New York City Blockface Tree Counts from 2015 Census

Blockface-level data from the 2015 TreesCount! street tree census organized by NYC Parks & Recreation and volunteers. It provides tree counts and collection status for city blocks, linking to detailed tree-level records. The dataset was last updated in February 2024.

Use Cases

• Analyze tree density by neighborhood using the `trees` count aggregated per `block_id` and `nta_name`.
• Map blockface-level data collection completeness and status using the `block_stat` and `surv_date` fields.
• Join blockface summaries to detailed tree records using `block_id` for species-level urban ecology studies.
• Assess spatial distribution of census effort by correlating `surv_date` with geographic coordinates like `start_lat` and `start_long`.

Strengths

• Data originates from a systematic city-wide census conducted by NYC Parks & Recreation.
• Includes geographic identifiers like `boro_ct`, `nta`, and `zipcode` for multi-level spatial analysis.

Limitations

• Census data is from 2015, representing a snapshot nearly a decade old.
• Sample data and total row count are unavailable, preventing assessment of completeness.
• The relationship between blockface summaries and individual tree records is not described in detail.
