According to the Green Burial Council, "Natural burial grounds, cemeteries, and preserves all seek to bury without impediment. That means no embalming, no liners or vaults, and using biodegradable containers, whether caskets, shrouds or nothing at all. These cemeteries are operated by a variety of owners: municipal governments, religious groups, individuals, nonprofits, for-profits, and others. Often these burial grounds are designated natural because they may not be directly affiliated with or in partnership with a land trust or other conservation entity; but they most likely are committed to following conservation best practices nonetheless. Natural burial cemeteries strive to provide rich experiences for families and friends amidst careful restoration and maintenance of the land and its inhabitants, both above and below ground."
