Yosemite Conservancy Partners on Once-in-a-Century Wildlife Book with Beth Pratt and Robb Hirsch

YOSEMITE NATIONAL PARK (Dec. 1, 2021) — Yosemite Conservancy has partnered with conservation leader and author Beth Pratt and photographer Robb Hirsch to publish the first in-depth account of wildlife in Yosemite National Park in almost 100 years.

Yosemite Wildlife is intended to inspire wonder and educate, and will fill a niche that has only been occupied by field guides in the past 100 years. While Yosemite is home to more than 400 species of vertebrates across varied habitats from 1,800 to 13,000 feet elevation, the last single book showcasing park wildlife was Grinnell and Storer’s Animal Life in the Yosemite of 1924.

Yosemite Wildlife will:

  • Include more than 200 photographs, highlighting animal life on the Valley floor, its big walls, in sequoia groves, and high country.
  • Feature some of the most common animals that park visitors may encounter, such as mule deer and marmots; as well as park and Sierra Nevada endemics, like the Yosemite great grey owl and Yosemite toad; and remarkable lesser-known wildlife such as the Yosemite cave pseudoscorpion and Sierra Nevada red fox, and more.
  • Celebrate the park’s rewilding successes and consider creatures that might one day roam within its boundaries.

“This is the book of a lifetime for me,” said Pratt. “I have been wandering in Yosemite for over 30 years, observing and studying the park’s wild world. This landmark work will both celebrate the park’s wildlife and help further scientific understanding.”

Yosemite Wildlife is planned to be released in 2023 – the same year as the Conservancy’s 100th anniversary.

“We are passionate about Yosemite’s natural history,” Hirsch said, “and committed to make this information engaging and accessible for the public.”
