Abstract

In this study, height-diameter equations were developed for managed stands of coastal redwood/Douglas-fir stands in Mendocino County. Equations were developed by species to predict tree height as a function of diameter as well as other factors that are known to potentially explain tree height, including site class and live crown ratio. Two equation forms were compared and evaluated. Forest inventory data from Jackson Demonstration State Forest were used to fit the equations. These height-diameter equations will be useful in explaining height-diameter relationships in largely uneven-aged coastal redwood/Douglas-fir stands, and for predicting missing heights in forest inventories.
