Body
Effects of elk browsing on willows following simulated beaver use were examined to determine if heavy elk browsing on riparian willows was causing the beaver population to decline. This three year study was conducted in Rocky Moutain National Park, Co in two parks that historically recieved heavly elk browing on willow populations. Beaver use was simulated by cutting willows at ground level, three years later willows within paired plots (browsed, non-browsed) were measured. Utilization rate by elk was approximately 85%.
