The Arctic Species Trend Index (ASTI) is an index that tracks trends in over 300 Arctic vertebrate species and comprises the Arctic component of the Living Planet Index.

It is important to identify how wildlife and ecosystems are changing in order to develop effective conservation and adaptation strategies in the Arctic, an environment undergoing dramatic changes.

The ASTI describes overall trends across species, taxonomy, ecosystems, regions and other categories. Learn more about the ASTI, including key findings and facts, trends and sample populations, and explore the Circumpolar Biodiversity Monitoring Program, that commissioned the ASTI in cooperation with partners.
