Assessment Status Notes

Taxonomic notes


Why suggested for a Global Red List Assessment?

Rinodina brodoana (common name: Ernie’s Mountain Treasure) is endemic to the southern Appalachian Mountains where it is known only from two populations in mature old-growth low to middle elevation hardwood forests. We assert this species merits ranking due to the limited known geographic range, small number of known extant populations (two), and the small number of individuals known (<50).


Geographic range

The species is restricted to a small region within the southern Appalachian Mountains in North Carolina, U.S.A.


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

The species is restricted to mature middle and low elevation hardwood forests where it only is known to occur on the boles of large, mature hardwoods.

Temperate Forest

Threats

The threats to this species are habitat changes (macro- and micro- scale) as a result of climate change.

Conservation Actions

There are many conservation actions that can be taken including monitoring for changes in microhabitats/microclimates that might impact the species, 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.

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.
