    How we built this. Forecast engine: the UVAFME forest model, initialized from satellite data (Google AlphaEarth) and the city's street-tree inventory. Climate: downscaled CMIP6 projections (a high-warming pathway). Species risk includes emerald ash borer, hemlock woolly adelgid, beech leaf disease and spotted lanternfly. Replace = trees projected to be stressed or lost by 2050; Plant here = the city's vacant land — a conservative ceiling on where trees could go, not a claim on the land. Trees coexist with development (yards, edges, streets, green stormwater), and one tree per 150 m² leaves room to spare. Dollar figures are conservative estimates (home-value premium, replacement cost, and ecosystem-service value). Built by Raiho Consulting.
