For the purposes of this Regulation, the following definitions are adopted:
01. Environment: System constituted by the different natural elements that comprise it and their interactions and interrelationships with human beings.
02. Girdling (Anillado): Procedure consisting of the cutting of a circular section in the bark of the tree in order to interrupt the natural flow of nutrients and cause the slow death of the specimen.
03. Tree: Woody plant, of 6 meters in height or less (medium or low stature), or more than 6 meters in height (tall stature), that branches above half of its total height.
04. Urban Trees (Arbolado Urbano): Set of plants of the species corresponding to the biotypes: tree, shrub, palm, or tree fern, located on urban land.
05. Arborization: Set of activities required for the adequate planting, management of urban trees, improvement of scenic beauty, and regulation of ambient temperature through natural shade.
06. Shrub: Woody plant (at least in its lower parts), of 6 meters in height or less, that branches below half of its total height.
07. Urban Area: the territorial scope of development of a population center.
08. Pest and disease control: Management activities whose purpose is to prevent the increase of populations of living beings that use a plant or some of its parts as part of their life cycle or as habitat, above levels that limit the adequate development and growth of the plant or may cause its death.
09. Species diversity or biodiversity: is the variety and variability among living organisms and the ecological complexes in which they occur, comprising:
Genetic diversity: the genetic variation within species, both between geographically separated populations and between individuals within a single population.
Species and population diversity: all the species and populations on the planet, including bacteria and protists as well as the species of the multicellular kingdoms.
Community and ecosystem-level diversity: The different biological communities and their associations with the physical environment ("the ecosystem").
Landscape diversity: referring to the variability of landscapes produced by ecosystems or their alteration in a given area.
10. Species: an individual that is morphologically, physiologically, or biochemically distinct from other individuals. Individuals that are capable of interbreeding currently or potentially giving rise to fertile offspring, and that are reproductively isolated from other groups; where gene flow occurs naturally.
11. Species with reduced populations: a species that is likely to become an endangered species in the foreseeable future, in all or part of its distribution areas, if the factors causing its numerical decline or the degradation of its habitats continue to occur; or that are rare because they are usually located in geographically limited areas or habitats, or are very dispersed in more extensive distribution areas, and are in real or potential possibility of being subject to a decline and possible danger of extinction or the extinction thereof.
12. Endangered species: one that, due to its scarcity or some other factor of its particular biology, is seriously threatened with disappearing from the country, and whose survival is unlikely if the causal factors of its disappearance (among others deforestation, introduction of exotic species, pollution) continue to act upon it.
13. Endemic species: a species whose natural area of dispersion is restricted exclusively to the national territory or to a portion thereof.
14. Exotic species: a species whose natural area of dispersion does not correspond to the national territory and is found in the country as a result of voluntary or involuntary human activities.
15. Native species: a species whose natural area of dispersion includes the national territory, even if it can be found outside of it.
16. Stem (Fuste): The woody element of the tree (trunk) that constitutes its main structure.
17. Wetland (Humedal): Ecosystem dependent on aquatic regimes, natural or artificial, permanent or temporary, lentic or lotic, fresh, brackish, or salty.
18. The Municipality: This is the abbreviated citation for the Municipality of Belén.
19. Spring (Manantial): surface outcrop of water of underground origin occurring along fractures or changes in lithology in places where the topographic surface cuts the water table.
20. Management (Manejo): Set of technical activities that guarantee the adequate development, growth, and appearance of a plant on urban land.
21. Arborization map (Mapa de arborización): The plan or set of plans in which the position of the areas to be reserved for environmental uses and services and tree improvement is accurately indicated.
22. Biological diversity improvement: Any activity aimed at improving the structural and functional characteristics of the diversity of a given area, for conservation and preservation purposes.
23. Urban Planning: the continuous and integral process of analysis and formulation of plans and regulations on urban development, aimed at ensuring the safety, health, comfort, and well-being of the community.
24. Planting (Plantación): Set of technical activities required for the adequate placement of plants on urban land.
25. Pruning (Poda): Management activity whose purpose is to control and guide the development of some of the parts of a plant or to remove dead parts from it.
26. Natural resource: Any element of biotic or abiotic nature that is exploited, whether or not it is commercial.
27. Reforestation: process of planting trees aimed at the restoration of natural environments and ecosystems, with the purpose of obtaining the environmental services of biodiversity conservation, improvement of air quality, and increase of water infiltration zones, among others.
28. Revegetation (Revegetalización): Reestablishment of vegetation cover using various biotypes, from herbaceous and shrubby to climbing plants and trees.
29. Felling (Tala): Activity involving cutting in any section of the stem (fuste) that can lead to the death of a plant, regardless of its height and its regeneration capacity.
30. Transplant or relocation: Management activity whose purpose is to move a plant from one site to another.
31. Urbanization: is the subdivision (fraccionamiento) and development of a plot of land for urban purposes, through the opening of streets and provision of services.
32. Zoning: is the division of a territorial circumscription into use zones, for the purpose of its rational development.
