Snake-Columbia shrub steppe

Snake-Columbia shrub steppe

Snake-Columbia shrub steppe
The Snake-Columbia shrub steppe is a vast arid ecoregion stretching across the Columbia Basin of Washington, southeastern Oregon, northern Nevada, extreme northeastern California, southern Idaho, and a small part of western Wyoming. Its landscape of basins, playas, and wetlands punctuated by steep fault-block mountains is dominated by big sagebrush and perennial grasses such as bluebunch wheatgrass and Idaho fescue, with western juniper woodlands and a biological soil crust of lichens, fungi, and cyanobacteria. Summers are warm to hot and winters cold, with limited precipitation that varies sharply by rain shadow. The greater sage-grouse is the flagship species; major threats include livestock grazing, juniper expansion from fire exclusion, and cheatgrass invasion that has made wildfires unnaturally frequent.

Utilisez ceci comme schéma général de plantation pour la région : Arid and semi-arid lands where low, erratic rainfall and high evaporation limit vegetation to drought-adapted shrubs, succulents, and sparse grasses. Day-to-night temperature swings are large, and life is finely tuned to water scarcity.

Conditions de deserts & xeric shrublands
La région se situe dans le règne Nearctic et est classée comme deserts & xeric shrublands. L'altitude, l'humidité, le feu, les sols, les côtes et l'utilisation humaine des terres peuvent tous rendre le paysage réel plus varié qu'une seule couleur de carte ne le laisse penser.

Plotwright affiche ceci comme l'empreinte RESOLVE actuelle. Au fil des décennies ou des siècles, le réchauffement, les perturbations, les espèces envahissantes, l'utilisation des terres et la restauration peuvent déplacer la bordure vivante d'une région même lorsque la carte de référence reste fixe.

Baja California desert
The Baja California desert spans the western Baja California Peninsula in Mexico, across both Baja California and Baja California Sur states, bounded by the Pacific to the west and the Peninsular Ranges to the east. Its xeric shrublands hold close to 500 vascular plant species, including the endemic boojum tree (Fouquieria columnaris), creosote bush, and many cacti, with roughly 23% of plant species endemic. The climate is dry and mostly subtropical; the Pacific Ocean adds humidity and moderates temperatures, while the driest interior areas receive less than 50 mm of rain a year. About 60% of the ecoregion lies in protected areas, including Mexico's El Vizcaíno Biosphere Reserve.

Central Mexican matorral
The Central Mexican matorral is a semi-arid shrubland ecoregion of roughly 59,400 sq km on the southern Mexican Plateau, encompassing the Valley of Mexico and Mexico City, North America's largest metropolis. This relatively flat desert reaches elevations up to about 2,000 m and is ringed and dotted by mountain ranges. Its climate is subtropical and semi-arid, with warm summers, occasional summer rains, and cool winters; average annual precipitation is under 500 mm. The characteristic vegetation is dry matorral dominated by cacti, agaves, and shrubs such as lechuguilla and acacias, with the golden barrel cactus (Echinocactus grusonii) as a flagship species. Geographic isolation drives exceptionally high endemism, but the ecoregion is classified critical/endangered, with little protected habitat and pressure from agriculture, grazing, urban growth, and illegal cactus collection.

Chihuahuan desert
The Chihuahuan desert — the largest North American desert, covering western Texas, southern New Mexico, southeastern Arizona, and substantial portions of the Mexican states of Chihuahua, Coahuila, Durango, and Zacatecas. Higher and cooler than the Sonoran; summer monsoonal rainfall supports the largest cacti diversity in North America (~350 species), with creosote bush, lechuguilla, sotol, and Yucca matrix species. Big Bend National Park covers a famous US portion.

Colorado Plateau shrublands
The Colorado Plateau shrublands stretch across the high desert country of Utah, Colorado, Arizona, and New Mexico, an elevated, northward-tilted saucer largely above 1,525 meters and ringed by higher mountains. Pinyon-juniper woodlands dominate, grading into big sagebrush and semi-desert shrubland at lower elevations and ponderosa pine forest higher up. The climate is arid to semiarid, with cold winters and hot summer days. Carved by the Colorado River and its tributaries, the region holds iconic landscapes such as the Grand Canyon and roughly 300 endemic plant species, yet only about 11% is protected.

Great Basin shrub steppe
The Great Basin shrub steppe spans most of Nevada and much of Utah, with adjoining areas of California and Idaho, bounded by the Sierra Nevada to the west and the Wasatch Mountains to the east. Its landscape is a series of uplifted fault-block mountains separated by intervening basins, vegetated by big sagebrush along with bluebunch wheatgrass, Idaho fescue, and pinyon-juniper woodlands. The climate is extreme and arid: less than 250 mm of annual precipitation, with recorded temperatures at Elko, Nevada ranging from -42°C to +42°C. Roughly 100 internally drained basins hold remnant Pleistocene lakes such as Great Salt Lake and Pyramid Lake. Invasive cheatgrass and the unnaturally frequent fires it fuels are a leading conservation threat.

Gulf of California xeric scrub
The Gulf of California xeric scrub runs down the eastern side of Mexico's Baja California Peninsula along the Gulf of California, from the gulf shore up to the crest of the Sierra de la Giganta and across several gulf islands, covering roughly 23,600 km2. It is a dry, low-mountain landscape (mostly 200-1,000 m) of desert shrubland dominated by creosote bush, white bursage, and ironwood. The climate is arid and subtropical, with some of the lowest precipitation in all of Mexico (under 100 mm). Distinctively, much of the region's biodiversity and high endemism is tied not to the open scrub but to scattered palm oases; roughly half the ecoregion lies within protected areas.
