Beth Pratt, wildlife advocate and author, has worked in environmental leadership roles for over thirty years, and in two of the country's largest national parks: Yosemite and Yellowstone. Pratt leads the National Wildlife Federation's #SaveLACougars campaign to build the Wallis Annenberg Wildlife Crossing outside of Los Angeles. Her innovative conservation work has been featured by the New Yorker, the Wall Street Journal, the Washington Post, BBC World Service, CNN, CBS This Morning, the Los Angeles Times, Men's Journal, the Guardian, NPR, AP News, and more. She is also the author of I Heart Wildlife and When Mountain Lions are Neighbors. Beth makes her home outside of Yosemite, her "north star," with her dogs and cats, and the mountain lions, bears, foxes, frogs, and other wildlife that frequent her backyard.

Robb Hirsch studied ecology and worked as a field biologist for the California State Parks, USGS, and private biology firms prior to his nature photography career. He publishes his images in books, calendars and magazines and leads photography workshops throughout the Sierra Nevada. His primary focus is using quality imagery for outreach, education and conservation, facilitating a deeper appreciation of the natural world. Robb is the author/photographer of The Nature of Yosemite: A Visual Journey. He and his wife, Regina, own Mountain Sage, a gallery-café-plant nursery in the Yosemite gateway community of Groveland, CA, where he lives.

"From the cute but ferocious river otter to the gliders of the night, the Humboldt's flying squirrel, this striking book is the first comprehensive work in more than a century dedicated to the park's animal kingdom." --Associated Press

"With more than 300 images, Yosemite Wildlife is also rich in Pratt's accessible prose; this thorough survey of observations and storytelling is designed to update a 1924 publication for the historical record. As a beautifully produced, large-format, glossy presentation, it also exhibits Pratt's and Hirsch's expertise and passion for a place that is much more than just its famous geology and dramatic scenery. With plentiful archival records, historical images, and personal stories from park staff and naturalists, it's an informative document as well as a stunning visual feast. . . . Exquisite." --Julia Kastner of pagesofjulia for Shelf Awareness
