Alvar habitat

Alvar habitat is a unique and rare ecosystem characterized by a thin, limestone or calcareous bedrock surface covered with a mixture of grass, herbs, and small plants, often with sparse or no tree cover. It experiences frequent natural disturbances like frost action, fires, and droughts, which prevent woody plants from establishing. This creates an open landscape rich in specialized plant and animal species that thrive in these challenging conditions. Alvars are typically found in regions with limestone bedrock, such as parts of Europe and North America, and are valued for their biodiversity and ecological significance.
