Species Assessment Summary and Watch List

Map of major habitats of North America.

This table summarizes our assessment of the 1,154 native species in Canada, the U.S., and Mexico. It lists the conservation concern score for every species (see Methods for a description of the score). We also list the primary breeding habitat and the primary region in which migratory species spend the northern winter. Nonmigratory species are listed as Resident. Species with “(Wet)” after the habitat category are found in wetland habitats embedded within that habitat type.

The Watch List includes 432 species with concern scores of 14 or higher, or with a concern score of 13 and a steeply declining population trend—these are the species most at risk of extinction without significant conservation actions to reverse declines and reduce threats.

Terms in the Breeding Habitat column correspond with the map of major habitats at right. Temperate Forests include Eastern and Western Temperate Forest; Tropical Highland Forests include Tropical Cloud Forest, Mexican Pine-Oak, and Mexican Highland Forests; Tropical Lowland Forests include Tropical Dry Forest and Tropical Evergreen Forest. Species occurring in three or more major habitats are considered Generalists.
