Status, Habitat, and Distribution of Schoenoplectiella hallii (Cyperaceae) in Texas.

Schoenoplectiella halli (Gray) S.G. Sm. is an annual sedge in the Cyperaceae family with a rounded conservation status of G2 occurring in very sparse and scattered populations across the Eastern and Midwestern United States. Schoenoplectiella hallii is typically found in ephemeral ponds or other fluctuating shorelines with little perennial competition, and entire populations are known to disappear for decades at a time only to reemerge in staggering numbers. There is only one known population in Texas in the Lyndon B. Johnson National Grasslands. Unlike other populations, this population remains year after year and occurs in quite a different climate than all other known sites. At the LBJ site we recorded population size, GPS coordinates, and the state (fertile, sterile, dead) of each plant and performed habitat surveys. This data was used to further characterize the habitat and associates of S. hallii and to assess the current conservation status of the species in Texas. We also compared our data to information on the species in other states and determined what makes Texas an ideal habitat for S. hallii and what the national outlook for the species may be in the future.
