Assessment Notes

Taxonomic notes

Previously assigned as Arthonia wilmsiana Müll. Arg. but changed to Coniarthonia wimlsiana by Grube in 2001.


Why suggested for a Global Red List Assessment?

Due to the lack of information worldwide, and being almost 39 years difference between these two records to Brazil, this might be a rare species. This species should be categorized as Endangered (EN)


Geographic range

This is species is known in 4 countries. In Brazil, only two records are known, one to São Paulo state in 1980, and the other the state of Bahia in 2019.


Population and Trends

There are 12 records in GBIF database, half of them in South Africa, and three to the United States of America.

Population Trend:


Habitat and Ecology

In South Africa, Costa Rica and Australia is found in areas covered with small trees and shrubland, but also in Australia on tree in tropical
rainforest.

Subtropical/Tropical Moist Lowland ForestSubtropical/Tropical Dry Shrubland

Threats

In Brazil, this species is only recorded in the Atlantic Rainforest, at a hotspot threatened by deforestation and wildfire. In the state of Bahia, where the second record was made, the area is a National Park that went into a wildfire in 2019 and receives visitors. Also, indigenous people live there.

Conservation Actions

Even knowing that the area in Bahia state is a National Park, this area still suffering anthropic actions, so there is an urge for educational actions directed to the population near the area. The area in São Paulo state is not a protected area so there are houses and hotels near the area where this species was collected, this area also still suffering anthropic actions.
