Influence of Markets on Sustainability of Forests


The Northern Research Station has realigned our staff from 37 Research Work Units and Programs into 14 new Research Work Units.

RWU-4805 is now part of NRS-5, Forest Inventory and Analysis .

Our Mission

To examine interrelationships between forest product markets and the composition, structure, and sustainability of the eastern hardwood forest.


Eastern hardwood forests are continually influenced by bio-physical forces and human disturbance. Although the role of disturbance on the forest formation is not fully understood, there has been continuous research on the impact of bio-physical disturbance agents such as climate, fire, animal populations, and exotic species on the forest composition, structure, and sustainability. By contrast, the impact of human disturbance has been viewed primarily in terms of broad aggregates such as total anticipated softwood or hardwood fiber and sawtimber demand. Such research is important in assessing long-term aggregate timber supplies but provides little information on the effect of humans on forest composition, structure, and sustainability. This is unfortunate because human disturbance probably will continue to shape privately held hardwood forests in the Eastern United States.

More Information

This site is under development as the Forest Service brings together the Northeastern and North Central Research Stations to form the Northern Research Station, serving the Northeast and Midwest. Check back often as we expand our site to reflect our combined commitment to supporting the natural resources and people of the Northeastern and Midwestern United States.
