Alvar habitats

Alvar habitats are unique ecosystems characterized by a thin, white limestone or granite surface with sparse vegetation, usually found in northern regions like Scandinavia. These areas consist of a delicate balance between exposed bedrock and patches of grasses, mosses, and wildflowers. Alvars support specialized plants and animals adapted to harsh, well-drained conditions, often thriving in the cracks and thin soils. They are important for biodiversity, cultural heritage, and serve as valuable natural habitats. Due to their rarity and sensitivity, alvars require careful conservation to preserve their distinct ecological features.
