The peregrine falcon thrives in Yosemite Valley, but this remarkable bird was temporarily extirpated from much of its native range, including Yosemite where it disappeared for decades, leading to its listing as an endangered species in the early 1970s. Because of the remarkable, collaborative efforts of Yosemite climbers, UCSC Predatory Bird Research Group, and NPS biologists, with generous funding from the Yosemite Conservancy, the story of Yosemite’s peregrine falcon is one of hope.
Can we save the Sierra Nevada yellow-legged frog from extinction? Human introduced non-native species (fish and fungus) have been causing the frog to go from the most abundant amphibian in the Sierra Nevada to critically endangered. However, habitat restoration efforts in Yosemite are showing promising signs for the frog's recovery and long-term survival.
When faced with harsh and extreme conditions, how do organisms survive, thrive, and persist?
Plants living on the steep granite walls surrounding Yosemite Valley manage to survive and reproduce despite constant exposure to harsh environmental conditions such as wind, heat, limited soil, and seasonal water availability. However, little is known about the underlying mechanisms that have allowed for plant populations to adapt to this intense environment.
