Luna is a coast redwood tree, also known as the 'Stafford Giant.' The tree is between 600 and 1000 years old and lives in an old growth forest--Headwatfornia. The tree was named by Earth First!, who built a small tree-sit platform from salvaged wood 180 feet above the forest floor. They chose the Latin word for "moon" to commemorate the event. Julia Butterfly Hill lived in Luna for 738 days.
