About Lichens

(Click on image for larger view)

Lichens number ~1000 species and live in almost every habitat in Nova Scotia. Suites of species frequently grow together to form distinct lichen communities. Many species are common, while others are rare or threatened. The latter are often at the edge of their global distribution ranges or are threatened by habitat loss, pollution and other human-related factors. For a few species, Nova Scotia provides some the best available habitat in the world.
