We are not allowed to translocate or release captured beaver in another area. The law requires consent of a property owner, and the site must be remote. The sad truth is that the majority of translocated animals are unable to survive in their new environments, undermining the purpose of translocation.
Large cage traps, rotating-frame body grip traps and cable restraints are all options, depending on site specific conditions, local ordinances and appropriateness of their use in a particular area.
Recolonization is most likely to occur during dispersals and the building of food caches, typically in the spring and fall. A site may remain vacant for many years, or it may be recolonized during the next dispersal period. Site specific conditions raise or lower the likelihood of this event, but generally speaking the potential always exists.
A beaver colony must be removed before a dam is cleared, or it will be rebuilt immediately. The Minnesota Department of Natural Resources states that in some instances lakeshore has been developed based on the water levels controlled by an established dam. In those situations a DNR Area Hydrologist should be consulted before any changes are made.
Beaver slap their tails to alert their colony to danger, frighten an encroaching beaver, or to startle an enemy into revealing its location.
