In 2018, we’ll have the adventure of California natural history on both the west and east side of the Sierra Nevada!  The course will start in Yosemite at the UC Merced Yosemite Field Station. We’ll spend October 3 exploring the immense diversity of ecology, geology, and climate as we cross Tioga Pass from Yosemite Valley to Mammoth Lakes.  We’ll spend the remainder of the course at the UC Santa Barbara Sierra Nevada Aquatic Research Lab, just outside the town of Mammoth Lakes.  This is the second year and the first CalNat certification course to offer such a range of California natural history.

Comments from students in past programs

October 2017 - Trans-Sierra

"My expectations were far exceeded. I thought there would be university level lectures – the level of personal interest, professionalism and effort to help us develop naturalist skills is by far one of the most memorable learning experiences I have had."

"This course really helps foster lifelong learning and curiosity. So many more questions arise then answers during the course which is great because it makes you excited to continue growing, learning, researching well beyond the time constraints of the course."

November 2015- Yosemite

"I expected to learn interpretation skills, but because I know a lot about California nature already, I didn’t expect to learn much and I was a little afraid of being bored.  I was so wrong!  Yes, I learned lots of great interpretation ideas/skills, but also tons of California nature, was never remotely bored...It was a wow experience!"

"I generally thought it was going to be something like my lecture classes in college but it was actually better."

"I will always remember this week as an important part of my journey into becoming a naturalist.  I leave with great enthusiasm and even more passion for California natural history."
