 Most of the track remains in its original location , which is now within the Shapwick Heath biological Site of Special Scientific Interest and National Nature Reserve . Following purchase of land by the National Heritage Memorial Fund , and installation of a water pumping and distribution system along a 500 @-@ metre ( 1 @,@ 600 ft ) section , several hundred metres of the track 's length are now being actively conserved . This method of preserving wetland archaeological remains ( i.e. maintaining a high water table and saturating the site ) is rare . A 500 @-@ metre ( 1 @,@ 600 ft ) section , which lies within the land owned by the Nature Conservancy Council , has been surrounded by a clay bank to prevent drainage into surrounding lower peat fields , and water levels are regularly monitored . The viability of this method is demonstrated by comparing it with the nearby Abbot 's Way , which has not had similar treatment , and which in 1996 was found to have become dewatered and desiccated . Evaluation and maintenance of water levels in the Shapwick Heath Nature Reserve involves the Nature Conservancy Council , the Department for Environment , Food and Rural Affairs , and the Somerset Levels Project .
