About the Holiday
International Day of Forests was instituted by the United Nations General Assembly in 2011 to raise awareness of the importance of trees in vast woodlands or in your neighborhood or yard. Trees contribute to the quality of the air we breathe, improve the local climate, reduce noise pollution, shelter wildlife, and provide food for people and animals. This year’s theme is “Forests and sustainable production and consumption.” So many aspects in our lives – from the materials for building homes, making tools, developing new household items, and more to the medicines we take, the water we drink, and the clothes we wear rely on healthy and sustainable forests. This year’s theme encourages people to think about the ways forests benefit not only human life but the wildlife and the earth as a whole. For more information visit the UN International Day of Forests website and The Geneva Environment Network.
Thanks to Boyds Mills for providing a digital copy of The Leaf Detective for review consideration. All opinions on the book are my own.

The Leaf Detective: How Margaret Lowman Uncovered the Secrets in the Rainforest
Written by Heather Lang | Illustrated by Jana Christy
As a child, Meg was quite shy to make friends. She spent lots of time studying and playing with wildlife: “Meg wrapped herself in nature, like a soft blanket.” As she continued to grow, so did her passion for leaves, trees, and nature. Meg attended Sydney University in Australia. In 1979, she became the first person at her graduate school to study the rainforest. Through her studies Meg learned that people had been all the way to outer space to study, but nobody had ever ventured to the tippity top of a canopy tree. Instead, they studied trees from far away through binoculars. Oftentimes scientists would spray trees with chemicals so that the harmed leaves and animals would drop to the forest floor where people could study them up close. Meg sought to change this.

“In the dark, damp forest the trees rose up to distant rustling, squawks and screeches, shadows in the treetops. How could she get up there?” Meg Lowman created her own slingshot and harness and inched up a coachwood tree. When she reached the canopy, she knew she’d found the perfect place to study and explore. Meg is quoted saying, “From then on, I never looked back…or down!”
Meg continued to create new strategies to study the canopy, as a scientist does. And in doing so she made so many discoveries, such as: “We now believe the canopy is home to approximately half the plant and animal species on land.” Many people tried to stop Meg along her journey. They told her she couldn’t take science classes, climb trees, or make inventions because she was a woman. But Meg ignored them. She continued to investigate.
She knew that rainforests were (and are) in danger, and that so many creatures rely on the rainforest ecosystem. People all over the world were cutting down large parts of the rainforests for wood, rubber, paper, and farmland. This worried Meg; she wanted to find a way to protect rainforests before they all disappeared. “She wondered, How can one leaf detective make a difference? How can I save the trees?…Then an idea crawled into Meg’s thoughts—a way to speak for the trees.”

Meg traveled around the world. She spoke to people across many different countries; taught them how to climb trees, build canopy walkways—she showed people the many gifts rainforests have to offer. Meg educated communities on how they could share their rainforest with outsiders, showcase its beauty to create revenue rather than chopping them down for resources. By using her voice and creative mind, Meg helped implement systems that have saved many trees and creatures across the world.
Meg Lowman continues to study trees, save rainforests, and teach people how to shift their economies to center around ecotourism and sustainable crops rather than resource extraction. She has used her voice to save rainforests across the world, and yet she still says, “If only I could have achieved as much as the tree!… But I have not. I have whittled away at relatively small goals in comparison to the grander accomplishments of a tree.”
Backmatter includes an author’s note detailing Heather Lang’s visit to meet Margaret Lowman in the Amazon rainforest in Perú. The note includes more information on Dr. Lowman’s advocacy work and is followed by an illustrated educational spread on the layers of canopies, and species featured throughout the story are labeled in the final spread, for readers to learn more about specific animals that make their homes in the rainforest.

Heather Lang’s lyrical writing matches the carefulness with which Meg studies leaves, trees, and the rainforest canopy. Her compelling storytelling is rich with facts and sensory imagery that immerse readers in the environment and Meg’s determination to understand and, later, save it. Scattered images of leaves drop fun facts and definitions for readers about the rainforest, canopies, transpiration, herbivores, and more. Quotes from Dr. Lowman are thoughtfully placed throughout the story in a manner that neatly flows. The Leaf Detective urges readers to understand that “a tree is not just a tree” but rather “a shelter for animals and people, / a recycler and provider of water, / a creator of food and oxygen, / an inventor of medicine/ a soldier against climate change.”
Jana Christy’s digital drawings contain stunning detail and show an accurate scale of one small person in comparison to the vastness of the rainforest. Her mesmerizing wildlife creatures and immersive watercolor blues and greens transport readers right into the rainforest with “Canopy Meg.” The lush greens of the rainforests contrast strikingly with the spread on deforestation, in which fallen trees lay scattered on the bare, brown ground. Readers will also be interested to see the innovations that have made the trees more accessible to people. One can read the book over and over and notice new details every time. It is a book to treasure, to study, to read and re-read again.
Come unearth the secrets of the rainforest with Margaret Lowman in this book that’s budding with knowledge, empathy, and magic, and is a tale of how one person can make a difference. The intriguing facts, poignant quotes from Dr. Lowman herself, and beautiful poetic writing will leave readers of this book inspired with wonder and with a hunger for advocacy. The Leaf Detective: How Margaret Lowman Uncovered the Secrets of the Rainforest is an urgent must-read for all ages.
A portion of Heather Lang’s royalties for this book go to TREE Foundation—an organization that funds field trips for children to get into nature, canopy projects, and science book distribution for children with limited access to STEAM, girls especially.
Ages 6 – 10

Today I am thrilled to be interviewing author Heather Lang about her new biographical picture book The Leaf Detective: How Margaret Lowman Uncovered the Secrets of the Rainforest. Heather provides some thoughtful notes for shy readers, riveting stories from the rainforest and insight into the importance of exploring and caring for nature.
Can you tell us a little bit about what made you decide to write The Leaf Detective?
We’ve caused enormous harm to our planet over the last few centuries, and I’m especially concerned about our rainforests. I knew I wanted to write a biography that was also a science book about the rainforest. When I read about Meg’s pioneering work and deep passion for trees, I was hooked! I couldn’t wait to find out how this quiet, nature-loving child, who didn’t know women could be scientists, became a world-class scientist and conservationist.
In the story you talk about how Meg was shy to make playmates with other kids. Were you also a shy kid growing up? Do you have any advice for readers who may relate to this aspect of Meg’s childhood?
Like Meg, I was very shy as a child and remember wishing I were more outgoing. But as I grew older, I began to recognize the many advantages to being shy! My shy nature led me to sit back and observe. And that led to deeper thinking and understanding, a strong imagination, and creativity. Shy people often think more before they speak. They make their words count, which coincidentally is an important part of writing picture books. This also makes shy people good listeners and thoughtful friends.
I’m still shy in many ways, and my recommendation to readers who might identify with this is to embrace your shyness! At the same time, don’t let it stop you from doing things you want to do. Meg Lowman told me she used to get so nervous before presenting in graduate school that she’d get physically sick. But with practice, practice, practice, she’s become a captivating presenter and educator. If you watch a few of her FUN FACTS FROM THE FIELD videos on my website, you’ll see what I mean!
How would you describe your connection to nature? Would you consider yourself a “detective” in any ways?
I’m constantly in awe of nature and its countless gifts and surprises. Nothing sparks my curiosity more than our natural world, and my curiosity is probably my most important tool as a writer. Being open-minded and asking questions not only generates ideas, but also leads me to think more deeply about a topic and examine it closely from lots of different angles. And of course that generates more detective work and more learning about my topic and myself. Being a detective is one of my favorite parts of writing books.
Do you have a favorite rainforest tree or creature? If so, tell me about it a bit!
When I arrived in the Amazon rainforest, I couldn’t wait to see a sloth! But during my time there I became fascinated with ants. They are everywhere in the rainforest, even in the canopy. I think it’s amazing how such tiny creatures can be so hardworking and organized. Their teamwork is unbelievable. And they are invaluable to the health of our rainforests. Among other things, they’re in charge of waste management on the rainforest floor, and they disperse seeds and aerate the soil!
What was the most rewarding part of writing The Leaf Detective?
This writing project was filled with rewards every step of the way! I learned so much about our rainforests and trees and gained a true understanding of how interconnected we all are—plants, animals, and humans. Getting to really know Meg Lowman and learning from her firsthand was thrilling and strengthened my writing in many important ways. It was also really rewarding to stretch myself as a writer and find a way to effectively write a book that seemed ambitious at first—a biography and conservation book that wove in quotes and science facts.
Are there any stories from your trip to meet Meg that you did not get the chance to include in your author’s note that you’d like to share?
While I was on my Amazon adventure with Meg, I had many exciting moments. I loved learning from the Indigenous people how to use a blow gun, make clay, and braid palm leaves to make thatched roofs. The local shaman taught me how he uses different plants in the rainforest to treat and prevent injuries and illnesses—from bronchitis to poisonous snake bites. He also helped me confront my fear of snakes by bringing one over for me to touch. I even let it gently coil around my neck! But my favorite moments were exploring with Meg, especially at night and early in the morning when there’s so much activity in the rainforest.
Thanks so much for chatting with me Heather! I had a lovely time hearing about your inspiration, stories, writing process and tips for shy readers. Looking forward to learning and reading more from you in the months and years to come.
