Alvar species

Alvar species are plants and animals that live specifically in alvar habitats—unique, fragile landscapes characterized by limestone or dolomite bedrock with thin soil layers. These environments often feature a mix of grasslands, shrubs, and rare plant communities, supporting specialized and sometimes endangered species. Because alvars are sensitive and rare, the species found there have adapted to thrive in shallow soil conditions and withstand particular environmental stresses. Protecting alvar species is important for maintaining biodiversity and the health of these distinctive ecosystems.
