Laramie, WY – A Laramie-based environmental group contends the Preble's Meadow Jumping Mouse needs continued Endangered Species Act protections. Jeff Kessler of Biodiversity Conservation Alliance also disputes a study cited by the State of Wyoming as evidence why the mouse should be de-listed. Kessler says the Denver Museum of Nature and Science study had a number of problems. He says scientists reviewing the work questioned the study's scientific methods and unsupported conclusions made by the author. Kessler says the evidence suggests the Bear Lodge Meadow Jumping Mouse in the Black Hills deserves to be listed as well. He says the habitats for both mire are in poor condition and are disappearing due to development.
