Rising Tide · Species Recovery
Species by species,
the tide is turning.
These are the species that came back, not because an entire ecosystem closed to extraction, but because someone decided one population was worth saving: a hunting ban, a protected rookery, decades of dedicated science. Each story below documents what changed, by how much, and where the numbers come from.
Rising Tide is one of four ways we group ocean recovery stories. This one means a single species pulled back from the edge - through hunting bans, habitat protection, and decades of dedicated science.
Numbered for reference only, no ranking implied. Sources are listed at the bottom of each story.
