shrub-steppe

The San Juan/Chaco Tablelands and Mesas ecoregion of plateaus, valleys, and canyons contains a mix of desert scrub, semi-desert shrub-steppe, and semi-desert grasslands.

Ecoregions of New Mexico (EPA) 2009

Native vegetation in the region is mostly grama-tobosa shrub-steppe in the basins and oak-juniper woodlands on the ranges, except at higher elevations where ponderosa pine is predominant.

Ecoregions of the United States-Level III (EPA) 2009

Several ecotones exist, particularly along the Cascade crest where western Cascade forest types overlap with eastern Cascade forests (e.g., the Wenatchee National Forest in Washington has conifer species present on both sides of the Cascades) and along the lower timberline where forest species mix with shrub and shrub-steppe communities.

Other losses identified in this ecoregion include degradation of shrub-steppe caused by extensive livestock grazing and invasion of exotic species, degradation of riparian, wetlands, and aquatic ecosystems, and reductions in habitat quality caused by invasive species.

Eastern Cascades forests 2009

The most densely covered is semi-desert (45%), shrub-steppe (30%), and grass-steppe (20%).

Patagonian steppe 2008

The Palouse prairie is now intensive agricultural land with patches of shrub-steppe grassland.

Palouse grasslands 2007

Vegetation from valley bottoms to mountain tops includes shrub-steppe, woodlands, pinyon pine (Pinus spp), juniper (Juniperus spp.), Douglas-fir (Pseudotsuga menziesii), and subalpine communities.

Great Basin montane forests 2007

Landscapes of this ecoregion are predominantly montane grassland with shrub-steppe below 2,000 meters (m) and meadow steppe and alpine meadow above.

Emin Valley steppe 2007

Sagebrush communities are often considered steppe or shrub steppe because of the role of grasses, and in parts of the Great Basin grasses are important understory elements in distinctly shrub-steppe communities.

While a portion of the central area is needed for Department of Energy missions, much of the area contains the same shrub-steppe habitat and other objects of scientific and historic interest that I am today permanently protecting in the monument.
