What is a key method for restoring a degraded wetland?

A key method for restoring a degraded wetland is the reestablishment of native vegetation and the restoration of natural hydrology. Wetlands rely on specific plant species that are adapted to their unique environments; these plants play a crucial role in maintaining water quality, providing habitat for wildlife, and stabilizing soil. By reintroducing native species, the ecosystem can begin to function more effectively, as these plants are better suited to the local conditions compared to non-native species.

Restoring natural hydrology is equally important because many wetlands have been altered due to drainage or development. By returning water flow patterns to their natural state, wetlands can regain their ability to filter pollutants, manage floodwaters, and provide critical habitat for various species.

The other options do not address the holistic approach needed for effective wetland restoration. For instance, implementing strict hunting regulations, constructing artificial lakes, or allowing unrestricted development overlooks the essential ecological processes and plant communities that define healthy wetlands. These actions can often lead to further degradation or lack the necessary connection to the natural dynamics of wetland ecosystems. In contrast, focusing on native vegetation and hydrology directly aims to restore the foundational elements that support the entire wetland environment.
