About
Presents essential information collected during the 2015 New York City Tree Census. This valuable resource documents the urban forest, offering insights into tree location, health status, and physical characteristics. The data is a cleaned and processed version of the original census, focusing on crucial attributes for analysis concerning ecology and urban planning. This dataset helps users know the trees of NYC.
Columns
The dataset includes 20 columns detailing various aspects of the trees recorded:
tree_id: The unique identification number for each tree.tree_dbh: Diameter of the tree at breast height (DBH). The mean diameter is approximately 11.3, with a maximum recorded diameter of 450.stump_diam: Diameter measurement if the tree is a stump. The majority of records show a stump diameter between 0.00 and 2.80.curb_loc: Indicates whether the tree is located OnCurb (96% most common) or OffsetFromCurb (4%).status: The current condition of the tree, primarily Alive (95%), Stump (3%), or Other.health: An assessment of the tree's health, predominantly Good (82%), followed by Fair (14%).spc_latin: The Latin scientific name for the species. The most common species is Platanus x acerifolia (13%). There are 133 unique species recorded.steward: Level of stewardship, with 76% having None recorded.guards: Presence or type of guards, mostly None (88%).sidewalk: Indicates if the sidewalk is damaged by the tree's roots (Damage: 27% or NoDamage: 73%).problems: A text field detailing identified issues, with 67% having None recorded, followed by Stones (14%).root_stone: Boolean flag indicating root damage caused by stones (20% True).root_grate: Boolean flag indicating root damage caused by grates (1% True).root_other: Boolean flag indicating other root issues (4% True).trunk_wire: Boolean flag indicating wires near the trunk (2% True).trnk_light: Boolean flag indicating lights on the trunk (0% True).trnk_other: Boolean flag indicating other trunk issues (5% True).brch_light: Boolean flag indicating lights on the branches (9% True).brch_shoe: Boolean flag indicating shoes on the branches (0% True).brch_other: Boolean flag indicating other branch issues (4% True).
Distribution
The data file is provided as
tree_census_processed.csv and has a size of approximately 70.84 MB. The dataset contains 20 distinct columns. The total number of valid records across key columns is approximately 684,000.Usage
This data is ideal for environmental research, urban forestry analysis, and data visualization projects. Potential applications include:
- Mapping the distribution and density of different tree species across NYC boroughs.
- Analysing correlations between physical features (DBH, status) and urban stressors (sidewalk damage, root issues).
- Studying the overall health and biodiversity of New York City’s urban canopy.
- Aiding municipal planning for future tree care and planting initiatives.
Coverage
The scope of the data covers the street trees surveyed across New York City during the 2015 census, which was conducted by NYC Parks and Recreation staff, Trees Count! program staff, and hundreds of volunteers. The time range is explicitly 2015. Geographic scope is limited to NYC. The expected update frequency for this specific census data is Never.
