NEED IN SITU PHOTOS. Alpine bentgrass has been vouchered only a few times within the Watershed, although there are many records from just west over the Continental Divide. Three locations are Wolf Creek pass (Rio Grande Co, 1936), Grayback Mountain, south of Del Norte (Rio Grande Co, 1978), and Elwood pass (Rio Grande Co, 2002). Podagrostis humilis is usually found in alpine meadows or among trees (aspen, spruce) in the subalpine. In the USA, its typical range is the Sierra Nevadas and the Rocky Mountains, with fewer locations in the Intermountain region. In Colorado it has been recorded most often in the central Rockies, from the Wyoming border to the New Mexican. But it is not yet found in New Mexico or farther down the Rio Grande drainage. The Watershed occurrences then are the only ones in this drainage.
