Biological Diversity

The fifty three species of mammals recorded at the Andrews Forest include black bear, flying squirrel, deer, and red tree voles. To learn more about what animals live at the forest, see our Species List page.

Twenty different species of reptiles (which include lizards) and amphibians (which include salamanders) can be found at the Andrews Forest. The rough-skinned newt (Taricha granulosa) is so commonplace at the Forest that it has taken on the role of mascot, appearing in the Andrews Forest logo.  The Pacific Giant Salamander (Dicamptodon ensatus), fondly nicknamed Dicamp by researchers, can reach up to 12 inches (30 cm) long.

The nine species of fish found at the Andrews Forest live in the small, cold streams that flow through the forest. The species include the cutthroat trout, the mottled sculpin, and the speckled dace. To learn more about the kinds of fish and other creatures at the Andrews Forest, see our Species Lists page.

Plant species at the Andrews Forest include enormous Douglas fir trees, which can reach 300 feet tall, and the tiniest mosses. The 505 species recorded include plants with flowers, cones, catkins, and fruits. The full list of plants species can be found on our Species Lists page. 

The Andrews Forest is home to resident birds, such as the Varied Thrush and the the iconic Northern Spotted Owl, which stay all year round. The Forest is also home to migratory birds, such as the Black-Throated Grey Warbler and the Swainson's Thrush, which spend the summer breeding season at the Andrews Forest and fly south for the summer.
