Modeling Region 7 : Klamath Mountains -- Oregon

MR 7 MR 1MR 2MR 3MR 4MR 5MR 6MR 7MR 8MR 9


The Klamath Mountains ecoregion is physically and biologically diverse. Highly dissected, folded mountains, foothills, terraces, and floodplains occur and are underlain by igneous, sedimentary, and some metamorphic rock. The mild, subhumid climate of the Klamath Mountains is characterized by a lengthy summer drought. It supports a mix of northern Californian and Pacific Northwest tree species.
