Long Island Oak Wilt Symposium

The purpose of this symposium was to gather expertise from the Midwest and Mid-Atlantic regions to assist Long Island in moving from panic to thoughtful and effective action as we begin to deal with oak wilt. We hope to provide nurserymen, landscapers, arborists, agencies, town governments, utility managers, gardeners — all who love oak trees — with an informed perspective on this topic.

Oak wilt, a vascular wilt disease caused by the insect-vectored fungus Ceratocystis fagacearum , was detected in several places in Suffolk County and one site in Brooklyn and Canandaigua in 2016. The extent of the problem, and what this will mean for Long Island, is still under investigation. Cornell University, Central Pine Barrens Joint Planning and Policy Commission, Cornell Cooperative Extension of Suffolk County, and the New York State Department of Environmental Conservation have partnered to develop this free educational program to aid in information sharing and help advance monitoring and management of this potentially devastating disease that could broadly impact the region’s predominant tree species.

The symposium was held On October 25, 2917. Watch it below.
