Site description
The WFDP is located near Carson, WA in the Research Natural Area of the Gifford Pinchot National Forest, with the plot center at 45.82°N, -121.95°W. Elevation ranges from 352 m to 385 m for a vertical relief of 33 m (Fig. 1).

Figure 1. Topography of the Wind River Forest Dynamics Plot. The 20 m grid is shown on a LiDAR-derived digital elevation model of the plot (1 m horizontal resolution). The maximum elevation within the plot is 385 m; the minimum elevation is 352 m (5 m contours shown). LiDAR-derived bare-earth model courtesy of Watershed Sciences, Corvallis, Oregon.

Data sets
The WFDP was established around two existing permanent plots at the Wind River Field Station. A 4 ha plot around the Wind River Canopy Crane (now the Wind River NEON instrument tower) was established in 1994 (now in the northeast corner of the WFDP), and a larger 12 ha plot was established in 1999 (the eastern half of the WFDP).
