| Canada geese fly in a 'V' formation to reduce their energy costs. Each bird is able to take advantage of the reduced wind resistance behind the lead birds. To avoid turbulence they fly at high altitudes. |  |

Managing Coastal Forests to Save the Habitat of the Black Bear

Habitat loss
Black bears need to hibernate in protected dens to survive British Columbia's harsh winters. Biologists from Simon Fraser University, British Columbia, tracked bears in the Nimpkish Valley in southwestern British Columbia and discovered that bears rely on large trees, stumps and logs for their dens. These structures are often destroyed during commercial timber harvesting. This work, along with other research to develop forest management and conservation plans, will ensure that crucial black bear denning habitat is maintained.
