Supplemental Bear Feeding Program

Each spring black bears emerge from their dens hungry and with little available sources of food. During this time, as young conifers approach their annual spring bud burst, there is a high concentration of sapwood moving up the tree just inside the bark. This sapwood is rich in carbohydrates and can be a very attractive food source for hungry bears. The bears rip off the bark to eat the sapwood and in the process they often girdle and kill the trees. Bears can girdle up to 50-70 trees a day, and this loss can create a significant economic impact for forest landowners. By late June or early July there are plenty of natural foods for bears to eat, and generally damage to the young timber ends about this time.

Last month I attended a presentation by Georg Ziegltrum of the Washington Forest Protection Association (WFPA) at the Department of Natural Resources monthly breakfast meeting. Georg’s presentation was primarily about WFPA’s Black Bear Supplemental Bear Feeding Program, although he also talked about other components of the WFPA’s Animal Damage Control Program, including lethal control efforts.

In 1985 WFPA began the Black Bear Supplemental Feeding Program. In 2006, the Program used a total of 465,700 pounds of bear pellets at 860 feeding stations in Western Washington in an effort to reduce spring black bear damage to young private timberlands. The Black Bear Supplemental Feeding Program feeds black bears at special feeding stations for about 2 ½ months each year to provide a food source during the spring when food sources are limited. Young even-aged stands between 15 and 30 years of age are the most vulnerable to bear damage, and the supplemental feeding program has helped to reduce this damage.

However the Black Bear Supplemental Feeding Program does not prevent all damage to young timber stands. This program is used along with lethal control, in areas with heavy damage, to limit impacts to private forestlands. In 2006, Washington Department of Fish and Wildlife (WDFW), in cooperation with WFPA’s Animal Damage Control Program, issued about 190 depredation permits for black bears in areas where there was heavy timber damage on private forestland. Most of the bears are removed by hound hunters, although foot snares and bait are also occasionally used with depredation permits.

Continental Divide Ecosystem Grizzly Estimate


GREAT FALLS, Mont. (AP) — A study of grizzly bears in and around Glacier National Park estimates 240 of the bears live in a 2 million acre area. This is a 3,125 square mile area.

“It’s the first really rigorous population estimate for that area,” said Kate Kendall, a West Glacier-based research biologist with the U.S. Geological Survey, who led the study.

The Greater Glacier area includes the 1.1 million-acre national park plus 900,000 acres of surrounding grizzly habitat, including the Blackfeet Indian Reservation and lands west of Glacier to U.S. Highway 93. This arear is also known as the ‘Northern Continental Divide Ecosystem’.

Researchers estimated the population by collecting bear hairs in 1998 and 2000 and analyzing the DNA in each strand. The estimate is important because grizzly recovery efforts can’t be measured without reliable population figures, Kendall said.

In 1998 and 2000, researchers collected almost 15,000 bear hairs left behind at barbed wire “hair corrals” and natural bear rub trees evenly distributed across the 2 million acres. Individual bears can be identified from their hair because they contain DNA. The hair samples identified 185 unique bears in 1998 and 222 bears in 2000. Researchers used a statistical formula to arrive at the estimate of 240 bears.

Selway-Bitteroot Grizzly

Federal and state wildlife officials are investigating the killing of a grizzly bear in north-central Idaho, where the last confirmed sighting of the species was in 1946. That is over sixty years ago.

A hunter, from Tennessee, was on a guided trip hunting black bear with bait and killed the grizzly bear on Monday, September 3rd near Kelly Creek about three miles from the Montana border. Black bear hunting season opened Aug. 30.

The male grizzly weighed 400 to 500 pounds and was 6 to 8 years old. The hunter and guide skinned the carcass and brought it out on horseback so it could be confirmed as a grizzly by authorities. It is now in the possession of state fish and game department.

The bear killed was in the Selway-Bitterroot ecosystem that includes part of north-central Idaho and western Montana, and where wildlife officials have been expecting grizzly bears to repopulate on their own. The Selway-Bitteroot area is one of six recovery zones for grizzly bears in the lower 48 states. Prior to this sighting, no grizzlies were thought to be in the Selway-Bitteroot recovery zone.

The bear possibly came from the Cabinet-Yaak ecosystem in western Montana or the Northern Continental Divide ecosystem that includes Glacier National Park. DNA tests are planned to try and determine the bear’s origin.

Fish and Game officials had been telling black bear hunters that there were no grizzly bears in the area. He said hunters are now being warned that grizzlies are in the area, and that they are not legal to hunt.

Wildlife Highway Crossings

Hidden cameras let you spy on animals as they go about their business.

Dr. Tony Clevenger of the Western Transportation Institute at Montana State University has research video cameras that record the passage of a variety of large mammals using Banff National Park’s wildlife crossing structures under the TransCanada Highway.
