These data represent occupancy surveys conducted in long-term monitoring sites in Yosemite National Park in 2018 for three anurans, the Yosemite Toad (Anaxyrus canorus), the Sierran Treefrog (Pseudacris sierra), and the Sierra Nevada Yellow-legged Frog (Rana sierrae). The data include independent double-observer surveys and time-to-detection data to calculate detection probabilities and account for false negatives, or the failure to detect a species at a site where it occurs.
These data support the following publication:
