*Many readers think of animals when they hear the term keystone species, but this book spreads the word about how the hard-working oak tree also serves as a keystone in its environment. Lyrical descriptions of main points introduce each spread, such as how the oak tree shelters insects through the winter. . . . Paintings show the variety of life that depends on the oak, from white-tailed deer and black bears to field mice and fungi. Nearly everything is labeled for easy identification. Some images show the entire tree and its surroundings, while others zoom in for a closer look at leaf litter or the insects that create homes in acorns. . . . Highly recommended for the layered text and intricate illustrations that make this a wonderful read-aloud for younger grades, while offering plenty of information for budding botanists.

In this arbor-centric work of children’s nonfiction, readers get to track the growth of a large oak tree through the seasons and are introduced to the various birds, animals, and insects that benefit from all the tree has to offer, from acorns to shelter to filtered air. . . the text moves with a poetic cadence as it expounds upon all the interactions between the tree and its various denizens. Watercolors blend seamlessly between scenes of winter into spring, showcasing especially the rich soil that sustains the oak, while shifts in perspective demonstrate the stages of the oak’s life. . . Gianferrari does an excellent job balancing artful, rhythmic prose with easily grasped concepts and factual accuracy. . . [this book] is sure to please young plant lovers and tiny artists alike—though even readers who do not find themselves drawn to the science side of things will be drawn to the colorful artwork and poetic writing.

*In a richly illustrated picture book that’s chock-full of ecological facts, Gianferrari and Sudyka venerate the astounding oak for its critical role as a keystone species. Employing anaphora, assonant lines highlight the many varied roles a single tree plays for a multitude of species across the seasons . . . Accompanying captions dive deep into adjacent topics, introducing concepts including marcescence (when a tree’s withered leaves remain attached) and the brown food web (the recyclers and decomposers who reside in leaf litter). . . . the text goes on to celebrate the deciduous specimen’s roots (“farther than/ the canopy is wide”), acorns (“a nutritious superfood!”), and its important functions cleaning air and preventing erosion. Spreads depicting an abundance of goggle-eyed critters washed in watery earthy hues incorporate labels for a field guide–like effect that IDs myriad flora and fauna living in concert with a lone tree. It’s a satisfyingly comprehensive and appreciative portrait of oaks and their numerous contributions.

*Gianferrari and Sudyka explore the many life forms and natural processes—both visible and invisible to the naked eye—that a single oak tree “nurtures and nourishes.” From feeding and sheltering wildlife above- and belowground to producing oxygen and preventing soil erosion, and beyond, the oak touches everything around it, forming a micro-ecosystem of its own. Gianferrari’s text, with its frequent alliteration, occasional rhyme, and refrain of “just one oak,” constitutes an ode to the “beautiful and bountiful” tree’s life-giving power. Sudyka’s vibrant, painterly illustrations enrich the reading experience, zooming in and out as necessary to put a spotlight on different aspects of the oak-ecosystem.

A joyous tribute to the many roles one living tree can take—from creating a microclimate to feeding and housing a wide variety of wild creatures. In a mix of lyrical general statements and expansive notes in smaller type, Gianferrari describes how oaks offer a “dining room” for more types of moths and butterflies than any other native tree genus and a winter granary for woodpeckers, which drill holes where they stash acorns. . . . In her painted illustrations, Sudyka envisions a mature tree teeming with wildlife, from googly-eyed bugs to birds and bears—nearly all identified with discreet labels—as well as associated flora, fungi, and, in a final scene, a racially diverse set of young tree lovers. . . . Offers plenty of cause to root for this keystone species.
