Joshua Tree and Climate Adaptation

Scientists predict that much of the Joshua tree's natural habitat in the Mojave Desert will be lost due to the impacts of climate change by the end of the century. Factors such as drought, wildfire, and the tree's symbiotic relationship with the yucca moth are contributing to its decline. A recent study also found that some yucca moths, which are essential for the Joshua tree's reproduction, are not able to thrive in the few areas where the tree is able to survive rising temperatures.

In response to these challenges, the Joshua Tree Genome Project was launched to study the tree's local adaptation to climate change. The multi-year project aims to examine the interrelationships between the physiology of yucca trees and their environmental traits, and ultimately to sequence the Joshua tree genome in order to better understand how the tree grows and responds to its surroundings. By gaining a deeper understanding of the tree's genetics and biology, scientists hope to be able to develop strategies to help the Joshua tree adapt to a changing climate and preserve its unique ecosystem.
