Tree sitting is a form of civil disobedience in which a protester sits in a tree, usually on a small platform built for the purpose, to protect it from being cut down (i.e. speculating that this will not be done because it would be very dangerous for the protester). Supporters provide them with food and other necessary supplies.
Sitters have blocked logging of ancient forests for months at a time, and have in fact convinced logging companies not to cut trees in some areas. Julia Butterfly Hill is probably the most famous tree-sitter; she protested deforestation by sitting in a 180-foot, 600-year-old Redwood tree (which she named Luna) for 738 days.
