Mapping Joshua trees across the Mojave

If you live in, visit, or care about the Mojave Desert, you’re probably quite familiar with the ungainly silhouette of its most iconic resident: the Joshua tree. Yucca brevifolia and its related species Yucca jaegeriana are endemic to the Mojave Desert, meaning that they’re not found anywhere else on earth. As the manifestations of climate change multiply, even that restricted range is likely to shrink, when low-elevation and southerly populations struggle to adapt to hotter conditions.
