[Solved] You have been asked to act as the ecological consultant for a minerals company proposing the extraction of sand and gravel from an area of land alongside the River Hertford between Cayton and Flixton. The proposals will require planning permission and the preparation of a formal Environmental Impact Assessment. The client is proposing to create a series of lakes and ponds following completion of the extraction – there is considerable scope for you to advise them of the most appropriate design for the restoration work.
