Name: A.1746
Reference: EcoArt 2002
Description: This hydromorphic vegetation type of California occurs in seasonal to permanent, freshwater wetlands. Water is still or slow-moving. Stands of this alliance are found on stream and lake margins, in vernal pools, ponds, and marshes. Elevational ranges vary from sea level to 1500 m. This alliance is dominated by species of ~Isoetes$. The specific species are dependent on elevation and duration of inundation. Lower elevation stands with semi-permanent flooding are likely to be dominated by ~Isoetes howellii$ and/or ~Isoetes orcuttii$. Montane lakes and ponds are likely to be dominated by ~Isoetes bolanderi, Isoetes tenella (= Isoetes echinospora)$, and/or ~Isoetes occidentalis$. ~Isoetes nuttallii$ may occur along stream margins. Quillworts may be the dominant plants on lake and pond bottoms.
