The practice of shaping living trees has several names. Practitioners may have their own name for their techniques, so a standard name for the various practices has not emerged.[1] Richard Reames calls the practice "arborsculpture";[2][82][83] Dan Ladd calls his work "tree sculpture";[5] Nirandr Boonnetr's work is called "living furniture";[6] Christopher Cattle calls his works "grown up furniture" and "grown stools";[7] while Peter Cook and Becky Northey call their work "Pooktre".[84][85]
