Soil Erosion
FISH BEING AFFECTED BY SHORELINE EROSIONErosion is the process that moves soil from one location to another by wind, water or other natural action. A natural process, or is it always? Unfortunately, shoreline erosion is too often accelerated by human action. In my original FWA outline I determined to focus on how agriculture contributed to this erosion process. My original statement was "Cattle need to be restricted from the banks of water. Cattle cause soil erosion problems by destroying shoreline vegetation that in turn affects fish population", however, as a result of further research, I am now concluding "Humans need to be restricted in their use of natural water banks. Humans cause soil erosion problems by destroying shoreline vegetation that in turn affects fish population.One of the most attractive features of our lakes and rivers is the shoreline. In addition to the view and recreational aspects, the shorelines also provide essential habitat for numerous plants, fish and animals. This natural habitat can be affected by excessive wave action caused by watercraft travelling too close to the shoreline, land owners who remove trees, rocks and other vegetation, and by farming operations providing access to shor
Over time, bank erosion will result in large amounts of sediment entering the water and reducing its useable capacity. Its loss also reduces the soil's capacity to accept, store, and release water for plant growth. RECREATIONThere are numerous ways within the freshwater aquatic environment in which the effects of recreational boating may be felt, and there are a number of different kinds of effects. 21)ˇ Let wind and water do their work ˇ ˇ Perhaps help them by over-irrigating (see 14. In the aquatic environment there are bottom sediment, bulk water column, surface microlayer and shoreline habitat compartments. Because organic matter is rich in nitrogen, phosphorus, and other nutrients, loss of soil organic matter reduces a soil's fertility and its capacity to produce crops. This results from better access to water, increased palatability, and lack of harmful bacteria and parasites. The construction of boat houses, boat docks, and boat launches all contribute. A vegetative buffer of trees, shrubs, and grasses extending 30 - 50 metres from the waterline provides water quality protection. 4)ˇ ˇ extreme case: Sanmexia dam, Yellow River, China: filled up in 4 yearsˇ ˇ it was rehabilitated, by digging tunnels into the base of the dam and flushing out the sediment --- a major expenseLoss of soil organic matter is usually related to the loss of topsoil through erosion. When over abundant, some plants - such as algae, provide a poor environment for fish. Erosion will remove the topsoil first. Many of these actions could have easily be prevented by simple knowledge about shoreline erosion and by using simple action to prevent significant soil erosion such as leaving a buffer strip on the shoreline of the water to prevent unnecessary erosion from occurring Increased sediment in our water is effecting the fish population by killing fish eggs.
