The three new monuments–Mojave Trails National Monument, Sand to Snow National Monument, and Castle Mountains National Monument–are all a part of California’s desert ecosystem. A White House fact sheet says that the new monuments “will link already protected lands, including Joshua Tree National Park, Mojave National Preserve, and fifteen congressionally-designated Wilderness areas, permanently protecting key wildlife corridors and providing plants and animals with the space and elevation range that they will need in order to adapt to the impacts of climate change.” Say hello to our newest national monuments in the gallery.
