Assessment Status Notes

Taxonomic notes


Why suggested for a Global Red List Assessment?

Anzia colpodes (Common Name: Black Fringe Foam Lichen) is endemic to eastern North America where it is widespread. The species has been extirpated from large portions of its range and remaining populations in many areas appear to be in decline.


Geographic range

Anzia colpodes was historically widespread and common in temperate eastern North America. It is still widespread but has been extirpated or suffered significant declines in many areas where it once occurred.


Population and Trends

Demographic studies are needed to assess and monitor populations sizes. Considering the extensive extirpation of the species historically we are ranking the population trend a deteriorating.

Population Trend: Deteriorating


Habitat and Ecology

This species occurs on the bark of hardwoods, and more rarely conifers, in humid forested habitats throughout temperate eastern North America.

Temperate Forest

Threats

The primary threats to this species stem from 1) extensive historical extirpation and population declines, 2) changes in habitat (macro- and micro- scales) resulting from deposition of pollutants and altered ecosystem, and 2) changes in habitat (macro- and micro- scales) that are likely to result from climate change, 3) changes in habitat (macro- and micro- scales) resulting conversion and deterioration of natural habitats both historically and ongoing.

Conservation Actions

This species is currently being considered to listing by COSEWIC in Canada. There are many conservation actions that can be taken including 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, improving air quality regulation, and providing increased protection for forest stands where the species occurs.

Research needed

The distribution of this species is well understood. 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.
