Project Name
Cottonwood Habitat Overstory Management Program
Overview
This project is a joint initiative between the Flood Mitigation Department, City of Merritt, and the Lower Nicola Band Aquatics Department.
Together, we are working to protect old-growth cottonwood trees along the Coldwater and Nicola Rivers by implementing humane and non-destructive measures to deter beaver activity.
Beginning Thursday, May 22, LNIB crews will begin wrapping select old-growth cottonwoods using humane, non-lethal materials that discourage beaver activity without harming wildlife.
This important work will continue over the next four weeks, with a focus on long-term habitat preservation that balances both ecological and cultural values.
To learn more about the program and see how this work connects to broader flood mitigation efforts, You can speak with the team in person at the City of Merritt Open House on May 28 4:00pm-8:00pm at the Civic Centre, we’d love to see you there!
Why It Matters
These mature cottonwoods are essential to the health of the river ecosystems.
They contribute by:
- Providing Shade: Helping regulate water temperature for fish species.
- Stabilizing Riverbanks: Preventing erosion and supporting long-term ecosystem stability.
Key Benefits
- Protection of critical riparian habitat without harming local beaver populations.
- Improved river health for aquatic species in the Coldwater and Nicola systems.
- Increased community engagement and stewardship of local natural resources.
Scope of Work
- Survey and map existing old-growth cottonwoods along the rivers.
- Apply proven, non-lethal deterrents (e.g., tree wrapping) to protect trees.
- Work with Rightsholders, community partners, and residents to share knowledge and build support.
Methods & Considerations
While various tree-wrapping techniques exist, the City of Merritt has opted not to use textural repellents like sand paint, due to potential risks to beavers and other wildlife. The goal is to balance habitat preservation with ecological responsibility.
