Wetlands function as natural sponges that trap and slowly release surface water, rain, snowmelt, groundwater and flood waters. Trees, root mats and other wetland vegetation also slow the speed of flood waters and distribute them more slowly over the floodplain.

That being so, what role do wetlands play in keeping water clean?
Water Quality: Wetlands act as natural water purifiers, filtering sediment and absorbing many pollutants in surface waters. In some wetland systems, this cleansing function also enhances the quality of groundwater supplies.
Secondly, how do wetlands improve water quality quizlet? Wetlands reduce flooding and erosion by filtering water. ... Wetlands reduce flooding and erosion through decreased vegetation.
Just, what are 3 benefits of wetlands?
Wetlands provide many societal benefits: food and habitat for fish and wildlife, including threatened and endangered species; water quality improvement; flood storage; shoreline erosion control; economically beneficial natural products for human use; and opportunities for recreation, education, and research (Figure 28) ...
What is a wetland and why is it important?
Why are wetlands important? Wetlands associated with streams and rivers slow down floodwaters by acting as giant shallow pans. Water flowing into these pans loses speed and spreads out. Plants in the wetland play an important role in holding back the water.

Destruction of Wetlands Destroys the habitat of many birds and fish; Removes the natural filters capable of storing and degrading many pollutants, such as phosphorus and heavy metals; Destroys natural dams and causes flooding further downstream.
Wetlands can help reduce the damage caused by hurricanes by protecting coasts from storm surges. Storm surges are an effect from hurricanes.
Conserve water every day. Take shorter showers, fix leaks & turn off the water when not in use. Don't pour toxic household chemicals down the drain; take them to a hazardous waste center. Use hardy plants that require little or no watering, fertilizers or pesticides in your yard.
water quality - wetlands function like filters by removing polluting nutrients and sediments from surface and groundwater.
wetlands are important because of their sheltered waters and rich supply of nutrients, wetlands provide habitats for many living things. many species of animals live in wetlands year-round. ... wetlands act as natural water filters. They also help with flood control from heavy rains by the water being absorbed.
Wetlands reduce flooding and erosion by filtering water. Wetlands reduce flooding and erosion by absorbing water and then releasing it slowly. Wetlands reduce flooding and erosion through decreased vegetation. B) Wetlands reduce flooding and erosion by absorbing water and then releasing it slowly.

- Groundwater recharge and stream flow maintenance.
Wetlands contribute to the national and local economies by producing resources, enabling recreational activities and providing other benefits, such as pollution control and flood protection. ... A wetland is a natural area that is often wet but may not be wet all year round.
The water in wetlands is either freshwater, brackish, or saltwater. There are four main kinds of wetlands – marsh, swamp, bog and fen (bogs and fens being types of mires). Some experts also recognize wet meadows and aquatic ecosystems as additional wetland types.
Wetlands play a vital role in the health of the environment. In addition to supporting a variety of organisms, they also reduce water erosion by trapping sediments. Wetlands help clean water by absorbing nutrients that are added to the water supply through agriculture and industry.
Wetlands provide habitat for thousands of species of aquatic and terrestrial plants and animals. Wetlands are valuable for flood protection, water quality improvement, shoreline erosion control, natural products, recreation, and aesthetics.
Wetlands are important to us as they remove pollution, recharge groundwater supplies, control floods, and provide home for variety of plants and animals. ... Wetlands are the most productive habitats on the planet as they contain high number of plant and animal species including mammals, bird, fish and invertebrates.
Water is essential to humans as well as all other forms of life. Wetlands are important for maintaining fresh water supplies. They catch and store rain water, refill underground reserves and protect them from salty water. ... Wetlands break the force of storms and lessen the amount of damage.
Water quality is influenced by many factors like precipitation, climate, soil type, vegetation, geology, flow conditions, ground water and human activities. ... Activities like mining, Urban development and Agriculture also effect water quality.
They provide food and habitat for a diverse array of plants and animals, act as buffers to flooding and erosion, and serve as key links in the global water cycle. Because of their sponge-like ability to absorb water, wetlands can slow the momentum of flood waters or of a coastal storm surge.
Water Quality & Habitat RestorationPlant Trees. Trees provide shade to lower water temperature and stabilize streambanks to reduce erosion.Remove Invasive Plants. Invasive species decrease biodiversity and often crowd out native species.Protect Streambanks From Livestock. ... Create Log Jams.
Wetlands prevent flooding by temporarily storing and slowly releasing stormwater. Wetlands also reduce water flow, thus allowing sediments and associated pollutants to settle out. ... In addition, roots of wetland vegetation hold soils in place, thus stabilizing the banks of rivers and streams.
America's Wetlands Wetlands are areas where water covers soil all or part of the time. Wetlands are important because they protect and improve water quality, provide fish and wildlife habitats, store floodwaters and maintain surface water flow during dry periods.
Wetlands reduced damages in most locations, but not everywhere. In some parts of North Carolina and the Chesapeake Bay, wetlands redirected the surge in ways that protected properties directly behind them, but caused greater flooding to other properties, mainly in front of the marshes.
Improve sanitation facilities by providing toilets and latrines that flush into a sewer or safe enclosure. Promote good hygiene habits through education. Proper hand washing with soap and water can reduce diarrhea cases by up to 35 percent.

The economic benefits to wetlands are numerous as well. Improved water quality, flood control, wildlife and fisheries habitat, and recreational opportunities are just a few economic benefits that wetlands provide. Wetlands are an important, yet often overlooked, resource.
b) Ecologically, (1) they provide a habitat for various wildlife and (2) provide nutrient cycling, or soak up excess nutrients. Economically, (1) they provide a location for fishing and other sources of recreation and (2) reduce flooding and erosion.
Wetlands must have one or more of the following three attributes: 1) at least periodically, the land supports predominantly hydrophytes; 2) the substrate is predominantly undrained hydric soil; and 3) the substrate is saturated with water or covered by shallow water at some time during the growing season of each year.
Freshwater swamps often form on flat land around lakes or streams, where the water table is high and runoff is slow. Seasonal flooding and rainwater cause the water level in these swamps to fluctuate, or change. Water-tolerant plants, such as cattails, lotus, and cypress, grow in the swamp's wet soil.
Why are wetlands important to migratory birds? A. More than one third of the 1900 North American bird species use wetlands for breeding, nesting, as a source of drinking water and for shelter, social interactions and rearing their young.
