Global oyster reefs have faced a massive decline toward functional extinction
In short: Researchers examining oyster reefs across 144 bays and 44 ecoregions found that roughly 85% of these habitats have been lost globally. The study observed that more than 90% of reefs have disappeared from specific bays and 63% from entire ecoregions, with some areas seeing losses of over 99%.
The study compared past and present oyster abundances to highlight the scale of habitat loss driven by resource extraction and coastal degradation. While the findings suggest that cost-effective restoration solutions exist, the research is limited to the specific bays and ecoregions surveyed.
This massive decline threatens both ecological stability and economic value. By identifying that most remaining wild oyster captures are concentrated in just five North American ecoregions, the research emphasizes the vulnerability of remaining populations.
Why it matters: The massive decline of oyster reefs threatens vital ecosystem services and global biodiversity.
