The timber supply forecasts propose harvesting levels that may have impacts on fish, wildlife and biodiversity. The forecasted harvest levels will create younger forests on much of the accessible area. This will have negative consequences for some wildlife species that depend on older forests, as well as for biodiversity conservation. Depending on the location and rate of timber harvesting, fragmentation of wildlife habitats can also be high, making it difficult for some species to follow natural movement patterns. Potential loss of critical habitats for wildlife species that are dependant on older forests, such as mule deer, caribou and grizzly bear, is also a concern. There may be positive impacts for some species, such as moose, whose habitat includes younger forests. (SEA page 66)
If it is not properly managed increased road access may have negative impacts on wildlife and fisheries species through increased hunting and fishing pressure, and on sensitive habitats, such as riparian zones.
