Publisher's Synopsis
Excerpt from Red Oak and White Ash, Vol. 4: A Study of Growth and Yield
The question of the yield Of unmanaged second growth hardwood stands has been fully considered and the results are given in Harvard Forest Bulletin no. 2, Growth Study and Normal Yield Tables for Second Growth Hardwood Stands in Central New England, by J. Nelson Spaeth. Since in these stands, arising from the cutting of both pine and hardwood, the most valuable trees are oak and ash and, also, since a great percentage of the young growth consists of these two trees, it is Obvious that the forest Of the next rota tion will be largely an oak - ash stand. This type is now fully recognized by the silvicultural policy on the Harvard Forest, partly because of the great value Of these two species and partly because of the prohibitive cost of reconstituting pine stands on the better soils. As these forests are situated in a region Of wood-using industries where practically every load of lumber can be sold, as well as cordwood, they can be placed under intensive management. This has already been begun on the Harvard Forest, and the purpose of the present study was to Obtain data for the purposes of future manage ment. The specific questions for determination were, there fore, rotation and density as related to growth, tree form, and value of yield.
