Introduction

NOWER WOOD FIELD STUDY Aim Our aim was to study two different areas of woodland that have been cut down at different times, and to study the diversity and the abundance in the ground plants in each of them. The two coppices are close to each other. The two coppices are 7(young) and 30(old) years old. Our main aim here is to check the diversity and abundance between the 2 coppices, plus comparing the species. Hypothesis I think that there will be more bio-diversity in the young coppice. I think this because the old coppice will have had more time to develop, and there will be a developed canopy, which will let through only enough light for the shade tolerant plants. The young coppice, however, will have a spotted canopy, and a much larger variation of plant life, as the light amounts from place to place will vary. Factors affecting Abundance/Diversity There are a many factors that that we want to monitor, as these are the factors that will affect how the plants have grown. These will all affect the plant's life in some way, whether it turns to be a large or small factor. Light Light is possibly the most important part of plant growth and survival; and light is measured in LUX. We use the environmental meter to measure light. ...read more.

We used the species key to identify the species; this had a certain amount of plant species on it. When we took readings from the quadrat, we first identified a particular species, and then counted the number of squares it was in; this is what gave us our results Auger The auger is basically a large drill that we used to drill into the soil, in order to get the samples of soil we needed for the results. With the auger, we drilled into the ground. Then, once we'd removed the auger from the ground, we'd take the soil samples from the bottom of the auger, at the lowest point on the ground. The soil samples were needed for the results in soil moisture, pH, and soil type tests. Soil pH Kit This consists of 5 items to help us get our results from the soil; these included the following * Spatula * Distilled H20 * Indicator * BaSO4 * Test Tube We rubbed the soil in our hands first, mixed with the water; this was to clean it to a certain extent. From that we could tell the type of soil, aswell as the moisture, however to get the acidity we had to do the following. We put it in the test tube, and added BaSO4 and indicator before mixing it with a spatula. ...read more.

Conclusion

In my hypothesis I stated that basically there would be a wider variety of species in the young coppice rather than the old coppice. This happened because of the reasons I stated in my results sections, so it hasn't come as a surprise. However, although this was always likely to happen it doesn't mean that our results are perfect, or that we have done the experiment completely correct. There are reasons for this; we don't have the time to check every single area of each coppice so our results won't necessarily be perfect, however when we did our 5 samples, we used a random number table to generate our positioning, yet with trees and other groups in the way, and possibly not walking straight it was easy to get sidetracked slightly. When searching through the coppice, human error may enter into the process, as it possible that certain species could have been missed, especially in the old coppice with separate layers of plants. Human error could actually be present at many parts of our experiment, and it is just something that we have to get on with, hopefully using machines like the environmental meter to give us more accurate results. Results could always vary due to the weather, of course we do measure temperature and humidity, but as we are only there one day, we wouldn't be able to see how results varied on different, however it is unlikely there is a major difference, unless there has been a heat wave, or a giant thunderstorm. ...read more.

    AIR & WATER MOVEMENTS (WIND) Both are important in dispersing seeds and spores so they determine the distribution of many species. Intensity of the movement may also influence shape and survival of organisms, especially plants where transpiration rates are affected.

    This would dramatically affect the results. Of course I will take all of this information in to consideration when I'm building my experiment with a mirror (or sheet of glass) and I'm not so interested in a dynamic collection of data showing how condensation collects on the surface, and this

    Limiting factors are also responsible for the geography of plant distribution (University of Arizona, 1998). The combination of two hydrogen atoms with one oxygen atom forms the most common substance on earth, water. The combination of these two atoms plays a major role in all the processes of physical life.

    Clay helps to hold the mud together to avoid it being washed into the river or wetland. Clay is not well draining and could be responsible for the way mangrove mud appears to be wet even when the tide has long since gone out.

It is in the gametophyte form of mosses where the potential for land development in some ecological scenarios may be limited. The gametophyte does not posses a true root and vascular system (xylem or phloem)
