Ornithological Summary

Provides critical habitat for Piping Plovers.

Conservation Issues

Great Lakes Piping Plovers face many threats in the breeding areas limiting both survivorship of adults and young as well as fecundity, including:

1) Predation of adults and young by raptors (esp. Merlin), gulls, and mammals 2) Disturbance of incubation/trampling of eggs and nests by foot traffic and ORVs 3) Botulism poisoning of adults eating maggots from botulism-killed waterbirds washed up on beach

Cordoning off of the breeding territories and volunteer efforts of the Piping Plover patrol are now required long-term for the continued survival of this population. Avoiding burying botulism-killed waterbirds is necessary to prevent the occurrence of botulism infested maggots in the breeding areas.
