        The green zone along a stream ecosystem is called a riparian area
        and has several unique properties. Riparian zones have the capacity to
        buffer rivers and other waters from runoff from agricultural, urban, or
        other areas. Healthy riparian zones can absorb sediments, chemical
        nutrients, and other substances contained in runoff.
         Riparian areas provide all the components needed for a wildlife
        habitat including food, water, and cover. Diversity of organisms living
        in these wetland areas is very high. A riparian habitat includes three
        areas depending on the influence of water. The aquatic area refers to
        the area that is the stream channel or pond. The organisms that live in
        this area must be adapted to a wet lifestyle. Not far from the banks of
        the water is an area referred to as the riparian area which are
        organisms that require a moist habitat. Many plants require their roots
        to be moist. A transition area between a riparian area and upland cover
        is called an area of influence. Moisture decreases as you move away from
        the water.
