COLORADO PARKS & WILDL I F E State of Colorado Aquatic Nuisance Species Management Plan Invasive Species Program cpw.state.co.us The Colorado Aquatic Nuisance Species Management Plan is part of a multi-jurisdictional collaborative efort to prevent and contain aquatic nuisance species to avoid or mitigate negative impacts to natural resources, outdoor recreation, and the water infrastructure of the state. Colorado Parks and Wildlife is providing coordination for the implementation of this plan, and together with their partners, are providing implementation guidance and oversight.
