Herring River Restoration

Giving full credit to restricting the Mississippi River as the culprit for loss of wetlands is not accurate. The booming oil and gas exploration of the 1970’s and 1980’s merits a name on the marquee as well. The pipelines and canals used to transport the resources to the outside world placed a great deal of stress on the fragile wetlands. Erosion from the barges in and out of the marshes as well as the salt water allowed into the fresh water, providing a precarious habitat for fresh water species – flora and fauna alike. Plants provide root systems to hold soil in place. Fish and fowl provide an economy for the area. Enter

McEwen supports these claim with examples, quotes from professionals, and reasoning. The purpose of his article was so he could make readers be aware that the river restoration plan won’t work.

Since 1930, over 2,300 square miles of wetlands have disappeared and recording about 23-25 square miles of wetlands are lost each year. “This is equivalent to losing a football field every thirty-eight minutes” (Losing Ground). Human and natural activities are at fault for the coastline destruction but human activities are the most responsible for having accelerated the amount of destruction. One major form of human activities that have hurt the coast was the construction of levees. Levees are man-made earthen hills that surround the Mississippi River, and many other bodies of water, and protect people from the natural flooding that occurs.

The Impact of Hydropower Dams on California's Populations of Anadromous Fish: What Can be done to mitigate the Dams Effects and Restore California's Watersheds.

In the four centuries since the explorations of Captain John Smith, the Chesapeake Bay has lost half of its forested shoreline, more than half its wetlands, nearly 80 percent of its underwater grasses, and more than 98 percent of its oysters. Across the watershed, approximately 1.7 million acres of once-untouched land were developed by 1950. Development has accelerated dramatically since then, with an

In addition, farmland has been destroyed because of the floods and the decrease in delta sediment. The dam has reduced downstream nutrients and sediment flow. And has seriously impacted neighboring river and seacoast ecosystems.

Along with this devastation, the New River which is the "most polluted waterway in the nation " (due heavily to its raw sewage content, agricultural drainage water and powerplant effluent ) that flows from Mexico and dead ends (literally) into the Salton Sea.(Salton Sea Authority and the Bureau of Reclamation, 1997) These two factors mentioned above are the main cause for the massive fish die off , bird die off, the speeding up process of eutrophication, five forms of predominant bacteria and contamination from DDT , selenium, Botulism , New Castle disease, as well as alga blooms and horrific odors.

There are a number of environmental advantages that would occur upon decommissioning the Edwards Dam, most notably the rejuvenation of fish populations and the resulting increase in numbers of the osprey and bald eagles which feed upon them. Historically, the Kennebec River provided extensive top-quality breeding grounds for all ten species of anadromous fish native to the northeastern U.S., a distinction that the Kennebec River alone could boast of. Anadromous fish make their home in the ocean but embark upon the tough journey upstream once a year to lay their eggs. Since the erection of the Edwards Dam in 1837, and the subsequent construction of more than a hundred dams upstream of the Edwards, these fish have been effectively blocked off from prime spawning grounds. The removal of the dam would open up fifteen miles of these grounds, seventeen miles total before encountering the next obstruction, making this the longest uninterrupted stretch of high quality breeding grounds north of the Hudson River (Howe,1998).

All of the 3,350 miles of riverine habitat within the pallid sturgeon's range have been affected by man. Approximately 28% has been impounded, which has created unsuitable lake-like habitat; 51% has been channelized into deep, uniform channels; the remaining 21% is downstream of dams which have altered the river's hydrograph, temperature and turbidity. Commercial fishing and environmental contaminants may have also played a role in the pallid sturgeon's decline. The resultant changes to the Missouri River in the upper Great Plains from channelization prevent upstream migration. The reduced water flow rates and sediment loads have brought an end to the seasonal flooding of the flood plains in the region.

The Pine Knoll Shores Aquarium Restoration project, it is one restoration project of many in the state of North Carolina that make up the North Carolina coastal restoration project responsible for the restoration of the 301 miles that make up the North Carolina coastlines. I have chosen this particular project because it is close to me; I worked an internship for my high school senior research project at the Aquarium at Pine Knoll Shores and worked closely with the rehabilitation of the endangered Loggerhead sea turtle.This ecosystem needed to be restored because of the effects of the Hurricane Irene in 2011, and the Longshore current. This current is responsible for eroding the coastline, moving north to south in a quick process that migrates inlets

Monitoring every one of the hassles that influence waterfront wetlands remains an issue for analysts attempting to recognize the impacts of the spill, each of the three scientists said. Notwithstanding storm surges, they indicated both the choice by Louisiana authorities to open all freshwater redirections along the Mississippi River after the spill. That additional crisp water to the swamps. The state openings were trailed by

Another element to the template design of a restoration site is the decision to excavate tidal channels and a drainage system. Oftentimes, project managers can choose to “rejuvenate pre-existing tidal drainage system by redirecting tidal flows into the area.” If the natural drainage system has become too shallow over time, one may choose to excavate channels that follow the original drainage network of the wetland. This decision can contribute significantly to the success of the wetland because the natural processes will be restored much more quickly than if the wetland was allowed to re-develop those channels on its own (Faber “Design” 47). Because the drainage systems function as valuable wildlife habitat, the Sears Point project took special care to establish the “antecedent channel configuration” by

The reason why Deptford Creek can be seen from photographs as a muddy tidal reach is because huge quantities of concrete was poured into it at strategic points to avoid the flooding which Deptford has always suffered

Dent and Pons, (1995) reported that in coastal wetlands with tidal swamps and inland marshes
