Carrie Schloss

Lead Scientist
Climate & Land Use

Carrie is a Lead Scientist in the Climate and Land programs and focuses on conservation planning and climate change resilience planning. She develops innovative approaches to spatial planning to guide policy and conservation outcomes. Carrie also leads statewide assessments on biodiversity, climate vulnerability, resilience, and adaptation.

Before the Conservancy, she contracted with the United States Geological Survey to apply spatial conservation prioritization tools to offset siting for mitigation. She holds a M.S. from the University of Washington where she analyzed the ability for mammals to keep pace with climate change and explored methods for incorporating climate change adaptation and resilience into conservation planning.

What Carrie is working on now:

I am developing a vision for strategic land protection in California to conserve the places biodiversity is already thriving that are more likely to be resilient to climate change. I am leading a climate vulnerability assessment of conserved lands which uses climate projections and data analytics to guide management action planning.  I am also developing a framework to support the implementation of 30x30 in California.
