Name: (Potamogeton diversifolius, Stuckenia filiformis) Permanently Flooded Herbaceous Alliance Reference: Western Ecology Working Group of... Description: The permanently flooded wetlands in this alliance occur in north-central and southeastern Colorado in two very different habitats. These wetlands are dominated by hydromorphically rooted herbaceous species. One habitat dominated by Stuckenia filiformis (= Potamogeton filiformis) occurs in shallow, montane lakes in north-central Colorado, elevation is 2060-2530 m. The climate is cool, with a relatively short growing season. The mean annual precipitation is 20-40 cm, mostly falling as snow. These lakes get water primarily from snowmelt-fed streams. The other habitat dominated by Potamogeton diversifolius is found in the canyons of southeastern Colorado, growing in plunge pools in sandstone bedrock. The elevation is usually between 1100-1850 m. Climate is semi-arid with hot summers and cold winters. The mean annual precipitation is 25-35 cm, mostly falling during the growing season. These pools fill up with runoff during summer thunderstorms. Both are permanently flooded; however, the water level in the plunge pools can vary greatly during the year. The herbaceous layer in the montane wetlands is dominated by the submerged plant Stuckenia filiformis, which often grows in dense mats. Associated immersed plants include Sagittaria cuneata and Polygonum amphibium var. emersum (= Persicaria amphibia var. emersa). This wetland is found in open water surrounded by Carex and Scirpus marshes growing out from the shore. The bedrock plunge pool wetlands have been described from canyons where pools form in the sandstone bedrock. They are dominated by Potamogeton diversifolius, another hydromorphically rooted, submerged forb. Little is known about these wetlands.  Accession Code: VB.CC.24439.POTAMOGETONDIVE Plot-observations of this Community Concept: 0
