The Utah Forest Dynamics Plot (UFDP) is located in the Colorado Plateau ecoregion of the Intermountain West of North America (a). The high elevation (mean, 3081 m) results in cooler temperatures and higher precipitation than in the lower elevation portions of the Great Basin (b). The UFDP encompasses 15.32 ha (blue outline, of which, 13.64 ha analyzed here) and features a surveyed 20-m grid (c), with planar Brown’s transects measured along red lines (c). Panel a digital elevation model shows shading from the Shuttle Radar Topography Mission (2000); panel c topographic lines are a 5-m digital elevation model derived from LIDAR (2018). Shading in panel b is from a composite of Landsat 8 scenes (2014–2020). The orthophoto in panel c is from USDA National Agricultural Imagery Program (NAIP) data (2018)
