Unlisted Wetlands in Sindhudurg
Unlisted wetlands are shallow wetlands sites in Sindhudurg, having a rich habitat which are not mentioned in the Environment department Wetland Brief Documentation list or on the Wetland Atlas of Maharashtra. Shallow wetland habitats can be some of the most diverse, productive, and highly used habitats on a property. They may offer food and cover for a variety of wildlife species, but often target wetland dependent wildlife, specifically migratory waterfowl.
Shallow wetlands typically require some management, but the goals and desired outcomes for the wetland and property may determine the intensity of that management. Shallow wetlands should be less than 18 inches deep, but should vary from that maximum depth to nearly dry or even mudflat. Depth should also vary annually, depending on the goals for the wetland, but should strive to have suitable water levels for wetland dependent wildlife at critical times of the year. For instance, it is important to maintain water in most wetlands throughout spring.
Most shallow wetlands should go through a dry period in most years in order to maximize productivity for wildlife. We refer to these wetlands as “seasonal” because they are usually not flooded for the entire year.
Moist Soil Management
Shallow wetlands will often be most beneficial when managed for “moist-soil plants”. These species grow on mudflats as water levels are drawn down through slow draining or passive evaporation. These are primarily annual grasses and shrubs that produce an abundance of seeds and underground tubers that will provide food and cover for a variety of wildlife. Moist-soil seeds are a very healthy food source for wildlife, with high levels of carbohydrates and essential nutrients and amino acids, and some seeds are even high in protein. Moist-soil management involves the slow de-watering or drawing down of shallow wetlands in the late spring or summer to expose mudflats and encourage moist-soil plant growth. Once seeds have matured, wetlands can be re-flooded to provide habitat for wetland dependent wildlife. Moist-soil management typically relies on being able to impound water behind a low levee or berm, or by de-watering depressions in wetlands. All managed wetlands should include a water control structure that can be opened and closed to allow water level manipulation.
