As part of an ongoing collaboration with Nina Ferrari, a PhD candidate at Oregon State University’s College of Forestry, these illustrations were created to accompany her research and forthcoming publications. Nina climbs Douglas fir trees to study how microclimates and vertical habitats influence bird distribution in old-growth forests.
