NatureServe Status

Global Status: G2
Global Status Last Reviewed: 07Aug2014
Global Status Last Changed: 31Jul2003
Ranking Methodology Used: Ranked by calculator
Rounded Global Status: G2 - Imperiled
Reasons: Narrow ranging species occuring in Texas, Georgia and Florida. Most site have less than 20 plants but it is abundant at a few locations in Florida. Threatened by road maintanence activities, alterations to hydrology, forestry practices, and recreational activities.
Nation: United States
National Status: N2

U.S. & Canada State/Province Status

NatureServe Global Conservation Status Factors

Range Extent Comments: Occurs in southeastern Texas, northern Florida, and southeastern Georgia.

Area of Occupancy: Unknown 4-km2 grid cells
Area of Occupancy Comments: Texas:"It was once locally common but restricted to wetland pine savannahs in the Big Thicket area but now is limited to a few sites in Tyler County.

Florida: "Paul was out in the Apalachicola NF this weekend and found 1000s of plants in a population that was formerly thought to be P. ciliaris. But like a lot of our north Florida species, the plants may be numerous but very limited in range" Linda Chafin

Number of Occurrences: 6 - 80
Number of Occurrences Comments: There are three sites in Tyler County, Texas. It is unknown how many extant sites are in Florida where it is thought that over 90% of the range is found. It is documented in Apalachicola and Osceola National Forests and some sites outside of national forests (Brown 2003). Florida sites documented (including historic) in Liberty, Franklin, Wakulla Jefferson, Taylor, Columbia, Union, Baker, Duval, Clay, and Marion counties. Numerous extant sites in Georgia (Richards and Sharma 2014).

Number of Occurrences with Good Viability/Integrity: Very few (1-3)

Overall Threat Impact: High
Overall Threat Impact Comments: Habitat loss and degradation due to development has threatened most of the Texas populations. Florida populations occur on protected lands. Fragmentation of populations and intrinsic vulnerability are also threats. Threats to roadside sites include injury or destruction by mowing, herbicides, or crushing by heavy machinery (Richards and Sharma 2014).Threats on public forestland include logging and recreational activities (ORVs), and ditching and draining of lands. Most sites in Florida are on public forestland or roadsides in Georgia. Damage to plants by destructive land management practices has been documented in Georgia in the three counties Camden, Charlton, and Brantley Counties (Richards and Sharma 2014). Although there is no evidence that species is being collected it is a showy orchid species and this could change.

Short-term Trend: Unknown
Short-term Trend Comments: Only recently recognized as a distinct species, recent (2002 & 2003) surveys have found few to 1000s of plants in Florida and Texas. Most occurrences are on protected lands.

Long-term Trend: Decline of <70% to Relatively Stable
Long-term Trend Comments: Always restricted, the extent of occurrence in Texas is significantly reduced. Florida populations are difficult to track because of taxonomic confusion.
