NatureServe Status

Global Status: G2G3
Global Status Last Reviewed: 30Sep2014
Global Status Last Changed: 30Sep2014
Rounded Global Status: G2 - Imperiled
Reasons: This species is restricted to xeric habitats in a relatively small geographic area in north-central Florida, USA. It is a flightless species with presumably low rates of dispersal and recolonization. Very little known about its life history. More information is needed before assigning this species a more definitive rank.
Nation: United States
National Status: NNR

NatureServe Global Conservation Status Factors

Range Extent: 5000-200,000 square km (about 2000-80,000 square miles)
Range Extent Comments: Restricted to sandhill and scrub habitats in Alachua, Gilchrist, Dixie, Levy, Marion, Columbia, Lafayette, Seminole and Suwannee counties in north-central Florida, USA.

Area of Occupancy: Unknown 4-km2 grid cells
Area of Occupancy Comments:  

Number of Occurrences: 6 - 80
Number of Occurrences Comments: Restricted to sandhill and scrub habitats in Alachua, Gilchrist, Dixie, Levy, Marion, Columbia, Lafayette, Seminole and Suwannee counties in north-central Florida, USA.

Population Size: Unknown

Number of Occurrences with Good Viability/Integrity: Unknown

Overall Threat Impact Comments: Destruction of sandhill and scrub habitats in north-central Florida, USA.

Short-term Trend: Decline of 10-30%
Short-term Trend Comments: Sandhill and scrub habitats in Florida are being rapidly destroyed due to agriculture and development with estimates of an average of more than 7000 hectares of scrub and 15,000 hectares of sandhill disappearing every year (Kautz 1993, Kautz 1998).

Long-term Trend: Decline of 30-90%
Long-term Trend Comments: Sandhill and scrub habitats in Florida are being rapidly destroyed due to agriculture and development with estimates of an average of more than 7000 hectares of scrub and 15,000 hectares of sandhill disappearing every year (Kautz 1993, Kautz 1998). On the Lake Wales Ridge, 85% of sandhill and scrub habitats have been lost (Turner et al 2006).

Intrinsic Vulnerability: Highly vulnerable
Intrinsic Vulnerability Comments: Flightless species with a presumably low rate of dispersal.

Environmental Specificity: Narrow. Specialist or community with key requirements common.
Environmental Specificity Comments: This species occurs in sandhill and scrub with open patches of sand.

Other NatureServe Conservation Status Information

Inventory Needs: Survey for presence and abundance in scrub and sandhill habitats in and around its known range in wintertime using fermenting malt or molasses-baited pitfall traps.

Protection Needs: Protect scrub and sandhill habitats in north-central Florida, USA.
