Sorry! The 2020 Calendar has sold out.
The 2020 Phenology Calendar adorns the wall with beautiful nature photography and shares average observation dates for many natural phenomena. The calendar is rooted in the Leopold family’s passion for the study of phenology, and monthly sidebars feature explanations of how “Weather and Climate” influence the timing of season events, this year’s calendar theme. Curated by Aldo Leopold Foundation Senior Fellow Stan Temple, the sidebars help explain the seasonal events happening in your backyard and the calendar offers reminders for what you might expect to observe nearly every day of the year.
