Diagnostic Characteristics:
Carex crawei is a small sedge usually less than 1 dm (although it may be up to 3 dm). It has a distinctive pale green color to the leaves and these are slightly recurved and stiff. It is associated with thin soils that are usually moist in the spring. It is rhizomatous with a 3-sided achene and perigynia; the perigynia has a short straight beak, rounded base and several raised veins.

Management:
Woody plant invasion may need to be controlled using periodic prescribed fire, mowing or other means, although this glade habitat is often naturally maintained by thin soils. Timber removal may be beneficial. Hand removal of trees in the vicinityof the plants is needed to avoid impacts from woody plant removal. Soil disturbance such as ATV trails or timber removal or any activity that results in increased erosion and weed invasion will be detrimental. Exotic pest plants are a threat to this species


Global Range:
