Preserving the California Black Oak in Yosemite Valley - 2013

Preserving the California Black Oak in Yosemite Valley - 2013

Restoring the California black oaks to Yosemite Valley, vital part of the ecosystem that has been in decline.

California’s black oaks are a vital part of Yosemite’s natural and cultural heritage. These trees and their acorns support a variety of animal species and were a vital food source for American Indians for thousands of years. Over time, the magnificent black oak stands in Yosemite Valley have declined due to rising deer populations and are in need of restoration.

Hundreds of black-oak acorns were planted in existing stands throughout Yosemite Valley, while park scientists observed and recorded causes of low seedling survival rates during this two-year project. Gathering information about black-oak stands is leading to the development of a comprehensive restoration program that will return these trees to full magnificence.

Because of your support, black oaks in Yosemite Valley will continue to inspire generations of park visitors.
