    Piping plover habitat and demography following storm-induced and engineered landscape change Samantha Grace Robinson Dissertation submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy In Fisheries and Wildlife Conservation James D. Fraser (Co-Chair) Daniel H. Catlin (Co-Chair) Sarah M. Karpanty Stephen P. Prisley March 19, 2020 Blacksburg, Virginia Keywords: behavior, Charadrius melodus, habitat creation, habitat selection, Hurricane Sandy, population dynamics, survival © 2020, Samantha G. Robinson Piping plover habitat and demography following storm-induced and engineered landscape change Samantha Grace Robinson ACADEMIC ABSTRACT Understanding the effects of large-scale disturbances and associated management actions on imperiled species can increase conservation value of future management. Piping plovers (Charadrius melodus; plover) are federally threatened and endangered, disturbance-dependent shorebirds, nesting on broad, sparsely vegetated beaches, sandbars, and lakeshores. In October 2012, Hurricane Sandy storm surges cleared vegetation and opened old and new inlets through Fire Island and Westhampton Island, New York, creating plover habitat. Storm effects prompted an island-wide stabilization project, and certain sections of Fire Island were designed to create and/or improve plover habitat (hereafter, restoration areas) to mitigate possible habitat loss or degradation. Many plover populations range-wide appear to be habitat-limited, and we anticipated positive population growth following habitat creation. To help predict what might happen to the plover population following Hurricane Sandy, we evaluated the effects of habitat-creating events at several other locations in the range, evaluating the hypothesis that plover population sizes are habitat limited.

Cuthbert May 2010 © Erin Anne Roche 2010 ii Acknowledgments To my committee: I would like to thank Francie Cuthbert for many things but above all for taking a chance on me, Dave Smith for pushing me to be more aggressive while schooling me in sensitivity, Bob Zink for his continual support and entertainment and finally Todd Arnold for going above and beyond at basically everything. I want to acknowledge Cathy Haffner, Liz Price, Mark Westbrock, Jennifer Stucker and Lauren Wemmer for ensuring banding efforts were continued annually over the past 17 years. Thank you to Alice Van Zoeren for her dedication to resighting Great Lakes plovers (even in the bitter cold of April) and her patience with me over the past years as I learned to be a field biologist. Finally, without the combined efforts of employees and volunteers of the National Park Service, U.S. Forest Service, U.S. Fish and Wildlife Service, Wisconsin Department of Natural Resources, Michigan Department of Natural Resources, the Nature Conservancy, Lake Superior Land Conservancy, Lake Superior State University, Bad River Tribe, and Little Traverse Bay band I would not have the wealth of data available to conduct the demographic analyses presented in this dissertation.

  • 2016 Update Atlantic Coast Piping Plover Population
    ABUNDANCE AND PRODUCTIVITY ESTIMATES – 2016 UPDATE ATLANTIC COAST PIPING PLOVER POPULATION Population monitoring on the breeding grounds has been an integral part of the recovery program for Atlantic Coast piping plovers since 1986, providing information to inform protection of breeding piping plovers and their habitat. Annual coastwide censuses are one component of monitoring that track local and regional progress toward recovery. This update describes the delisting criteria established in the recovery plan, discusses the role of abundance and distribution of breeding pairs in Atlantic Coast piping plover conservation, and summarizes the most current information about abundance and productivity. Recovery criteria and strategy The objective of the 1996 revised Atlantic Coast Recovery Plan is to assure the long-term viability of the Atlantic Coast piping plover population in the wild, thereby allowing removal of this population from the Federal List of Endangered and Threatened Wildlife and Plants (50 CFR 17.11 and 17.12). The Atlantic Coast piping plover population may be considered for delisting when the following recovery criteria, established in the recovery plan, have been met: 1. Increase and maintain for 5 years a total of 2,000 breeding pairs, distributed among four recovery units. Recovery Unit Minimum Subpopulation Atlantic (Eastern) Canada1 400 pairs New England 625 pairs New York-New Jersey 575 pairs Southern (DE-MD-VA-NC) 400 pairs 2. Verify the adequacy of a 2,000-pair population of piping plovers to maintain heterozygosity and allelic diversity over the long term. 3. Achieve a 5-year average productivity of 1.5 fledged chicks per pair in each of the four recovery units described in criterion 1, based on data from sites that collectively support at least 90 percent of the recovery unit’s population2.

  • Piping Plover Info Sheet
    CONSERVE WILDLIFE FOUNDATION OF NEW JERSEY PIPING PLOVER Charadrius melodus Identification The piping plover is a small shorebird with a black neck band and a black bar across the forehead. The upperparts are light sandy-brown and the underparts are white, providing camouflage against sandy beach backgrounds. The legs are bright orange and, in breeding plumage, the bill is also orange with a black tip. Although males and females are similar in appearance, males typically have darker, more extensive neck bands. The call of the piping plover is a ventriloquist-like peep-lo which is often heard before the bird is seen. Juvenile and winter-plumage adults are similar in appearance. Both lack the black neck and forehead bands characteristic of breeding adults. Rather, there is a pale band around the neck. The bill is solid black and the legs are pale yellow. Distribution & Habitat In New Jersey, piping plovers breed on Atlantic Coast beaches from Sandy Hook to Cape May. Migrant plovers are present from early March to mid-April and from mid-July to late September. Females depart first during fall migration from their breeding grounds, followed by males, then juveniles. Piping plovers inhabit oceanfront beaches and barrier islands, typically nesting on the stretch of beach between the dunes and the high-tide line. Nests are often located in flat areas with shell fragments and sparse vegetation. The coloration of piping plovers and their eggs blend in remarkably with sand © Chris Davidson and broken pieces of shell. Plovers may nest in sparse vegetation, as it provides cover against predators and the elements.

  • Piping Plover: an Endangered Species
    December 2013 [Revised] Piping Plover FACT SHEET Piping Plover: An Endangered Species Background The piping plover is an endangered shorebird that nests and feeds along coastal sand and gravel beaches. The adults can be recognized by their size, shape and colouring. They are about the same size as a sparrow, and have orange legs, a black band across their foreheads from eye to eye, and a black ring around their necks. Their body is sand-coloured, which helps them blend into their surroundings. Male and female piping plovers take Population and Range turns incubating eggs. The piping plover has been on the endangered species ©Parks Canada/Don Pentz list since 1982 and has seen a declining trend in population size. In 2013, there were only 389 plover pairs in eastern Canada. This species ranges from Canada to the United States and the Caribbean. They are here in Canada for the summer months – around the Great Lakes in Ontario, in the Prairie Provinces and in Atlantic Canada, where they can be found in each of the four provinces. In the winter, they migrate to the southern United States and the Caribbean. Nests Piping plovers usually arrive in Atlantic Canada in April to establish nesting areas and form pairs. Their nest is a small depression in the sand, just above the high tide line, which may contain a few small shells and rocks for camouflage. They usually lay four eggs. Both adults help Piping plovers will stop feeding when with incubation and after about 26 days, the young hatch. humans get too close.
