- NEED IN SITU PHOTOS. There are no SEINet records for prairie sandreed from the Watershed. However, Shaw (2008) shows Alamosa and Saguache counties, and Dixon (2012) cites it as occurring in "moist, sandy places, valley floor," and includes it in his checklist of of plants from the Great Sand Dunes NP (1999). Vouchers, then, may exist in the Adams State herbarium among the half that have not been catalogued as yet (2025). BONAP accepts the Great Sand Dune location. Calamovilfa longifolia grows in sandy loam and sand dunes. Its USA distribution is northern Rockies and Front Range up to the Canadian border and across the north half of the Great Plains, the mid-West, and the shores of the Great Lakes. So the Great Sand Dunes NP occurrences would lie at the southwest corner of this distribution. The species does not follow the Rio Grande drainage out of Colorado.
