Introduction

Investigation Into The Length Of Ammophillia arenaria On North And South Facing Sand Dunes In Broomhill Burrows, Fresh Water West September 2003 1.1- Introduction I will be investigating into if there is a difference of the height of Ammophillia arenaria on north and south facing dunes. A.arenaria is not usually found in inland soil but is abundant on the sand dunes(1). It grows in large masses and its strong, far-creeping roots (sometimes 15-20 meters long) help it to collect water(2). These roots also hold the constantly shifting sand dunes(3) which otherwise would travel inland and can overwhelm farmland and villages. It is often used to stabalise shifting dunes. When one layer of sand is fixed by its roots the grass grows up through the fresh sand drifting on top and repeats the process of fixation, which is important for succession. The rolled leaves are also very long with a thick outer cuticle(4) in order to reduce the rate of transpiration. This allows it to survive on the dunes where water drains quickly(5) and conditions are often warm and windy. On sand dunes (especially yellow dunes which A.arenaria grows on) ...read more.

In field work it is difficult to control all variables but the two sites identical in terms of their, age, size and level of vegetation. In addition to this I also decided to take some abiotic data. I measured light intensity using a light intensity meter at 1 meter off the ground from a random co-ordinate on the grid. Temperature was taken at ground level using a whirling hydrometer. Wind speed was also measured at ground level using an anemometer. Soil samples were taken by pushing a 10cm3 tube into the ground and removing the soil. This was then placed in a polythene bag so none of the moisture was lost before it could be tested. The pH of the soil could also be tested from this sample. All these measures were carried out on both north and south sides of the dune. 3.0 - Summary Table Of The Length Of A.arenaria On North And South Facing Dunes Length (mm) North Facing Side South Facing Side 634 - 691 2 0 692 - 749 4 0 750 - 807 11 1 808 - 865 15 0 866 - 923 21 2 924 - 981 4 0 982 - 1039 3 22 1040 - 1097 0 ...read more.

Conclusion

On the north facing side of the semi-fixed dune the abiotic data and my observations suggest that there was less light available to the organisms living there. This meant that the plants were receiving less energy from the sun to use in respiration and growth. There was also less interspecific competition as few otherplants could At any one time the dominant species will be the plant best adapted to its surroundings. Neither side was directly facing the sea so that should not of be a factor<explain more here> Abstract The aim of the investigation was to investigate the differences in height of A.arenaria on north and south facing dunes. The hypothesis tested was that there would be a statistical difference in the height of the A.arenaria on north and south facing dunes. The investigation was carried out at Broomhill Burrows, Fresh Water West during September 2003. The height of the longest blade of A.arenaria was measured in random locations within a 10x10m grid on the north and south facing sides of a dune. These were then statistically compared using a students 't' test. This showed that there was a statistical difference between the height of A.arenaria on north and south facing dunes at the 5% confidence level. ?? ?? ?? ?? ...read more.
