Description: ElkMigrationCorridors is an ESRI SDE Feature Class depicting Migration Corridors for Elk in Colorado. Migration Corridors is defined as a specific geographic area that facilitates movement between seasonal ranges and receives higher use than the surrounding landscape, relative to herd or population use, and loss of which would disrupt migration. Starting in 2023 and moving forward, Brownian bridge model of movement data, where available, will be included in this layer. This represents a change in the methodology from how these data had previously been generated.This information was derived from Brownian bridge model of movement data and field personnel review. A variety of data capture techniques were used including drawing on mylar overlays at 1:50,000 scale USGS county mapsheets and implementation of the SmartBoard Interactive Whiteboard using stand-up, real-time digitizing at various scales (Cowardin, M., M. Flenner. March 2003. Maximizing Mapping Resources. GeoWorld 16(3):32-35).Updated from data provided by Michelle Cowardin on 10/24/2024

Description: ElkOverallRange is an ESRI SDE Feature Class depicting Overall Range for Elk in Colorado. Overall Range is defined as the area which encompasses all known activity areas within the observed range of an elk population. This information was derived from field personnel. A variety of data capture techniques were used including drawing on mylar overlays at 1:50,000 scale USGS county mapsheets and implementation of the SmartBoard Interactive Whiteboard using stand-up, real-time digitizing 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. The data are not updated on a statewide level annually. Last Regional Updates NE:2022, SE:2021, SW:2024, NW:2023. Calendar date refers to the most current date the data has been published.While a complete data review and the majority of data updates occur during these scheduled Regional Updates, changes to the data in any region may occur annually based on new information obtained through telemetry and field studies. It is recommended that these data be downloaded annually.

Description: ElkResidentPopulationArea is an ESRI SDE Feature Class depicting resident population areas for elk in Colorado. This dataset represents Elk Resident Population Areas which are defined as an area used year-round by a population of elk. Individuals could be found in any part of the area at any time of the year; the area cannot be subdivided into seasonal ranges. It is most likely included within the overall range of the larger population. This information was derived from field personnel. A variety of data capture techniques were used including drawing on mylar overlays at 1:50,000 scale USGS county mapsheets and implementation of the SmartBoard Interactive Whiteboard using stand-up, real-time digitizing 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.

Description: ElkSevereWinterRange is an ESRI SDE Feature Class that shows severe winter range for elk in the state of Colorado. This dataset represents that part of the overall range of elk where 90% of the individuals are located when the annual snowpack is at its maximum and/or temperatures are at a minimum in the two worst winters out of ten. The winter of 1983-1984 is a good example of a severe winter. This information was derived from field personnel. A variety of data capture techniques were used including drawing on mylar overlays at 1:50,000 scale USGS county mapsheets and implementation of the SmartBoard Interactive Whiteboard using stand-up, real-time digitizing 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.
