An intimate look at one majestic hundred-year-old oak tree through four seasons--and the reality of global climate change it reveals. In the life of this one grand oak, we can see for ourselves the results of one hundred years of rapid environmental change. It's leafing out earlier, and dropping its leaves later as the climate warms. Even the inner workings of individual leaves have changed to accommodate more CO2 in our atmosphere. Climate science can seem dense, remote, and abstract. But through the lens of this one tree, it becomes immediate and intimate. In Witness Tree, environmental reporter Lynda V. Mapes takes us through her year living with one red oak at the Harvard Forest. We learn about carbon cycles and leaf physiology, but also experience the seasons as people have for centuries, watching for each new bud, and listening for each new bird and frog call in spring. We savor the cadence of falling autumn leaves, and glory of snow and starry winter nights. Lynda takes us along as she climbs high into the oak's swaying boughs, and scientists core deep into the oak's heartwood, dig into its roots and probe the teeming life of the soil. She brings us eye-level with garter snakes and newts, and alongside the squirrels and jays devouring the oak's acorns. Season by season she reveals the secrets of trees, how they work, and sustain a vast community of lives, including our own. The oak is a living timeline and witness to climate change. While stark in its implications, Witness Tree is a beautiful and lyrical read, rich in detail, sweeps of weather, history, people, and animals. It is a story rooted in hope, beauty, wonder, and the possibility of renewal in people's connection to nature.

Mike Sullivan loves his adopted city of San Francisco, and he loves trees. In The Trees of San Francisco he has combined his passions, offering a striking and handy compendium of botanical information, historical tidbits, cultivation hints, and more. Sullivan's introduction details the history of trees in the city, a fairly recent phenomenon. The text then piques the reader's interest with discussions of 71 city trees. Each tree is illustrated with a photograph--with its common and scientific names prominently displayed--and its specific location within San Francisco, along with other sites; frequently a close-up shot of the tree is included. Sprinkled throughout are 13 sidelights relating to trees; among the topics are the city's wild parrots and the trees they love; an overview of the objectives of the Friends of the Urban Forest; and discussions about the link between Australia's trees and those in the city, such as the eucalyptus. The second part of the book gets the reader up and about, walking the city to see its trees. Full-page color maps accompany the seven detailed tours, outlining the routes; interesting factoids are interspersed throughout the directions. A two-page color map of San Francisco then highlights 25 selected neighborhoods ideal for viewing trees, leading into a checklist of the neighborhoods and their trees.

In Native Trees of Western Washington, Washington State University's Kevin Zobrist examines regional indigenous trees from a forestry specialist's unique perspective. He explains basic tree physiology and a key part of their ecology--forest stand dynamics. He groups distinctive varieties into sections, all lavishly illustrated with full-color photographs. The result is a delightful and enlightening exploration of regional timberlands.
