Installation art, also known as site-specific art, is a form of art that is designed to be sited in a particular location. A 'tree' as part of installation art could refer to an artwork that incorporates or interacts with a natural tree, using it as a canvas or as an integral part of the sculpture. This can range from temporary installations that are meant to interact with the natural elements and the public's interaction with them, to more permanent works that integrate the tree into the surrounding environment or use it as a metaphor or symbol.
