Amy manages the RCD’s Habitat Enhancement program, which works to ensure there are all the quality natural habitats needed to support our diverse local wildlife. This includes projects that restore ancestral fish migration access, improve in-stream habitat, enhance wetlands, restore uplands and grasslands for butterflies and pollinators, and more. Volunteering with her hometown conservation district in high school to monitor water quality in a local stream sparked her interest in watershed ecology and salmon. She went on to obtain a B.S. in Environmental Science & Resource Management from the University of Washington, with a focus in sustainable forest management, soils, and hydrology. Amy previously worked to restore salmon habitat in the Lake Washington-Cedar-Sammamish Watershed in the greater Seattle area and later ran a conservation and recreation nonprofit in San Francisco, connecting people to urban trails and nature while conserving important habitat for urban wildlife. One of her favorite things about working at the RCD is getting to be “boots on the ground” to make meaningful and lasting impact for the local community, wildlife, and environment.
