Amie Loop-Frison

Habitat Conservationist

Amie has been with Yamhill Soil and Water Conservation District since 2004. Currently, Amy is working with landowners interested in prairie and oak habitat restoration. She has been working on developing a Habitat Conservation Plan (HCP) for Fender’s blue butterfly on privately owned lands within Yamhill County for the past four years. She assists landowners with a variety of wildlife issues including habitat enhancements as well as advising on native plant topics. Prior to working on the HCP, Amie spent six years as the Riparian Specialist with the District.

Amie received her Bachelors of Science in Wildlife Science from Oregon State University in 1995 and worked as a trainee for the Natural Resources Conservation Service before heading to southern Oregon to work as a biological technician for the Bureau of Land Management. This is where she began working with threatened and endangered wildlife species focusing on the northern spotted owl. She then worked for Willamette Industries, which eventually became Weyerhaeuser Corporation, as their Wildlife Coordinator for Oregon. She was responsible for coordinating surveys, inventorying and monitoring all company ownership for sensitive and rare wildlife species including spotted owls and marbled murrelets.

Keith Nasman
Keith Nasman

Conservation Technician

Yamhill SWCD would like to announce the appointment of Keith Nasman as Conservation Technician. Keith grew up in the exurbs of New York City amongst towering sugar maples and white pines. He spent much of his youth exploring the hills and forests and was encouraged by his high school biology teacher to take field biology. The class focused on doing an environmental survey of the little stream behind the school. This work resulted in the state upgrading the stream from a trout stream to a trout breeding stream, changing how future development would impact the area. This led Keith to pursue a biology degree at Lewis & Clark College. He settled in Portland and raised a family while working in many capacities at a scientific distribution company. With the kids grown up it was time to find a second, more meaningful career. Volunteering at Miller Woods led to an opportunity for the summer as Assistant Land Steward and now the Conservation Technician role. Outside of work, Keith is an avid sailor and boatbuilder.
