Polman and M.M.G.R. Bol.   To examine the effects of density control and fertilization on stand growth and yield of young Douglas-fir (Pseudotsuga menziesii (Mirb.)

Douglas-Fir Seedling Grows 8 Feet Tall in Two Seasons Donald Copes, Frank Sorensen, and Roy Silen ABSTRACT.-A inch-tall coastal Douglas-ir (Pseudo­ tsuga menziesii [Mirb.]Franco) seedling was grown from seed in two years. Greenhouse temperatures of 60° to 70° F, a six-month growing season, long day, adequate. Douglas-ir yield projctions to total age 45 yeas from three diferent models for naturally regenerated stand or planted stands on a foot (year breast height age) site index. Trees.   Growth & Yield. Predicting the future growth and yield of your forest stand(s) is an essential part of the planning process for your forest land. This page will provide you with a basic understanding of the concepts of growth and yield. A look at these concepts in the context of even- and uneven-age stand structure will also be provided. present in the two States about , acres of Douglas fir second growth on cut -over lands. Over half of this 5,, acres is pri- vately owned. A survey made in by the Forest Service on 5,, acres of national forests within the Douglas fir zone showed 2,, acres of Douglas fir under years old. From this survey.

stand volumes given current growth rates. Mean annual increment (MAI) This is the average volume growth per year over the life of the stand. Periodic annual increment (PAI) This is the annual volume growth measured over a specified period, usually 5 or 10 years. We recommend you use the growth over the past 5 years to calculate PAI. The following definitions of stand density and stocking are recognized by the Society of American Foresters (): Stand density — A quantitative measure of tree stocking ex- pressed either relatively as a coefficient, taking normal num- bers, basal area, or volume (from yield table data) as unity; or absolutely, in terms of number of trees. chemical preparation. release treatments. chemical release. growth. tree/stand health. regeneration.
