How Plants Can Clean Stagnant Areas in Swamp Land
Swampland or wetlands are important natural settings that offer many benefits to humans and another biota. Unbalanced wetlands stink. The water and soil may be stagnant which is a sign that the habitat is out of balance. Wetland plants play a huge role in keeping a wetland or swamp balanced. The better balanced a swamp, the more benefits it provides to the aquatic and terrestrial life found in and around the swamp. How does that process work?
How do plants clean the stagnant areas in swamplands?
Plants perform several jobs in wetlands. The first job is that they trap sediments contained in the water. The sediments may be organic, such as dead leaves, or they may also be pollutants such as oil. By trapping sediments, plants bring nutrients to the soil and also remove contaminants from the water. In the case of a sewage spill, the plants remove the sewage from the water by trapping it and then consuming it. Even if the sun dries up sewage, the plants still remove it from the wetland leaving behind clean soil and cleaner water.
Different types of wetland plants perform various types of functions. When a wetland begins to smell like rotten eggs, what has happened is that the oxygen in the soil has been used up by bacteria. The job of fungi and bacteria in a wetland is to break down biotic materials such as dead plants. If there is not enough oxygen, then the biotic materials will begin to break down by chemical methods. Ammonia is on such chemical that breaks down biotic material and also can smell like rotten eggs.
Plants play a role in keeping the soil aerated. Emergent plants such as cattails have a hollow stem. Air can transport down the stem to feed the roots and aerate the soil. Emergent plants, those that live partially submerged due to flooding and tidal actions, also need oxygen delivered to their roots. Hollow stems work well for that process. By being able to adapt to a semi-aquatic environment, emergent plants can break down toxins or pollutants, such as sewer, cleaning the swamp in the process. Illegal dumping of sewage can also cause a wetland to smell. Even as sun or wind dries up sewage, the plants continue to break it down into usable nutrients.
Two basic ways plant clean stagnant swamp areas. The first is to trap the toxins. The second is to provide oxygen to the soil so that the bacteria and fungi can also help to break down the soil. The role that the plants play is directly related to their design. Designs such as hollow stems enable plants to overcome their semi-aquatic habitat and perform benefits that enable other organisms within the swamp to also flourish. The result is that stagnant waters become clean, and the wetland remains in a state of balanced equilibrium. Other benefits that emergent plants provide to a wetland is flood protection and purification of groundwater. Dries up sewage dries up sewage.
