Arborsculpture 

Creating sculptures out of living trees by encouraging them to grow in certain ways that are both aesthetically pleasing and functional.

I have seen some beautiful examples of arborsculpture.

Arborsculpture 

An instant method of tree shaping done by bending mature trees to achieve a woven form. Basically a form of 3D pleaching. The method uses tree whips approximately 2-3 meters long. These are bent and woven into the design shape and held by metal bars until the trees new growth rings form a cast.

Richard Reames coined the word Arborsculpture in 1995 to rename the art form of tree shaping.
