Spotlights

Wyoming Game & Fish Department.

Anglers, crayfish trappers, and other outdoor recreationists are asked to help the Wyoming Game and Fish Department protect our outstanding fisheries by reporting any rusty crayfish found in the Laramie River watershed. Rusty crayfish (Orconectes rusticus) are native to the Ohio River Basin, but have invaded many other states and Canadian provinces. They were first discovered in Wyoming in 2006 after being illegally introduced into private ponds and then escaping into Wagonhound Creek, a tributary of the North Platte River. Despite the Game and Fish Department’s early eradication efforts, the species has recently been found in the Laramie River as a result of another illegal introduction.

Rusty crayfish are 3-5 inches long, with a grayish-green body and easily-identifiable reddish fingerprint-like spots on each side of the body just in front of the tail. If you find a rusty crayfish, or catch one in a trap, take a photo of it and either return it to the water or kill it. Then contact the Laramie Game and Fish Department at (307) 745-4046 or reportais@wyo.gov.

Wildlife researchers have confirmed the presence of white-nose syndrome (WNS) in bats at Devils Tower National Monument. While this is the first confirmation of WNS in the state, the fungus that causes WNS, Pseudogymnoascus destructans (Pd), was potentially detected in southeast Wyoming as early as 2018. Biologists from the University of Wyoming discovered evidence of WNS during surveys completed in early May 2021, when they captured and sampled bats to test for the fungus.

The NPS will be working closely with the climbing community at Devils Tower to better understand and develop guidance for climbers to help care for and protect Wyoming’s bat populations – including how to safely clean and disinfect climbing gear. Climbers and cavers who have used gear or clothing in WNS-infected areas should not re-use them in areas not already known to have Pd fungus. If you see a sick or dead bat, report it to park rangers or Game and Fish biologists, but do not touch or pick up the bat.

Wyoming Game and Fish Department.

For more than a decade the Wyoming Game and Fish Department has prioritized keeping aquatic invasive species (AIS) out of the state’s lakes and reservoirs. But, as the threat of zebra and quagga mussels grow, Game and Fish is taking extra precautions to prepare. This spring, the department is rolling out rapid response plans to help act quickly if AIS are discovered, and wants feedback from the public. Game and Fish is taking public comments until May 16, 2021 on 22 proposed plans for lakes and reservoirs throughout the state.

State of Wyoming.

Governor Mark Gordon’s Invasive Species Initiative delivered a series of recommendations in its final report that could help Wyoming be a national leader on combating invasive species. The roughly forty-page report addresses a wide array of topics surrounding terrestrial invasive plant species and includes recommendations for the Governor to consider in the coming years. They include developing assessments, improving collaboration with federal partners, and exploring revisions to the funding model for invasive species management in the state.

Please check this information before you transport your watercraft into Wyoming as this information will be updated regularly. This site includes detailed information and a map of inspection facilities including locations, dates of operation, and hours of operation. Any watercraft transported into Wyoming from March 1 through November 30 must undergo a mandatory inspection by an authorized inspector prior to launching in any water of the state.

The Wyoming Weed Watchlist Field Guide is designed to enhance prevention and early detection efforts of weeds not yet widely established in Wyoming. It was developed by students enrolled in the University of Wyoming's Invasive Plant Ecology course of fall semester 2010. The field guide is not intended as a management handbook, but rather an educational tool for outdoor recreationalists, natural resource professionals, tourists, gardeners, agriculturalists, and others to aid in identification of unfamiliar, yet extremely important, weeds in the region. The highest leverage step in reducing potential impact of new invasive weeds in Wyoming is to detect new populations before they can become well established.
