Alvar Biome

The Alvar biome is a unique landscape characterized by flat, grassy areas with thin soils over limestone or dolostone bedrock. Often found in regions like the Great Lakes of North America and parts of Scandinavia, Alvars support a diverse range of plant and animal species adapted to harsh conditions, including drought and grazing. They feature a mix of prairie-like grasses and wildflowers, alongside sparse tree growth. Alvers are important for biodiversity and serve as habitats for many rare species. However, they face threats from development, agriculture, and invasive species, making conservation efforts crucial.
