Site index and selected soil, climatic, and topographic characteristics were recorded for 72 one-fifth acre plots in well-stocked, even-aged lodgepole pine (Pinus contorta Dougl.) stands in north-central Colorado and south-central Wyoming. Within the range of the area examined, site index can be estimated using four environmental variables: (1) percent of soil particles larger than 0.25 mm. in diameter in the A horizon; (2) total solum depth in inches; (3) estimated percent of surface stoniness; and (4) average annual precipitation in inches. The prediction equation derived from multiple regression analysis accounted for 78 percent of the variance in site index, with most variation (58 percent) due to particle size.
