02Description

Species Profile

Species profile data sourced from the IUCN Red List of Threatened Species.

Aspicilia aquatica faces severe threats from habitat degradation due to water pollution, eutrophication, and altered hydrology of freshwater systems. Climate change and increased frequency of extreme weather events further threaten the specialized aquatic environments this lichen requires, while its limited distribution makes populations particularly vulnerable to local extinctions.

03Habitat

Habitat & Distribution

This aquatic lichen species inhabits rocks and substrates in clean, fast-flowing freshwater streams, rivers, and occasionally lake margins. It requires specific water chemistry conditions and is typically found in oligotrophic waters with low nutrient levels and high oxygen content.
