From the list below, which is a benefit of wetlands to the environment?
Submenu Show This information was modified from Chapter 2 of At Home with Wetlands: A Landowner's Guide. Wetlands perform many ecological functions. Knowledge and understanding about the complexities wetland ecosystems represent is still developing. Wetland ecologists have already documented the following environmental benefits wetlands provide:
Wetlands also provide habitat for fish and wildlife, including endangered species. Not all wetlands provide all of these benefits, and how your particular wetland works depends on its location and type. Some of the values of wetlands are yours and yours alone. No one else can say what the open space means to you and your family. You determine the benefit to your quality of life and how you value a wetland's beauty. Wetland benefits depend on healthAs amazing as wetlands are and contribute to the environment, they do have their limits. A partially filled or otherwise damaged wetland can only partially meet its potential for flood control, shoreline stabilization, or groundwater recharge. A degraded wetland can lose its capacity to remove excess sediments, nutrients, and other pollutants. It can also lose its habitat value for fish and wildlife. Wetlands may have tremendous capacities to provide environmental benefits but they are not indestructible. If people want wetlands to continue to perform their ecological functions then everyone must do their part to protect them. Below is a summary of how wetlands perform their complicated functions, along with a brief explanation of how these functions support humans and other species.

Which of the following is a benefit provided by wetlands?Far from being useless, disease-ridden places, wetlands provide values that no other ecosystem can. These include natural water quality improvement, flood protection, shoreline erosion control, opportunities for recreation and aesthetic appreciation and natural products for our use at no cost.
Which is the largest benefit of wetlands?One of the most valuable benefits of wetlands is their ability to store flood waters. Maintaining only 15% of the land area of a watershed in wetlands can reduce flood- ing peaks by as much as 60%.
