Beaver once were so abundant in the Scott Valley in Siskiyou County, Calif., that it was known for a time as Beaver Valley.  The rodent’s numbers were decimated during the early days of settlement.

"Relocation" sounds like something out of the witness protection program, but it's the process of moving animals from one habitat to another. 

In the case of beavers in Klamath County, the relocation process is meant to put the beavers in the best place to help the environment and/or not create issues for farmers and ranchers.
