How do wetlands help the environment?

Wetlands cover a small portion of the planet, but their carbon capturing abilities pack a big punch. They can store 50 times more carbon than rain forests, helping to keep the heat-trapping gas that contributes to climate change out of the atmosphere. Wetlands strain matter that contains carbon from the water such as leaves and animal waste. This natural debris is buried by the water and sediment in the wetlands, locking them away. Another advantage is that wetlands grow quickly and are sturdy, meaning they have long lifespans of sucking carbon from the atmosphere.

What is enhancement in a wetland?

(1999) define enhancement as "the modification of specific structural features of an existing wetland to increase one or more functions based on management objectives, typically done by modifying site elevations or the proportion of open water. Although this term implies gain or improvement, a positive change in one wetland function may negatively affect other wetland functions." Lewis (1989) also states that enhancement may also be the alteration of a site to produce conditions that did not previously exist in order to accentuate one or more values of a site. For example, increasing the area of deep water by excavating parts of an emergent wetland may provide more duck habitat (the desired wetland value), but may decrease foraging and cover habitat for young fish.

What is restoration in aquatic ecosystems?

In its 1992 report, Restoration of Aquatic Ecosystems, the National Research Council defined restoration as the "return of an ecosystem to a close approximation of its condition prior to disturbance." The concept of restoration is further clarified by defining many types of restoration-related activities. These activities, such as creation, reallocation and enhancement, are similar to restoration, but differ in some way from the process of renewing native ecosystems to sites where they once existed.

Can wetlands be destroyed?

Under Section 404 of the Clean Water Act, wetlands may be legally destroyed, but their loss must be compensated for by the restoration, creation, or enhancement of other wetlands. This strategy should result in "no net loss" of wetlands.
