Western short grasslands
ecoregion (WWF)
The Western short grasslands is a temperate grassland ecoregion of the United States.
Setting
This ecoregion largely corresponds with the geographical region known as the High Plains. It is located in southeastern Wyoming, western Nebraska (the Nebraska Panhandle), eastern Colorado, western Kansas, western Oklahoma (the Oklahoma Panhandle), eastern New Mexico, the Texas Panhandle and parts of west-central Texas and a very small portion of southwestern South Dakota. The Western short grasslands are characterized by a semi-arid climate, with low precipitation, warm temperatures, and a long growing season relative to other Nearctic prairie ecoregions.
Flora
The two dominant grasses of this ecoregion are blue grama (Bouteloua gracilis) and buffalograss (Bouteloua dactyloides).
Fauna
Mammals of this ecoregion include bison (Bison bison bison), mule deer (Odocoileus hemonius) and coyote (Canis latrans). Birds include the lesser prairie-chicken, greater prairie-chicken, dickcissel and loggerhead shrike. This ecoregion is home to a very diverse assortment of butterflies, birds, and mammals, due in part to its proximity to the subtropics.
Threats and preservation
Most of this ecoregion is occupied by farms and ranches, and cattle grazing has affected 75% of the Western short grasslands, particularly the southern portion. This overgrazing has led to an invasion of desert scrub plants from the southwest, such as mesquite.
“Western short grasslands” enters the record as ecoregion (WWF). Crown Archives preserves that source wording while asking what Western, short and grasslands can confirm, complicate or overturn.
Why this record matters
“Western short grasslands” is worth following because a concise public description often conceals a longer documentary argument. Here, Western, short and grasslands provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Oct 14, 2025. The linked authority identifier is Q7988534. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
