Evidence of long-term survival and reproduction by translocated river otters, Lutra canadensis

During 1982-1984, the authors reintroduced 26 river otters into pine and Kettle Creek drainages, Allegheny Plateau, Pennsylvania. In 1990 and 1991, otter scats were frequently encountered along both streams, demonstrating that otters have remained at release areas six to eight years. Evidence gathered from otters accidentally caught by trappers at reintroduction areas demonstrated that six of nine otters trapped at Pine Creek and two of four at Kettle Creek had been reproduced by the respective reintroduced populations. -from Authors
