Lower Colorado River Multi-Species Conservation Program Rodent Monitoring Summary Data
Summary data for Lower Colorado River Multi-Species Conservation Program (LCR MSCP) rodent monitoring at conservation areas, as polygons with point representation. Each polygon represents a trapping effort with number of each species captured during that trapping effort (minimum convex polygon of trapping locations at a given transect/date). Within the LCR MSCP habitat creation goals, 125 acres of habitat are to be created for the Colorado River cotton rat, and 76 acres are to be created for the Yuma hispid cotton rat. It is currently believed that the ranges of these two cotton rat species do not overlap. Those captured south of the Trigo and Chocolate Mountains in the area of the Imperial National Wildlife Refuge and south of the Yuma, Arizona, area to date are Yuma hispid cotton rats. Those captured north of the aforementioned mountain ranges to date are Colorado River cotton rats. The northernmost historic records of Colorado River cotton rats are from an area just south of Laughlin, Nevada (Bradley 1966; Hall 1946). Colorado River cotton rats were captured in 2012 at the Big Bend Conservation Area, marking the first record of the species in Nevada since 1966. Desert pocket mice occur in creosote bush (Larrea tridentata) and xeric riparian communities of the Southwest, from Baja California, Mexico in the South and southeastern California, southern Nevada, and extreme southwestern Utah in the North. The range of the sobrinus subspecies is not well documented, but it is believed to be within Clark County, Nevada, and may be present farther south. The desert pocket mice caught during rodent surveys are not evaluated to determine whether or not they were of the sobrinus subspecies. Each polygon is the minimum convex polygon of trapping locations at a given transect/date). Attributes of polygon include number of each species trapped per trapping effort.
