BLM OR SEORMP Wildlife Disturbance Roads Polygon

wld_Disturbance_Cap_Roads_110415: Greater Sage-grouse researchers observed relative impacts of different transportation assets to the Greater Sage-grouse. The direct area of influence for roads will be represented by 240.2 feet, 84.0 feet, and 40.7 feet total widths centered on the liner feature for Interstate Highways, Major Roads, and Minor Roads, respectively (Knick et al. 2011). In Knick et al. 2011, major roads are equivalent to federal and state highways and minor roads are equivalent to secondary roads. (Knick, S.T., S.E. Hanser, R.F. Miller, D.A. Pyke, M.J. Wisdom, S.P. Finn, E.T. Rinkes, and C.J. Henny. 2011. Ecological influence and pathways of land use in sagebrush. Pages 203-251 in S.T. Knick and J.W. Connelly (editors). Greater Sage-Grouse: ecology and conservation of a landscape species and its habitats. Studies in Avian Biology (vol. 38). University of California Press, Berkeley, CA).

This purpose of this field is to identify the minor roads in Greater Sage-grouse Priority Habitat Management Areas within the Resource Area Boundary of the SEORMP, which count toward the 3% anthropogenic disturbance. There is a relationship documented in scientific literature between the amount of use a road receives and its impacts on sage-grouse. Since traffic volume is not known for most roads in eastern Oregon, maintenance level serves as a surrogate for the amount and seasonality of road use. Inventoried roads with a maintenance level 3, 4, or 5 are minor roads under this definition.

Interstate highways and major roads are identified in the highways feature class. Interstate highways, major roads, and minor roads will be buffered and then clipped to the Greater Sage-grouse Priority Habitat Management Areas prior to being published to a roads disturbance cap feature class.
