"Arboriculture" (visual definition)

Cf. verbal definitions e.g. "The Arboricultural Association defines arboriculture as the science and practice of the cultivation, establishment and management of amenity trees for the benefit of society. Other organisations may describe it slightly differently, but ultimately the meaning is the same: arboriculture is tree care."
