In spring, pink-and-white flowers bloom on a crabapple. In summer, a garter snake slithers through tall grass. A squirrel buries acorns amid fallen oak and maple leaves in the fall. In winter, a spruce stands tall and green against the snow. North America is full of plants and animals that survive and thrive during every season. In North American Field Guides, learn about hundreds of mammals, snakes, deciduous trees, and coniferous plants and discover how to identify them in the wild. Aligned to Common Core standards and correlated to state standards. Field Guides is an imprint of Abdo Reference, a division of ABDO.
