Come learn about the care and maintenance of your backyard trees by attending the Pennsbury Land Trust's free presentation on Thursday, March 19, at 7 p.m. in the Pennsbury Township building. The trust has invited tree expert Jason Lubar to share information with local residents on how to care for backyard trees that may have suffered from storm damage or disease, what to do to protect trees and keep them healthy. Lubar  is an associate director of urban forestry, Morris Arboretum, University of Pennsylvania, a board-certified master arborist, and has been a popular consultant on regional radio talk shows and in regional press.
