I am collaborating with the USDA Forest Service - Chugach National Forest on a variety of projects related to invasive Elodea canadensis on the Copper River Delta within the Cordova Ranger District. We have three ongoing projects: 1. Using stable isotopes to assess whole food web response to Elodea in ponds across the delta; 2. Exploring the effect stands of Elodea on water chemistry, invertebrates, and fish compared to stands of native vegetation; and 3. Assessing the impacts of an Elodea-selective herbicide treatment on water chemistry, invertebrate communities, and fish.
