To investigate the effect of trampling on the frequency of creeping moss - Plan

Extracts from this document...

Introduction

Aim: To investigate the effect of trampling on the frequency of creeping moss Hypothesis: As you move away from the footpath the frequency of creeping moss increases. Scientific name: Pseudoscleropodium purum Justification of hypothesis: As the distance from the path increases, the frequency of creeping moss increases. This is because people tread on this area and therefore make the abundance of creeping moss lower. Box Hill had "1 million visits a year" Emma Peasland, senior tutor, FSC, 24/01/07 (personal communication). It has been around and popular for over 20 years. This means the footpath has been trampled on by a possible 200 million people. If the soil has been trampled on by a possible 200 million people then the footpath is likely to be compressed and the roots of the creeping moss are forced to be of low height and therefore be weak and unstable. Because they are unstable, they will easily be ripped out of their roots. "Soils that are deep, well-drained, and have desirable texture and structure are suitable for the production of most garden or landscape plants. Deep soils can hold more plant nutrients and water than can shallow soils with similar textures. Depth of soil and its capacity for nutrients and water frequently determine the yield from a crop, particularly annual crops that are grown with little or no irrigation. ...read more.

It is a quick reliable way to measure the pH of the soil. This measures the acidity and alkalinity from pH1 to pH14. A thermometer is also needed to measure my other variable. This will measure from 0o to 30o . I will be using this because it is accurate. I will also use 30 pots to take my samples with. This has a maximum capacity of 0.1dm3. I will use a soil pin to measure the soil depth of the soil due to trampling. This soil pin has a maximum length of 0.25m. I will use this because it is not time consuming. Statistical tests: I will be using Spearman's Rank Correlation. I will use this because it shows relationship between the 2 sides. It will show me that as the x factor increase/decreases, the y factor increases/decreases. Method: 1.) Starting from the trampled side lay out your tape measure using your thumb and forefinger and pull the tape measure out of its socket for 12.5m. Once you have done that, return to the tape container and hold out the tape in front of you holding one side of the tape with your thumb and the other side with your 4 fingers, making sure at all times you are walking on the side of the tape measure that you are not going to experiment on. ...read more.

Conclusion

Instead it is just cars moving that will come every once in a while. There is a risk of serious injury be it that you come into contact with one of these vehicles. To control this you must stop, look and listen to any vehicles that maybe be approaching. This will give you the awareness you need to safely cross the road. Slipping on the mud is also a hazard, and since it is on a hill it is even more risky as it is easy to just run down the hill carelessly and slip. To avoid this you will need to bring shoes that have maximum friction and take small fragile steps on not be running. There are also poisonous plants that if come in contact with your skin can potentially kill you if not treated within 45 days. The plant is called wild parsnip. The outcome of touching this will be a disease called photo-phyto-toxic-dermatitis. To prevent this from happening you will have to wear gloves at all times making sure not to touch it or make contact with it in any way. Another hazard is the cold weather and a potential outcome of this if not wearing heavy and insulated clothes are frost bites. ?? ?? ?? ??

This is a good plan on the whole with clear justification for choice of apparatus and method described in detail. Variables could be more fully discussed, however.
