1. A study was made of 3 ponds on Clifton Campus to determine the effects of management,
particularly dredging, would have on these ponds. The study looked at the biodiversity
effects of management on aquatic invertebrates and plants, and on terrestrial animals and
plants. The study also looked at the variations in biodiversity between the three ponds,
particularly in relation to aeration. Best practice for future management was also studied.
2. Ponds show rapid recovery from disturbance such as dredging, and are rapidly re-colonised
by plant and invertebrate species. Aeration appears to have little effect on the biodiversity
of ponds.
3. Best management practice for ponds is to make as small alterations at possible. When
dealing with a complex of ponds work should be staggered to ensure that disturbed ponds
can re-establish from adjacent ponds.
