MAIN OBJECTIVES
1. Provide a framework for finer-scale, indicator-focused climate change assessments
2. Provide a case example that compares perceived impacts and observed indicators of climate change
3. Understand the differences between types of climate change indicators & how they can be classified by their utility for climate assessments
Objectives - Methods - Results - Conclusions - Outreach 3
INTERDISCIPLINARY METHODS
1. Graduate-student led with input from faculty advisors
2. Conducted stakeholder survey of perceived CC impacts
3. Identified biophysical data sources and CC indicators
4. Created a final interdisciplinary synthesis and translation of findings for general audience

BIOPHYSICAL CHANGES: OUR INDICATORS FRAMEWORK...
“Climate Change Indicators” defined as: Observed climate-related trends in variables from
physical, ecological, and social systems
Objectives - Methods - Results - Conclusions - Outreach 5
SOCIAL PERCEPTIONS:OUR SURVEY FRAMEWORK…
• What is most important and useful?– Impacts (outcomes) of climate change– Indicators of change
• Exploratory survey (N= 100)– Managers asked about personal and professional
significance

CLIMATE CHANGE INDICATORS IDENTIFIED • Temperature
– Average annual temperature– Frost-free growing season
• Precipitation– Precipitation phase– Snowpack accumulation and
melt– Precipitation intensity
• Water Systems– Streamflow
• Annual discharge• Timing of peak and 50% flow
– Stream temperature
• Ecological Indicators– Phenology
• Lilac blooms• Mountain Bluebird nesting dates
(state bird!)• Salmon migration
– Disturbance• Wildfire• Bark beetle kill
– Species viability and productivity
• Sagebrush
• Social Indicators– Heat related illness– Recreation
• Ski season
