Abstract
Most individual-tree based growth and yield models use a 5- to 10-year time step, which can make projections for a fast-growing species like red alder quite difficult. Further, it is rather cumbersome to simulate the effects of intensive silvicultural treatments such as thinning or pruning on a time step longer than one year given the highly dynamic nature of growth following treatment. The goal of this project was to provide preliminaly annualized individual tree diameter and height growth equations for untreated red alder using a technique that can incorporate data with varying remeasurement intervals. An additional modeling technique was used to partition out the variation in growth unexplained by attributes of the tree and stands and an attempt was made to relate it to installation edaphic characteristics.
