Regularity: Regularly occurring
Global Range: A Southeastern Coastal Plain endemic, ranging from southeastern North Carolina south to central Florida and west to southern Alabama (Godfrey and Wooten 1979, Weakley 1996).
Plants are slenderly rhizomatous and loosely colonial. The axils of the panicle branches and of the spiklets are glabrous. Spikelets mostly 10 mm wide and 15 mm long or so (Godfrey and Wooten 1979).
Comments: Stream and river banks, low moist to wet woodlands, often very abundant in wet hammocks, adjacent ditches and clearings (Godfrey and Wooten 1979). Blackwater swamp forests (Weakley, 1996).
Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: 21 - 80
Comments: Chasmanthium nitidum occurs in five states: North Carolina, South Carolina, Georgia, Alabama, and Florida. There are two occurrences in one county in North Carolina. Documented with herbarium specimens for five counties in Georgia and 28 counties in Florida.
National NatureServe Conservation Status
Rounded National Status Rank: N3 - Vulnerable

Rounded Global Status Rank: G3 - Vulnerable
Reasons: An estimate of the number of occurrences is below 100. This Southeastern Coastal Plain endemic is rare at the northern and westermost edges of its range in North Carolina, South Carolina and Alabama. It is documented for 28 counties in Florida, but some of the records are based on specimens over 20 years old and the occurrences may no longer exist. It may be threatened by logging, intensive forestry practices, and invasive exotic species.
Global Short Term Trend: Relatively stable to decline of 30%
Global Long Term Trend: Decline of 10-50%
Degree of Threat: Low
Comments: It may be threatened by logging, intensive forestry practices, and invasive exotic species.
Relevance to Humans and Ecosystems
Stewardship Overview: Maintain mixed or deciduous forest cover where this plant occurs, avoid conversion of the forest to intensive pine plantation. In cases where logging has occurred, avoid bedding for reforestation site preparation, herbicides used for site preparation should be compatible with native grasses. In some cases invasive exotic plants may threaten populations, and control of the invasive exotic plants would be warranted. This control should be done in a way that does not negatively impact this unusual grass.
