Regenerating Adirondack Northern Hardwoods By Shelterwood Cutting and Control of Deer Density
Abstract:Shelterwood cuttings to regenerate old-growth northern hardwoods in the Adirondack Mountains reduced the overstory to 50 square feet per acre of basal area. Precutting application of herbicides had killed understory vegetation composed predominantly of American beech (Fagus grandifolia Ehrh.). Intensive hunting had reduced deer density from 27 to 14 per square mile. Sugar maple (Acer saccharum Marsh.) dominated regeneration two years after seed cutting, but yellow birch (Betula alleghaniensis Britton) was tallest on more sample milacre plots six and ten years after seed cutting. At age 10, tallest saplings averaged 12 feet in height and 0.8 inch d.b.h., and 4,800 stems per acre had grown above 8 feet. Beech was present only in small numbers and tallest on no more than 20 percent of plots at all ages. Seed cutting, herbicide treatments, and deer density control successfully favored yellow birch and sugar maple over less desirable beech.

- 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.
