The Utah Forest Dynamics Plot (UFDP) is a research and educational project affiliated with the Utah State University, the Utah Agricultural Experiment Station, and the University of Montana. The UFDP is located in Cedar Breaks National Monument. It lies in high elevation, spruce-fir forests with a considerable pine and aspen component. The plot size is 13.2 ha. All trees ≥1 cm at breast height (1.37 m) are mapped, as are shrub species with with main stems ≥1 cm in diameter at 1.37 m. The genus Pinus (Pinus longaeva, Pinus flexilis, Pinus ponderosa, Pinus edulis) is mapped without respect to size - every stem two years and older is measured.
