Justification

Parmeliopsis ambigua is a very widespread and often abundant species across many countries and does not meet any of the criteria for threat levels; it is, therefore, listed as Least Concern.

Geographic range

Parmeliopsis ambigua is pan-temperate to circumboreal, extending to the southern Arctic and the mountains of south-eastern Australia, occurring also at higher elevations in southern latitudes from North America, Europe and adjacent north Africa and Asia.

Population and Trends

This species is widespread and abundant across high latitudes and on mountains at lower latitudes, and the population is inferred to be stable.

Population Trend: Stable

Habitat and Ecology

This small rosette-forming lichen is found on acidic bark and wood, especially of conifers, but also on other trees with acid bark. It is found in open and shady forests, often on tree bases, old wood, stumps and logs, and sometimes on sandstone.

Threats

It is not thought to face any significant threats.
