Managing existing ponds
Managing existing ponds entails occasional dredging, limiting excessive plant growth and cutting back overhanging trees. However, before considering any management, observe the pond through the whole course of a year, noting factors such as water levels and areas of flooding, and their relationship with plant and animal types. A survey can be carried out to decide upon the best course of action. Look carefully at the existing habitats in the pond and ensure that part of all existing features are kept, e.g. do not remove all the leaves or fallen logs. Ask questions like: If I dredge out this part of the pond, which plant and animal species will suffer? If unsure rethink the aims of the management work. Your Local Wildlife Trust. may be have some records on the pond, or be able to give assistance with the survey work.
The Working season for management of wetlands should only be carried out in the period from September to November. This avoids the breeding and hibernating seasons, minimising disturbance to wildlife. Work should be limited to defined zones, with areas managed in rotation over a period of years, i.e. divide the pond into sections and each year clear some sections of the pond (bank and deep water).
Be particularly careful with wetlands in semi-natural countryside (old-meadows, ancient woodlands, heathland or marshes), since these are likely to support uncommon species. Check for signs of life in the pond before thinking about action.
