Conradina glabra

This rare mint, the Apalachicola rosemary, was listed as federally endangered in 1993. At that time, there were seven known locations of this species, six of which were on private timber company land. Since that time, the one population on State land has disappeared, but The Nature Conservancy discovered two new locations in or adjacent to one its preserves, and an exciting reintroduction effort was carried out.

This Florida-endemic mint is a perennial shrub that grows to a height of 0.8 meters. The Apalachicola rosemary has linear, aromatic evergreen leaves. The upper surface of these leaves is smooth and hairless, while the lower surface is covered with dense hairs that are visible only with magnification. The flowers are white to pale lavender-pink flowers with a band of purple dots on the white throat. Flowers arise from the leaf axils in groups of 2 or 3.

Distribution & Occurrence

Top

State Range

Florida

Habitat

In Liberty County it occurs in flat sandy areas(characterized by longleaf pine and turkey or bluejack oak) that are deeply dissected by steep sided, moist ravines (Gray, 1965) Since Shinners did not determine this species to be taxonomically distinct until 1962, no one is sure of its exact habitat before the conversion of pine plantations in the 1950s. More recent occurrences have been found on the upper edge of steepheads in the transition to sandhills, edges of pine plantations, highway and utility right-of-ways (FNAI 2000).

Not much is known about the Santa Rosa County population.

Distribution

Endemic to Liberty and Santa Rosa Counties, Florida (Coile 2000).

Number Left

7 ? sites (1 protected). This species is restricted to areas near the Apalachicola River west of Tallahassee in Liberty Co., FL.

Ecological Relationships

No ecological associations known for this species.

Threats

Main threats to this species come from logging and conversion of its habitat for silviculture practices. Other threats include loss of suitable habitat from invasive species and fire suppression (fire is needed to maintain the historically open habitat where this plant occurs). (Gordon 1996)

Current Research Summary

� Penny Isom of the Division of Forestry is conduction pollen transfer studies at Apalachicola Bluff and Ravine Preserve.
� Greg Seamon of Apalachicola Bluff and Ravine Preserve is monitoring this species.
� An successful, experimental reintroduction took place beginning in the late 1980's. This work was a collaboration between the Center for Plant Conservation, Bok Tower Gardens, and The Nature Conservancy. (Gordon 1996)

Current Management Summary

Natural and reintroduced populations on The Nature Conservancy's Preserve are being monitored and management practices are in place, including prescribed burns.

Research Management Needs

� Determine current distribution.
� Protect and enhance existing populations.
� Monitor existing populations.
� Educate the public.
� Prevent degradation of existing habitat by removing competing vegetation.
� Restore areas to suitable habitat.
� Conduct habitat-level research projects.
� Monitor habitat/ecological processes.
� Germination and propagation techniques.
