Wetlands are very productive and biologically varied systems that enhance water quality, control erosion, keep stream flows, sequester carbon, and carry out a residence to at least one 3rd of every threatened and also endangered species.
You are watching: List two environmental functions that wetlands provide
Wetlands room important due to the fact that they:
In the not too distant past, wetlands were pertained to as wastelands. Most human being felt that they were locations to it is in avoided, and it was typical practice to drainpipe them, to fill them or law them together dumping grounds. A study released by the U.S. Fish and also Wildlife company in 1990 revealed a startling fact: much more than fifty percent of the 221 million acre of wetlands the existed in the lower 48 says in the so late 1700s have been destroyed.
Today, we understand that wetlands provide many essential services come the environment and to the public. They offer an important habitat because that fish, waterfowl and also other wildlife, lock purify polluted waters, and they aid check the damaging power that floods and also storms. They also administer a wide selection of recreational avenues such as fishing, hunting, photography, and wildlife observation. Together these and many various other wetland functions and also values described listed below have become an ext widely known, wetlands are progressively seen as abundant and beneficial resources worthy the protection and restoration.
Water Quality: Wetlands plot as organic water purifiers, filtering sediment and absorbing many pollutants in surface waters. In some wetland systems, this cleansing role also boosts the top quality of groundwater supplies.
Reduction of seaside Storm Damage: coastal wetlands assist to blunt the pressure of major storms. Because that example, mangrove forests in south Florida and salt marshes along the Atlantic and also Gulf shores reduce flooding, coastal erosion, and also property damages during major storms.
Flood Control and also Streamflow Maintenance: Wetlands follow me rivers and also streams absorb energy and store water during storms, i m sorry reduces downstream flood damage and lessens the risk of flash floods. The sluggish release the this save water over time can assist keep streams flowing during periods that drought.
Streambank Stabilization and Erosion Control:Wetland vegetation binds the soil on streambanks and riparian wetlands, staying clear of excessive erosion and also sedimentation downstream.

Upland wildlife favor deer, elk and also bears typically use wetlands because that food and also shelter. Wetlands are particularly an essential to numerous migratory bird species. Because that example, wood ducks, mallards, and sandhill cranes winter in flooded bottomland forests and also marshes in the southern U.S., and also prairie potholes provide breeding grounds for over 50% of north American waterfowl.
Fish and also Shellfish Habitat: Freshwater and marine life including trout, striped bass, pike, sunfish, crappie, crab, and shrimp rely on wetlands for food, cover, spawning, and also nursery grounds. Between 60% and 90% that U.S. Advertisement fisheries count on wetlands.
Habitat because that Threatened and Endangered Species: about one-third of every plants and also animals noted as intimidated or endangered varieties in the joined States depend on wetlands for your survival, consisting of whooping cranes, American crocodiles, the dwarf lake iris and several orchid species.
Specialized tree Habitat: almost 7000 plant species live in U.S. Wetlands, plenty of of which have the right to only survive in these wet environments.
Ecosystem Productivity: part wetland types are among the most abundant ecosystems on earth. A stand of cordgrass in a salt marsh can produce more plant material and also store an ext energy per acre than any agricultural crop except grew sugar cane. Nutrients and also plant material purged from part wetland systems during storms administer essential food for plants, fish, and wildlife in estuaries and also other downstream ecosystems.
Recreational Opportunities: countless wetlands save a diversity the plants, animals and water features that administer beautiful places for sightseeing, hiking, fishing, hunting, boating, bird watching, and photography.

Water Supply: part wetlands help carry out clean, plentiful water supplies. Because that example, wetlands in Florida"s Everglades help recharge the Biscayne Aquifer, the sole resource of drink water because that the Miami metropolitan area.
