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.

Old-growth forests of the Acadian Forest Region

Environmental Reviews, 2003
In the absence of sufficient data from directed studies of old-growth forests in the Acadian Forest Region (AFR), we must rely on a general knowledge of forest ecology and natural succession, population biology, disturbance dynamics, and palynological evidence to understand the probable extent of old-growth, late-successional forest types before ...

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.

Old-Growth Forests Can Accumulate Carbon in Soils

Science, 2006
Old-growth forests have traditionally been considered negligible as carbon sinks because carbon uptake has been thought to be balanced by respiration. We show that the top 20-centimeter soil layer in preserved old-growth forests in southern China accumulated atmospheric carbon at an unexpectedly high average rate of 0.61 megagrams of carbon hectare-1 ...

Relictual Amphibians and Old‐Growth Forests

Conservation Biology, 1990
Abstract: Terrestrial and aquatic herpetofauna were sampled by pitfall traps, time‐constrained searches, and area‐constrained searches (stream sites only) over a three‐year period to examine the importance of forest age to amphibians and reptiles.
