After a series of devastating forest fires in the 1930s, the temperate rainforest in the Oregon area that would later become Tillamook State Forest was nearly irreversibly damaged. Thanks to the massive efforts of the Oregon Department of Forestry and thousands of volunteers, over 72 million tree seedlings were planted. Up until 2019, this effort was the world’s largest reforestation project. Tillamook State Forest was officially established in 1973 to grant it extra protections from logging and mining enterprises. As a temperate rainforest, the region receives over 100 inches of rainfall annually, which makes it one of the wettest areas in the United States.
