Book Description
Excerpt from Fifty-Year Development of Douglas-Fir Stands Planted at Various Spacings Whereas current annual volume increment of the total stand has declined with increasing age, c.a.i. Of the 100 largest trees per acre has tended to remain nearly constant over the past 24 years. Mean annual incre ment is near culmination at close spacings, but is still far short of culmination at wide spacings. The impact of mortality has been minor at wide spacings. At close spacings, however, much mortality was the result of snow and ice damage, which affected groups of trees and created open ings in the crown canopy. This has reduced occupancy of the site and caused a further indirect loss in usable production. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
