endemic to a single nation
Regularity: Regularly occurring
Type of Residency: Year-round
Global Range: The county records from the Suwanee River southward to Polk and Highlands counties for this species are believed to be the G. cavillaris cavillaris.
Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.
Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: Unknown
Comments: Dunkle (2000) notes that this species is "common" in Florida

National NatureServe Conservation Status
Rounded National Status Rank: N4 - Apparently Secure
NatureServe Conservation Status
Rounded Global Status Rank: G4 - Apparently Secure
Intrinsic Vulnerability: Moderately vulnerable
Comments: Sand-bottomed lakes and their surrounding lands are prime areas for development
Environmental Specificity: Narrow. Specialist or community with key requirements common.
Comments: Sand-bottom lakes
Global Short Term Trend: Unknown
Global Long Term Trend: Unknown
Degree of Threat: High
Comments: The sand-bottom lake habitat for this species is being developed rapidly (Deyrup and Franz, 1994).
Biological Research Needs: Additional studies on the exact distribution of G. c. cavillaris and G. c. brimleyi are needed within Florida as well as their relationship to the G. cavillaris form in North Carolina.
Global Protection: Unknown whether any occurrences are appropriately protected and managed
Needs: Protect the water quality of sand-bottom lakes where this species occurs.
Discourage and prevent input of fertilizers, septic tank leachate, and pesticides into the sand-bottomed lakes (Deyrup and Franz, 1994).
