East Sahara Desert
East Sahara Desert
The East Sahara Desert is a hyper-arid ecoregion in the Deserts and Xeric Shrublands biome of the Palearctic realm, covering the central Sahara across Algeria, Niger, Libya, Chad, Egypt, and Sudan. Its landscape ranges from vast sand-dune seas to stony plateaus, gravel plains, dry wadis, and salt flats, and the flora is correspondingly sparse, dominated by xerophytes and ephemeral plants known locally as Acheb, with halophytes in moister ground. Woody vegetation is largely confined to the wadis and dayas, where Acacia, Tamarix, and Calotropis procera persist. The climate is extreme, with high summer temperatures, cooler winters, and annual rainfall below 25 mm that may fail entirely for years before a single intense thunderstorm. The hooded wheatear is the ecoregion's flagship species, and several desert antelopes such as the slender-horned, dama, and red-fronted gazelles survive in small numbers, while the critically endangered addax has been extirpated here. For arid-garden inspiration, the native Acacia and Tamarix illustrate the kind of drought-hardy genera adapted to such waterless conditions.

Use this as the broad planting pattern for the region: 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. For garden decisions, pair that context with the plant list below, then narrow by your site's light, water, soil, and mature-size constraints.

Why here
deserts & xeric shrublands conditions
The region sits in the Palearctic realm and is classed as deserts & xeric shrublands. Elevation, moisture, fire, soils, coasts, and human land use can all make the real landscape more varied than a single map color suggests.
Change pressure
Nature Could Reach Half Protected
Plotwright shows this as the current RESOLVE footprint. Over decades to centuries, warming, disturbance, invasive species, land use, and restoration can move the living edge of a region even when the reference map stays fixed.

Afghan Mountains semi-desert
The Afghan Mountains semi-desert covers three disconnected interior valleys on the northern slope of Afghanistan's central mountains, the Koh-i-Baba range and the wider Hindu Kush, reaching from the Hari River valley near Chaghcharan through the Bamyan Valley to Badakhshan Province in the east. These high, dry valleys carry an open cover of thorny shrubs and small trees generally under 1.5 metres tall, with wild almond and pistachio among the characteristic woody plants. The climate is arid and strongly continental, with large seasonal temperature swings and warm summers, and the ground is roughly two-thirds herbaceous cover and one-third bare. Several threatened animals persist here, including the endangered Kashmir musk deer, which serves as the region's flagship species, and the Persian leopard, though overgrazing by livestock presses on the vegetation and the wildlife that depends on it. The ecoregion overlaps Band-e Amir National Park, Afghanistan's first national park and an IUCN-recognized protected area. For gardeners in dry continental climates, the region's native wild almond (Prunus) and pistachio (Pistacia) are familiar drought-adapted genera.

Alashan Plateau semi-desert
The Alashan Plateau semi-desert straddles the China–Mongolia border, sitting between the Tibetan Plateau to the south and the more arid regions of the Gobi Desert to the north and east, of which it intercepts a large portion. Its basin-and-range landscape carries sparse, drought-adapted vegetation, where salt-tolerant halophytes and xerophytes such as saxaul (Haloxylon ammodendron) and Reaumuria soongorica stabilize the soil, alongside wormwoods (Artemisia) and bean caper (Zygophyllum), with desert poplar (Populus euphratica) and Tamarix along watercourses like the Yellow River. The climate is cold and very arid, with frost and snow on the dunes and very low annual precipitation (around 95 mm/year). The region shelters notable wildlife including the wild Bactrian camel, snow leopard, and Saker falcon, and the black stork serves as its flagship species, though protection remains limited amid threats from illegal mining and overgrazing. For gardeners in cold dry climates, its hardy native genera such as saxaul, Reaumuria, and Artemisia point to plants tolerant of harsh, low-water conditions.

Arabian desert
The Arabian Desert is a vast, disjointed Palearctic ecoregion that occupies most of the Arabian Peninsula and reaches across Saudi Arabia, Iraq, Jordan, Kuwait, Qatar, Oman, the United Arab Emirates, Yemen, southwestern Iran, Egypt's Sinai, and Israel's Negev. Sandy and gravel plains, elevated plateaus, and seasonal valleys called wadis dominate the terrain, supporting sparse, drought-adapted vegetation in which Acacia trees, Tamarix shrubs, and saltbushes such as Cornulaca and Salsola are characteristic, with Calligonum on dune slopes and Prosopis cineraria along desert margins. The climate is hot and arid, with very low and variable rainfall and extreme summer heat. Despite limited overall biodiversity, the region shelters specially adapted wildlife including the Arabian oryx, sand gazelles, and the Asian houbara bustard, its flagship species, but it remains poorly protected and is degraded by overgrazing, poaching, and off-road vehicle damage. For gardeners, the hardy native Acacia and Prosopis trees illustrate the drought-tolerant genera suited to hot, dry conditions.

Arabian sand desert
The Arabian Sand Desert spans the great sand seas of the Arabian Peninsula, lying predominantly in Saudi Arabia and crossing into the United Arab Emirates, Yemen, and Oman; it takes in the Rub' al-Khali, or Empty Quarter, the world's largest sand desert, along with the an-Nafud, ad-Dahna, and al-Jafurah dune fields of linear and crescent dunes interspersed with gravel and gypsum plains. Vegetation is sparse and highly drought-adapted, with Calligonum shrubs colonizing dune slopes alongside chenopod genera such as Cornulaca and Haloxylon, while scattered trees including Acacia ehrenbergiana and the ghaf (Prosopis cineraria) persist mainly along the desert margins. The climate is hyper-arid and intensely hot, with summer temperatures that can exceed 50 degrees Celsius and scant, seasonal rainfall that falls off from north to south. Despite its name, the Empty Quarter is far from lifeless: it is the stronghold for the reintroduced Arabian oryx, the ecoregion's flagship species, which was restored after near-extinction from overhunting in the mid-twentieth century. Gardeners drawn to xeric planting will recognize ghaf (Prosopis cineraria) and Acacia among the heat- and drought-hardy genera native here.

Arabian-Persian Gulf coastal plain desert
The Arabian-Persian Gulf Coastal Plain Desert traces the eastern seaboard of the Arabian Peninsula along the Arabian-Persian Gulf and Gulf of Oman, taking in coastal stretches of Kuwait, eastern Saudi Arabia, the United Arab Emirates, and Oman while encompassing the entire land area of Qatar and Bahrain. It is a mosaic of low coastal habitats: rocky shores, intertidal mudflats, salt marshes known as sabkha, gravel hammada, sand dunes, and pockets of Avicennia mangrove, where vegetation is dominated by salt-tolerant halophytes and sparse desert shrubs and grasses such as Haloxylon salicornicum, Rhanterium, and the sedge Cyperus conglomeratus. The climate is hot and intensely arid, with annual rainfall below roughly 100 millimeters across most of the region. These shores form a haven for wildlife, hosting the world's largest breeding population of the Socotra cormorant alongside sand gazelle, wintering shorebirds, and sandy beaches that serve as nesting sites for several threatened sea turtle species. Only about four percent of the ecoregion is protected, and coastal development, overgrazing, and overfishing remain the principal threats.

Azerbaijan shrub desert and steppe
The Azerbaijan shrub desert and steppe is a Deserts and Xeric Shrublands ecoregion occupying the Kura-Aras lowlands west of the Caspian Sea, with about seventy percent in Azerbaijan and the rest reaching into southeastern Georgia and northwestern Iran. It is the driest part of the Caucasus, a mosaic of wormwood (Artemisia) and saltwort (Salsola) semi-desert, feather-grass (Stipa) and yellow-bluestem steppe, and open pistachio-juniper woodlands, with riparian forests and wetlands along river floodplains. The climate is semi-arid to arid, temperate and continental, with long hot summers, short mild winters, and average annual precipitation of roughly 300 to 400 millimeters. Despite high endemism and a role as home to the world's largest population of goitered gazelle, only about six percent of the ecoregion lies within protected areas such as Shirvan and Aghgol national parks. For gardeners in dry, continental climates, the region's native flora includes drought-adapted ornamentals like feather grasses (Stipa) and endemic irises.
