Project Type: Specific Cooperative Agreement

Start Date: Sep 14, 2011
End Date: Aug 31, 2016

Objective:
To assess the impact of Eurasian Watermilfoil introductions into streams in the Western US. Emphasis is to be placed on assessing the changes in insect fauna assocated with the displacement of native vegetation and its implications for the native foodweb. Additional specific consideration is to be given to assessing the introduction and impact of insect biolgoical control agents of Eurasian Watermilfoil in California and Alaska.

Approach:
A combination of field sampling, laboratory assessment and experimental studies will be used to measure and assess the changes found in Western US stream where Eurasian Watermilfoil has invaded. Qualitative and quantitative models will be developed to compare actual sites of invasion with areas through to be high at risk for potential invasion. Cold water springfed streams will be the primary focus of study as they best represent Alaskan waters where Eurasian Watermilfoil is rated to be the State's largest exotic weed threat.
