The guidelines for a green or natural burial typically include the following:
“Once a green burial has been completed, the surface of every grave is, after allowing some time for grave settling, planted with locally indigenous plant materials, using a combination of groundcover, shrubs and trees. These plantings will normally be done according to a pre-established planting plan designed to optimize the creation, enhancement and integration of the interment area into the greater local eco-system.”
