Approach: An Integrated Assessment Framework

Approach: An Integrated Assessment Framework

1. Rapid regional assessment of climate exposure (Girvetz et al. PLoS One)

Identify observed physical & ecological impacts Analyze recent & future climate exposure

2. Determine implications for conservation priorities (Enquist et al. in review)

Evaluate exposure relative to ‘surrogates of sensitivity’

Develop ‘hypotheses of vulnerability’ Prioritize action at regional level

3. Landscape-scale conservation adaptation planning (Cross et al. in review)

Identifying adaptation options in high priority landscapes

Identify observed physical impactsIdentify observed physical impacts

1. Identify climate-linked physical changes in the West:

• Increased aridity• More rain than snow• Declines in snowpack• Changes in the timing

of peak stream flows

2. Look for evidence of this across the state:

Declines in snowpack (green dots)

Adaptation for Conservation Targets (ACT) FrameworkAdaptation for Conservation Targets (ACT) Framework

• Identification of adaptation strategies: – local managers & scientists worked

together to break down uncertainty paralysis.

• Transparent process:– Assumptions and logic documented,

justifying specific actions.

• Identified future information/research needs.

• Provided impetus for landscape management:– collaboration and continued dialogue via

formation of informal CC learning network.

Closing remarks & current researchClosing remarks & current research

How do we track the fingerprints of climate change impacts? V= (E + S – AC)

Vulnerability assessment needs to be a dynamic process

“Phenology…is perhaps the simplest process in which to track changes in the ecology of species in response to climate change.” (Intergovernmental Panel on Climate Change 2007)
