Abstract or Summary
  • The objectives of the experiment were to: 1) determine the relationship between overstory canopy cover and ungulate herbivory on understory production composition and diversity and 2) determine the effects of timber harvest, ungulate herbivory and season of use on botanical composition and nutritional quality of beef cattle diets. Three randomly selected grand fir (Abies grandis) and ponderosa pine (Pinus ponderosa) sites were established in 1986. Timber harvest and herbivory treatments were arranged in a spilt-plot design.
