CANADA GEESE WINTER CONCENTRATION: That part of the winter range occupied by loafing/resting Canada geese where densities are significantly greater than the surrounding winter range density. Generally, an extensive area of open water such as large reservoirs, rivers and sloughs that are relatively ice-free and free from human disturbance. CANADA GEESE WINTER RANGE: That part of the overall range occupied by Canada geese from November 1 to March 1. This includes winter loafing/resting and foraging areas.

This information was derived from Colorado Parks and Wildlife field personnel. Data was captured by digitizing through a SmartBoard Interactive Whiteboard using topographic maps and NAIP imagery at various scales (Cowardin, M., M. Flenner. March 2003. Maximizing Mapping Resources. GeoWorld 16(3):32-35). These data are updated on a four year rotation with one of the four Colorado Parks and Wildlife Regions updated each year. These data are not updated on a statewide level annually.
