Alvar landforms

Alvar landforms are unique, flat landscapes primarily found in regions like the Great Lakes area of North America and parts of Northern Europe. They are characterized by their limestone or dolostone bedrock, which is often exposed due to thin soil cover. Alvars feature a mix of grasslands and sparse forests, supporting specialized plants and animals adapted to these conditions. These environments are important for biodiversity and are considered rare due to their specific geological and climatic conditions. Alvar landscapes often show seasonal changes and are maintained by natural processes like drought and grazing.
