Introduction

On 2nd November, we went to have a field trip in Sam A Chung. The aim of our field trip was to assess the impact of the environmental stresses on the pattern of biodiversity present within an ecosystem. We were allowed to use a modified transect method to assess the diversity of plants on a hillside and in a valley.

We were divided into small groups, each group contains four students, to do this project. We recorded all plants that are in contact with the 10m transect line in hillside and valley to give a distribution of species along a line of change in topography.

Equipment

A tape-measure, clips, 10m length of rope and a metal stake.

Procedure

1. The metal stake was driven in at the start point and was attached the flag with our group number (no. 27).

2. One end of the rope was fixed to the stake.

3. The rope was stretched as straight as possible uphill along the path to its full length of 10m at 2ft above the ground and the other end was fixed to the second stake.

4. The tape
