Earth Almanac presents the greatest hits of North American nature. Structured around phenology, the study of seasonal patterns in nature, these day-by-day descriptions offer insight into activities and connections throughout the natural world. Beginning with the Winter Solstice in December, Earth Almanac highlights a wide range of natural history, including mammals, birds, fish, reptiles, insects, intertidal and marine life, trees, plants, fungi, environmental activists, and more, all the while revealing the ebb and flow of nature across the planet. Each season features more than 90 entries, and sidebars throughout provide calls to environmental action, citizen science opportunities, and details on special dates or holidays. It makes an excellent gift to celebrate the fiftieth anniversary of Earth Day (April 22, 2020).
