Yosemite Forum Today
"Fire, Drought, and Big Trees" by Dr. James Lutz, Utah State University
Fire and drought are both characteristics of the Sierra Nevada.  Fire exclusion in the 20th century has probably made the consequences of fire and drought more severe, leading to higher levels of tree death.  Using data from the Yosemite Forest Dynamics Plot, the largest forest monitoring plot in the National Park system, Jim Lutz will discuss changes in this mixed-conifer forest from 2010 to 2016, capturing the dynamics of the Rim Fire and the subsequent drought.
The Forum will take place today, March 14th from 3:30 to 4:30 pm in the Yosemite Valley Auditorium.  Please contact Ami Knighten at 379-1301 for additional information.  (G. Stock)
Traffic Disruption near Valley Gas Pumps Today
The traffic lane immediately west of the AT&T building will be closed Tuesday afternoon, March 14th through late Wednesday for replacement of electric lines.  Access to the gas pumps and utility area will be re-routed and a few parking stalls will be closed.  (K. White)
Data as a Legacy: Information Management and Long-term Monitoring
Each field season the Sierra Nevada Network Inventory & Monitoring Program (SIEN) sends crews out to lakes, high-elevation forests, bird-monitoring sites, and wetlands all over Sequoia & Kings Canyon National Parks (SEKI), Yosemite National Park (YOSE), and Devils Postpile National Monument (DEPO) to collect data on the condition of park resources. To ensure the data they collect are available for current and future managers and scientists, it’s critical that those data are well-documented, managed, organized, and archived.
SIEN initiated a review of its data/information management program in February 2016 to give a broad overview of the status of data management in the program, uncover specific deficiencies in the system, and identify areas for future improvement. Peter Lindstrom, Data Manager in Yosemite National Park, conducted the review. He collected information from published documents and network files, interviews with SIEN staff, and a survey of natural resource staff at network parks. His report is now available at:
The Sierra Nevada Network thanks Peter for his thorough work and insights, Yosemite National Park for making him available, the Inventory & Monitoring Division for funding the detail and providing helpful input, and all the park staff from SEKI, YOSE, and DEPO who responded to survey questions and provided thoughtful input and comments that informed the evaluation.  (L.

Yosemite National Park Continues Work to Repair Big Oak Flat Road - News Release March 13, 2017 
Highway 41 opened to one-lane traffic 
Yosemite National Park continues work to repair the Big Oak Flat Road (continuation of Highway 120 ) leading to Yosemite Valley. Severe winter storms have impacted the road and it has been unsafe for vehicular travel since late February. The park is working with Federal Highway Administration officials and contractors to completely assess the situation and design and implement repair work. There is no estimated date for the road to reopen.
Significant rain and snow this winter has saturated the soils, resulting in soils under the road sliding downhill. This movement caused a large fissure to form in the roadway that has resulted in both lanes of traffic being unsafe for vehicles. Soils continue to move, causing further damage to the roadway. Over 200 feet of roadway has been impacted. 
“We pledge to work diligently on the repair and communicate regularly  about progress that is made,” stated Yosemite National Park Acting Superintendent Woody Smeck. “We know this road closure places a burden on the surrounding communities and we are working as quickly as we can to get the road reopened safely. We appreciate the Federal Highway Administration’s assistance in expediting this project. We greatly appreciate the patience and support of all communities along the Highway 120 corridor.”
Visitors are still able to visit Yosemite National Park via the Big Oak Flat entrance. Crane Flat and the Merced and Tuolumne Groves of Giant Sequoias are accessible and open. The park has waived the entrance fee for visitors entering the park via Highway 120. Park entrance fees still apply to all visitors entering the park via the Arch Rock and South  Entrance Stations.    
The Wawona Road (Highway 41) is currently open to one-lane controlled traffic.
Highway 140 (El Portal Road) remains open and clear for all vehicular traffic  Visitors traveling on this road are urged to drive with caution and be aware of rocks and debris on the road. 
For updated 24-hour road and weather conditions for Yosemite National Park, please call 209-372-0200, press 1 and press 1 again.  (S. Gediman)
Highway 41 Reopened
Caltrans has reopened Highway 41 between the south boundary and Fish Camp to one-way controlled traffic. Federal Highways contractors are working on the Big Oak Flat Road, but there's no estimated opening date yet. For updated 24-hour road and weather conditions for Yosemite National Park, please call 209-372-0200 and press 1,1.  (M.
