When a Tree Falls....

 

When a Tree Falls: Nurse Logs and Their Incredible Forest Power 

by Kirsten Pendreigh; illus. by Elke Boschinger 

44 pages; ages 6-9

Chronicle Books, 2025

theme: trees, ecology, nonfiction

A tall tree suns and sways. She is a place to grow, to rest, to shelter.

Over time and seasons we see what animals nest on the boughs, chip into the bark and, after the tree crashes to the forest floor, hide beneath the fallen trunk. Using lyrical language, Kirsten Pendreigh shows readers how the fallen tree nurtures new life.

What I like about this book:

The language is beautiful and spare – just enough words to convey meaning without cluttering up the page. This leaves lots of room for the beautiful illustrations by Elke Boschinger. I love how she tucks fungi along the edge of the tree, and the details of the mosses growing on the trunk – these are the same things I find on fallen trunks in the woods behind my house.

I like the arc of the story, which spans many years over which children grow into adults with their own children, who they bring into the forest to admire the trees. And I really like that Kirsten includes back matter that explains what nurse logs are, how they nurture new life, and how they keep the forest healthy. 

Kirsten graciously answered a Couple Questions: 

Me: When did you know you had to write this story about Doug fir and hemlock?

Kirsten: I've been fascinated by nurse logs since I first moved to the West Coast 30 years ago. Trees growing out of other trees! I felt there was something profound happening, and noticed how kids gravitated to these tree nurseries. About six years ago, while hiking the trails near my home, a refrain came into my head and became kind of an incantation. "A tall tree suns and sways...she is a place to grow, to rest, to shelter." The words kept building and became a life cycle story I was excited to write, and share with little ones.

Me: I love that you say in back matter that all species are connected and we all need to help one another. Did this guide your writing of this book?

Kirsten: I'm not sure it guided the writing but it was just organically there all along. I didn't know when I started writing that Douglas firs themselves typically don't grow out of nurse logs even though nurse logs in this part of the world are typically fallen Douglas firs! Western hemlocks are the most common species to grow out of Douglas fir nurse logs, so right there is a clear example of a deep connection. I learned that nurse logs help salmon survive, when they fall across streams they create sheltered pools for young salmon to grow. We are starting to understand how crucial it is to have diversity in the forest; how webs of life depend on a variety of species, how single species stands of trees are not as resilient as diverse forests. The more you look, the more you see these interconnections in nature. There is such strength in diversity. I hope it's an understanding people can take beyond the forest.

Beyond the Books:

Observe a tree. Describe what does it look like from far away. Now get under it and look up. How would you describe it? Draw a picture or take photos of your tree from different points of view. 

Examine a fallen log. What do you notice growing on the trunk? What about beneath it? Can you tell what kind of tree it is and how old it is? Are there any baby trees growing on it?

Stand tall like a tree. Here’s a video showing a kid-friendly yoga “tree pose.” Can you feel yourself rooting into the earth?
