Production and Utilization by Deer and Moose of Woody and Herbaceous Vegetation on Areas Commercially Clearcut in Northern Maine
- Stone, Timothy L.

Production of woody and herbaceous material available to ungulates was measured on areas commercially clearcut from 4-15 years previously. Vegetation was placed into the following categories: deciduous leaves, forbs, grasslike plants, ferns, raspberries. hardwood browse, balsam fir browse, and spruce browse. Production in all classes was higher in the clearcuts than in a mature spruce-fir stand also sampled.
Production by plant category was correlated with different site variables, using stepwise multiple regressions. Although many variables tested significant (P < 0.05), most were not highly correlated with production except with balsam fir (r2 =0.96) and total production of all vegetation classes combined (r2=0.50) The number of years since an area was clearcut did not explain how much of the variation in production.
