´╗┐Hong Kong Taoist Association The Yuen Yuen Institute No.2 Secondary School Biology Field Study 5A Eugenia Chapman (3) Date: 2012/3/30 Title: Biodiversity on an artificial slope is lower than that on a natural slope. Objective: To invest how the abiotic factors effect the biodiversity on a slope. Hypothesis: Plants usually grow on soil. Theory/ Background information: Natural slopes consist of soil, stones and sands. Not only mosses and lichens live on the surface of it, some bigger plants which get anchorage by grabbing tightly of the soil in order to live on the slope. ...read more.


Set a slope for observation and investigation 2. Put belt transect at every 2 meters 3. Start to measure: 1. Light intensity, by using a light meter 2. Wind speed, by using a anemometer 3. Temperature and humidity, by using a theromhygrometer 4. Soil temperature, by using a soil thermometer 4. Count the types and numbers of plant. Results The abiotic factors of both slopes are similar. Therefore, it doesn?t affect the diversion of plants. Tables Natural slope Quadrats 1 2 3 average Number of species 52 79 78 69 Type of species 7 11 11 9.6 Abiotic Humidity (%) ...read more.

Also, the number of plants in natural slope is greater than that on the artificial slope. For example, the percentage of mosses= number of quadrats with mosses x100% Total number of quadrats = 6 x100% 6 = 100% As the nature of natural slope is more suitable for most the plants while the nature of artificial slope is only suitable for mosses, lichens and plants that can be able to grow in adverse conditions. Conclusion Biodiversity on an artificial slope is lower than that on a natural slope. ...read more.
