A better look at jumping mice
Preble's meadow jumping mouse conservation
Ecology, movement, and population parameters (U.S. Air Force Academy)
Since 1994 CNHP has worked with the Natural Resources Branch of the U.S. Air Force Academy and the U.S. Fish and Wildlife Service to conserve and manage the Preble's meadow jumping mouse (Zapus hudsonius preblei) populations on the Academy.
Efforts to understand habitat use and PMJM movement patterns began in 1997 with the use of radiotelemetry. In 1998 a mark-recapture study was initiated along Monument Creek, with the study design being refined in 2000. From 2003 - 2005 fat sampling was conducted to look at composition and quantity of fat stored prior to and after hibernation. In 2007 an occupancy modeling approach was attempted, but capture success was uncommonly low.
Conservation and Management at Warren Air Force Base, Cheyenne, WY
CNHP was asked to write a conservation plan that combined Warren AFB's desire to maintain base function and infrastructure with conservation of PMJM and Colorado butterfly plant.
Investigating overlap in distribution between Zapus hudsonius and Zapus princeps in Colorado
In collaboration with Mark Bakeman (formerly of Ensight Technical Services) and Carron Meaney (now of Walsh Environmental) CNHP trapped multiple drainages along the South Platte River to locate PMJM. What was found is that both western jumping mice and meadow jumping mice inhabit some tributaries.
Rangewide surveys for Preble's meadow jumping mouse in Colorado
CNHP has sampled much of PMJM distribution and helped to define the current range. In 1997 field crews located the southern known extent in Colorado Springs, and we have continued to sample extralimital areas in Pueblo County, Teller County, Fremont County, and Larimer County.
