Nature’s Services for Coastal California
How will climate change and adaptation strategies affect nature’s services and the people that rely on them?
Incorporating Nature’s Services into Climate Adaptation Planning In California• Design and assess strategies • Apply, adapt and revise InVEST models • Inform decision-making • Evaluate • Communicate
