Studies have documented mass die-offs of benthic invertebrates following beach nourishment due to their burial under huge amounts of sand. The rate at which native invertebrate species recolonize restored areas can vary, and studies have documented that shorebird use of restored sites decreases with prey suppression. To better understand how invertebrate recolonization processes work in this unique delta ecosystem, we sampled invertebrates in 2013-2015 and 2019-present to compare the diversity and abundance of invertebrates in core samples taken from the intertidal zone before and after restoration. We also measure physical aspects of the sand, such as organic content and particle size, to use as covariates in statistical models." }, { "@type": "TextObject", "text": "The Isles Derni\u00e8res Barrier Island Refuge (IDBIR) is a chain of barrier islands on Louisiana\u2019s southeastern coast. Its name comes from the French phrase for \u201cLast Island,\u201d which refers to its historical state as a single large island on the edge of the Gulf. Today, the IDBIR includes four islands in Terrebonne Parish: Raccoon Island, Whiskey Island, Trinity/East Island, and Wine Island. The islands provide coastal communities and wetlands protection from storm surge and erosion and serve as critical habitat for wildlife species. The IDBIR has experienced a net loss of land over the last century. As a result of subsidence, hurricane damage, erosion, and loss of sediment input following the channelization of the Mississippi River, the IDBIR lost 82.2% of overall land area from 1887 to 2002. To combat this land loss, all islands in this chain have undergone restoration efforts such as beach nourishment. Though the goal is to increase overall land area, managers also aim to restore natural ecological processes; however, the timeline for the recovery of native species in restored areas is unknown." }, { "@type": "TextObject", "text": "The federally threatened piping plover relies on sand-beach habitat year-round for nesting, foraging, and roosting, habitat that is particularly vulnerable to loss and degradation from coastal development, recreation activities, erosion, and sea-level rise." }, { "@type": "TextObject", "text": "The Science Issue and Relevance: The piping plover is a small, pale gray shorebird that relies on the Gulf Coast for resources during the winter and migratory seasons. Coastal habitats like the open beaches, barrier islands, and sheltered bays that piping plovers prefer are particularly vulnerable to loss and degradation due to coastal development, recreation activities, erosion, and sea-level rise. Piping plovers were listed as federally protected under the Endangered Species Act in 1985 and remain threatened in the Gulf of Mexico. Louisiana barrier islands have supported 85% of the state\u2019s winter population, and surveys at Whiskey Island have documented up to 40 wintering piping plovers per year in recent decades." }, { "@type": "TextObject", "text": "Methodology for Addressing the Issue: The Coastal Protection and Restoration Authority implemented restoration projects on Whiskey Island in 2018 with the intent to create 954 acres of beach, dune, and marsh habitats. To assess the impact of restoration on piping plovers and other shorebird species of conservation concern, we conducted surveys before (2012-2017), during (2017-2018), and after the restoration period (2018-present). All suitable habitat on the island is surveyed bi-weekly from August to February and weekly from March to July. Binoculars and high-powered spotting scopes are used to identify piping plovers, red knots, nesting shore and seabirds, and all other avian species on Whiskey Island. During the surveys, we record species abundance and richness, habitat use, and behavior. Additionally, we search for birds uniquely marked with colored leg bands, which allows us to track movements and survival of individuals within the refuge and beyond. We also periodically conduct similar shorebird surveys on other islands within the IDBIR." }, { "@type": "TextObject", "text": "Future Steps: We plan to investigate habitat function on Whiskey Island for birds across the annual cycle. Bird data collected from 2012 through 2020 will be analyzed to determine changes in habitat, occupancy, and function on Whiskey Island before and after restoration. Additionally, we will evaluate the immediate impacts of severe storms on breeding birds to determine if productivity was negatively impacted; if so, how that relates to site-dependent factors; and how it varies across individual storm events." } ], "funder": { "@type": "Organization", "name": "Wetland and Aquatic Research Center", "url": "https://www.usgs.gov/centers/wetland-and-aquatic-research-center" }, "about": [ { "@type": "Thing", "name": "Monitoring" }, { "@type": "Thing", "name": "Threats" }, { "@type": "Thing", "name": "Biology" }, { "@type": "Thing", "name": "Environmental Health" }, { "@type": "Thing", "name": "Ecosystems" }, { "@type": "Thing", "name": "RESTORE PES" }, { "@type": "Thing", "name": "Restoration" }, { "@type": "Thing", "name": "Imperiled Species" }, { "@type": "Thing", "name": "Coastal" }, { "@type": "Thing", "name": "Climate Change" }, { "@type": "Thing", "name": "Geology" }, { "@type": "Thing", "name": "Science Technology" }, { "@type": "Thing", "name": "Surveys (Aerial, Shoreline)" }, { "@type": "Thing", "name": "Species of Management Concern" }, { "@type": "Thing", "name": "Birds" }, { "@type": "Thing", "name": "Invertebrates" }, { "@type": "Thing", "name": "Habitat Loss" }, { "@type": "Thing", "name": "Species Biology" }, { "@type": "Thing", "name": "Explore by Taxon" }, { "@type": "Thing", "name": "Coastal Ecology" }, { "@type": "Thing", "name": "Monitoring and Detection" }, { "@type": "Thing", "name": "Wildlife & Terrestrial Species" }, { "@type": "Thing", "name": "Migratory Birds" }, { "@type": "Thing", "name": "Energy" }, { "@type": "Thing", "name": "WARC SSP Goal 1" }, { "@type": "Thing", "name": "Management and Restoration" }, { "@type": "Thing", "name": "WARC SSP Goal 5" }, { "@type": "Thing", "name": "Priority Landscapes" }, { "@type": "Thing", "name": "Coastal land loss" }, { "@type": "Thing", "name": "Information Systems" }, { "@type": "Thing", "name": "Threatened and Endangered Species" }, { "@type": "Thing", "name": "Ecosystem Impacts" }, { "@type": "Thing", "name": "Methods and Analysis" }, { "@type": "Thing", "name": "Wildlife and Terrestrial Species" }, { "@type": "Thing", "name": "Water" }, { "@type": "Thing", "name": "Louisiana" }, { "@type": "Thing", "name": "Threatened and Endangered" }, { "@type": "Thing", "name": "Piping plovers" }, { "@type": "Thing", "name": "Explore by Location" }, { "@type": "Thing", "name": "migratory birds" }, { "@type": "Thing", "name": "Our Capacities" } ]
