Field Name Description Source
ID Unique identification number for each tree. Citizen Pruner
Common Name Common tree name. Citizen Pruner
Scientific Name Scientific tree name. Citizen Pruner
UFORE Species Code UFORE (Urban Forest Effects) urban forest software that analyzes tree pollution removal and emission and calculates quantity and dollar value. The program uses a 4 or 5 digit code by tree species. Citizen Pruner
Native to Local Area Native to local area? Yes or No Citizen Pruner
Address Street address of tree. Citizen Pruner
Location Location of the tree in relation to street address. Citizen Pruner
Borough NYC Borough Citizen Pruner
Pit Tree in a pit? Yes or No Citizen Pruner
Pit Size (ft2) Area of the tree pit in square feet. Citizen Pruner
Pit Condition Conditon of the planted area. Citizen Pruner
Expand Grate Does the iron grate covering the tree pit need to be expanded? Yes or No Citizen Pruner
Tree Condition Tree condition Citizen Pruner
