Have you heard of the Te Urewaera Act of 2014? It's a pretty cool law from the Māori that recognized a New Zealand forest as its own legal entity.
"The key principles of the new Act are:
- Te Urewera ceases to be a national park and is vested in itself as its own legal entity; and
- Te Urewera will own itself in perpetuity with the Board to speak as its voice to provide governance and management in accordance with the principles of the Act"
