Component 4
Monitoring


Objective: Identify the presence or absence of zebra mussels and other ANS in the 100th meridian jurisdictions and west.

Although currently undetected, it is possible exists that zebra mussels may have already spread west of the 100th meridian. Monitoring is an important component of this Initiative to ensure that if zebra mussels are present, they will be detected. Early warning of zebra mussel infestation can decrease their potential impact on native resources, manmade structures, and the economy. This component will expand upon current management activities of Federal water management agencies, the U.S. Fish and Wildlife Service (Service), States, electric utilities, and others. Monitoring protocol will be developed through a workshop represented by Federal, State, and private entities. The Service will coordinate efforts to monitor for the presence or absence of zebra mussels. Findings will be reported to the National Nonindigenous Aquatic Nuisance Species Information Center in Gainesville, Florida.

Assessments of water bodies in 100th meridian jurisdictions and west will be conducted by Federal and State agencies to determine their risk for zebra mussel infestation. Physical and chemical measurements will be evaluated using a standardized risk assessment protocol along with recreational use. Maps of assessed sites will be available to State resource agencies. High- risk waters will be monitored periodically.

High-risk areas include water bodies 1) that have conditions to sustain zebra mussels, 2) where boating, personal watercraft, and angling activities originated from infested waters, and 3) are in less than a 3 day drive from waters with zebra mussels.

Moderate-risk areas include water bodies 1) that have appropriate water conditions to sustain zebra mussels, 2) where boating, personal watercraft, and angling activities originated from infested areas, and 3) are not in close proximity to infested areas.

Low-risk areas include water bodies that 1) do not have appropriate water conditions to sustain zebra mussels, 2) do not have boating, personal watercraft, and angling activities, and 3) are not in close proximity to infested areas (Assessment and Identification of Western Waters at Risk for Infestation of Zebra Mussels by Boating and angling Activities).
