Forest Service research dates back almost to the time the national forests were created. The first study in the Pacific Northwest was started in 1909 to determine tree volume, taper, and bark thickness of hundreds of trees. Permanent growth plots were established on the Willamette National Forest in 1910. That same year research began at Wind River (Carson), Washington, to learn more about reforestation followinga wildfire. In 1913, the Wind River Forest Experiment Station was established as the first Forest Service research facility in the Pacific Northwest.
