Abstract
Habitat characteristics of wetlands that contain the federally endangered sedge,Scirpus ancistrochaetus, were investigated in a one-point-in-time field survey. Sixteen adjacent seasonal ponds, four of which supported populations ofS. ancistrochaetus. were sampled for 26 habitat variables. Using only five of these variables, we were able to separate ponds with and withoutS. ancistrochaetus in a linear discriminant analysis. These five variables are wetland area, percent cover of overlying forest canopy, soil percent organic matter, soil exchangeable [Na], and water [H−]. Ponds containingS. ancistrochaetus had higher soil organic matter content, highet soil [Na], greater area, lower water [H+], and lower percent forest canopy cover compared to ponds that did not support this species. This information can be used toward understanding factors that control the distribution of this species and also toward evaluating possible habitat for reintro-duction of this endangered species.
