ENFuscopannaria confusa
Fuscopannaria confusa faces severe decline primarily due to air pollution and habitat degradation affecting the old-growth forests where it occurs. As a lichen species highly sensitive to atmospheric changes, it is particularly vulnerable to nitrogen deposition, sulfur compounds, and other airborne pollutants that alter its substrate chemistry and disrupt symbiotic relationships.
forskrimmerlav
CRRinodina endophragmia
Rinodina endophragmia is critically endangered primarily due to habitat loss and degradation of its specialized lichen habitat. Air pollution and climate change are additional stressors affecting this rare lichen species. The species has an extremely limited distribution, making it particularly vulnerable to local environmental changes.
forspåskrislav
CRStereocaulon coniophyllum
Stereocaulon coniophyllum, a lichen species, faces severe threats primarily from habitat degradation and climate change impacts on its specialized arctic and subarctic environments. Air pollution, particularly nitrogen deposition and sulfur compounds, significantly affects lichen communities by altering their sensitive physiological processes. The species' extremely limited distribution and slow growth rates make it particularly vulnerable to environmental changes.
Fortified Carpet
VUScotopteryx moeniata
fosseringlav
CRRinodina stictica
Rinodina stictica, a crustose lichen species, faces severe decline primarily due to air pollution and habitat degradation. This species is particularly sensitive to atmospheric pollutants and changes in air quality, which directly impact its ability to photosynthesize and survive. Urban development and industrial activities have significantly reduced suitable habitat and increased pollution levels in areas where this lichen historically occurred.
