Artificial slope consist of a mixture of huge rocks and concrete. Only few ferns can live in the gaps between the stones. There are a number of lichens on the surface of the slope as they can grow in a adverse condition which has not much nutrients and anchorage. On the surface of the rocks, it is barren rock, which occurs primary succession, it only support mosses and lichens growth. When they grow, the organic matter breaks up the rocks into smaller particles.
In this investigation, both slopes face west.
Procedure:
- Set a slope for observation and investigation
- Put belt transect at every 2 meters
- Start to measure:
- Light intensity, by using a light meter
- Wind speed, by using a anemometer
- Temperature and humidity, by using a theromhygrometer
- 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
Discussion
The types of plants on the natural slope are more than that on the artificial slope. 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.
