Clearcutting and the Biogeochemistry of Streamwater in New England
Abstract:A survey shows that clearcutting in New England may increase stream nutrients, including nitrate-nitrogen, calcium, and potassium. The largest increases were found in northern hardwoods in New Hampshire. Stream insect populations, particularly mayflies and true flies, increased in clearcuts in response to increased stream temperature, algal populations, and organic matter. Changes in streamwater chemistry and biology indicate that clearcutting forestlands does affect streams throughout New England. However, the magnitude of differences is such that if erosion and sedimentation are controlled, clearcutting as practiced by foresters today does not drastically change streamwater chemistry or biology.

More about this publication?
- The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
