Wetlands serve as vital transition zones that support high levels of biodiversity by providing essential food and habitat for a wide array of species.1

Support for Waterfowl and Wildlife

Wetlands, particularly marshes and shallow lakes, are highly productive environments that offer several critical benefits for waterfowl and other wildlife:
* Food Resources: These areas produce diverse plant life and invertebrate populations that serve as rich food sources. Periodic fluctuations in water levels, such as those caused by temporary droughts, can stimulate plant growth, which provides abundant seeds and prey when the area is reflooded.12
* Breeding and Shelter: The presence of extensive shoreline provides isolation for breeding pairs, cover from predators, and protection from harsh winds.2
* Ecological Connectivity: Wetlands act as crucial stopover points for migratory species, allowing them to exploit seasonal productivity fluctuations across different regions.32

Support for Fish

Wetlands function as productive nurseries and feeding grounds for fish. Their role in nutrient cycling and the export of organic materials helps sustain aquatic food webs. Furthermore, the complex structure of wetland vegetation offers refuge for juvenile fish, protecting them from predators while they grow.12
