Red tree vole Red tree vole The red tree vole ("Arborimus longicaudus") is a rodent found in Oregon and California. The red tree vole is a rodent in the family Cricetidae. It is found only in coastal forests of Oregon and northern California. They eat exclusively the needles of conifers, mostly Douglas-fir ("Pseudotsuga menziesii") and occasionally other species. They often spend their lives in just one tree, and many generations will live in different parts of the same tree. When eating Douglas-fir needles, they carefully remove the fine resin ducts (which resemble coarse, straight hairs) along each edge of the needle, discarding these
Douglas Ranges flows along the southeast flank of the range. East of the Douglas Ranges, across Harrison Lake, are the Lillooet Ranges, while to the west and northwest are the Garibaldi Ranges. Southeast across the Fraser River is the Canadian portion of the Cascade Range. Because of the warmer climate (relative to the rest, even, of the British Columbia coastal lowlands), there were forests of immense trees throughout the Douglas Ranges, which were logged relatively early on in British Columbia's history. A network of logging railroads ran throughout the basin of the Chehalis River, which drains the core of the ranges to
