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. Climate change and tree-line ecosystems in the Sierra Nevada: Habitat suitability modelling to inform high-elevation forest dynamics monitoring. Natural Resource Report NPS/SIEN/NRR—2017/1476.

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)

There are a limited number of day parking reservations still available for visitors planning a trip to Yosemite Valley on weekends this August. Securing a free day parking reservation in Yosemite Valley will greatly enhance a visitor’s experience during weekends in August, the park’s busiest month. These reservations are free (with a $1.50 service fee per reservation) and can be booked online  (www.recreation.gov) or by phone at 1-877-444-6777. There are 150 parking spaces available by reservation daily and availability is limited. This is the second year Yosemite National Park is testing a pilot day parking reservation program.
These parking reservations are located in the newly designed Yosemite Falls Parking Area, located directly west of Yosemite Valley Lodge and south of Camp 4 in Yosemite Valley. This parking lot also provides visitors the ability to avoid afternoon traffic congestion when leaving Yosemite Valley.
Visitors who book a parking reservation will be guaranteed a parking space in Yosemite Valley from 7:30 am to 4:00 pm. A reservation is valid for one day only. Reservations are available for passenger vehicles up to 20 feet in length. At this time, reservations cannot be booked for RVs or trailers.
Anyone planning a trip on a Valley Tram Tour, a day hike on the Upper Yosemite Falls Trail, or anyone attending a wedding in Yosemite Valley on any Saturday or Sunday this August are strongly encouraged to book a parking reservation today to guarantee a smooth parking experience. 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.
A great alternative to driving into Yosemite Valley is to consider parking at stops in the Gateway Communities and riding the Yosemite Area Regional Transportation System (YARTS) buses into Yosemite Valley.
