We seek individuals with passion for conservation and research in challenging conditions, and extensive mountain experience. Follow the link for a detailed job description and application instructions.
Over the past quarter century, we have documented dramatic, disease-driven declines of mountain yellow-legged frogs across California’s Sierra Nevada. Recently we have documented the beginning of their recovery. To study these declines and recovery in 2021, we will hire two field technicians for the summer field work. As part of our team, the technicians will primarily conduct frog population surveys, disease surveys, and translocations/reintroductions. Our study sites are lakes, ponds, and meadows across the remote, alpine Sierra Nevada landscape. We often backpack 10-20+ miles to reach study sites, and for 3-10 days we camp and work in all conditions. The field technicians spend the majority of the 2-3 month position working and living in the backcountry. Despite this challenging work environment, we are motivated by the positive impact that our research has on frog recovery.
“What do frogs do in winter?” That is a question we hear frequently. Meters-thick ice covers high elevation Sierra Nevada lakes for about nine months of the year. For an animal that spends summer days lounging on rocks in the sun, winter imposes a radical shift in lifestyle. But historically, we could not document frog winter behavior through direct observation. Although scuba diving allows observation of some taxa, winter ice, elevation, and remoteness prevent us from diving in Sierra lakes.
Enter David Lang and his team, who developed the Trident underwater drone at OpenROV and Sofar Ocean Technologies. Over the past few years, our team used a Trident to search for frogs in a frozen lake. This technology allowed us to find frogs and tadpoles, and to capture video to document their overwintering behavior. David and some of his colleagues joined us at our study lake on two late winter expeditions and experienced our “eureka” moments in which we saw frogs and tadpoles as never before. Through the lens of the Trident and the VR goggles, we finally saw the frog’s eye view of life under the ice.
In his recent OneZero article, David describes how the Trident makes this project possible. More generally, he explores the potential for tech to enhance conservation projects. We are happy to see David’s story published, and honored that he focused on our project. Read his story here.
