Aquatic Invasive Species

Aquatic Invasive Species provides leadership in preventing, managing, and mitigating the impacts of invasive species on ecosystem health.

Our long-term goal is to protect and restore healthy ecosystems in the states of California and Nevada by being accountable for providing decision support and guidance to our partners.

Resource management work often creates open pathways that could spread invasive species to unique and critical habitats for already endangered species. Next to habitat loss, invasive species are resource management's biggest challenge.

Executive Order 13112, 1999 , directs agencies to prevent the spread of invasive species in their work but few management tools exist to implement this Directive. Hazard Analysis and Critical Control Points (HACCP) planning has been modified from the food industry for natural resource work.

Around the world industry uses the HACCP planning tool to remove product contamination. In natural resource pathways, hitchhiking species are considered contaminants. HACCP's comprehensive planning identifies these species and the risk of contamination while documenting the best management practices used to prevent and remove hitchhikers.
