Best Management Practices
Invasive species are plants and animals that have been introduced to an area without the predators and pathogens from their native habitats that would help keep them in check. They can threaten property and recreational values, infrastructure, agriculture, public health and safety, as well as the ecological health and diversity of our natural environment.
Technical Guides for Practitioners
Invasive species are often difficult to control. The Invasive Species Council of Metro Vancouver works with the Metro Vancouver Regional District and many experts across the region to develop locally tested and science-based best practices for practitioners (e.g., municipal staff, contractors, landscapers, developers, stewardship groups and others) to manage a growing list of invasive species. These species-specific guides provide the best local information on identification, tracking, management, disposal and restoration.
