Wetland restoration essay

Monitor and adapt where changes are necessary. For example, restoring the bottom elevation in a wetland can be critical for reestablishing the hydrological regime, natural disturbance cycles and nutrient fluxes.

Structure and function are closely linked in river corridors, lakes, wetlands, estuaries and other aquatic resources. Natural Products for Our Economy We use a wealth of natural products from wetlands, including fish and shellfish, blueberries, cranberries, timber and wild rice.

Before actively altering a restoration site, determine whether passive restoration i. Protecting wetlands can protect our safety and welfare. Applicants seeking credit for specialized wetland courses taken outside of the university setting where no official college credit was generated must provide the following information to assist the SWSPCP in assessing the applicability or the course in meeting the minimum hour requirement for Specialized Wetland Courses: Reestablishing the appropriate natural structure can bring back beneficial functions.

The combination of shallow water, high levels of nutrients and primary productivity is ideal for the development of organisms that form the base of the food web and feed many species of fish, amphibians, shellfish and insects.

The holding capacity of wetlands helps control floods and prevents water logging of crops. Structurally, physical features such as the dimensions of its stream channels are dynamically stable.

Monitoring before and during the project is crucial for finding out whether goals are being achieved. Particularly in the planning stage, it is critical to focus on whether the proposed restoration activity is feasible, taking into account scientific, financial, social and other considerations.

For some rivers and streams, passive restoration can re-establish stable channels and floodplains, regrow riparian vegetation and improve in-stream habitats without a specific restoration project.

Why are Wetlands Important?

For the four measured parameters, the restored marshes performed comparably to or exceeded levels measured in reference marshes. High maintenance approaches not only add costs to the restoration project, but also make its long-term success dependent upon human and financial resources that may not always be available.

Therefore, it is essential to identify the causes of degradation and eliminate or remediate ongoing stresses wherever possible. Fifteen 15 semester hours in biological sciences including courses such as general biology, botany or zoology; general ecology; plant, animal, aquatic or wetlands ecology; invertebrate zoology; taxonomy; marine science; fisheries biology; plant physiology, plant taxonomy, plant pathology, plant morphology; relevant environmental sciences; and similar courses.

Use a reference site. Without continued use of herbicides, Phragmites grew back, becoming reestablished over extensive areas within 1 or 2 years Phillipp and Field, Perhaps the best way to ensure the long-term viability of a restored area is to minimize the need for continuous maintenance of the site, such as supplying artificial sources of water, vegetation management, or frequent repairing of damage done by high water events.

Phragmites-infested marshes were treated with aerial application of herbicides followed by prescribed fire. Beaver may actually create their own wetlands.

Universities, government agencies and private organizations may be able to provide useful information and expertise to help ensure that restoration projects are based on well-balanced and thorough plans.

Please relate these area s of expertise to your academic training, specialized wetland course work, wetland-related work experience, and wetland science.

Thus wetlands help to moderate global climate conditions. In some situations, it may also be necessary to consider downstream modifications such as dams and channelization. While it is possible to use historic information on sites that have been altered or destroyed, historic conditions may be unknown and it may be most useful to identify an existing, relatively healthy, similar site as a guide for your project.

Wetland Restoration

Wetlands and People Far from being useless, disease-ridden places, wetlands provide values that no other ecosystem can.

Growth rates of young-of-the-year Atlantic croaker also were comparable in restored and reference marshes Miller and Able, Restoration strives for the greatest progress toward ecological integrity achievable within the current limits of the watershed, by using designs that favor the natural processes and communities that have sustained native ecosystems through time.

This is why wetlands in Texas, North Carolina and Alaska differ from one another. Relevant experience may be gained while working in the private e. Bioengineering techniques can often be successful for erosion control and bank stabilization, flood mitigation and even water treatment.Wetland Restoration - A Photo Essay.


Historically, wetland restoration has been the primary focal point for the Partners for Fish and Wildlife program. Of million acres of wetlands that once existed across the United States in. In the spring ofHEI embarked on a major wetland restoration project with the Rice Creek Watershed District (RCWD).

The wetland, located in Columbus, Minnesota, had become ecologically degraded mainly from to the presence of a public drainage system.

Wetlands "Wetlands" is the collective term for marshes, swamps, bogs, and similar areas. Wetlands are found in flat vegetated areas, in depressions on the landscape, and between water and dry land along the edges of streams, rivers, lakes, and coastlines.

Mar 07,  · Most wetland restoration efforts have failed to restore wetlands to the same structure and function as it was historically or to that of a reference wetland (Zedler and CallawayNational Research CouncilSeabloom and van der Valk ).

Wetland restoration and creation proposals must be viewed with great care, particularly where promises are made to restore or recreate a natural system in exchange for a permit to destroy or degrade an existing more or less natural system (Abalone, p).
