One way to understand climate change is by climbing to extremes. In this episode of Unfold, co-host Kat Kerlin trekked up some of the highest peaks in the Sierra Nevada range with UC Davis ecologists with the goal of finding high-altitude Jeffrey pine trees. Their presence can reveal a lot about our warming planet. We’ll hear about her trip – and how a little bird “gardener” can play a large role in reshaping California’s forests.
In this episode:
Hugh Safford, UC Davis forest ecologist
Sachi Srivastava, UC Davis graduate student
Mike Mahoney, UC Davis doctoral student
Nick Parker, UC Davis undergraduate
