Area has been identified as one which can be developed as a New Nature Reserve, by Enfield BC who have produced an action plan to enhance land include a ditch and pond as well as the bankside habitat. This will include control of Floating Pennywort and other invasives as well as enhancing the morphological features of the bank. Area is currently grazed by a couple of horse and contains little ecological value - area is boarded by the backloops of the river Lea which are reported to support a population of water voles.
