http://www.paws.org/beavers.html Features of the Riparian Zone -Restores and stabilizes soil
-Protects aquatic environments from sedimentation
-Improves water quality
-Supplies food and Shelter Ideal Conditions -Slow moving rivers, streams, lakes, or ponds
-Lots of trees nearby for dam building and food

A beaver will alter its environments to suit its needs FOOD WEB Wolves Mountain Lion Coyotes Hawks Tree Bark (Aspen and poplar) Bears Aquatic plants Berries Beaver How humans have affected beavers Beavers were once hunted into near extinction. They have been trapped for their pelts and landowners also kill them because they build dams that cause flooding. As a result, beaver populations have dropped dramatically. What humans can do to reduce/eliminate problems People can change their property to prevent beavers from building dams.
Fencing an area can prevent beavers from entering it.
Placing a wire mesh around trees discourages beavers from using the trees to build their dams
Cutting fewer less trees
Not planting anything beavers eat near houses Effect on food web and beaver Humans are cutting down more trees, forcing beavers to travel further away from their homes to find food, leaving them vulnerable to predators.
