Description: <DIV STYLE="text-align:Left;"><DIV><DIV>Southern Rockies Lynx Amendment (SRLA) https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb5199574.pdfThe Glossary for the SRLA Management Direction (Attachment 1-12) defines lynx habitat. “Lynx habitat occurs in mesic coniferous forest that experience cold, snowy winters and provide a prey base of snowshoe hare. In the southern Rocky Mountains, lynx habitat generally occurs between 8,000 and 12,000 feet in elevation. Primary vegetation consists of Engelmann spruce, subalpine fir, aspen-conifer mix and lodgepole pine on spruce-fir habitat types. On cool moist sites, Douglas-fir and aspen, when interspersed with subalpine forests, may also contribute to lynx habitat. Dry forest types (e.g., ponderosa pine, climax lodgepole pine) do not provide lynx habitat.” Primary Vegetation Spruce-fir cover type Seral lodgepole pine cover type on subalpine fir habitat types Note: In addition to the lodgepole pine cover type, other moist conifer cover types such as Douglas-fir, white fir or blue spruce that currently dominate subalpine fir habitat type sites, should also be included as primary vegetation. This situation is what differentiates these cover types from those situations listed below where they would be considered secondary vegetation.Aspen mix Note:Since this meeting was held, “aspen mix” is currently described as any aspen cover type with a > 5% spruce-fir tree component. Secondary Vegetation Pure aspen Note:Since this meeting was held, “pure aspen” is currently described as any aspen cover type with a < 5% conifer tree component. Moist Douglas-fir Note:This may also include other cool, moist conifer cover types that do not occur on subalpine fir habitat sites, such as white fir or blue spruce. Riparian willow Sagebrush 3) Buffer only secondary vegetation. Note:Buffering 300 meters in to secondary habitat from primary, based upon Miller snowshoe hare data and R2 biologists’ discussions (Ft Collins, 2008). This buffer distance was derived from a “nearest neighbor” distance analysis performed on snowshoe hare pellet data collected from Miller, 2005. 4) Mountain shrub and sagebrush Note: Mountain shrub was included as secondary habitat in the initial mapping on some Forests. Based on lynx habitat use data from the Colorado Division of Wildlife, it has subsequently been determined that mountain shrubland receives little use and should be excluded from secondary vegetation (Randy Ghormley, pers. comm. 11/26/07).</DIV></DIV></DIV>
