Much of the Sierra Nevada consists of federal lands and is either protected from development or strictly managed. The mountain range is home to three National Parks - Yosemite, Kings Canyon, and Sequoia - and two national monuments - Devils Postpile and Giant Sequoia. Ten national forests span much of the mountain range's remaining area. Within these national parks, monuments, and forests lie 26 wilderness areas, which together protect 15.4% of the Sierra's from logging and grazing.
