Most cities manage their urban forests on gut instinct and aging data, and on this episode of Rooted in Innovation, presented by Tree Staple, host Dionisio Roman talks with Josh Behounek, a 25-year consulting arborist at Davey Tree Expert Company, about how that's changing. Josh explains how Davey's partnership with tech company Greehill uses LiDAR scanning and AI to build a full digital twin of a city's tree canopy, why leaf area index and percent dieback have become the strongest predictors of a tree's health, and how a two-year rescan cycle is finally giving city foresters a closed feedback loop on their removal and pruning decisions. The conversation also covers what it takes to build a 20-year urban forest master plan that survives a change in city administration, with real examples from Pittsburgh, Knoxville, Louisville, and Atlanta. If you manage green infrastructure for a city or just want to understand the strategy behind the trees lining your streets, this episode lays it out.
