The 2024 Phenology Calendar adorns the wall with beautiful nature photography and average observation dates for many natural phenomena. Rooted in the Leopold family’s passion for the study of phenology and curated by Aldo Leopold Foundation Senior Fellow Stan Temple, the calendar offers reminders for seasonal events happening in your backyard throughout the year. 2024 marks the 75th anniversary of Leopold’s seminal work, A Sand County Almanac. To recognize and celebrate this conservation classic, the 2024 Phenology Calendar will feature selections from the book and Leopold’s Shack Journals.

New features in 2024:

• Larger wall calendar size – 12.625” x 9.125”
• Thicker paper with glossier images
• Additional secular and religious holidays
• Additional space to write in appointments and nature observations
• Sidebar narratives featuring entries from the recently transcribed Shack Journals
