Learning about urban forestry. We've started with a reading list from a Tree Tenders' group in Philadelphia — the “greene Country Towne which will never be burnt, and always be wholesome” (– Wm. Penn). We're also looking at the wider northeastern part of the continent, always interested in urban forestry in other cities around the world, and in taking lessons from research and observations in the woods and forests outside of cities as well. Help us to compile useful and relevant readings.
