Beaver are worth little on the current fur market. Small ones bring less than $10 and it takes a good one to bring much above $15. They are also tough to skin and flesh so many trappers are not targeting them. Beavers are very valuable making wet lands that benefit other forms of wildlife from waterfowl to many other bird species. When beavers move into an area they can deplete their food supply in a short length of time (frequently aspen trees and other soft woods) and it can take a dozen or more years for it to regenerate. Thus, they are forced to move on to new locations. In many areas there are fewer good places for them to inhabit.
