The 2015 tree census was the third decadal street tree census and largest citizen science initiative in NYC Parks’ history. Data collection ran from May 2015 to October 2016 and the results of the census show that there are 666,134 trees planted along NYC's streets. The data collected as part of the census represents a snapshot in time of trees under NYC Parks' jurisdiction.

The census data formed the basis of our operational database, the Forestry Management System (ForMS) which is used daily by our foresters and other staff for inventory and asset management. To learn more about the data collected and managed in ForMS, please refer to this user guide:

Record of Forestry tree points for NYC Parks & Recreation.

Tree Points and Planting Spaces form the basis of ForMS 2.0’s data inventory and are the core entities that all Service Requests, Inspections, and Work Orders are associated to. The system has built-in rules to ensure that every Tree Point has a Planting Space and each Planting Space can have no more than one active Tree Point at a given time. Locations that have had one tree removed and another tree replanted will appear in ForMS 2.0 as a single Planting Space associated with one retired Tree Point (that has a removal Work Order) and one active Tree Point.

This dataset can be joined to the Forestry Planting Spaces dataset by joining PlantingSpaceGlobalID from Forestry Tree Points to GLOBALID from Forestry Planting Spaces.

Street tree data from the TreesCount! 2015 Street Tree Census, conducted by volunteers and staff organized by NYC Parks & Recreation and partner organizations. Tree data collected includes tree species, diameter and perception of health. Accompanying blockface data is available indicating status of data collection and data release citywide.

Citywide street tree data from the 2005 Street Tree Census, conducted partly by volunteers organized by NYC Parks & Recreation. Trees were inventoried by address, and were collected from 2005-2006. Data collected includes tree species, diameter, condition.

Citywide street tree data from the 1995 Street Tree Census, conducted by volunteers organized by NYC Parks & Recreation. Trees were inventoried by address, and were collected from 1995-1996. Data collected includes tree species, diameter, condition.

Ecological benefits from street trees. Indicates the physical impact and monetary value of that impact for each tree. These values were calculated using i-Tree https://www.itreetools.org/

Blockface data from the TreesCount! 2015 Street Tree Census, conducted by volunteers and staff organized by NYC Parks & Recreation and partner organizations. Blockface data includes tree counts and data collection status by block. Accompanying street tree data is available, indicating tree-level details such as tree species, size and other characteristics.

Risk Assessments are sub-components of Inspection records where Type = Level 2. Trees are inspected in accordance with Parks' Tree Risk Management program. For a given defect identified on a tree, 3 rating variables are selected to arrive at a Total Rating. Because multiple defects can be noted on a tree, multiple Risk Assessment records can be related to one Inspection.

City blocks surveyed for tree planting by NYC Parks foresters.

The polygons in this dataset show mapped forest restoration planting polygons. These polygons depict areas where invasive plants were removed and native trees and/or shrubs were planted under the purview of NYC Parks? Natural Resources Group as part of the MillionTreesNYC initiative on property under the jurisdiction of NYC Parks. Spring plantings occur between January 1 and June 30, while Fall plantings occur between July 1 and December 31 of any year. Older restoration polygons were mapped via heads-up digitizing while the location of newer polygons have been collected using a high-accuracy GPS device.

Tree Contract Work Details contains information related to work performed on specific tree work contracts. This dataset can be joined to the Forestry Work Orders dataset (https://data.cityofnewyork.us/Environment/Forestry-Work-Orders/bdjm-n7q4) by joining work_order_id from Tree Contract Work Details to OBJECTID from Forestry Work Orders. There are many work_order_ids per single contract_number. Not all work orders in Forestry Work Orders are represented in this dataset because it is only used to track work on specific contracts.

This data tracks the blocks that have been planted through NYC Parks’ street tree block planting program, a major component of the MillionTreesNYC initiative. When a block planting is completed for specific street segment, all available and appropriate locations for street tree installation have been planted. This dataset is based on the Citywide Street Centerline data.

Blockface data from the TreesCount! 2015 Street Tree Census, conducted by volunteers and staff organized by NYC Parks & Recreation and partner organizations. Blockface data includes tree counts and data collection status by block.
