small mammal Tomahawk trap set in the forest
Small mammal carnivore research
The terrestrial food web dynamics research project focuses on how mammalian carnivores of the Pacific Northwest forest interact with other components of the ecosystem. Specifically, the project aims to understand the ecology of the western spotted skunk: what it eats, where it lives, and how it is impacted by disturbances. To do this, researchers radio-collar spotted skunks and follow their movements. The project focuses on the HJ Andrews Experimental Forest and the surrounding Willamette National Forest. This photo gallery highlights field work at the Andrews Forest in fall of 2017 and 2018.
