Assessment Status Notes

Taxonomic notes


Why suggested for a Global Red List Assessment?

Fissurina ilicicola is endemic to the Mid-Atlantic Coastal Plain of eastern North America where it occurs in low-lying swamp forests that are imperiled by sea-level rise and other forces.


Geographic range

Fissurina ilicicola is known from a small number of locations in the Coastal Plain of Georgia and Florida in southeastern North America. Extensive fieldwork in the southeastern United States has failed to locate additional populations of the species.


Population and Trends

Demographic studies are needed to assess and monitor populations sizes. Our current knowledge of the species suggests that its populations are stable.

Population Trend: Stable


Habitat and Ecology

This species occurs on the bark of American holly (Ilex opaca) in forests in humid, low-lying river drainages and coastal swamps.

Temperate Forest

Threats

In addition to intense pressure from development and other forces (industry, urbanization), much of the remaining habitat in the region where this species occurs is imperiled by sea-level rise. Additional threats include pollution, road expansion and maintenance, logging and other threats that would further degrade the remaining high quality natural habitats.

Conservation Actions

There are many conservation actions that can be taken including increasing protected areas in size and preventing further habitat degradation, educating and training land managers and local botanists to identify the species so we can monitor its health, federally listing the species as endangered in the United States, and improving air quality regulation, monitoring changes associated with sea-level rise. Policy and legislation considering biodiversity threatened by sea-level rise is also needed.

Research needed

Further research that will aid in the conservation of this species includes population assessments and monitoring, population genetics studies, and ecological studies that incorporate threats to the species. Additionally, a species recovery plan needs to be written.
