Non-native and native plant species distributions and variability along an elevation gradient in the Wallowa Mountains, Oregon

Creator:

Averett, Joshua P.

Abstract:

Invasion by non-native plants into natural areas is an important component of global change that threatens biodiversity and ecosystem structure and function. Mountains are currently among the least invaded ecosystems, however, these biodiversity hotspots are increasingly under threat of exotic plant invasion. Evaluation of plant species distribution patterns in mountain...

The effects of timber harvest and herbivory on understory vegetation and composition of beef cattle diets on forested rangelands

Creator:

Walburger, Kenric J.

Abstract:

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...
