habitat creation | wetland management
All watercourses should be ranked by their relative importance. Some species such as the kingfisher are indicative of healthy watercourses as are other less obvious species such as liverworts and mosses.
As well as being important habitats in their own right watercourses provide important links both on and off the urban environment. For example, Otters use small streams and even ditches - Otters have now entered the Thames in Oxfordshire, so will move into Berkshire very soon with continued measures. The management of the edges and banks of watercourses should take into account this potential traffic! With the retention of areas of cover, old trees and, in appropriate places, the creation of artificial otter holts, bird and bat boxes.
Most ponds have been created to provide water for livestock or through extraction of gravel, stone or clay. A pond is a temporary landscape feature and naturally becomes filled with dead plant matter and silt. Left for long enough it will become a marsh and eventually dry out completely. Ponds provide valuable habitat for amphibians and many invertebrates and birds.
