Is something wrong with your trees? How do you keep your forest healthy? How might climate change affect your trees? When something goes wrong people tend to look for specific causal agents such as bark beetles or root disease. But tree health problems often arise from factors such as climate, soils, exposure, and/or changes as trees grow older, perhaps interacting with insects or diseases. Attend this class to learn about diagnostic methods and tools to help you understand and observe possible changes in forest health and threats. After decades of diagnosing tree problems for clientele, your local Extension Forester has much to share to help you assess and manage your forest and tree health into the future.
