Transcript of riparian areas
They provide clean water for a variety of human uses, as well as habitat for wildlife and aquatic life.
Today, emphasis on water quality and protecting surface water has shifted to nonpoint source pollution.
Management of riparian areas on farms has been a major focus of nonpoint pollution control efforts.
Livestock grazing riparian areas can cause problems with nonpoint source pollution.
A riparian zone with diverse vegetation can trap 80% to 90% of sediments transported from fields
The trapped sediment, along with the new lush growth helps water infiltration and increases water storage. New roots and leaves shade the soil and conserve water and increase storage. More organic matter is produced and soils become more porous. Organic matter acts like a sponge to hold water and is involved in the formation of soil aggregates that enhance soil porosity.
Flooding and Erosion
Moderate temperatures help in plant growth.
The more plant productivity the greater variety of fruits, nuts, and vegetation.
Shade will help maintain lower water temperatures in the summer months.
The cooler water temperature the higher the DO levels are.
DO's or (Dissolved Oxygen) is important water quality for survival of aquatic organisms.
postive effects of Biodiversity
Biodiversity is great for economic use and tourism for people
also biodiversity makes the riparian more healthy and able to with stand disasters that occur.
It also tends widens the food chain making the riparian area more complex in species connections to each other
increases amounts of food in the area for animals
robust biodiversity has led to the development of drugs that come from plants or microbes. Around half of all drugs on the market in the United States are derived from plants, animals, or microbial organisms.
in other words the more plants, animals, and microbes that exist, the better the chances of finding treatments for a wide range of diseases and conditions.
most ecological systems that humans need to survive also rely on a biologically diverse ecosystem to operate. This is true for purifying water, the recycling of nutrients in soil, and the pollination of flowers, among many other things. It is very difficult for people to properly replicate these intricate ecosystems with man-made alternatives.
Surface water, streams, rivers, ponds, and lakes are some of our most precious natural resources.
Soil in natural riparian areas consists of stratified sediments of varying textures that are subject to intermittent flooding or fluctuating water tables that may reach the surface. The duration of soil wetness depends on the water levels of the adjacent water body.
warm season grasses are much deeper and denser than that of turf grass, they are much more effective in preventing erosion.
Streambank vegetation reduces the risk of erosion. Firstly, root systems of shrubs and trees protect stream banks from erosion by reinforcing and increasing cohesion of the soil, and by providing a protective surface matting.
Naturally vegetated riparian areas can reduce the force height and volume of floodwaters at a particular point along a stream by allowing water to spread out horizontally along the floodway and across the floodplain thereby helping to maintain stable streambanks and protect downstream property
what are riparian areas?
Riparian areas are lands that occur along watercourses and water bodies. Typical examples include flood plains and streambanks. They are distinctly different from surrounding lands because of unique soil and vegetation characteristics that are strongly influenced by the presence of water
