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.”

Aquatic Invasive Species

The Pacific Southwest Region Aquatic Invasive Species Program provides general invasive species materials and information at festivals, fishing derbies, boating shows, sportsmen shows, and other events. The program also provides outreach materials involving invasive plants and animals.

What is an Invasive Species

Invasive species are plant or animal species that are:

  • not native to an ecosystem
  • are capable of becoming established
  • once establish can cause economic or environmental harm or harm to human health

What is an Aquatic Invasive Species

An invasive species that lives at least part of its life in an aquatic environment.

Species of Concern

Hazard Analysis and Critical Control Point (HACCP)

Planning Is EverythingHazard Analysis and Critical Control Point planning for natural resource management is a five step tool to reduce the risk of spreading invasive species and other non-targets (non-target = anything that you do not want to move from one place to another) in human related pathways (pathway = An activity or process through which a species may be transferred to a new location where it could become introduced). This tool defines the critical point in a given activity whereby the risk of a hazard (hazard = non-target or invasive species movement) can be reduced to an acceptable level. At this critical control point, the risk of a hazard is reduced by means of a control measure. This control measure is then evaluated to ensure that the control measure is operating as intended.

As part of campaigns to help prevent the spread of invasive by increasing awareness, HACCP has become a recognizable brand. HACCP training workshops, a website, and an international standard have been created.

The 100th Meridian Initiative

100th Meridian Initiative logo

The 100th Meridian Initiative is a cooperative effort between local, state, provincial, regional and federal agencies to prevent the westward spread of zebra/quagga mussels and other aquatic nuisance species in North America. The lastest version of the Zap the Zebra brochure can be found at the 100th Meridan website.

Stop Aquatic Hitchikers

The Stop Aquatic Hitchhikers

The Stop Aquatic Hitchhikers campaign empowers recreational users to become part of the solution in stopping the transport and spread of these harmful hitchhikers.


Habitattitude is about consumer awareness and responsible behaviors. By drawing attention to the potential environmental ramifications of the aquarium and water garden hobbies while promoting responsible consumer behaviors. The Habitatitude campaign avoids the definition debate surrounding "invasive species". Ultimately, the campaign seeks to eliminate the transfer and survival of any species outside of your enclosed, artificial system, which has the potential to cause the loss or decline of native plants and animals.
