A couple of farmers from Calvados are protecting their land for the next 99 years. Pascale and Christian Cedra have already planted 230 trees from 77 different varieties.
The couple signed a Real Environmental Obligation (ORE) which obliges everyone to respect the biodiversity of a land for a given period. Nothing, not even the death of the owner or the sale of the land, can lift this provision. The Danub' association can come once a year to ensure that nothing, soil, trees or biodiversity in general, has been harmed on this plot.
