The news echoed across the world, through internet channels, in newspaper headlines and during TV broadcasts. Roughly 1 million plant and animal species face extinction, according to a multinational study by a United Nations-backed panel. But where are these species concentrated, and which regions are most vulnerable?
A new paper out of UC Santa Barbara’s Bren School of Environmental Science & Management provides an overview of where ocean biodiversity is most at risk, and how that compares with protected areas. The paper, led by doctoral student Casey O’Hara, appears in the journal Conservation Letters. The results present the first comprehensive map of risks to biodiversity in the ocean.
“The idea was to look at the measure of extinction risk at an ecosystem level, and see how it varies across the globe, across all the oceans,” O’Hara said. “And then we asked, ‘How does that compare to where we put marine protections?’”
