The Study of a Psammosere Succession.

Extracts from this document...

Introduction

The Study of a Psammosere Succession By Peter Wilby Introduction I have decided to study a Psammosere for my A2 geography project, and research into specific factors that affect the dune system. I will investigate the reasons for the change in the dune's appearance and how these factors have made the dunes form in this particular way. The reason for why I chose to study a Psammosere is that I wanted to expand on the knowledge I already had on a dune system. I have come up with various hypotheses of the sand dune formation, which I hope to prove or disprove. These are: * There is a distinct sequence of dune succession; * The amount of vegetation cover and the number of species both increase the further inland you are; * Moisture content and organic matter increases the further inland you are; * Wind speeds decrease further inland; * Human activity directly changes and damages the dune, and can have an effect on the dune shape. The project was carried out on Oxwich Bay, which is in the Gower Peninsula, South Wales. ...read more.

The wind speeds were taken at each sample point and the average over a period of 5 seconds was noted, which meant that the results were much more accurate, and if any result anomalies did crop up then averaging out the result would make it more accurate. The amount of vegetation and different species This was measured with the use of a quadrat. The quadrat was thrown randomly onto the ground around the sample point, so I did not take any bias results. I then counted how many squares were covered with vegetation to give me a number out of 100, which would give me a percentage. Along with how much vegetation there was I would carefully comb through the vegetation around me to count how many different species there were. The amount of moisture and organic matter in the soil This was done by bagging a small sample of soil at every sample point on the first transect. I only took samples at these points because the soil sample would not differ very much at all between each transect. I then took them back to the geography department and weighed the samples. ...read more.
