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 …

Black bear (Ursus americanus) damage to coniferous forests can be detrimental to the forest products industry in Washington state. Value of timber damage, west of the Cascade Mountains is millions of dollars every year. The Washington Forest Protection Association’s (WFPA) Animal Damage Control Program (ADCP) manages bear damage in cooperation with the Washington Department of Fish and Wildlife (WDFW). Bears can significantly affect the viability of other wildlife, for example, elk (Cervus elaphus) calf predation on calving sites. Conversely, bear-damaged trees add to the snags and dead wood on the ground, which provide important habitat and …
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 …
Effect Of Feeding Stations On The Home Ranges Of American Black Bears In Western Washington, Philipp Fersterer, Dale L. Nolte, Georg J. Ziegltrum, Hartmut Gossow
Effect Of Feeding Stations On The Home Ranges Of American Black Bears In Western Washington, Philipp Fersterer, Dale L. Nolte, Georg J. Ziegltrum, Hartmut Gossow

Forest managers establish feeding stations throughout coniferous forests in western Washington that are vulnerable to American black bear (Ursus americanus) damage in the spring. This study was conducted to determine whether the home ranges of bears in areas with supplemental feeding were smaller than the home ranges of bears in similar adjacent areas without supplemental feeding. Home range sizes varied among bears. However, the home range sizes of bears in feeding areas did not differ (P > 0.35) from home ranges of bears in non-feeding areas. Male bears had larger (P = 0.0002) home ranges than female …
