NEED IN SITU PHOTOS. Plains bluegrass has been vouchered about a dozen times from the Watershed, from scattered locations representing all mountain ranges of the Valley and a range of vegetative zones. The population in the Watershed may be larger than this scanty record indicates since Poa arida looks superficially like the common and sympatric Poa pratensis. In the USA Poa arida, perennial and cool-season, is a Rocky Mountain and Great Plains grass that follows the Rio Grande drainage spottily through New Mexico to the western tip of Texas, no farther down stream.
