The Sierra Nevada Mountains supply two-thirds of California’s water supply. Meadows in these mountains capture rain and snow, making water available throughout the year. Earthwatch Program Delivery Assistant Anna Woodroof spent time restoring and monitoring this ecosystem in order to better understand potential threats to water supply and biodiversity due to climate change on the expedition Restoring Meadows in the Sierra Nevada Mountains.
As an East Coaster, I find the landscapes of the West amazing, unlike anything we have at home. The cliffs and valleys seem to invoke a Disney-like magic like the backdrop of a movie set. I recently joined the Earthwatch expedition Restoring Meadows in the Sierra Nevada Mountains, where I worked in meadows at the elevation of some of the highest mountains on the East Coast, surrounded by even higher peaks. The expedition was a combination of challenging physical work, a huge sense of accomplishment, and periods of serenity where I was able to enjoy the vast landscape and reflect on all that I was seeing. I loved learning about the importance of the meadows for the community and for the greater California state.
Reno, Nevada wasn’t the first place I would think to go for quick access to some of the most beautiful landscapes the United States has to offer. But my recent participation on this week-long Earthwatch expedition, in addition to two one-day programs in the Sierra Nevada meadows (which I describe below), changed that perception. Both projects included beautiful sunny weather and amazing vistas of mountains, massive trees, and golden valleys.
For the week-long expedition, my team participated in the scientific studies of meadows in the Yuba watershed. We worked alongside lead scientist Rachel Hutchinson, as well as other researchers from the South Yuba River Citizens League (SYRCL), to understand how human activities have altered the meadows on the Western-side of the Sierra Nevada and how these changes will impact their response to a changing climate.
Over the course of one week, we installed three groundwater-monitoring wells, collected data on stream water level flows, and identified meadow plant species by collecting several biomass samples. The research took place between long fascinating hikes through Tahoe National Forest with a passionate botanist and enthusiastic hydrologist ready to answer any questions we had. SYRCL is working to create a budget of the carbon released and sequestered in the particular meadows with the hopes of influencing policy with the findings.
The other projects I took part in were one-day events with researchers from the University of Nevada, Reno. This project series – called Sierra to Sea – also studies meadows, but on the Eastern-side of the Sierra Nevada, and strives to recruit locals whose communities will be directly impacted by the study to participate. The volunteers consisted of high school students, college undergraduates and the other community members who spent a Saturday or Sunday with the researchers in the field. We collected biomass samples, measured trees and sagebrush, and learned about the difference between wet and dry meadows when it comes to carbon sequestration. Even though the group volunteered together for one day, I got to know a lot about the people of the region through the local community members who participated.
Learning about the local water source and the science behind carbon sequestration in meadows made me think more about my own community and the processes taking place there. The researchers and community members participating rely on the water and the biodiversity of the meadows and have a personal perspective surrounding the issues. I think both groups learned a great deal from this experience and will take their newfound knowledge back to their everyday lives.
