Conservation Status
There is some concern from modeling that Joshua trees will be eliminated from Joshua Tree National Park due to climate change, and that this will damage and fundamentally transform the ecosystem of the park. There is also concern about the ability of the trees to migrate to favorable climates due to the extinction of the giant Shasta ground sloth (Nothrotheriops shastensi) 13,000 years ago; ground sloth dung has been found to contain Joshua tree leaves, fruits, and seeds, suggesting that the sloths might have been key to the tree's dispersal.
