History and significance:
The Douglas fir's expansive greenery led to Washington's nickname as the Evergreen State. Douglas firs line millions of square miles of Northwest hillsides and valleys. The tree is named for Scottish plant explorer David Douglas, who sent seeds of the species to England in 1827. The tallest of these trees in Olympic National Park stands at 326 feet. The trunks can reach almost 15 feet in diameter. It is one of the world's most important timber trees.
