An investigation of a wetland ecosystem: Cley Marshes in Norfolk.

Extracts from this document...

Introduction

An investigation of a wetland ecosystem: Cley Marshes in the Norfolk. How the ecosystem is managed The Cley marshes are exceptionally well managed. The marsh is extremely well managed because it is a very rare habitat, where species breed each year. Each of the four habitats within the ecosystem are being managed, on of these are the reed beds. The reed beds are cut every 2/3 years on a rotational cycle to vary the age of the reeds. This enables the biodiversity to greaten. Furthermore, silt is collected around the base of the reeds and dries out, which allows other plants to root; this is not good quality for the wildlife so they are separated. ...read more.

Middle

The land is grazed by tenant farmers, who also bring income to the land. Managing the drainage ditches plays a significant role in the ecosystem. The drainage ditches are dredged to keep plants out and sediment is removed to permit the water to flow freely. The fertilisers used for surrounding the agriculture is washed into the ditches, which causes and enhance in algae growth. This influences problems, as the algae can become poisonous. In addition, the level of sodium in the water is also monitored to make sure that slat is not entering the ecosystem, as the plants are halophobic. Last of all, the scrapes are managed by monitoring the level of water. Y it is managed This ecosystem is rightly managed because it is a unique and rare ecosystem. ...read more.

Conclusion

If however, there were no birds this would mean the ecosystem is not working in order. The area is also highly successful in attracting a large number of tourists each year, in particular bird watchers. Bird watchers flood in from all over the world, this results in a valuable income for the local village, which only had a population of 350. in Norfolk 50% of the population are over 60 so they do not generate much. Most of the local income is gained through locally running bed and breakfast, hotels, shops and pubs - particularly as farming creates not much of an income in the county. Human activities - tourists/visitors - litter, pollution, erosion, scaring away the birds. ...read more.
