Sierra Nevada Research Institute Roger Bales Director & Professor SNRI programs Sierra Nevada water/forest research SNRI directions

SNRI mission Foster interdisciplinary research in the Sierra Nevada & Central Valley eco-region Facilitate synergistic links between science, the arts, education & natural resource management.

SNRI research within UC Merced $20 M in research grants to SNRI faculty since campus opened 25 faculty from across campus

SNRI research themes Ecology & ecosystem science Air pollution & public health Environmental economics, policy & management Climate & hydrology

Natural Reserve System SNRI is developing infrastructure for research & education in the region SNRI main area of interest for developing new field facilities Map of UC Natural Reserve System

SNRI field facilities & research sites (incl. proposed) Last Chance NRS PSW exp forest UCM station UCM research UC exp forest TPR Aim is to build transects of instrumented sites along gradients of latitude & elevation Link with common cyberinfrastructure for data capture, archiving & serving Fish Camp Wawona NEON SJV SJER KREW SEKI

UCM-SNRI Wawona field station

UCM-SNRI Wolverton field station, Sequoia National Park (under development)

Campus reserve

The Central Valley Current thinking is to develop natural reserve access sites along elevational gradients in Central & southern Sierra Nevada – both Tulare & San Joaquin basins

Southern Sierra Critical Zone Observatory (CZO) UC-USFS research partnership Underlying hypothesis: The distribution of soil moisture controls ecological & (bio)geochemical processes

CZO is located in the Sierra National Forest, near Shaver Lake Wawona Fish Camp CZO CZO is located in the Sierra National Forest, near Shaver Lake Wolverton

Mixed conifer forest dominates the CZO, which crosses the rain-snow transition (5,000-7,000 ft)

Installing soil moisture probes

Snow depth sensors One over each soil pit 6-10 to capture variability

Snowpack loss & water storage Warmer temperatures means shift from snow to rain & earlier melt snowpack annual storage 14 MAF 13.5 MAF 11 MAF Sacramento Valley storage San Joaquin Valley storage Likely loss of 3-5 million acre feet of snowpack storage in coming decades

California’s need for modern, integrated water information system SNRI researchers are building prototype systems

Snow covered area from satellite snow depth Snow covered area from satellite Tuolumne 1-25 26-50 51-75 76-100 % SCA Blend new measurements using advanced information technology for next generation of decision-support systems Merced American River prototype under development, DWR partnership DOY 131 – May 10, 2004

Sustainability as a research umbrella for SNRI & UC Merced Regional issue subject to global influences Core questions intersect with climate change, environmental pollution, public health, resource management, infrastructure & energy issues

Meeting the challenges posed by sustainability will require interactive efforts among disciplines, many of which have not yet recognized the relevance of environmental issues to their main intellectual discourse UC Merced’s Sierra Nevada Research Institute brings disciplines together to address these challenges

Sustainability is the major challenge facing society As a state university, UC Merced has a responsibility to help meet this challenge Regionally, our need to achieve sustainability is paramount Globally, our state must provide the templates for a sustainable future UC Merced’s Sierra Nevada Research Institute is building partnerships & carrying out research to meet those challenges
