NORTHERN SPOTTED OWL (Strix occidentalis) STATUS: THREATENED

The Northern Spotted Owl is dependent on old growth Douglas Fir and Redwood trees for nesting and finding food. They need to roost in old-growth forests because these habitats offer cool, damp conditions, with plenty of holes and cavities to roost in. Studies have found that adult survival has declined in recent years because of unsustainable logging and clear cutting practices. Their numbers have further dwindled because their main food source, the Red Tree Vole, is also declining in numbers.

 

MARBLED MURRELET (Brachyramphus marmoratus)
STATUS: THREATENED

The threatened marbled murrelet is a small seabird which flies inland to nest on the mossy limbs of old-growth trees. During the past century California's murrelet population dropped from 60,000 to approximately 4,000 individuals. Pacific Lumber's ancient redwood groves in Humboldt County are one of three remaining nesting areas in California. The murrelet's dependence on old-growth nesting habitat and use of coastal marine feeding areas have brought it into frequent conflict with human economic interests.
   
CALIFORNIA RED TREE VOLE (Arborimus pomo)
STATUS: ENDANGERED
Red Tree Voles are found along the Pacific coastal lowlands in Oregon and Northern California. Red Tree Voles live only in coastal coniferous forests consisting of Douglas Fir, Grand Fir, Western Hemlock, and/or Sitka Spruce. They live, nest, and feed within the forest canopy. Their reproductive potential is lower than typical voles. This coupled with the fact that their home range has been extensively logged has jeopardized their survival. Clear-cutting has significantly reduced available habitat and fragmented populations. One reason the Northern Spotted Owl is endangered is because the Red Tree Vole population, on which it feed, has shrunk dramatically.
   

CHINOOK SALMON (Oncorhynchus tshawytscha)
CHUM SALMON (Oncorhynchus keta)
COHO SALMON (Oncorhynchus kisutch)
STEELHEAD TROUT (Oncorhynchus mykiss)

STATUS: ENDANGERED
STATUS: ENDANGERED
STATUS: ENDANGERED
STATUS: THREATENED

The many Salmon on the U.S. Endangered Species List. Certain naturally spawned populations in California and Oregon are classified as threatened. In California the population of Coho Salmon has dropped from half a million in the 1940s to a few thousand today. The biggest impact has been dealt by the logging industry. Cutting of trees exposes the salmon's spawning streams to sunlight, which heats the water to temperatures that are lethal to these fish. Additionally, erosion from logging activities causes the steams to silt up and become too muddy for the fish and their eggs to survive in. The logging industry opposes measures that would help conserve salmon habitats and restore populations.
