Best Practices for Ditch and Watercourse Maintenance: Managing Invasive Plants

Effective maintenance of ditches and watercourses is crucial for preventing the spread of invasive plants, which can displace native species, reduce biodiversity, and cause ecological harm. This guide outlines best practices for managing invasive species during maintenance activities. Key topics include understanding the contractor's role, identifying priority invasive plants like Common Tansy and Brown Knapweed, and following guidance from environmental practices and the B.C. Weed Control Act. Engage with your local Regional Committee for assistance in invasive plant management.
