What is the current distribution of aquatic invasive species in the watershed?

Aquatic invasive species pose an ever-increasing threat to the health of aquatic ecosystems worldwide.  Non-native species threaten the diversity of native species through competition for habitat space and resources, predation, disease transmission, habitat alterations, and water quality impairments.  Invasive species can also directly impact human activities by clogging navigable waterways and water delivery systems, weakening flood control structures, or diminishing sport-fish populations.  Humans can also act as vectors for spreading invasive species so people need to be especially aware of traveling from natural areas, farms, or waterways for work or recreation and the risk of spreading invasive species on their vehicles, boats, equipment and clothing. 


So how do you control aquatic invasive species?  Early detection and rapid response have been found to be the most effective and cost efficient ways to control invasive species other than preventing them in the first place.  Launched in 2011, SYRCL began the Yuba Watershed Sensitive and Invasive Species watch program in order to track the distribution of invasive species as well as sensitive species of concern throughout the watershed.  This project is still in its preliminary stages and will continue to expand beyond just SYRCL river monitoring sites.  To view the field guide click hereThe map below shows some occurrences monitors have reported thus far.

California Aquatic Invasive Species Management Plan.  

This management plan developed by the Department of Fish and Game proposes management actions for addressing aquatic invasive species (AIS) threats to the State of California.  It primarily focuses on invasive algae, crabs, clams, fish, plants and other species that continue to invade California’s creeks, wetlands, rivers, bays and coastal waters. 

California's Surface Water Ambient Monitoring Program Aquatic Invasive Species: Issues Concerning Water Quality Monitors

This webinar created by the State Water Resources Control Board: Clean Water Team gives an overview of Aquatic Invasive Species (AIS), the harm they can cause, tips for prevention and highlights some non-native species of concern.  

California Invasive Species List 

The Invasive Species Council of California created this website in order to keep an inventory of invasive species that threaten the state.  The site not only contains a species list but also scorecards for each species that evaluate their potential impact, if spread, and their potential response to  eradication treatments.
