Book Description
"A study was conducted to determine the effects of three mosquito control marsh management techniques on selected parameters of the ecology of a Distichlis spicata/Spartina patens dominated marsh in Somerset County, Maryland. The three water management techniques evaluated were: (1) open plot - ditches coupled to the estuary to allow unrestricted tidal exchange; (2) water control - structures placed in the outlet ditches to restrict tidal exchange; and (3) closed - not connected to the estuary by ditches. Two unditched areas served as controls."--Leaf iii.

This book contains papers on the topics of brought together wetland SCientists from all wetland ecology and management, most of continents and provided an opportunity to exchange valuable information on a variety of which were presented at the 2nd International Wetlands Conference in Trebon, Czechoslovakia aspects on the ecology and management of wetlands. (13-22 June 1984). The conference, hosted by the Hydrobotany Department of the Institute of Botany, was organized by the Czechoslovak This volume contains papers that represent aspects of wetland management. Like most Academy of Sciences and the International ecological topics, the papers clearly Wetlands Working Group of the International Association of Ecology (INTECOL) with demonstrate that the science of wetland management is not evenly developed around the cooperation from the SCOPE (SCientific Committee on Problems of the Environment) world. In some areas, wetlands have not even Working Group on Ecosystem Dynamics in been adequately described and there is little Freshwater Wetlands and Shallow Water Bodies, information about the impacts that man is UNESCO Man and the Biosphere (MAB) having on them. In other areas, information on Program, International Society for Ecological wetland ecology and management has developed Modelling, and the International Society for to the point where regulations and laws provide Limnology (SIL). Partial sponsorship for the some protection against development.

Book Description
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.

Book Description
This is a major compendium of the existing knowledge of the ecology and management of tidal marshes by some of the leading experts in the field. The major theme of the book is the interconnectedness of the marsh, plants, marine organisms, soils and geology, energy and money flow, and legal and management effects on the system. Emphasis is placed throughout on the fact that nature has provided a free service that can either be maintained and enhanced by man or destroyed and forever lost. At a time of declining fisheries, this book points the way to management strategies that are needed to effect improvement.
