Citizen Science and the Race North:
Population Ecology of Joshua Trees In An Era of Climate Change
Friday, March 18 – Monday, March 20, 2016
Meadview, AZ – Joshua trees are one the most unusual and recognizable plants of the Mojave Desert, but the future of these remarkable plants are threatened by ongoing global climate change. Computer models predict that within the next 100 years Joshua trees may disappear from much of their current range, and emerging demographic data suggest that many populations in the southern Mojave Desert are already on their way to extinction. It is possible that the species may be able to survive by migrating to more temperate environments further north, but the trees’ capacity to escape warming climates will depend on how quickly they are able to colonize new habitats. The western edge of the Grand Canyon provides a remarkable venue to study the effects of climate change on Joshua trees. Where the Colorado Plateau meets the Mojave Desert the sweeping hillsides descend over 4000 feet in the space of less than ten miles. Across this gradient a single population of Joshua trees experiences a range of climates as different as Palm Springs is from Bishop, California. This natural laboratory allows us to step into the future to discover how changes in the Earth’s climate may affect the reproduction and survival of Joshua trees. During a three-day citizen science program, participants in this course will contribute to ongoing scientific research on the population ecology of this most famous Mojave Desert species.
