Description
Detached residential structures serving one to four families each (includes twins and duplexes).
Structures containing more than four residential units (includes apartment complexes and
row homes). Includes all trees associated with this land use type (e.g., street trees, park-like
lawns, hardscape patios, parking lots).
Downtown commercial districts, malls, strip malls, and shopping plazas. Includes all trees
associated with this land use type (e.g., street trees, park-like lawns, hardscape patios,
parking lots).
Factories, warehouses, and trucking businesses. Includes all trees associated with this land
use type (e.g., street trees, park-like lawns, hardscape patios, parking lots).
Schools, colleges, hospital complexes, religious buildings, and government buildings.
Includes all trees associated with this land use type (e.g., street trees, park-like lawns, hardscape patios, parking lots).
Maintained or landscaped public parks. Includes all trees in or adjacent to a park (i.e., located in hardscape, lawn, or adjacent sidewalks).
Tree is located in a natural park or open space area that has minimal human intervention.
All trees within natural area land use should have site type “natural area/vacant” but not
vice-versa (i.e., trees may have that site type but be located on properties with different land
uses). Natural areas include forests, prairies, woodlands, and other natural or minimally
managed habitats.

Land Use & Site Type
Examples
The following pages contain examples of how to classify urban trees for site type and land use with our protocols,
with examples of photos following. Please see sections 1.1 Land Use and 1.2 Site Type for more information and
examples of those values
*Note that “natural area/vacant” is both a site type and a land use. All trees in “natural area/vacant” land use should
have that same site type. However, the reverse is not necessarily true. Trees on a variety of land uses can have
