NatureServe Status

Global Status: G1
Global Status Last Reviewed: 17Sep2010
Global Status Last Changed: 18Dec1998
Rounded Global Status: G1 - Critically Imperiled
Reasons: Rediscovered in northeast Alabama in 1994. In Texas, only known from two historical sites; the last time it was seen was 1953. Most of its habitat in Texas has been altered; the forested land has become pine plantations and the grasslands have become pastures. Threatened by change in land use.
Nation: United States
National Status: N1

U.S. & Canada State/Province Status
Due to latency between updates made in state, provincial or other NatureServe Network databases and when they appear on NatureServe Explorer, for state or provincial information you may wish to contact the data steward in your jurisdiction to obtain the most current data.

NatureServe Global Conservation Status Factors

Range Extent Comments: Rediscovered in St. Clair County, Alabama in 1994. Historically known from Angelina County, Texas (Poole et al. 2007). Falsely reported from Virginia, Georgia, and Arkansas (Kartesz 1999).

Area of Occupancy: 3-125 4-km2 grid cells
Area of Occupancy Comments: Approximately five to twelve 4-sq km grid cells.

Number of Occurrences: 1 - 20
Number of Occurrences Comments: Approximately five to twelve occurrences in Alabama (EO data in the NatureServe central database as of 2010, A. Schotz, pers. comm., 2010).

Population Size Comments: Approximately 100 individuals estimated (A. Schotz, pers. comm., 2010).

Overall Threat Impact: Medium
Overall Threat Impact Comments: Landscape fragmentation that would alter natural processes such as naturally occurring fire that historically burned along the periphery of the glades is a threat (A. Schotz, pers. comm., 2010). This species frequently occurs along glade margins and may need some fire to promote growth and reproduction. Potentially threatened by changes in land use including clear-cutting for agriculture or urban development (Alabama Natural Heritage Program 1994). Other threats include use of habitat as staging areas for logging operations, trash dumping, and ATV activity (A. Schotz, pers. comm., 2010).

Ecology & Life History
Help
Basic Description: A trailing, rhizomatous, deciduous shrub, up to 3 m tall, with glossy, more-or-less oblong leaves that taper toward the base and are shallowly 3-5 lobed at the tip.
Palustrine Habitat(s): FORESTED WETLAND, Riparian
Terrestrial Habitat(s): Forest - Mixed, Forest/Woodland, Grassland/herbaceous, Shrubland/chaparral
Habitat Comments: In Alabama, this species occurs in sandstone glades within a matrix of pine-oak-hickory forest (A. Schotz, pers. comm., 2010). In Texas, it was found in the shrub layer of loblolly pine (Pinus taeda)-oak forests on deep sandy soils in creek bottoms and possibly also in shallower soils of upland prairies (Poole et al. 2007).

Management Summary
Help
Stewardship Overview: Protect and maintain habitat in a landscape context that would allow fire and other natural processes to take place (A. Schotz, pers. comm., 2010). Prevent logging. Avoid alterations to hydrology that would cause rocky bluff habitat to be inundated. Further document the species' status and monitor trends.
