DC Tree Summit seeks to increase capital's canopy Washington Examiner:
How to increase the capital's tree canopy will be the subject of a tree summit later this month.
The March 25 summit is being organized by Casey Trees, a Washington-based not-for-profit committed to restoring, enhancing and protecting the tree canopy of the nation's Capital.
Increasing tree canopy coverage has a number of environmental benefits. Trees not only provide shade, helping keep cities cooler and saving on air conditioning costs, they also help control runoff and improve air quality, among other benefits.
