Growth intercept models relate site index to early tree height growth. To develop this model for lodgepole pine (Pinus contorta var. latifolia), 45 stem-analysis plots were sampled in northern British Columbia and another 45 plots were sampled in southern British Columbia. Tests were performed to detect differences in the site index-growth intercept relationship between the northern and southern plots. No practical differences were found, therefore one model suffices for both regions. This model should replace the existing model for lodgepole pine because it is more widely applicable in British Columbia.
