INVASIVE SPECIES INVENTORY AND MANAGEMENT
Post-fire Monitoring and Rehabilitation. Following wildfires at Ash Meadows National Wildlife Refuge over the last decade, RAs have mapped invasive weeds in the area and worked with U.S. Fish & Wildlife, National Park Service and U.S. Geological Survey staff to set up monitoring sites, and test experimental weed-treatment and native-planting methods. These projects have helped refuge managers establish effective fire-response strategies and provide proper funding levels for subsequent stages of the Ash Fire rehabilitation process.
Aquatic Invasive Species Eradication and Monitoring. Ash Meadows NWR is home to three federally-listed endangered endemic fish species as well as several endemic aquatic invertebrate species, which are threatened by the presence of at least ten known exotic aquatic species. RAs at Ash Meadows support efforts to eradicate black bullheads (Ameiurus melas), largemouth bass (Micropterus salmoides), green sunfish (Lepomis cyanellus), red swamp crayfish (Procambarus clarki) and mosquitofish (Gambusia affinis) in order to help endangered and endemic aquatic species reclaim their native habitat.
Weed Control. In partnership with the US Forest Service, GBI RAs help implement Nevada’s statewide weed management program. Noxious weeds and other invasive species continue to be among the biggest environmental dangers facing the state. RAs work throughout the state to inventory, map and treat noxious weed populations on both wilderness and non-wilderness lands. The GIS map databases created and maintained by RAs serve as the guiding management tool to direct and monitoring weed-eradication efforts now and into the future.
