Diagnostic Characteristics:
This tufted sedge has leaves that are only 2-4 mm wide and shorter than the stems, the leaf sheaths are green ventrally (front side) almost to the summit and hyaline only at the tip; the female spikes are silvery-green or brown, and ovoid in shape and crowded (overlapping). Achenes are from 0.9mm wide or more and the perigynia ca 2.5 longer than wide - so oval in shape.

Management:
Avoid changes in moisture conditions at the site. These could result from overstory removal or changes in hydrology (stream alteration or impacts due to erosion for example).
