Book excerpt: "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 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.

This book was released on 1997-03-07 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2018 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salt marsh ecosystems are prized for the numerous ecological and economic services that benefit society. On the U.S. east coast, virtually all salt marsh habitat from Maine to Virginia has been hydrologically degraded by the creation of mosquito ditches. In the 1930s, mosquito ditches were excavated throughout marshes to drain standing water and reduce mosquito breeding habitat. Investigations of mosquito ditches found that ditching had including lowered water tables and salinities, changed plant communities, and reduced habitat for fish and waterfowl species. A large scale effort to fill mosquito ditches and restore natural hydrology is on-going at Assateague Island National Seashore, Maryland. I investigated the impact of ditch filling at Assateague on plant species Spartina alterniflora and Salicornia. The percent cover and occupancy of Spartina alterniflora and the occupancy of Salicornia species were similar between ditched and unditched salt marshes before ditch filling was conducted. Following ditch filling, there was little evidence that ditch filling altered percent cover and occupancy in an ecologically meaningful way. I also tested the hypothesis that ditch filling would lower salinities in unvegetated marsh panne habitat and facilitate the establishment of S. alterniflora using transplants. Ditch filling did not appear to alter porewater salinities and though transplant survivorship was generally low across all marsh types, transplants in ditch-filled marshes exhibited 20% greater annual survivorship compared to ditched marshes. In a broader context, filling ditches is one of several ways to alter mosquito ditches for a desired hydrological impact. Ditch plugging, Open Marsh Water Management, and ditch remediation have also been used to alter marsh hydrology in order to achieve management desires. However, each technique involves uncertainty in outcome and impacts both in the short and long term. Practitioners of these techniques were interviewed to describe their approach towards this uncertainty and how they evaluated risk-versus-reward scenarios. Practitioners expressed similar responses towards approaching the ecological uncertainty of these techniques. Each championed the notions of starting pilot studies before larger efforts were initiated, the importance of ecosystem processes (such as vertical accretion), and that uncertainty in outcome should not inhibit trial-and-error approaches to restoring salt marsh hydrology.

Available in PDF, EPUB and Kindle. Book excerpt: Just a century ago some 625,000 acres of salt, brackish, and freshwater marshes bordered the Atlantic coast from Maine to Virginia. As early as 1885, however, work was begun to reclaim for agriculture considerable acreages of the fresher tidal lands. This research was conducted to study the effects of marshland drainage on plants, wildlife and wildlife habitat.
