Book excerpt: "In 1982 the Massachusetts Audubon Society, the Essex County Mosquito Control Project, and the Manomet Bird Observatory began a research program to adopt OMWM [Open Marsh Water Management] for mosquito control on New England salt marshes. The methods we have developed are presented in this manual for those who would like to practice OMWM in Massachusetts and other areas of the Northeast. Step by step procedures are outlined and several options are described."--Leaf I-1.

This book was released on 2018 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salt marshes have been modified for mosquito control since the early 1900s. Open marsh water management (OMWM) is a mosquito control technique first applied in New Jersey in the 1950s. It has been extensively used in the mid-Atlantic and also in Massachusetts, New York, Connecticut, Florida, and Louisiana. This practice involves excavation of areas of marsh, constructing shallow ponds to provide habitat for mosquito larvae-eating fish with the goal of reducing mosquito populations. Nearly half of Barnegat Bay, New Jersey’s coastal marshes have been subject to OMWM since 1976, and its effects on ecosystem function are not well understood. Here, we assess the impacts of OMWM on the carbon balance of salt marshes associated with the conversion of intact vegetation to open water ponds. Using a precise object-based image analysis classification technique, we found that over 7,000 ponds, approximately 3% of Barnegat Bay’s coastal marshes, have been constructed for mosquito control. Using state of the art IR technology to examine in-situ greenhouse gas fluxes in Barnegat Bay, we found evidence to suggest that the conversion from intact plants to open water ponds negatively shifted the carbon balance of the salt marsh, both within the footprint of the constructed pond as well as within the area where deposition of sediment has prevented the recolonization of marsh vegetation. We conclude that this management technique has significantly reduced the carbon sequestration capacity of Barnegat Bay’s tidal wetlands.

Available in PDF, EPUB and Kindle. Book excerpt: Salt marshes are productive ecosystems that provide critical breeding and foraging habitat for many bird species. Open marsh water management (OMWM), a method of mosquito abatement through habitat alteration, is a widely practiced management technique in Mid-Atlantic salt marshes. Although OMWM may alleviate the need for pesticide applications, the effect of these habitat modifications on obligate salt marsh breeding birds is not fully understood and remains an information priority for the United States Fish & Wildlife Service National Wildlife Refuge System. My objectives were to; (1) develop a method to quantify OMWM, (2) use an index of marsh bird community integrity to evaluate the effect of OMWM, and (3) determine the impacts of OMWM on Seaside Sparrow reproductive success and nesting ecology. I searched for and monitored nesting birds, performed callback and passive surveys, and estimated vegetation cover on 19 plots (1-3ha) within tidal marshes in Sussex County, Delaware in May-August 2006-2007. I categorized plots as limited (n = 10) or extensive OMWM (n = 9) based on the level of OMWM manipulations. I detected 29 species across all surveyed plots, but detected no difference in species richness between limited and extensive OMWM (P = 0.145). I defined four avian guilds: salt marsh obligates, wetland generalists, shorebirds, and gulls/terns to compare avian communities between limited and extensive OMWM. Only the relative abundance of the salt marsh obligate guild differed between limited and extensive OMWM and was more than 1.5 greater on limited OMWM sites than extensive sites (P = 0.015). Relative abundance of Seaside Sparrows was 2.5 times greater on limited OMWM than on extensive OMWM (P = 0.002). Seaside Sparrow territory density (P = 0.002) and nesting density (P = 0.031) was also 2 times greater on limited OMWM plots than extensive OMWM plots. Nest survival rates were similar (P = 0.584). However, when comparing measures of productivity between limited and extensive OMWM, I found the number of Seaside Sparrow eggs/ha (P = 0.026) and fledglings/ha (P = 0.053) were greater on limited OMWM plots. Seaside Sparrow nest survival rates did not differ between levels of OMWM, but reproductive output was greater on areas with limited OMWM. OMWM does not appear to benefit most marsh bird species or guilds, but may negatively impact populations of salt marsh obligate species and Seaside Sparrows. OMWM may be used as an alternative means of mosquito control, but should not be considered a method of habitat enhancement for obligate salt marsh bird species. Refuges concerned with protecting populations of Seaside Sparrows or other salt marsh obligate birds should limit amounts OMWM in high breeding areas.

Available in PDF, EPUB and Kindle. Book excerpt: Many coastal tidal marshes have been significantly degraded by roadways and other projects that restrict tidal flows, limiting their ability to provide vital ecosystem services including support of fish and wildlife populations, flood protection, water quality maintenance, and open space. Tidal Marsh Restoration provides the scientific foundation and practical guidance necessary for coastal zone stewards to initiate salt marsh tidal restoration programs. The book compiles, synthesizes, and interprets the current state of knowledge on the science and practice of salt marsh restoration, bringing together leaders across a range of disciplines in the sciences (hydrology, soils, vegetation, zoology), engineering (hydraulics, modeling), and public policy, with coastal managers who offer an abundance of practical insight and guidance on the development of programs. The work presents in-depth information from New England and Atlantic Canada, where the practice of restoring tidal flow to salt marshes has been ongoing for decades, and shows how that experience can inform restoration efforts around the world. Students and researchers involved in restoration science will find the technical syntheses, presentation of new concepts, and identification of research needs to be especially useful as they formulate research and monitoring questions, and interpret research findings. Tidal Marsh Restoration is an essential work for managers, planners, regulators, environmental and engineering consultants, and others engaged in planning, designing, and implementing projects or programs aimed at restoring tidal flow to tide-restricted or diked salt marshes.
