# Biodiversity of Ethiopian Forest

Extracts from this document...

Introduction

Biodiversity of Menagesha Forest Aim -To assess the level of diversity in different parts of the Menagesha National Forest, by using the Simpsons Diversity Index we can compare the diversity levels to each other. Controlling variables -The size of the area being measured is very crucial because if this number varies the test will not be a fair one. In this case an area of 20 meters squared was measured. Another control was only measuring plants taller the one meter. This let us make the research more narrow and accurate. If we had to measure all the plants in the area not only would it have taken a lot of man power but also a lot more expertise. Hypothesis -The diversity of the forest will alter in different parts of the forest. The older the area being assessed the more diverse the species will be. ...read more.

In the young plantation there are 6 different plants but with one species of plant that is dominating the area in number. ...read more.

Conclusion

Another thing I noticed while at the forest was the fact that the older the forest the bigger the difference in the positioning of the canopies. The results we got through this research were fairly accurate and depicted the results that are to be expected, except for Natural Forest B. This variation in our results shows that the research could be improved to give even more accurate results. One thing that could be done is measuring a bigger area for each type of forest. Another thing that has to be done is more research so the names for all the species are known. Also when we counted the plants, if there was a group of them together it was counted as one, instead of doing this I think if the size of the area it occupies would be a better measure. If there were more people I think it would have been better if we did more than one set of data for each type of forest so as to get more accurate results. ?? ?? ?? ?? 1 ...read more.

For the percent cover, in of the 5 different quadrats, there were no consistencies within the data. For quadrat one, populous was the most commonly occurring specie, with 16.2 percent cover of the whole quadrat. For quadrat 2, populous was the most common specie, and showed 22 percent cover of the sample.
