Predicting stocking improvement in reproduction stands of Douglas-fir.

Abstract

Some cut or burned-over Douglas-fir areas restocked promptly and fully. Others do not and seemingly never will restock adequately without the help of artificial seeding or planting. On some areas widely scattered seedlings become established and grow; filling-in is by second generation trees from the seed of these scattered parents. On still other areas stocking improves gradually over a period of years. The apparent inconsistencies and wide differences in rates of restocking are often disconcerting to the forester striving for stands of good density, and trying to determine if he should plant to obtain them.
