Assessment Notes

Taxonomic notes

This species was originally included within Lepraria normandinoides as a chemical variant, however molecular data demonstrated that it should be recognized as a distinct species (Lendemer 2012).


Why suggested for a Global Red List Assessment?


Geographic range

Lepraria oxybapha is endemic to North America where it is widespread in temperate eastern North America, with disjunct populations in montane southwestern North America (Lendemer 2012, 2013).


Population and Trends

Detailed population data are unavailable for this taxon. However, it is suspected to be stable as it is common and widespread in many different habitats (Lendemer 2013, Tripp & Lendemer 2020). There is no indication the species is restricted to a narrow range of habitats or substrates.

ASSESSMENT: Least Concern
Given the large number sites where it is extant, large geographic range, large population size, and absence of documented or suspected declines, the species does not meet the thresholds for any threat criteria.

Population Trend: Stable


Habitat and Ecology

Lepraria oxybapha grows on the bases and boles of trees, as well as sheltered and protected surfaces of non-calcareous rocks. It occurs throughout a broad range of forested habitats, elevations and habitat qualities across its range.

Threats

The primarily threat to this species is urbanization as it does not typically occur in urban areas. Otherwise it appears to be tolerant of disturbance.

Conservation Actions

Many sites where Lepraria oxybapha is found are located on public lands and protected areas where it is incidentally protected. This species would benefit from broader awareness and training as to the impacts of urbanization generally on lichens.

Research needed

This species would benefit from demographic studies and long-term monitoring of both habitat and population trends.
