Why are coastal wetlands so important?
Coastal wetlands support important benefits—called ecosystem services—that impact our day-to-day lives. They provide clean drinking water, flood protection, recreational opportunities, and more. They also provide important habitat for commercial and recreational fisheries.
What are 3 functions of coastal wetlands?
Some of these services, or functions, include protecting and improving water quality, providing fish and wildlife habitats, storing floodwaters and maintaining surface water flow during dry periods.
Why are the wetlands important?
Wetlands are highly productive and biologically diverse systems that enhance water quality, control erosion, maintain stream flows, sequester carbon, and provide a home to at least one third of all threatened and endangered species.
Why are wetlands important 3 reasons?
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.

Where are coastal wetlands?
Coastal wetland is used broadly here to identify areas where wetland plants inhabit the coastal zone, in either freshwater or saltwater environments of the coastal zone.

What is a wetland quizlet?
a wetland is an area of land that is covered with a shallow layer of water during all or some time of the year. they formed in places where water is trapped in low areas where groundwater seeps to the center.

In which of the following ways can coastal wetlands protect the coast?
Erosion Control: Coastal wetlands can prevent coastline erosion due to their ability to absorb the energy created by ocean currents which would otherwise degrade a shoreline and associated development.
What two kinds of vegetation grow in coastal wetlands?
Plants in a Wetland Plants that are adapted to moist and humid conditions (such as those found in wetlands) are called hydrophytes. These include cattails, water lilies, bulltongue, sedges, tamarisk, and many kinds of rush. Wetland plants are adapted to the saturated conditions that persist for a majority of the year.
Why are wetlands important to the health of the overall environment quizlet?
Wetlands reduce flooding and erosion by absorbing water and then releasing it slowly.
Why is it important to protect wetlands quizlet?
1. flood protection – the holding capacity of wetlands helps control floods and prevents water logging of crops. 2. water quality – wetlands function like filters by removing polluting nutrients and sediments from surface and groundwater.
Why are coastal wetlands important quizlet?
Estuaries and coastal wetlands are important because they spawn/nurse fish and shell-fish, filter out waterborne pollutants, are breeding grounds for waterfowl, and habitat for alligators. Mangrove swamps serve as erosion protection, prevention of hurricane and typhoon damage, entrapment of sediment, and nursery.
Why are wetlands important to the environment quizlet?
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.
What are 3 economic benefits of a wetland?
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.
Why is coastal vegetation important?
The native vegetation in coastal areas plays an important role in stabilising the surface against wind erosion and provides habitat for wildlife. Coastal dunes provide a buffer against coastal hazards such as wind erosion, wave overtopping and tidal inundation during storm events.
How Do wetlands protect water quality?
Wetlands can improve water quality by removing pollutants from surface waters. Three pollutant removal processes provided by wetlands are particularly important: sediment trapping, nutrient removal and chemical detoxification.
How do wetlands help climate change?
Wetlands are Carbon Sinks Wetlands capture CO₂ from the atmosphere, making them nature's own solution to the climate emergency. In fact, they store more carbon than any other ecosystem on Earth, and peatlands alone store twice as much as all the world's forests.
Which of the following are important functions of wetlands quizlet?
Water Purification, flood protection, shoreline stabilization, groundwater recharge and streamflow maintenance, and fish and wildlife habitat.
What characteristics of wetlands are important for humans quizlet?
What characteristics of wetlands are important for humans? (Mark all that apply.) They help slow waters down, decreasing the severity of flooding and erosion. Their plant growth stabilizes the soil. They hold back surface runoff, allowing time for infiltration into aquifers.
What benefits does wetlands provide to the environment?
Wetlands have been used for centuries as grazing for domestic stock, and as a source of reeds used for thatching, hut construction and basket weaving. They provide opportunities for fishing, hunting and to observe wildlife, especially birds.
What is coastal vegetation?
4.2. 2(i) Coastal vegetation. Intact coastal vegetation, including mangroves, salt marshes, seagrasses, macroalgae, and coastal strand and dunes, buffers shores and retains sediments from the effects of erosive processes, such as tides, waves, and storms.
How do coastal plants survive?
Plants that grow along the coast are very tolerant of the winds and salt and sand loaded ocean spray. Many species are succulent, storing salty water in their leaves. The leaves are often light colored or grey green to reflect sunlight and reduce desiccation.
How do wetlands prevent erosion?
Vegetated wetlands along the shores of lakes and rivers can protect against erosion caused by waves along the shorelines during floods and storms. Wetland plants are important because they can absorb much of the energy of the surface waters and bind soil and deposited sediments in their dense root systems.
How do wetlands provide natural flood control?
Wetlands slow the flow of water, allowing it to replenish the ground water supply that most plants and many people depend on. By slowing the water during floods, wetlands reduce flood damage in areas downstream and around them.
How do wetlands improve water quality?
Wetlands help maintain good water quality or improve degraded waters in several ways: Nutrient removal and retention, Processing of chemical and organic materials, and. Reduction of the sediment load of water.
How do wetlands reduce flooding and erosion?
As flood waters recede, the water is released slowly from the wetland soils. By holding back some of the flood waters and slowing the rate that water re-enters the stream channel, wetlands can reduce the severity of downstream flooding and erosion.
What is wetland and its benefits?
Wetlands act as “nature's kidneys” by removing polluting nutrients and sediments from surface and groundwater. By protecting water quality, wetlands keep our lakes, streams, and groundwater healthy and are important to the integrity of aquatic ecosystems.
How do sand dunes prevent erosion?
How Do Sand Dunes Prevent Coastal Erosion? Sand dunes are a natural force against coastal erosion. They protect the coast against high waves and storms, and they adapt naturally to the wind and water in a way that disperses energy and protects the coastline.
