- NEED IN SITU PHOTOS. Bulrush sedge (Carex scirpoidea) has been vouchered four times so far from the Watershed: on a high alpine plateau in the Blue Lake area (Conejos Co, 2001); on a dry alpine meadow above Kite Lake (San Juan Co, 1971); on a dry rolling alpine ridge on the Continental Divide trail (San Juan Co, 1994); in thin soil on a rocky outcrop at the top of Stony Pass (San Juan Co, 2022). Apparently Ackerfield 2022 does not accept these records but BONAP (2025) does. In the lower USA, Carex scirpoidea is present in all Western states except for Arizona and New Mexico, centered mainly in the Rocky Mountains and the north Cascades of Washington State, with uncommon and scattered locations eastward close to the Canadian border from the Great Plains to Maine. The Watershed occurrences are the only ones in the Rio Grande drainage.
