18.72.030   Definitions.
   A.   The following definitions in addition to the definitions in Chapter 18.03 will apply to this chapter:
      1.   Caliper: A measurement of diameter taken on a circular tree trunk at twenty-four (24) inches above the highest natural grade at the tree trunk base; for a noncircular specimen, use the average of the shortest and longest measurements of diameter twenty-four (24) inches above the highest natural grade at the tree trunk base and for a multi-trunked specimen, use the sum of the measurements of diameter of the two (2) largest trunks twenty-four (24) inches above the highest natural grade at the tree's multi-trunk base.
      2.   Damaged: The condition of a viable inventoried plant previously identified on the approved native plant preservation plan as a preserved-in-place, salvage and transplant, replacement, or supplemental plant, which has little chance of survival in a healthy and attractive manner due to injury, infestation, or disease as confirmed by the monitor or the county.
      3.   Destroyed or destruction: The condition of an existing plant after it has been demolished or eliminated as shown on the approved native plant preservation plan.
      4.   Development: Any permitted or nonpermitted human alteration to land and its vegetation, soil, geology, drainage, hydrology and surface features; changing the appearance and character of land; and including but not limited to the acts of grubbing, clearing, and grading of land, and placing improvements on the land such as buildings, structures, signs, paving, vegetation, and outdoor use areas.
      5.   Drip line: For cacti, an area around the plant that overlays the mature root system: For trees and shrubs, an area under the undisturbed canopy of the tree or shrub.
      6.   Endangered Species Act Of 1973: A federal law enacted for the protection of endangered and threatened species in the continental United States, also referred to in this chapter as "Endangered Species Act."
      7.   Mitigation: The replacement of a specimen(s), an inventoried plant(s) rated medium to high viability, that is destroyed or removed from the site as shown on the approved plant preservation plan with a plant(s) of the same genus and species from off site in good physical condition with a high rating for health, age, and form.
      8.   Native plant preservation plan: A plan for the preservation of protected native plants prepared and submitted in conformance with this chapter, also referred to as "preservation plan."
      9.   Native plant preservation manual: The standards and procedures for implementing the requirements of Chapter 18.72, Native Plant Preservation, also referred to as "preservation manual" or "manual."
      10.   Plant community: A biologic grouping of vegetation frequently found under natural conditions due to their common soils, moisture, climate and orientation requirements; also means a plant association.
      11.   Preservation-in-place: No disturbance of one or more plants and the associated understory plants, or no disturbance of a plant community as in the set-aside method: Preservation-in-place is promoted by site planning and design that retains existing plant genus and species in their current location, grade, and configuration and promotes their future health and growth.
      12.   Property owner, developer, applicant: The person(s) or legal entity that has fee title to the site or a legal right to control development of the site, or a designated representative on the property owner's behalf.
      13.   Protected native plant: Any living plant on the protected native plants list found in Table 18.72.040-1 Protected Native Plants: For the purpose of this chapter, also referred to as "native plant(s)."
      14.   Regulated riparian habitat areas: Also referred to as "riparian habitat" shall mean riparian habitat areas identified on the county's riparian habitat maps as established by Article X of the "Pima County Floodplain and Erosion Hazard Management Ordinance."
      15.   Riparian regulations: When used will mean Article X of the "Pima County Floodplain and Erosion Hazard Management Ordinance," entitled "Watercourse and Riparian Habitat Protection and Mitigation Requirements" which includes approved hydroriparian, mesoriparian, and xeroriparian plant and seed lists.
      16.   Safeguarded plants: All species listed in the "highly safeguarded" category of the Arizona native plant law, A.R.S: § 3-901 et seq.; also referred to as "safeguarded species."
      17.   Set-aside: A method of plant preservation identified in this chapter; shall also mean the permanent protection of land and all vegetation in an undisturbed state within an area designated as a set-aside area.
      18.   Site: Refers to a single lot or a combination of contiguous lots (or parcels), or a leased area on a lot that meets the minimum zoning standards of the applicable zone.
      19.   Specimen or specimen plant: A single inventoried plant (native plant or safeguarded plant) rated medium to high viability.
      20.   Transplantability: The relative ability of a native plant to be successfully transplanted.
      21.   Viable plant, also a viable inventoried plant: An inventoried native plant in good physical condition with a medium or high rating for health, age and form, but which may or may not meet the "transplantability" standards of this chapter.
