Name Type Details Description
CREATOR type: String
width: 40
precision: 0
Name of the editor who created the record.
INSPECTR type: String
width: 40
precision: 0
Name of the tree inspector.
SPECIES type: String
width: 30
precision: 0
Common name of the species of the current tree.
DIAMETER type: Single
width: 4
precision: 6
Tree diameter in inches taken at approximately 4.5 feet above ground (DBH). If the diameter point falls on a swelling in the trunk it is customary to measure below the swelling at the point where the diameter is smallest. Note: an average diameter should be calculated for trees with multiple trunks (see the Trunks field); an online calculator for multi-stemmed trees may be found at https://www.treetec.net.au/TPZ_SRZ_DBH_calculator.php.
TRUNKS type: SmallInteger
width: 2
precision: 5
Number of tree trunks (see note at Diameter about using the number of trunks to calculate an average tree diameter).
NOTES type: String
width: 500
precision: 0
Miscellaneous notes.
SITETYPE type: String
width: 20
precision: 0
Designates whether the site is currently occupied by a tree (Tree) or stump (Stump), is an empty planting site (Planting Site), or has been paved over or is otherwise empty and no longer available for planting (Retired). Note: this field typically supersedes any conflicting data within the record; for example, a record designated as a “Planting Site” would indicate that any values for Diameter and Trunks were no longer valid.
PLANTDATE type: Date
width: 8
precision: 0
Date that a tree was last planted at this site.
REMOVALDATE type: Date
width: 8
precision: 0
Date that a tree was last removed from this site.
SPECIESSHORT type: String
width: 50
precision: 0
Genus of the current tree species (see Species).
TREEID type: String
width: 50
precision: 0
Unique identifier for the record.
OVERHEADWIRES type: SmallInteger
width: 2
precision: 5
Designates the presence of above-ground utility wires in the area of tree canopy growth at the site.
CULTIVAR type: String
width: 50
precision: 0
Cultivated variety of the current tree species (see Species).
STREETNUMBER type: SmallInteger
width: 2
precision: 5
Number of the street address closest to the site.
STREETNAME type: String
width: 40
precision: 0
Name of the street for the address closest to the site.
MEMTREE type: String
width: 1
precision: 0
Designates whether the current tree was planted in memoriam.
LOCATION type: String
width: 50
precision: 0
Designates whether the site is located along a street (Street Tree), beyond the back edge of a sidewalk in a front yard or other area not immediately adjacent to a street (Back of Sidewalk), in a park or other open space (Park Tree, Cemetery Tree, Golf Course), or on the grounds of a public school or other municipal building (Public School, City Building).
OWNERSHIP type: String
width: 50
precision: 0
Designates the ownership of the tax parcel on which the site falls.
ADACOMPLIANT type: String
width: 1
precision: 0
Designates whether the site is ADA compliant, for instance whether the site has the minimum required sidewalk width of 4 feet.
TREEGRATEACTIONREQ type: SmallInteger
width: 2
precision: 5
This field is used to record if the metal tree grate surrounding the tree needs to be reset or removed. When the tree grows, it can get girdled by the tree grate.
BAREROOT type: String
width: 3
precision: 0
Designates whether the last tree was planted as a bare-root tree.
TREEWELLCOVER type: String
width: 25
precision: 0
The type of cover, if any that is over the tree well. The two values are Tree Grate or Flexi-Pave.
STRUCTURALSOIL type: String
width: 5
precision: 0
Indicates if the tree was planted in structural soil.
TREEWELLLENGTH type: Double
width: 8
precision: 38
The length of the tree well.
TREEWELLWIDTH type: Double
width: 8
precision: 38
The width of the tree well.
ABUTSOPENAREA type: String
width: 5
precision: 0
Indicates if the tree abuts an open space or if the tree well is the only open area around the tree.
EXPOSEDROOTFLARE type: String
width: 5
precision: 0
Indicates if the root flare of the tree is visible.
