In late September some Green Ash were still leafed out when the temperatures plummeted. We observed many trees holding dead leaves over winter. To compound the problem, we've received little precipitation in the fall and little snow cover over the winter. This spring was hard on our trees too. In April the temperatures were really mild until the end of the month when the temperatures dipped going into the beginning of May. Many Aspen poplar that were leafed out during this time period, suffered a bit of frost damage. I would agree that it is abiotic.<BR><BR>June is Recreation & Parks Month.
