Sequoia trees can live up to 3,000 years. Yosemite Park hosts many 1,800-year-old trees. When the park was created, the focus was first and foremost to show the magnificent trees to visitors. Now, Yosemite will invest $40 million to restore the natural habitat of the trees—replacing asphalt with walking paths and removing commercial activities from the grove—so that their natural wonder can endure.
