An Uninhabited, Undeveloped Barrier Island. (Under the Direction of Thomas R ABSTRACT ROSENFELD, KRISTEN MARIE. Ecology of Bird Island, North Carolina: an uninhabited, undeveloped barrier island. (Under the direction of Thomas R. Wentworth.) Barrier islands include some of the most endangered and fragmented ecosystems on the Atlantic coast, providing critical habitat for many species, including some that are threatened and endangered. As the vast majority of these islands have been developed for human usage study and protection of the few remaining undeveloped and undisturbed islands is critical. This study was undertaken in order to characterize the vascular plant communities on Bird Island, an uninhabited, undeveloped barrier island on the border of North and South Carolina, with the objectives of a thorough survey of flora, vegetation, and environment, classification of plant communities, and multivariate analysis of vegetation and environmental data. A floristic inventory of the island and its associated marshes was conducted during the growing season (May- November) of 2002 and 2003. One hundred four 100m2 plots were inventoried for vegetation and environment using protocols developed by the Carolina Vegetation Survey. Plant communities were identified according to the National Vegetation Classification, the Classification of the Natural Communities of North Carolina, and the Carolina Vegetation Survey. Interpretation of vegetation patterns was based on multivariate analysis of vegetation and environmental data. Ninety-one vascular plant species in 35 families, including 4 exotic species, were distributed across 12 communities. Communities on Bird Island appear to be distinctive when compared to those described for other barrier islands in the region. Additionally, the vegetation survey on Bird Island revealed suitable habitat for the federally listed Seabeach amaranth (Amaranthus pumilus); an important dune-building annual of the North American Atlantic coast. Surveys of the late 1980s and early 1990s documented small populations of Seabeach amaranth on Bird Island, but our work found no indication of a population in either 2002 or 2003. Seabeach amaranth’s existence range-wide is threatened by habitat loss and fragmentation, herbivory, and anthropogenic disturbances such as beach driving, hardening, and raking. Published work on this species has been limited, but observations of natural, experimental, and restored populations have indicated relationships between distance from the ocean and both survivorship and reproduction. To quantify this relationship, 314 plants were transplanted at varying distances from the ocean. Plants were monitored monthly from June until December 2003. We found that distance from the ocean had a significant effect on survivorship, size, and reproduction; however, presence of webworms and ghost crabs did not have significant effects on size or reproduction. Distance from the ocean combined with complex factors such as over wash and soil salinity appear to be important indicators of success for both natural and restored populations of this species, and landscape position should be incorporated into future conservation and restoration efforts for A. pumilus in the Carolinas and elsewhere. Overall, we found that the vegetation of Bird Island is mostly intact, with few exotic, invasive species present. Bird Island’s protected status and limited presence of invasive species make it suitable habitat for continued protection and further restoration of rare, threatened, or endangered species, such as Seabeach amaranth. Atlantic barrier islands in general provide distinct community types combined with a small species pool, a combination that may provide a model for examination of larger ecological questions. ECOLOGY OF BIRD ISLAND, NORTH CAROLINA: AN UNINHABITED, UNDEVELOPED BARRIER ISLAND By KRISTEN MARIE ROSENFELD A thesis submitted to the Graduate Faculty of North Carolina State University in partial fulfillment of the requirements for the Degree of Master of Science BOTANY Raleigh, North Carolina 2004 APPROVED BY: Dr. Heather M. Cheshire Dr. Robert K. Peet Dr. John B. Taggart Dr. Qui Yun (Jenny) Xiang Dr. Thomas R. Wentworth Chair of Advisory Committee DEDICATION This is dedicated to my husband, David, and my parents, Bob & June Kostelnik. Their love, patience, participation, and support have allowed me to believe and achieve. ii BIOGRAPHY I grew up in the varied environments of the San Francisco Bay area of California and the foothills of North Carolina. Both these places, while vastly different, shaped my appreciation and love for the outdoors, particularly the coast. This connection to nature manifested itself early on as something that influenced my hobbies and extra curricular interests, but not as a career. The years following my undergraduate experience at Appalachian State University were spent in a rewarding career in business. I enjoyed these years in business and learned a great deal, but I knew that eventually I wanted to pursue further education in a natural sciences field that I was passionate about and one that would “make a difference”. I left my career and spent some time soul searching, taking classes, and discovering a hidden passion for teaching. During this time, I encountered the plant ecology work of Dr. Thomas R. Wentworth, a dedicated teacher. I knew this was the sort of work that would allow me to combine my interests in a meaningful way. My time in the graduate program at North Carolina State University has allowed me to deepen my commitment to a career in ecology, conservation, and education. I plan to complete my Master of Science in Botany in August 2004 and continue at NCSU in pursuit of my Ph.D. iii ACKNOWLEDGMENTS I thank my advisory committee of Drs. Heather Cheshire, Bob Peet, John Taggart, and Jenny Xiang for their guidance and active participation throughout the course of my study. I particularly thank the chair of my committee, Dr. Tom Wentworth. He has been a role model, inspiration, teacher, mentor, cheerleader, and friend without whom this work would not have been possible. I also thank Dr. Gerald Van Dyke whose confidence in my ability to get accepted and to succeed in graduate school inspired my application in the first place. Lastly, I thank Ellen Damschen and Dale Suiter for their professional advice and more importantly, their personal friendship. I cannot imagine having made it down this road without them. iv TABLE OF CONTENTS Page LIST OF TABLES................................................................................................ vii LIST OF FIGURES ............................................................................................. viii PREFACE................................................................................................................1 VASCULAR PLANT COMMUNITIES OF A CAROLINA BARRIER ISLAND...........................................................................3 Abstract........................................................................................................3 Introduction..................................................................................................4 Methods........................................................................................................6 Study Site.........................................................................................6 Sampling Methods...........................................................................7 Data Analysis...................................................................................9 Results and Discussion..............................................................................11 Flora ...............................................................................................11 Comparative Community Classification and Description .............13 Diversity.........................................................................................21 Environmental Interpretation.........................................................22 Conclusions................................................................................................23 Species List................................................................................................25 Acknowledgments......................................................................................29 References..................................................................................................30 THE EFFECT OF DISTANCE FROM THE OCEAN ON SURVIVORSHIP, SIZE, AND REPRODUCTION OF THE THREATENED BEACH PLANT, SEABEACH AMARANTH (AMARANTHUS PUMILUS RAFINESQUE)...............................44 Abstract......................................................................................................44 Introduction................................................................................................44 Methods......................................................................................................48 Study Species.................................................................................48 Study Site.......................................................................................49 Planting and Monitoring................................................................50 Data Analysis.................................................................................51 Results ........................................................................................................53 Survivorship...................................................................................53 Plant Size.......................................................................................53

  • Amaranthus Pumilus (Seabeach Amaranth)
    Bartonia No. 61, 2002-News and Notes Amaranthus pumilus Raf. (Seabeach Amaranth, Amaranthaceae) Rediscovered in Sussex County, Delaware In August of 2000, Amaranthus pumilus was rediscovered in Sussex Co., Delaware after 125 years without a sighting. It was first collected in Delaware in 1875 by Albert Commons (10 September 1875, A. Commons, s.n., "seabeach, Baltimore Hundred, Delaware," PH). Amaranthus pumilus was federally listed as threatened by the U.S. Fish and Wildlife Service in 1993. Historically, this species was known from Massachusetts south to South Carolina (Weakley et al. 1996). Amaranthus pumilus was reported as rediscovered at Assateague Island National Seashore, Worcester County, Maryland in 1998 (Ramsey 2000). Prior to rediscovery on Assateague Island and in Sussex County, A. pumilus was extant on Long Island, New York, and in North Carolina and South Carolina. Lisa Marie Kendall of the Delaware Natural Heritage Program, Division of Fish and Wildlife, Delaware Department of Natural Resources discovered the first plants on 7 August 2000. Subsequent surveys revealed a total of 41 individuals scattered over 22 kilometers of Atlantic shoreline. All plants found are within the boundaries of Delaware Seashore and Fenwick Island State Parks. The largest number of plants (28) was found within a 1.5-km stretch of shoreline near the swimming beach at Delaware Seashore State Park. This section of beach is the only area where A. pumilus was found that is off-limits to vehicular traffic. This area provides the best habitat for the long-term survival of A. pumilus. Individual plants were found growing on relatively open sand near the base of the primary foredune.

A noxious weed is defined as “any plant or plant product that can directly or indirectly injure or cause damage to crops (including nursery stock or plant products), livestock, poultry, or other interests of agriculture, irrigation, navigation, the natural resources of the United States, the public health, or the environment” (7 U.S.C. § 7701-7786, 2000). We use weed risk assessment (WRA)—specifically, the PPQ WRA model (Koop et al., 2012)—to evaluate the risk potential of plants, including those newly detected in the United States, those proposed for import, and those emerging as weeds elsewhere in the world. Because the PPQ WRA model is geographically and climatically neutral, it can be used to evaluate the baseline invasive/weed potential of any plant species for the entire United States or for any area within it.

  • Sea-Beach Amaranth Amaranthus Pumilus Rafinesque
    Endangered Plants of New Jersey Fact Sheet Sea-beach Amaranth Amaranthus pumilus Rafinesque Summary Sea-beach amaranth is an annual plant of the Amaranth family (Amaranthaceae) that exhibits low sprawling growth and small spinach-like leaves, and is restricted to open sandy portions of ocean beaches between the high tide line and the toe of the primary dune. It was first collected in the early Nineteenth Century in New Jersey, and its range was subsequently determined to extend from Massachusetts to South Carolina. Although originally described as abundant, the number of populations of A. pumilus declined precipitously throughout the Twentieth Century and, following a collection from Ocean County in 1913, vanished from the flora of New Jersey. Habitat destruction and alteration, incompatible beach grooming practices and recreational activities have all contributed to the decline of this species. By 1989, the species was restricted to a few populations in North and South Carolina. In 1991 New Jersey included A. pumilus in its first official Endangered Plant Species List, and in 1993 the U.S. Department of the Interior, Fish and Wildlife Service, determined A. pumilus to be a federally threatened species under the authority of the Endangered Species Act. In 2000 the plant returned to newly created beaches in Monmouth County and adjacent habitat in Sandy Hook. Intensive surveys performed in 2001 revealed populations or individuals in all four coastal New Jersey counties. Despite its reappearance, the plant remains highly vulnerable to the uses and practices that caused its extirpation throughout most of the previous Century. Description following dispersal. Individuals are occasionally found on back dunes, exposed shoals, dune blowouts and bayside An annual plant that exhibits low, relatively prostrate strands, although these occurrences tend to be small and growth with fleshy, rounded, dark green leaves (1-2 cm temporary.

    Surveys for the Federally-Listed Threatened Plant Species, Seabeach Amaranth (Amaranthus pumilus), in Keansburg, NJ May 19, 2012 Jay F. Kelly, Ph.D. Round Mountain Ecological LLC 74 Old Highway 28 Whitehouse Station, NJ 08889 [email protected] (908) 534-0053 Introduction Seabeach amaranth (Amaranthus pumilus Raf.) is an herbaceous annual plant in the Amaranthaceae that occurs on sandy, ocean beaches in eastern North America. The habitat of A. pumilus is restricted to the narrow strip of land between the high tide line and the base of the dunes, and significant impacts to these areas by coastal development, hard shoreline stabilization, incompatible land use practices, and severe storms have resulted in major declines in the species’ populations throughout its range (USFWS 1996). The species is currently listed as Threatened by the U.S. Fish and Wildlife Service (USFWS 1996), and Endangered by the New Jersey Department of Environmental Protection (NJDEP 2010). Although there are no historic records documenting the presence of seabeach amaranth in Keansburg, NJ, this portion of the Raritan Bay contains ample suitable habitat for the species and is in close proximity to the largest populations of the species in the State, in Sandy Hook. Although surveys of these areas in 2010-2011 found no A. pumilus, the exceptional seed banking and dispersal capabilities of this annual plant species make repeated surveys necessary to effectively document the presence or absence of the species in a given area. Results - Amaranthus pumilus This report presents the results of surveys conducted for seabeach amaranth in Keansburg, NJ, prior to the beach replenishment planned for May 2012.

  • A Report to the Aquatic Nuisance Species Task Force for 2011 - 2012
    A Report to the Aquatic Nuisance Species Task Force for 2011 - 2012 Summary The mission of the Mid-Atlantic Panel (MAP) is to assist state and federal agencies and other stakeholders in developing and implementing strategic, coordinated, and action-oriented approaches to prevention and control of aquatic invasive species (AIS) in the mid-Atlantic region. The driving force behind the Panel’s mission is to strengthen cooperation, coordination, and communication on AIS issues within the region and beyond. The Panel conducts an annual small grants competition to fund on-the-ground activities addressing MAP’s mission and regional priorities. There is particular interest in vector management. Since 2007, the Panel has awarded nearly a quarter million dollars leveraging over half a million dollars in partner funds (Attachment 1). The MAP met twice in 2011 with the spring meeting held May 18-19 at the National Wildlife Visitor Center in Laurel, Maryland. Projects selected for 2011 funding at this meeting targeted nutria, beach vitex, and Asiatic sand sedge eradication and the mapping of invasive species in the Ohio River Basin (Attachment 2). The fall meeting was held October 5-6 at the National Conservation Training Center in Shepherdstown, West Virginia. Tim Schaeffer of the Pennsylvania Fish and Boat Commission discussed the broad challenges of Asian carp management. Professors Zachary Loughman of West Liberty University and Tom Jones of Marshall University presented their research on non-native crayfish of significant concern in West Virginia. The important results of the first telemetry study conducted for rusty crayfish in the central Appalachian region were also highlighted.
