In the United States, the inland rainforest regions are also classified as significant habitat types for western redcedar and western hemlock. [20] Because of their humid climate, the inland rainforest patches support the establishment of oceanic species that would typically be expected to grow in maritime and coastal environments.
The Appalachian temperate rainforest has a cool and mild climate and meets the criteria of temperate rainforests identified by Alaback. [1] Temperature and precipitation are extremely variable with elevation, with rainforest conditions usually but not always concentrated around spruce–fir forests at higher elevations.
A portion of the temperate rain forest region of North America, the largest area of temperate zone rainforests on the planet, is the Pacific temperate rain forests ecoregion, which occur on west-facing coastal mountains along the Pacific coast of North America, from Kodiak Island in Alaska to northern California, and are part of the Nearctic realm.

Map of wood-filled areas in the United States, circa 2000 [1]. In the United States, the forest cover by state and territory is estimated from tree-attributes using the basic statistics reported by the Forest Inventory and Analysis (FIA) program of the Forest Service. [2]
Archeologists have uncovered a cluster of lost cities in the Amazon rainforest that was home to at least 10,000 farmers around 2,000 years ago, according to a paper published Thursday, Jan. 11 ...
Beyond the northern end of Vancouver Island, is the "perhumid rain forest zone". Douglas fir wanes as a dominant species, and the forest is primarily made up of western red cedar, Sitka spruce, and western hemlock. The Gulf of Alaska begins where the fjords of southeast Alaska end, and marks the transition into "sub-polar rain forest". Here the ...
