The stream at Fletchers Thorns was straightened in Victorian times to quickly drain that part of the forest. This canalisation created unseen problems at the time. Through HLS funding the original meanders were identified and reinstated with the straightened section being in filled and returned back to Forest. The stream is now back to its original course and interacting naturally with its floodplain.
In 2015 an independent study was undertaken by the River Restoration Centre and Jonathan Cox Associates to survey a selection of restored wetland sites from 2004 to monitor their success post restoration. See the survey below:
