Global Range: In Florida (three counties), near the Apalachicola River (Cronquist, 1980). Kartesz (1998) includes Alabama in this taxon's range.
Comments: Sandy pinelands (Cronquist, 1980).
Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: 21 - 80
Comments: 27 element occurrence records in Gulf, Liberty, and Franklin counties. The actual numbers of occurrences may be only 22, since the localities of several populations are very close together. Herbarium vouchers from the University of Florida Herbarium (FLAS) have another five occurrences from earlier collections (including one location from Calhoun County).

NatureServe Conservation Status
Rounded Global Status Rank: G3 - Vulnerable
Reasons: Phoebanthus tenuifolius is known from Alabama and from Florida, where twenty-six of the twenty-seven occurrences are in managed areas (in three counties).
Global Short Term Trend: Relatively stable (=10% change)
Comments: Most of the populations occur on United States Forest Service land within the Apalachicola National Forest. Guy Anglin, Botanist for the United States Forest Service, reports that the populations of Phoebanthus tenuifolius within the Apalachicola National Forest appear to be stable (personal communication 1997). The one population in Gulf County, may be declining due to fire suppression (Anglin, personal communication 1997).
Comments: Populations of Phoebanthus tenuifolius within the Apalachicola National Forest face several threats. Fire suppression allows the canopy to close and no light reaches the ground floor. Site preparation for pine plantations causes much damage to the ground layer . Other threats are from cattle grazing and herbicide usage. The Gulf County location has not been burned in several years and the population may be declining (Anglin, personal communication 1997).
