The Forest Inventory and Analysis (FIA) program reports on the status and trends of Washington’s forest resources, producing comprehensive updates every 5 years. This report provides detailed estimates of forest area, tree species composition and distribution, volume, biomass, carbon, standing dead trees and down wood, and understory vegetation on forest land for the state of Washington. It also includes estimates of annual growth, mortality, and removals on forest land. Estimates are based on inventory data collected on 6,112 forested FIA plots in Washington between 2007 and 2016. There are 22.5 million forested acres in Washington covering about half the state’s land area. Washington has 9.4 billion live trees on forest land that collectively represent 94.3 billion ft3 of net volume or 853.3 million Mg of carbon. The majority of this forest volume occurs on the moist west side of the state. Net change in volume on forest land was positive for all ownership groups in western Washington, but negative on National Forest System lands in eastern Washington, especially in wilderness areas. Statewide, net change in volume was 20 ft3 ac-1 yr-1 or a total addition to net volume of 415 million ft3 yr-1.

Tree Species – Washington Forest Protection Association

The forests of the Pacific Northwest contain more evergreens than almost anywhere in the United States. Evergreen trees are special because they do not lose their needles during the fall. Washington’s forests are home to about 25 native tree species. All plants grow best when they live in the environment they are most suited for – cactus in the desert, grasses in the plains – tall, green firs and cedars prefer our cool, wet winters and moderate summers. When foresters practice sustainable forestry, many different types of trees grow throughout the four main forest regions during the sustainable forestry life cycle. Below are a few of the more popular tree species that you’ll find in our forests.

Tree of Choice



It grows so well in all of our forest regions, and because its wood is prized worldwide for its strength and durability, Douglas-fir is often the tree of choice for many Washington forest landowners. The tree’s intolerance of shade means Douglas-fir grows best in open sunlight. That’s why it does so well in land cleared by harvesting, wildfire, or even volcanic eruption.​

90,000 trees in Washington - trees







Washington's nickname - "Evergreated state", therefore it is not surprising that at least 32 species of trees live in the state, in the state. most of which are evergreen. In addition to evergreen trees, Washington has several deciduous trees and the Pacific yew, whose bark and needles are used to make cancer drugs.

Washington Pines include beach, lodge, bark white, western white, and ponderosa. Western white pine, lodge and ponderosa are valuable for finishing joinery and paper pulp. Shore pines and white bark serve to protect streams and prevent erosion.

Washington fir species include noble, pacific silver, alpine and subalpine, great and douglas silver. Some, especially Douglas and noble firs, are common Christmas trees, while others are mostly valuable for lumber and pulp. Many species often succumb to internal decay with age.

Washington larch trees, subalpine larch and western larch, are part of the only group of conifers, or cone-bearing trees, that shed their leaves in winter. Although valuable as an erosion control, subalpine larch is not used by loggers because it grows high in the mountains and is quite short. Western larch, however, can be made into house frames, telephone poles, or rail ties, among other things.

Spruce and Bumps

Washington spruce includes Engelmann spruce and Sitka spruce. Engelmann spruce can be used for lumber and pulp production, but is not particularly popular. Sitka spruce is widely used in musical instruments, and its light and strong wood makes beautiful staircases.

Washington swamp trees, western bologoth, and mountain bologoth differ considerably. The mountain boligul is more of a shrub than a tree and grows so high in the Washington Cascade and the Olympic Mountains that it is not worth the effort to collect. The tall western hemlock, on the other hand, is the state tree of Washington and is very important for both lumber and paper pulp.

Cedar and Juniper

Washington cedar and juniper includes western red cedar, Alaska cedar and Rocky Mountain juniper. Western red cedar forest makes up nearly all wood shingle and trembling in the United States. Western red cedar and Rocky Mountain juniper are also used to make fences. Alaska cedar grows primarily in mountainous areas, and its wood is useful for boat building and fine carpentry.

Yew trees

Pacific yew, the only yew in Washington, often grows in the shade of other trees and never grows very tall. Its needles and bark secrete small amounts of paclitaxel, a powerful anti-cancer compound. While a similar chemical can now be partly synthesized in a lab, Pacific yew remains an important part of the fight against cancer.

Willow, Aspen and Poplar Trees

Washington has 12 willows, 1 aspen and 1 cotton. Only black cotton is commercially valuable and useful as paper pulp, firewood, and plywood plywood. Willows and trembling aspen are primarily useful for protecting soil and streams.

Birch, Alder & Oak

There are only a few birches in Washington DC that are used for furniture when possible. The only variety of oak in Washington, the Oregon white oak, grows in rocky areas and is mainly used as firewood for individual houses. According to Washington State University, red alder is "the state's most important timber." It grows quickly and can be used for lumber, paper pulp and furniture.

Maple and Dogwood

Washington has two types of maple: vine maple and bigleaf maple. The vine maple makes excellent firewood and provides food for animals, but is otherwise unpleasant, as it tends to form dense thickets. Bigleaf maple produces good firewood and is used in furniture production. Many cities also use maples as shade trees.

The only dogwood in Washington, Pacific dogwood, mostly an ornamental tree.

Various Trees

Washington also has a few trees that don't fit into the big category. For example, the chokeberry is a small tree that produces berries and has few uses other than protecting the soil and providing a small amount of food for animals.

Cascara wood has no commercial use, but its bark is used to make a laxative.

Pacific madrone has reddish brown, scaly bark and grows only near salt water. It has broad leaves but does not shed them in winter.

Oregon Ash grows all along the coast but is used only occasionally for firewood.

In the mountains of Washington State

Washington State is located on Western United States and refers to the Pacific States of the United States. Washington State Territory - 184,827 km 2 (18th place among US states).

Washington is the most northwestern of the US contiguous states. It borders with Canada to the north, Idaho to the east, and Oregon in the south. In the west, the coast of the state is washed by the waters of the Pacific Ocean.

Washington State is located in the US Pacific Time Zone.

Washington State is known as the "land of contrasts". On its territory you can see high mountains and river valleys, rain forests and semi-deserts.

Three main physiographic regions are distinguished on the territory of the state: valleys and plateaus in the east, mountain ranges in central Washington and the ocean coast to the west.

The eastern part of the state is formed by the Columbia Plateau, a vast plateau located between the Rockies and the Cascades. mountains, part of the Intermountain Plateaus of the United States. The cascading mountains interfere with the saturated moisture air masses from the Pacific Ocean reach the eastern regions of the state, so the climate here is quite arid. By the rolling steppes flows from north to south, forming a large arc, the largest in the northwestern United States Columbia River. At the confluence of the Snake River, the Columbia turns west, forming the southern border of the state.

Southeast Washington Rolling Plains

Mount Shaksan in northern Washington

The Cascade Mountains stretch from north to south in central Washington State. Here are several volcanoes included in the Pacific Ring of Fire: Baker, Glacier Peak, St. Helens, Adams. All of them are considered active, the last eruption of Mount St. Helens at 1980 was accompanied strong earthquake and claimed fifty-seven lives.

Ninety kilometers southeast of Seattle is the state's highest mountain, Rainier (4,392 meters above sea level). seas). This is a huge dormant volcano, the last eruption of which took place about one hundred and fifty years ago. because of proximity to a major city and huge glaciers located on the side of a mountain, Mount Rainier is considered potentially the most dangerous volcano in the continental United States.

Mount Rainier is the highest mountain in the state of Washington

On the coast of the Olympic Peninsula

In the western part of the state, on the Olympic Peninsula, there are the Olympic Mountains of the same name, reaching a height of 2427 meters above sea level. Between the Olympic and Cascade mountains along the rugged numerous bays and fjords Puget Sound stretched coastal lowlands.

The Western Districts of Washington State is one of the "rainiest" regions in the US. Mountain the ridges create the so-called "rain shadow effect", when moisture brought by the winds from the ocean falls on the western slopes, encouraging vegetation growth. Rainforests, usually characteristic of tropical climates, grow here in conditions of moderate temperatures, creating a unique ecological environment.

The features of the relief of the state also determine the features of the climate. For areas west of the Cascades characterized by a very large amount of precipitation and a rather mild climate with warm winters and relatively small seasonal temperature fluctuations. The average January temperature in the coastal Puget Sound the state's largest city, Seattle, fluctuates between 3°C and 8°C, with temperatures typically hovering around 13°C in July up to 24°C.
