Shade Audit

Your city promised a million trees. We're counting.

Consumer-facing urban tree canopy accountability — city-level canopy scorecards, equity analysis (rich vs. poor neighborhoods), ecosystem service dollar valuations, "million trees" pledge tracking, heat-death correlation maps, and species-level urban forest profiles, all auto-generated from satellite data and city open data portals.

Niche Explored

Urban tree canopy accountability — tracking city-level tree cover change, equity analysis (income vs. canopy), ecosystem service valuations, and holding city “million trees” pledges accountable using satellite and open data.

Existing Competition

American Forests / Tree Equity Score — treeequityscore.org — interactive map with equity scoring per census block group. Comprehensive but static: doesn’t show change over time, no content/storytelling layer, no accountability tracking of city pledges. Think-tank voice, not consumer media.
Casey Trees (DC) / Tree Report Card — caseytrees.org/treereportcard2024 — annual report card for Washington DC only. Single city, once-a-year. No automation, no national scope.
i-Tree Tools — itreetools.org — USDA Forest Service calculation engine for ecosystem services (air quality, carbon, stormwater). Has an API (api.itreetools.org). Technical tool for arborists, not consumer content.
Canopy (Palo Alto) — canopy.org — local nonprofit, one city, occasional blog posts.
PlanIT Geo — planitgeo.com — B2B SaaS for urban foresters. No consumer presence.
Nature study (Feb 2025) — “The hottest areas in U.S. cities are losing the most greenery” (npj Urban Sustainability) — academic paper, not a content channel.
Brownsville Revival blog — one-off article about tree canopy as political issue. Not a channel.
NO dedicated, regularly-updated, consumer-facing, multi-city urban tree canopy tracking site exists. The gap is enormous.

SEO Analysis

“tree canopy map” — moderate volume, low difficulty
“urban tree equity” — growing term, low competition
“tree canopy coverage by city” — informational queries with no definitive answer site
“million trees [city]” — sporadic searches around news events
“heat island map [city]” — growing searches each summer, peaks in July-August
“tree canopy loss” — strong academic/news presence but no consumer hub
“which city has the most trees” — common curiosity query, no definitive source
Summer heat waves drive massive traffic spikes for heat island / urban cooling content
Every city tree planting announcement drives local search interest

Communities

r/urbanforestry (3K+ members, active)
r/arborists (100K+ members)
r/urbanplanning (400K+ members, tree canopy comes up regularly)
r/dataisbeautiful — tree canopy maps are top posts when they appear
Twitter/X urban forestry community is active and engaged
Landscape architecture + urban planning professional communities

Local journalism — every city has reporters covering tree equity

Image/Graphic Feasibility

Excellent. Satellite imagery before/after comparisons are visually stunning and shareable
Tree canopy maps with heat overlay are inherently beautiful
Equity heatmaps (income vs. canopy) are powerful and viral
Tree species illustrations can be AI-generated effectively
City “report cards” with letter grades are highly shareable
Progress bars for “million trees” pledges are compelling visual elements

Key Stats for the Pitch

Nature study (Feb 2025): Hottest neighborhoods in US cities are losing the MOST greenery — the exact opposite of what should happen
npj Urban Sustainability (2025): Increasing tree canopy lowers urban air temperature by up to 1.5°C
American Forests: Low-income neighborhoods have 40% less tree canopy on average
Portland lost tree canopy from 2014-2020 despite net population growth (University of Oregon study)
Federal Inflation Reduction Act allocated $1.5B+ for urban tree planting — but tracking actual outcomes is nearly impossible
USDA Forest Service: Urban trees provide $18.3 billion/year in ecosystem services in the US alone
100+ US cities have “tree planting pledges” (million trees, 30% canopy by 2040, etc.) — almost none have public accountability dashboards
