  • Pre-Sandy Conditions Despite a long history of intense development, Jamaica Bay is rich

    in fish and wildlife communities, with large and diverse populations

    of resident and migratory species.

    Jamaica Bay is recognized by the U.S. Fish and Wildlife Service as

    valuable habitat for migrating birds along the Atlantic. Some of these

    species have special regulatory protections under the Endangered

    Species Act, Migratory Bird Treaty Act, and state-level protections.

    The U.S. Fish and Wildlife Service estimates that nearly 20% of North

    Americas bird species migrate through or breed in the Jamaica Bay

    area.

    The West Pond freshwater wetland habitat of pre-Sandy conditions,

    unique and rare within Jamaica Bay, was a significant factor in the

    diversity of species.

  • Hurricane Sandy

    West Pond was breached and inundated with sea water from

    Jamaica Bay, which has continued to increase salinity, create

    tidally influenced conditions, and change the habitat composition

    from brackish to more saline conditions.

    The existing breach continues to widen and is vulnerable to future

    damage from storm activity and erosion.

    Storm Damage

  • Post-Hurricane Sandy Currently, due to the loss of the freshwater wetlands, the West

    Pond does not provide habitat that supports the diversity of

    species that existed pre-Sandy.

    Loss of the loop-trail affected the visitor use and experience.

    Although the West Pond area continues to provide excellent

    habitat for shorebirds, waterbirds with freshwater associations

    have declined.

    National Audubon Society and Cornell Lab of Ornithology data

    from 2011-2014 show a decline in species since the breach to West

    Pond.

    Visitation numbers for the Jamaica Bay Wildlife Refuge have

    dropped significantly since Hurricane Sandy.

    A 37% reduction in visitation occurred between 2011 and 2014.
