Learn about the science of phenology, the study of biological events and how they are related to the development of insects. Phenology can be used to predict the timing of the development of pests like squash bug and Japanese beetles, which helps to stay ahead of them. Aldo Leopold tracked phenological events at The Shack for many years, as did his daughter Nina, and these data are being used today to track differences in timing of events caused by climate change. Presented by Lisa Johnson, Dane County Extension Horticulture Educator. Registration through Rotary Botanical Gardens is required by May 10. Presented via Zoom.
