Endorian trees, more commonly referred to as Redwood trees, were a species of ancient tree that naturally grew on the Forest Moon of Endor. These redwood trees existed in large quantities and were utilized by the Ewoks as a construction material to build and reinforce their lofted homes.
The first appearance of Redwood trees was in the film Star Wars: Episode VI Return of the Jedi. Filming for the movie took place in Redwood National Park, and the production's temporary name was Blue Harvest.
