“...in 1969 and 1970, 59 otters were moved from Amchitka Island in Alaska to areas along the Washington coast...many animals were found washed ashore dead....It's estimated that the otters...are descended from as few as 10 animals.... In 2014, we counted a high of 1,573 otters....the increase...has been about eight percent per year—one of the highest growth rates for otters populations anywhere.”
