<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>BighornMigrationCorridors [BSMC] is an ESRI SDE Feature Class showing a specific, mappable site through which large numbers of animals migrate, and the loss of which would change migration routes. </SPAN></P><P><SPAN>BighornMineralLick [BSML] is an ESRI SDE Feature Class showing specific, natural sites known to be utilized by bighorn sheep for obtaining minerals to meet basic nutritional needs. </SPAN></P><P><SPAN>BighornOverallRange [BSOV] is an ESRI SDE Feature Class showing Overall Range for Bighorn Sheep in Colorado. Overall Range is defined as the area which encompasses all known activity areas within the observed range of a population. </SPAN></P><P><SPAN>BighornProductionArea [BSPA] is an ESRI SDE Feature Class showing production (lambing) areas for bighorn sheep in Colorado. Production areas are defined as that part of the overall range occupied by pregnant females during a specific time period in the spring. This time period is May 1 to June 30 for Rocky Mtn bighorn sheep, and February 28 to May 1 for desert bighorn sheep. Only known production areas are mapped. </SPAN></P><P><SPAN>BighornSevereWinter [BSSWR] is an ESRI SDE Feature Class showing that part of the winter range where 90% of the individual animals 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. Not all populations exhibit migratory behavior during severe winters, many will stay within the defined winter range regardless of conditions. Thus, some populations may not have a mapped severe winter range distribution. </SPAN></P><P><SPAN>BighornSummerConcentration [BSSCA] is an ESRI SDE Feature Class showing Summer Concentration Areas for Bighorn Sheep in Colorado. Summer Concentration Area is defined as those areas where bighorn sheep concentrate from mid-June through mid-August. High quality forage, security, and lack of disturbance are generally characteristic of these areas to meet the high energy demands of lactation and lamb rearing. </SPAN></P><P><SPAN>BighornSummerRange [BSSR] is an ESRI SDE Feature Class showing Summer Range for Bighorn Sheep in Colorado. Summer Range is defined as that portion of the overall range where 90% of the individuals are located between spring green-up and the first heavy snowfall. Summer range is not exclusive of winter range; in some areas winter and summer ranges may overlap. </SPAN></P><P><SPAN>BighornWinterConcentration [BSWCA] is an ESRI SDE Feature Class showing that part of the winter range where animal densities are at least 200% greater than the surrounding winter range density during the same period used to define the winter range, in the average five winters out of ten. </SPAN></P><P><SPAN>BighornWinterRange [BSSR] is an ESRI SDE Feature Class showing that part of the overall range where 90% of the individuals are located during the average five winters out of ten, from the first heavy snowfall to spring green-up, or as a specific period which may defined for each unit. </SPAN></P><P><SPAN>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).</SPAN></P></DIV></DIV></DIV> |

Care should be taken in interpreting these data. Written documents may accompany this map and should be referenced. The information portrayed on these maps should not replace field studies necessary for more localized planning efforts. The data are gathered at a variety of scales; discrepancies may become apparent at larger scales. The areas portrayed here are graphic representations of phenomena that are difficult to reduce to two dimensions. Animal distributions are fluid; animal populations and their habitats are dynamic.</SPAN></P></DIV></DIV></DIV> |
