Threat ImpactHigh

Range Extent1000-5000 square km (about 400-2000 square miles)

Number of Occurrences6 - 80

Rank Reasons

A very restricted range in the Florida panhandle - Liberty, Franklin, Bay, and Gulf counties, Florida. Most of the largest populations are protected on the Apalachicola National Forest; populations on private land (formerly St. Joe Paper Co. lands) have not been observed since the late 1980's. Habitat in these private lands is decreasing in quality and extent due to fire exclusion, conversion to improved pasture, drainage, and clearcutting.

Range Extent Comments

2,163 sq km calculated in GeoCat. Known from the Apalachicola region of the Florida panhandle from Liberty, Bay, Franklin and Gulf counties.

Occurrences Comments

29 occurrences as of 2019 but 10 occurrences are likely not extant. Based on recent surveys within range and habitat of the species.

Threat Impact Comments

The primary threat to this species is habitat loss/degradation as a result of conversion to pine plantations and/or pasture. Establishment of pine plantations often leads to changes in the habitat that Scutellaria floridana cannot withstand after the first few years, including changes to drainage, crowding by introduced grasses, and shading due to fire suppression. Use of ORVs occurs in nearby habitats and could affect unprotected S. floridana populations

Ecology & Habitat

Habitat

Dark, humus rich sands of pine-palmetto flatwoods, wet prairies, and savannahs. (Based on Kral 1983) Seepage slopes.
