For this report, twenty-two indicators were selected to provide a snapshot of the trends being observed in Arctic biodiversity today. The indicators were selected to cover major species groups with wide distributions across Arctic ecosystems. Special consideration was given to indicators closely associated with biodiversity use by indigenous and local communities, as well as those with relevance to decision-makers. Indicators were also selected on the basis of what was achievable in terms of existing data and in the timeframe available. Each indicator chapter provides an overview of the status and trends of a given indicator, information on stressors, and concerns for the future.
