* To investigate and compare species diversity in an aquatic and terrestrial habitat

Activities:

Random Sampling (quadrat)

* On land, a quadrat measuring 2.5m in size was randomly thrown at 8m intervals. The varying species in the quadrant was observed and recorded. This process was then repeated four times.

Pond Sampling

* A net was glided over the surface of an undisturbed area in the swamp. After skimming the surface the contents were emptied into bucket of clean water and were observed and recorded. This was then repeated twice. The net was then dipped into the middle layer of an undisturbed area in the swamp. After the passing of the net, the contents were emptied into a bucket of clean water and were observed and recorded. This was then repeated twice. Lastly, the net was dipped into the bottom layer of an undisturbed area in the swamp....
