A New Way to Plant Urban Trees | Sustainable Cities Collective:
At the 2010 GreenBuild, Peter MacDonagh, the Kestler Design Group, James Urban, FASLA, Urban Trees + Soils, and Peter Schaudt, FASLA, Hoerr Schaudt Landscape Architects, argued that without new tree planting techniques that use healthy loam soils, major “one million” urban tree planting campaigns will fail, wasting lots of money in the process. MacDonagh said “urban forestry is broken. We need to remake with a different approach.”
