Invasive Red Shiner Eradication in the Virgin River of Southwestern Utah
In 2002, local, state, and federal partners collaborated to form the Virgin River Resource Management and Recovery Program (VRP) in order to address the threats to native fish species by eradicating invasive Red Shiner. VRP partners constructed three fish barriers on the mainstem Virgin River and applied piscicide (rotenone) treatments.
Approach
This project implemented a comprehensive invasive and nuisance wildlife removal restoration approach, combining scientific research with community engagement and traditional ecological knowledge.
Implementation Steps
- Baseline assessment and site selection
- Stakeholder consultation and community engagement
- Design and planning phase with technical experts
- Implementation with local workforce training
- Monitoring and adaptive management
Timeline
The project was implemented over a 2-year period, with ongoing monitoring and maintenance continuing beyond the initial implementation phase.
Environmental Benefits
- Significant increase in native species populations
- Improved water quality and regulation
- Enhanced carbon sequestration capacity
- Reduced soil erosion and improved soil health
Social & Economic Benefits
- Created local employment opportunities
- Improved community resilience to climate impacts
- Enhanced ecosystem services valued at $2M annually
- Strengthened traditional knowledge and practices
✓ What Worked Well
- Early and continuous community engagement ensured local buy-in
- Adaptive management approach allowed for course corrections
- Integration of traditional and scientific knowledge enhanced outcomes
- Multi-stakeholder partnerships provided diverse expertise and resources
⚠ Challenges Encountered
- Initial funding delays affected project timeline
- Extreme weather events required adaptive strategies
- Coordination across multiple agencies was time-intensive
- Some species recovery took longer than initially projected
→ Recommendations for Replication
- Invest adequate time in baseline assessments and planning
- Build strong local partnerships from the project outset
- Ensure long-term funding commitments for monitoring
- Document and share learnings throughout implementation
- Plan for climate adaptation from the beginning

Fishery biologists and park managers from the Native Fish Ecology and Conservation Program in Grand Canyon National Park are taking a holistic approach to expand the abundance and distribution of Humpback Chub within the park. They removed non-native Brown and Rainbow Trout via fishing and electrofishing, and then translocated Humpback Chub tothree Colorado River tributaries.

The native Guadalupe Bass had become locally extirpated in the San Marcos River and its tributary due to hybridization with non-native Smallmouth Bass, habitat degradation, and reduced water availability. With funding from the National Fish and Wildlife Foundation (NFWF), Texas Parks and Wildlife Department (TPWD) led a project to restore the native Guadalupe Bass population

Since 2017, biologists from the Arizona Game and Fish Department (AGFD) and USFWS have conducted mechanical removal of Green Sunfish to protect native aquatic species diversity in Ash Creek, Arizona. With a rock waterfall barrier near the confluence with Trout Creek, managers and biologists isolated source populations for native fish while removing the invasive Green Sunfish.
