Anzia ornata (Common Name: Ornate Foam Lichen) occurs in southeast Asia and southeastern North America. The species is rare in both regions and many populations in North America area threatened by a host of factors including sea-level rise.

Anzia ornata occurs in southeastern Asia and southeastern North America.

Demographic studies are needed to assess and monitor populations sizes, however this species is considered rare throughout its range.

This species occurs on the bark of hardwoods, and more rarely conifers, in humid forested habitats.

The primary threats to this species stem from 1) changes in habitat (macro- and micro- scales) resulting from deposition of pollutants and ecosystem alterations, 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, and 4) loss of its core range in North America as a result of sea-level rise.

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.

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.
