DEFINITIONS OF MAPPABLE BIOLOGICAL FEATURES Mule Deer and Elk Winter Range - That part of the home range of species where 90 percent of the individuals are located during a site-specific period of winter during the average five winters out of ten (this period is to be defined by CDOW personnel for each DAU). Winter Concentration Areas That part of the winter range of a species where densities are X% greater (defined for each DAU) than the surrounding winter range density during the same period used to define winter range in the average five winters out of ten. Severe Winter Range - That part of the range of a species where 90 percent of the individuals are located when the annual snowpack is at its maximum in the two worst winters out of ten. Production Areas - That part of the home range of a species occupied by the females during a specific period of spring. This period is May 15 to June 15 for elk (only known areas are mapped and this does not include all production areas for the DAU). Highway Crossings - An area within the home range of a species defined by more than six highway mortalities per mile of highway or railroad per year. Migration Pattern A subjective indication of the general direction of the fall movements of migratory ungulate herds. Migration Corridors A specific mappable site through which large numbers of animals migrate and loss of which would change migration routes. Critical Habitat A designation which may be applied to any biological feature mapped for a species, thus indication that within a given DAU, loss of that biological feature would adversely affect that species. Mapping any biological feature does not arbitrarily classify that feature as "critical." Resident Population Area - Areas with distinct populations of a species that fulfill all biological functions within the area identified. Individuals could be found in any part of the area at any time of the year. Summer Range That part of the home range of a species that is not considered Winter Range, including what has tradtionally been known as spring and fall transitional ranges. nsh:1673 DEFINITIONS OF MAPPABLE BIOLOGICAL FEATURES Mule Deer and Elk Winter Range - That part of the home range of species where 90 percent of the individuals are located during a site-specific period of winter during the average five winters out of ten (this period is to be defined by CDOW personnel for each DAU).
