Right Tree, Right Place: PG&E and Trees

So it is still dry and breezy.  This fire season in January has me thinking of urban trees again. Here is guidance from PG&E's perspective re: planting distance from power lines, based on mature size of tree. "Proper tree and site selection provide trouble-free beauty and pleasure for years to come."

Friends of the Urban Forest has a lot of great resources for happy trees in San Francisco. Much of the info applies to more developed areas of Marin. Of course there's more to consider than power lines such as neighborly relationships
