Boxwood blight is a disease affecting plants in the family Buxaceae including boxwoods (Buxus), Pachysandra, and Sarcococca plants. First detected in the U.S. in 2011, it has since been found in multiple states and provinces from the East Coast to the West Coast. Boxwood blight has now been confirmed on boxwood nursery stock in New Hampshire. New Hampshire nurseries, landscapers, town officials and residents responsible for boxwood plantings should learn the symptoms associated with boxwood blight. Watch for black lesions on stems, "zonate" brown spots on leaves leading to chlorosis, and leaf drop. If boxwood blight is suspected on recently purchased boxwoods, or plants in proximity to recently purchased boxwoods, please contact the Division and collect a sample for analysis by the UNH Plant Diagnostic Lab.

The National Park Service (NPS) has finalized a long-term strategy to reduce the impacts and threats from invasive plants and to restore native plant communities and historic landscapes for 15 national park areas in D.C., Maryland, Virginia and West Virginia. The Invasive Plant Management Plan will guide park staff in standardizing and streamlining their treatment of non-native invasive plants. The plan will also help the NPS identify areas with the most urgent needs in order to address the most immediate threats to park resources. Each of the 15 area parks will develop an annual non-native invasive plant treatment strategy that is based on science, is cost effective, and poses the least amount of risk to people and park resources.
