Because this is a slow process, change in soil and vegetation at any one location from bare sand to a late stage in the succession such as dune heath will take 100s of years. However, because the dunes near the coast are young and mostly become progressively older through time it is possible to use distance as a surrogate for time. As you walk from the strand line inland you will walk from young to old dunes. Aim: The aim of the investigation was to study the factors that affect the vegetation cover, and thus the influence that it has on the Morphology of the Guincho Beach Dune System. First of all, what will be looked at is: how the distance from the sea (i.e. High tide mark) can affect the percentage cover of vegetation in the region studied, and how it varies along a transect line going down the beach. ...read more.

Conclusion

And perhaps the area chosen to study might have been my biggest limitation, as not only did I only study one transect but also the location as well as other factors might have influenced the data.7 Evaluation and Conclusion Overall this investigation didn't show what I guessed, although in the kite diagram it was quite obvious that as one goes further down the transect line the percentage cover of vegetation will increase. This is not show, however, in the results for the spearman's rank. Instead it says that there might be a correlation with the distance from the HTM and the vegetation cover, however the probability is very low. The increase in the vegetation cover was most probably due to the ups and downs of the land, and not so much the distance which it had from the HTM; thus making my hypothesis mistaken. As for the wind speed, although the results do not show this, if I were to repeat this investigation again, using a larger range of transect lines, and if I were to use an anemometer instead of the method I used, then for certain I would probably have gotten better and more correlating results. 1 http://www.kscience.co.uk/as/module5/succession/summary.htm 2 Aerial photo of Guincho, photo was taken from Google earth. 3 http://en.wikipedia.org/wiki/Conservation_areas_of_Portugal 4 Equipment used 5 Calculations for Spearman's rank 6 Kite graph and table 7 Table and graph for Spearman's rank of Wind speed.
