Braided River has released photographer Amy Gulick's latest ecosystem photo book, "Salmon in the Trees: Life in Alaska's Tongass Rain Forest." In the book, Gulick's images are partnered with essays and research from leading scientists, conservationists and journalists, who pose the question "How long can the biological riches of the Tongass withstand the global demands for timber, seafood, and minerals?" Contributors include Richard Carstensen, Douglas Chadwick, Brad Matsen, Richard Nelson, Carl Safina, John Schoen, John Straley, and Rosita Worl.

The 176-page hardcover, with 160 color photos and five color maps, retails for $30 and includes a CD.
