The growth and development of individual sugar maple (Acer saccharum Marsh.) seedlings in fenced and unfenced quadrats beneath a partially cut stand were measured over a 5-year period. The effect of severe winter browsing on seedlings growing in environments favoring vigorous height growth was silviculturally insignificant. After 5 years, the dominant seedlings in the unfenced quadrats were 1.6 feet shorter because of the amount of leader browsed, but the rate of height growth and seedling density were unaffected; and the minimum stocking above deer reach was 5,000 seedlings per acre. Also, forks and the associated crook and sweep tended to correct naturally. Reasons are suggested for the reports elsewhere of adverse effects of browsing on sugar maple.

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.
