Arboriculture is the science that includes the selection, propagation, care and selective felling of perennial and woody plants, such as trees and shrubs, the study of their growth and that includes traditional practices.

Its objective is to manage individual feet, generally located in gardens or urban areas, to increase their health, longevity, resistance to pathogens and improve their aesthetic characteristics. However, it is an autonomous science, independent of forest science or silviculture, that manages, maintains, exploits and conserves natural forests. It is considered that arboriculture is to forestry what gardening is to agriculture.

From this concept, urban forestry is derived, which is a specialized branch of forestry whose purpose is the cultivation and management of trees with a view to taking advantage of the current and potential contribution that they can make to the well-being of the urban population, both from the physiological, sociological and economic point of view,[1]​ where efforts should be focused on an urban tree management program and thus address the challenges of climate change.

In the case of Chile, the need for Urban Arborization programs has already been addressed with programs such as Urban Parks (MINVU), Community Green Areas (MMA), Arborization Program (CONAF), among other public-private initiatives.

For the Ministry of Housing and Urban Planning (MINVU), Green Infrastructure is one of the strategic axes that promotes nature-based solutions and recognizes the fundamental role of ecosystem services in human well-being, where the planning of urban trees is being addressed mainly from a technical approach and proposal of an Urban Tree Management Program for the Tarapacá Region.
