Species Season

The Trend Maps tool allows you to produce a map showing regional population trends for a selected species and season. Trends are calculated using the same period among sites (usually the 10 most recent years available). Only sites or regions with sufficient data are presented. To see more details about the trend at a site or region, simply click on a symbol. For more information about maps, click here.
