Evaluation of weed maintenance activities on the river Idle

Silsoe College was asked by the Lower Trent Area of the Severn Trent Region of the National Rivers Authority (NRA) to evaluate the current weed maintenance regime on the River Idle, north Nottinghamshire. The study required the assessment of the benefits of regular weed maintenance activities to users of the river and the disbenefits incurred if weed maintenance was not to be carried out.
