  • The Nature Conservancy, University of Wyoming and Wyoming Game and Fish Department released a new study identifying Wyoming species like the pygmy rabbit as most vulnerable to future population declines.
  • Birds, such as the burrowing owl, were determined to be the most vulnerable to disease. Other risk factors studied in the report include residential and energy development, and climate changes.
  • The most vulnerable taxonomic group overall were reptiles, with nearly half the species evaluated ranked as highly vulnerable to one or more of the identified risk factors.
  • The study acts as an early warning to alert state leaders where to invest conservation efforts before sensitive species like the plains spadefoot face serious population declines.
  • The study’s list of 51 highly vulnerable species also includes the greater sage-grouse, which has sparked unprecedented efforts in Wyoming to protect the grouse and avoid an ESA listing.
  • Amphibians such as the Wyoming toad were rated most vulnerable to climate change, according to the study.
