Why are the Joshua Tree's dying? Through a hollowed out section of a dead tree another living Joshua Tree sits in the setting sun.
Experts expect the Joshuas to vanish entirely from the southern half of California within a century.
The ancient plants are dying in the #JoshuaTree National Park. Already slow and difficult reproducers by nature the Joshua trees are the victim of global warming and its symptoms -- including fire and drought -- plus pollution and the proliferation of non-native species.
The #Seussian looking trees are really plants, a relative of the yucca.
Joshua trees are a foundation species, providing habitat for other animals that otherwise would disappear. @Robert Clark @thephotosociety @instituteartist @ナショナルジオグラフィック
