South Lincolnshire Natural Burial Ground at Sutterton is regulated by the Association of Natural Burial Grounds.
The association, run by The Natural Death Centre, sets the standards for the growing number of green and environmentally friendly cemeteries in the UK.
Bob Lowrie at the Sutterton site says a lot of energy is used in cremation, and burial in a nondegradable coffin at six feet “doesn’t allow nature to do its job”.
He says: “With natural burials we only go down four feet and at that depth, particularly with the trees, the corpse degrades naturally and completely and in fact feeds the trees, so you are actually recycling yourself.
“What could be nicer? There aren’t rows of headstones and the spacing we have is a lot more than you would get in a conventional cemetery.
“I know it’s only seven years old but this has to be one of the most attractive arboretums in the county.”
