Julia Butterfly Hill

Julia Lorraine Hill (known as Julia "Butterfly" Hill, born February 18, 1974) is an American environmental activist and tax redirection advocate.

She is best known for having lived in a 180-foot (55 m)-tall, roughly 1500-year-old California redwood tree for 738 days between December 10, 1997, and December 18, 1999. Hill lived in the tree, affectionately known as Luna, to prevent Pacific Lumber Company loggers from cutting it down.
