Rinodina fimbriata

Local name: sjökrimmerlav

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Rinodina fimbriata faces severe threats from air pollution and acid rain, which directly damage its sensitive lichen thalli and disrupt the delicate chemical balance required for survival. Habitat loss through coastal development and climate change-induced alterations to its specialized maritime environment further threaten remaining populations.

Threat summary

Habitat

Maritime coastal environments, particularly on rocks, concrete structures, and other hard substrates in salt-spray zones near the sea. Typically found in areas with high humidity and regular exposure to marine aerosols but protected from direct wave action.
