Once there stood a giant fir tree that stretched to the sun. One stormy day, a great gust came. The tree creaked, and cracked, and collapsed! And the tree's new life as a nurse log began...

When old trees fall to the forest floor, they can take centuries to decompose, becoming home to all sorts of organisms along the way. These nurse logs are unique ecosystems that support hundreds of rare and important plants, creatures, and fungi. They provide nutrients for tree seedlings, hideaways for animals, shelters in the winter, and protection from the elements. With snappy text and lush illustrations, this book invites curious readers to step into a tiny ecosystem that's truly like no other.
