American Forests' Tree Equity Score combines tree canopy coverage, surface temperature, income, employment, race, age, and health data to identify where trees are needed most. Scores range from 0 to 100, and areas below 60 are priority for investment.

Equity Indicators
These factors show how tree canopy gaps overlap with social and environmental vulnerabilities.
1930s Redlining
0.0%
Federal redlining maps from the 1930s didn't cover this area. Only about 239 cities were mapped, mostly major metros.
Environmental Justice
50.0%
of neighborhoods are classified as overburdened by the White House's Climate & Economic Justice Screening Tool, meaning they face outsized pollution, poverty, or health risks. Trees help, but they're not the whole fix.
Heat Island Effect
+1.4°F
hotter than surrounding areas on average. Pavement absorbs heat, trees block it. That's the whole pitch.
People in the Data
19,661
people live across the 12 Census block groups we analyzed. That's who these numbers represent.

We have Tree Equity data but this city is missing free tree programs, local nurseries, native species info, and community partners. Your local knowledge turns a data page into something people can actually use.

Data only
We know Westbrook, ME's canopy coverage to the decimal. The "where do I get a free tree" part? Still digging through PDFs from 2011.
