Habitat: This salamander is found under bark or moss in mature and second-growth Douglas-fir forests, as well as under rocks or logs in stands of moist hardwood forests within coniferous forest landscapes. Usually it is absent from recent clear-cuts, but it is sometimes found in talus and lava fields near the crest of the Cascades. Reproduction: A clutch of 6 eggs (range 3-11) is laid in the spring and hatches after about 4 months. Eggs are guarded by the female. Food Habits: As is typical of small salamanders, the Oregon slender salamander eats small invertebrates like springtails, mites, insect larvae and adults, spiders, snails, and earthworms.

Next, a habitat map, based on vegetation cover types and the species that occupy them, is created. Then each species is assigned to a set of habitat types. The final map represents all habitat types associated with a particular species within its distributional limits in Oregon. Cartography is the art and science of making maps. On maps, the real world is represented at reduced scale by lines, symbols, shadings, and other graphic conventions. Maps are only a representation of reality and cannot depict all the detail one encounters in nature.
