Due to the widespread and often intense land-use practices of Euro-Americans, particularly circa 1880 to 1930, past human activity is an important component of the pattern and process

Anästhesie. Fragen und Antwortenthan 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. 2012; figure 9-1). With this forest recovery and an increasing abundance of old-growth stands,

To the forest visitor, the distinctive above-ground structure of the old-growth forest is most visible and striking: towering trees, multiple canopy layers, large snags, and coarse woody debris. Hidden from view is an equally complex belowground world that has largely escape

There were also those who saw little value in managing for old-growth features, perceiving this as a threat to more traditional management objectives

However, recent research has questioned that assumption, showing that eastern old-growth forests may remain productive and have net positive carbon uptake later into succession and stand
