Palouse prairie
Palouse prairie
The Palouse Prairie is a temperate bunchgrass grassland of the Columbia Basin spanning eastern Washington, western Idaho, north-central Oregon, and south-central British Columbia. Its rolling hills were originally dominated by perennial cool-season grasses such as bluebunch wheatgrass, Idaho fescue, Sandberg bluegrass, and giant wildrye. The climate brings warm, dry summers and cold winters, with low precipitation (about 571 mm a year) falling mostly in winter. Notably, roughly 99.9% of the prairie has been converted to agriculture, chiefly wheat, making it one of the most endangered ecosystems in the United States.

Use isto como o padrão geral de plantio para a região: Temperate prairies, steppes, and pampas of grasses and forbs with few trees, under continental climates of hot summers and cold winters. Their deep, fertile soils have made them among the most extensively converted biomes for agriculture. Para decisões de jardim, combine esse contexto com a lista de plantas abaixo e depois refine pelas restrições de luz, água, solo e tamanho adulto do seu local.

Por que aqui
Condições de temperate grasslands, savannas & shrublands
A região fica no reino Nearctic e é classificada como temperate grasslands, savannas & shrublands. Altitude, umidade, fogo, solos, costas e o uso humano da terra podem tornar a paisagem real mais variada do que uma única cor no mapa sugere.
Pressão de mudança
Nature Could Recover
O Plotwright mostra isto como a pegada RESOLVE atual. Ao longo de décadas a séculos, o aquecimento, as perturbações, as espécies invasoras, o uso da terra e a restauração podem mover a borda viva de uma região mesmo quando o mapa de referência permanece fixo.
Coleções de plantio

California Central Valley grasslands
The California Central Valley grasslands fill the long lowland between the Sierra Nevada to the east and the Coast Ranges to the west, spanning the Sacramento Valley in the north and the San Joaquin Valley in the south. The climate is Mediterranean, with most rain falling in winter and conditions growing drier from north to south and on the western, rain-shadowed side. Historically a mosaic of perennial bunchgrass prairie, oak savanna, vernal pools, and riparian woodland, the region is now largely converted to farmland and dominated by introduced annual grasses. It is one of North America's most altered grasslands: less than 1% of native grassland remains and only about 4% is protected.

Canadian Aspen forests and parklands
The Canadian Aspen forests and parklands — the transitional belt between the northern prairies to the south and the boreal forest to the north, covering southern Saskatchewan, southern + central Alberta, southwestern Manitoba, and small extensions into Montana and the Dakotas. Quaking aspen groves interspersed with grassland; the ecoregion functioned historically as a fire-managed mosaic, and woody encroachment under fire suppression has shifted the balance toward more closed aspen forest.

Central Tallgrass prairie
The Central Tallgrass Prairie — the historical core of the North American grassland biome, covering Iowa, northern Missouri, Illinois west of the Indiana hardwood line, eastern Kansas, eastern Nebraska, and the southern parts of Wisconsin and Minnesota. Big bluestem, Indiangrass, switchgrass, and side-oats grama on the dominant matrix; the deep-rooted forb diversity (Echinacea, Liatris, Silphium, Baptisia, Asclepias) underpins much of the modern native-plant-garden palette. Less than 4% of the original tallgrass remains; conservation collections matter disproportionately.

Central US forest-grasslands transition
The Central US forest-grasslands transition is an ecotone stretching across the central Midwest—including Illinois, Indiana, Wisconsin, Missouri, Iowa, and Kentucky—where the eastern deciduous forests of the United States give way to the tallgrass prairies of the eastern Great Plains. Its presettlement landscape was a mosaic of oak savanna, bluestem prairie, and oak-hickory and maple-basswood forest, with glacial moraines, dunes, fens, and marshes common in the Chicago Lake Plain along Lake Michigan. The climate ranges from humid warm continental to humid cold temperate. Now encompassing major metropolitan areas including Chicago and Milwaukee and reaching south toward St. Louis, the region has lost over 95% of its presettlement vegetation, with only about 3% protected.

Central-Southern US mixed grasslands
The Central-Southern US Mixed Grasslands run north to south from central Nebraska through Kansas and Oklahoma into north-central Texas, a vast prairie marking the ecological transition from tallgrass to shortgrass plains. Its flat-to-rolling, wind-deposited terrain (about 400-1,220 m elevation) carries native mixed-grass prairie of tallgrasses such as big bluestem and Indiangrass alongside shorter grasses, and OneEarth notes it holds the greatest floristic complexity of all North American grasslands. The climate is subhumid warm continental to warm temperate, with annual precipitation ranging from roughly 300 to 812 mm. Each spring more than 500,000 sandhill cranes (about 80% of the world's population) gather along Nebraska's Platte River, though only about 1% of the ecoregion is protected.
