Forest-Stream Interactions in Eastern Old-Growth Forests

2018
The largescale recovery of eastern forests from historic clearing is a remarkable example of forest ecosystem resilience (Foster and Aber 2004). More than 150 years after the peak of agricultural clearing in eastern North America, many forests across the region have reached maturity and some are progressing toward an old-growth condition (Brooks et al.

Forest-Tree Value Growth Rates

Northern Journal of Applied Forestry, 1985
Abstract Rates of growth in the value of standing timber can vary greatly from stand to stand and from tree to tree. Faced with this variation, forest managers need guidelines to help determine financial rates of return for their woodlots. In Pennsylvania, the average annual tree value growth rate between 1965 and 1978 was 1.6%.

Compensatory Trends of Forest Growth

Ecology, 1974
Thinnings of forest stands invariably increase the diameter of trees, but not their heights. The question of why an augmented supply of light and water promotes the division of lateral cambial cells but not of the apical cells has so far failed to received a satisfactory answer from plants physiologists.

Old-Growth Forest and Jobs

1996
An optimal control model is constructed where the cutting of old-growth forest generates jobs and adds to the stock of land devoted to "newgrowth," rotational forestry. Welfare is determined by the number of jobs in the forest economy and the stock of old-growth forest, which provides "nontimber" benefits.

Growth Characteristics of Forest Trees

Journal of Forestry, 1963
Abstract The intermittent character of tree growth is reviewed. Different parts of trees grow at varying rates and at different times. Shoot growth of many Temperate Zone trees occupies a relatively short part of the frost-free season.
