Effect of Logging on Forage Values for Deer in Colorado
Abstract:Plant species important for deer forage were collected three times in summer 1970 from clearcut and uncut strips in a lodgepole pine (Pinus contorta)-spruce-fir (Picea engelmannii-Abies lasiocarpa) forest 15 years after logging. Crude protein content, moisture content, and in vitro digestibility within a collection date did not differ statistically between clearcut and uncut strips. Crude protein and moisture content declined significantly between dates, but in vitro digestibility did not change as the plants matured. Because of greater species diversity and plant productivity, and because deer spent more time grazing in clearcut strips, they obtained over twice as much of their crude protein and digestible dry matter there.

- 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.
