CNPS is working to preserve California’s native plants and their habitats. Achieving that mission sometimes requires that we provide clear, science-based rationale for our conservation actions. CNPS Conservation Policies provide the reasoning for positions we take on specific conservation issues. Using a consistent program policy development process, conservation policy topics are selected, developed, and approved by the CNPS Chapter Council.
