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.
