Preble’s Meadow Jumping Mouse to Remain Protected


On April 16, 2018, the U.S. Fish and Wildlife Service decided that the Preble’s meadow jumping mouse (Zapus hudsonius preblei) will remain protected under the Endangered Species Act. The mouse was listed as threatened in 1998.

The decision by USFWS is good news for the WES Rocky Mountain Regional office, which has recently proposed the Big Thompson Confluence Mitigation Bank in Weld County Colorado. This Bank will offer Preble’s credits to offset impacts from projects such as transportation, home construction, and water development.

Typical Preble’s meadow jumping mouse habitat consists of areas near open water with dense, herbaceous riparian vegetation and an overstory canopy layer as well as upland grassland areas adjacent to riparian habitat (USFWS 2016). These are precisely the habitat types the Big Thompson Confluence Mitigation Bank is seeking to restore through the re-connection of the Big Thompson River to its historic floodplain. Major threats to this mouse include the loss of riparian habitats and other factors associated with urbanization (USFWS 2016).
