordillera forests is a taiga ecoregion that extends across the northern interior of British Columbia, southern Yukon, and a small area of the Northwest Territories as defined by the World Wildlife Fund (WWF) categorization system.
