Species Profile
Punctelia stictica is a species of foliose lichen in the family Parmeliaceae. It is widely distributed lichen, recorded in Africa, Europe, North America, South America, and Greenland. It is typically found growing on rocks.
Bruin stippelschildmos faces significant threats from air pollution, particularly nitrogen deposition and sulfur compounds, which alter the chemical composition of its substrate and reduce lichen diversity. Habitat loss through deforestation and urban development further restricts available suitable surfaces, while climate change affects the delicate moisture balance required for this epiphytic species.
Key Facts
Habitat & Distribution
This epiphytic lichen species grows on the bark of deciduous and coniferous trees in mature forests, woodland edges, and parklands. It typically occurs in areas with moderate to high humidity and clean air conditions, often found on oak, maple, and other broad-leaved trees with textured bark.
Threats
Air pollution and acid deposition
Habitat loss from deforestation
Agricultural intensification and pesticide drift
Climate change affecting moisture regimes
Urban development and infrastructure expansion
