Air Quality Conditions
Smoke levels from the Detwiler Fire are expected to increase in the Yosemite area over the next few days as the atmospheric conditions stabilize and bring the smoke to ground level. Mariposa County's Air Pollution Control District has issued an Air Quality Alert. Please see the link below for recommended actions for each level from the Air Quality Index.
You may view current air quality conditions in the park by going to the air quality monitoring site:
Additionally, we are setting up a portable monitor in El Portal. You can view that monitor at this link:

Croaking Toad Lecture Wednesday July 26, 8-9 AM
"Revealing Movement Patterns of Yosemite's Migratory Birds" by Steven Albert, The Institute for Bird Populations, Heydi Rosales, Wildlife Conservation Society, and Sarah Stock, Yosemite National Park
The annual migration of birds is one of the most intriguing and mystifying aspects of the natural world. Learn how biologists are using genetic markers and archival micro-GPS to reveal insights into seasonal songbird movements. We will highlight the movements of Black-headed Grosbeaks from Yosemite to molting grounds in northern Mexico and eventually to wintering grounds in southern Mexico. In addition, Heydi Herrera will talk about her work in Cerro Saslaya National Park and the Bosawás Biosphere Reserve in Nicaragua, areas of stunning biological diversity.
This lecture will take place in the El Portal Large Break Room on Wednesday, July 26, from 8-9 am. Please contact Mitzi Thornley at 379-1060 with any questions. (S. Stock)
New Report: Predicting Climate Change Impacts on Future Distributions of Sierra Nevada Whitebark and Foxtail Pines
A newly published report shares modelling approaches to predict climate change impacts on the future distribution of the iconic high-elevation whitebark pine and foxtail pine within Sierra Nevada national parks. This report was a collaborative effort among the USGS Yosemite Field Station, the University of California at Merced, and the former Sierra Nevada Network Ecologist who is currently affiliated with the USGS in Maine.
Report Citation: Moore, P. E., O. Alvarez, S. T. McKinney, W. Li, M. L. Brooks, and Q. Guo. 2017.

Whitebark pine and foxtail pine serve foundational roles in the subalpine zone of the Sierra Nevada. They provide the dominant structure in tree-line forests and regulate key ecosystem processes and community dynamics. Climate change models suggest that there will be changes in temperature regimes and in the timing and magnitude of precipitation within the current distribution of these species, and these changes may alter the species’ distributional limits. Other stressors include the non-native pathogen white pine blister rust and mountain pine beetle, which have played a role in the decline of whitebark pine throughout much of its range. The Sierra Nevada Network is monitoring status and trends of these species. (L. Mutch)

Visitors without reservations may experience up to a 3 hour wait for a parking space. Once you drive into Yosemite Valley, the park encourages visitors to park once and explore the Valley Floor by bicycle, on foot, or by taking advantage of the park’s free shuttle service to all major Valley attractions.
