Date: January 27, 2014

Explore phenology, "the science of the seasons", at Joshua Tree National Park in a free, one-day workshop. Engage in citizen science and learn how you can volunteer to help the park detect the impacts of climate change by observing the seasonal activities of the park's desert plants, from bud-burst to flowering and fruiting. The California Phenology Project has been launched to implement a monitoring program focused on national parks in California.

Dr. Susan Mazer, a professor of plant ecology, genetics, and evolution at University of California, Santa Barbara is researching the processes and results of evolution by natural selection, specifically as it pertains to vegetation. She will lead this workshop and share her extensive knowledge of species and plant communities ranging from South American tropical rainforests, to remote regions of the southern Sierra Nevada, to the central coast of California.

Join us on Saturday, February 1, 2014, at Joshua Tree National Park headquarters in Twentynine Palms. The group will meet at the Oasis of Mara from 1-5:00 pm.

Bring snacks,water, sunscreen, appropriate layered clothing for the predicted temperatures, a notebook and pen. If interested in this opportunity, please contact Josh Hoines at 760-367-5564, or at Josh_Hoines@nps.gov.
