NatureServe Status

Global Status: G3
Global Status Last Reviewed: 07May1999
Global Status Last Changed: 12May1988
Rounded Global Status: G3 - Vulnerable
Reasons: Sizeable number of extant populations. Still found through most of historical range. A few properties offer protection. Well-defined threats. Likely to be documented from many more sites, with specific searches.
Nation: United States
National Status: N3

U.S. & Canada State/Province Status

NatureServe Global Conservation Status Factors

Range Extent Comments: Andropogon arctatus occurs in a total of 23 counties in Florida - 11 with current EOs and 12 without. In Alabama, it is known from only two counties - currently in Covington, historically in Geneva. There is a specimen from Pamlico County, North Carolina, annotated by C. Campbell, an expert on this genus. Regardless of the correctness of the specimen's identity, its provenance (whether native or introduced) is highly questionable. In Florida, A. arctatus occurs from Leon County westward and from Brevard County southward, leaving a large area in the northeastern portion of the state in which it is nearly absent (records in Alachua and Clay Counties only). This anomaly needs explanation, for suitable habitat is certainly present.

Number of Occurrences: 21 - 80
Number of Occurrences Comments: In Florida, there are about 40 current EOs in at least 11 counties (some with multiple EOs) and historical EOs in at least 12 other counties. The number of EOs on Eglin Air Force Base is subject to review and may bring the Florida total down a bit. Alabama has two current EOs.

Population Size Comments: Populations sometimes large.

Overall Threat Impact Comments: Conversion of habitat (to pine plantations, suburban development, agriculture) and fire suppression are the major threats.

Short-term Trend: Decline of 10-30%
Short-term Trend Comments: Since this is a species that inhabits fire-prone and fire-dependent habitats, it is assumed to be declining.

Intrinsic Vulnerability Comments: Periodic fire necessary to maintain open habitat; cannot tolerate drainage or severe soil preparation.

Ecology & Life History
Help
Basic Description: Perennial grass up to 1.5 meters tall, leaves long and narrow and tending to curl; spikelets (small flowering/fruiting structures) are numerous and occur along paired racemes (finger-like branches) that grow from many sheaths (elongate collars) along the stems. The flowers are densely covered with tawny hairs.
Reproduction Comments: Plumed seeds of the genus are wind-dispersed (Campbell 1983).
Habitat Comments: The primary habitat is wet pine flatwoods that are subjected to recurring fires. Over most of the range of A. arctatus, longleaf pine is the canopy dominant, or is co-dominant with slash pine; in the southernmost end of the range, slash pine is sole dominant. Loblolly pine may co-occur in the northwestern portion of the range. Understory hardwoods tend to be scattered or even absent, but may include Quercus nigra, Magnolia virginiana. The shrub layer is usually well-developed and supports combinations of the following: Ilex glabra, Clethra alnifolia var. tomentosa, Gaylussacia tomentosa, Vaccinium myrsinites, Quercus minima, Q. pumila, Kalmia hirsuta, Serenoa repens, Myrica cerifera var pumila. The herb layer is well developed and usually contains southern wiregrass, other Andropogons, Schizachyrium spp., Anthaenantia rufa, Panicum rigidulum, P. verrucosum, Aristida spp.

Secondary habitats include seepage wetlands (pitcher plant bogs) and wet pine savannas. The former are wetter than flatwoods and harbor pitcher plants and many sun-loving herbs. The latter share the same moisture regime as flatwoods, but shrubs are far less common and grasses and herbs more abundant.
