Old attitudes die hard and some people may consider the mere presence of a beaver to be a problem. They may not be aware that these peaceful animals make good neighbors, and removing beavers often creates more problems than coexistence.
Removing beavers tends to be a short-term fix as others will normally migrate into the empty habitat. Beaver kits need to stay with their parents for two years, and any removal of adults risks leaving dependent youngsters behind. Orphaned beaver babies have been known to swim up to humans for help, and, if then taken to a wildlife rehabilitator, that person must devote considerable time, energy and expense raising them over two years.
When beavers are taken away, their dams will disintegrate without constant repairs and the pond will be drained. Some pond residents, such as herons, will be able to migrate, but many fish and other creatures will die. Neighbors of such destroyed ponds are often dismayed by the loss of life and muddy mess left behind.
