NEED IN SITU PHOTOS. In the Watershed, Scribner's needlegrass has been vouchered more than twenty times, usually from pinyon-juniper sagebrush foothill habitat. There is a concentration of occurrences northwest of the town of Saguache in the South Sawatch range. The two Lower Basin records were identified by H. Dixon from the San Luis Hills (1966, Conejos Co). Eriocoma scribneri (usually under the name Achnatherum scribneri) has a fairly restricted USA range: the southern Rockies of Colorado and New Mexico, with a few locations in northeast Arizona and southern Utah. According to BONAP (2025), the species follows the Rio Grande drainage through New Mexico to the western tip of Texas, but no farther down stream.
