Species Description: The Preble's meadow jumping mouse (Zapus hudsonius preblei) (Preble's or PMJM) is a small mammal approximately 9-inches in length with large hind feet adapted for jumping, along bicolored tail (which accounts for 60% of its length), and a distinct dark stripe down the middle of its back and is bordered on either side by gray to orange-brown fur. Location: This shy, largely nocturnal mouse lives primarily in heavily vegetated, shrub-dominated riparian (streamside) habitats and immediately adjacent upland habitats along the foothills of southeastern Wyoming south to Colorado Springs along the eastern edge of the Front Range of Colorado. The PMJM recently documented distribution includes Adams, Arapahoe, Boulder, Denver, Douglas, El Paso, Elbert, Jefferson, Larimer, and Weld counties in Colorado; and Albany, Laramie, Platte Goshen, and Converse counties in Wyoming. The Colorado portion of this area has undergone rapid residential, commercial, and industrial development that has impacted the PMJM habitat. Recent Actions: Learn about new proposed Critical Habitat On July 10, 2008, the Service removed Endangered Species Act protections for Preble's meadow jumping mouse populations in Wyoming and amended the listing for Preble's to indicate the subspecies remains protected as a threatened species in the Colorado portion of its range. The Service has determined the best commercial and scientific information available demonstrates that the Preble's meadow jumping mouse is a valid subspecies and should not be removed from the list of threatened and endangered species based on taxonomic revsion. For more information please see the following:
Background: On May 13, 1998, the U.S. Fish and Wildlife Service (Service) designated the mouse as threatened in its entire range (63 FR 26517). On June 23, 2003, we designated critical habitat for Preble’s 68 FR 37275). On May 20, 2004, we made permanent a final section 4(d) special rule for the Preble’s that provides exemptions from section 9 take prohibitions for certain rodent control activities, ongoing agricultural activities, maintenance and replacement of existing landscaping, existing uses of water, certain noxious weed control and ditch maintenance activities (66 FR 28125, 67 FR 61531, 69 FR 29101). On February 2, 2005, we issued a 12-Month Finding on a petition to delist the Preble's and proposed to remove the mouse from the Federal list of threatened and endangered species (70 FR 5404). On February 17, 2006, the Service extended the rule-making process an additional six-months due to substaintal disagreement regarding the sufficiency or accuracy of the available data (71 FR 8556; 71 FR 16090). On November 1, 2007, the Service announced a revised proposal to remove the Preble's populations in Wyoming from the List of Threatened and Endangered Species; and proposing to amend the listing for Prble's to indicate the subspecies remains threatened in the Colorado portion of its range. Additionally, the best commercial and scientific information available demonstrates that the Preble's is a valid subspecies and should not be removed from the List of Threatened and Endangered Species based upon taxonomic revision.
Below are public comments and peer review plans:
Conservation Efforts: A recovery plan that will describe the population and habitat conditions, and protections needed to remove this species from the Federal list is being developed. Federal, State, and local governments have protected lands that will contribute to recovery and long-term survival of the Preble's meadow jumping mouse.
