Impacts Of Supplemental Feeding On The Nutritional Ecology Of Black Bears, Steven T. Partridge, Dale L. Nolte, Georg J. Ziegltrum, Charles T. Robbins
Impacts Of Supplemental Feeding On The Nutritional Ecology Of Black Bears, Steven T. Partridge, Dale L. Nolte, Georg J. Ziegltrum, Charles T. Robbins

Black bear (Ursus americanus) damage to managed conifer stands during the spring in the U.S. Pacific Northwest is a continuing management concern. Because bear damage to managed conifers may reflect the limited availability of nutritious foods, supplemental feeding has been used to decrease damage. Highly palatable, pelleted feed is provided ad libitum from April until late June when berries ripen and such damage stops. We examined black bear use of supplemental feed during the spring and summer of 1998 and 1999 in western Washington. Bears were captured in areas where supplemental feed was provided and in control areas …

Bear Behavior In The Vicinity Of Supplemental Feeding Stations In Western Washington, Dale L. Nolte, Timothy J. Veenendaal, Georg J. Ziegltrum, Philipp Fersterer
Bear Behavior In The Vicinity Of Supplemental Feeding Stations In Western Washington, Dale L. Nolte, Timothy J. Veenendaal, Georg J. Ziegltrum, Philipp Fersterer

Black bear can inflict severe negative Impacts on timber stands in the northwestern United States. A supplemental feeding program to provide bears an alternative food source during spring is practiced in the state of Washington, and to a lesser extent in other states. We initiated concurrent studies to assess characteristics of bear that forage at feeding stations, the interactions of bears around feeders, and impacts of the program on bear territories. Numerous bears fed at stations, including females with and without cubs, yearlings, and males. Bear feeding bouts at stations were generally short, less than 15 minutes. Bears generally fed …

Black bears (Ursus americanus) are a valued resource in North America but pose many challenges to resource managers. They may be managed in 1 or more ways, including sustained yield harvests, nuisance animal control, or conservation management. Many black bear populations are stable or increasing, and combine with expanding human populations, increased development, and recreational activities, are leading to an increase in human-bear conflicts. Historically, methods such as relocation, general hunting seasons, or special hunts have been used in an effort to reduce bear density and damage, or to target individual offending animals. Many resource managers now operate …
