Small secretive shorebirds, Piping Plovers nest at the Seaside Adjunct, the coastal portion of Kejimkujik National Park. Parks Canada has undertaken an active program to protect the birds' nesting areas in an ongoing effort to prevent the plover's extinction. Human activity has taken its toll on plover nests. To minimize human disturbance and protect the Piping Plovers, part of St. Catherines River Beach, where the plovers nest, is closed to all public access while the birds are nesting. Beach access is permitted once the signs are removed, however pets must be kept on a leash at all times.
Natural predation is a major concern with local plover numbers being so low.
Raccoons were a concern and in past years steps were taken to remove these animals from the nesting areas. However, information from recent years indicates that predation by gulls and crows is now the primary threat to the successful fledging of plovers. In an effort to reduce predation of plover nests, circular wire mesh enclosures are placed around them. The enclosures help to increase the hatching success of chicks, however they do not help the fledglings. When the chicks leave the nest, and the safety of the enclosure, they again become vulnerable.
