Wildlife
The animals on the edge, and the honest distance between how we count them and how many are really left.
A species is easy to love and hard to count. The gap between the two is where most of the story lives: the difference between a vaquita seen and a vaquita alive, between a downlisting on paper and a recovery in the water, between the animals we choose to film and the invertebrates that are three-quarters of known life on Earth and almost none of the screen time.
These are dispatches on wild species and the instruments we judge them by, Red List categories, survey methods, calving counts, reported precisely, because a number repeated carelessly can do as much damage as no number at all.

A Living Ark: The Wildlife Gamble on Necker Island
Richard Branson's private island doubles as an ark, reintroduced flamingos, Aldabra giant tortoises, an iguana bred as insurance against extinction, and the free-ranging lemurs that split the conservation world. It is also a clean-energy and ocean-protection testbed. The wildlife ambition is real; so are the hard questions about it.
Read →Twenty-Three Calves: The Best Right Whale Season in Seventeen Years, and Why That Isn't Recovery
The 2026 calving season produced more North Atlantic right whale calves than any year since 2009. With roughly 384 animals left, the arithmetic of what twenty-three births actually buys is worth doing carefully.
Read →The Green Sea Turtle Went From Endangered to Least Concern. It Skipped Two Categories On the Way.
After fifty years of protection, the global green turtle population is up 28% and off the threatened list entirely, the first endangered marine turtle ever to make that jump. The label is global. The turtles are not.
Read →Between Seven and Ten Vaquitas Were Seen in 2025. That Is Not the Same as How Many Exist.
The world's most endangered marine mammal was observed, with calves, and did not crash. Every one of those statements is carefully bounded, and the difference between 'observed' and 'estimated' is the whole discipline of counting an animal this rare.
Read →Scientists Mapped the Genome of an Animal Nobody Has Seen Alive Since 2013
The saola, the "Asian unicorn," has not been confirmed alive in more than a decade. In 2025 researchers sequenced its genome anyway, and found a slim, strange reason for hope.
Read →The Monarch Isn't Rare. Its Migration Is Collapsing, and the US Moved to List It.
In December 2024 the Fish and Wildlife Service proposed protecting one of the most common, widespread butterflies in North America. The thing at risk is not the insect. It is the journey.
Read →From 62 Breeding Cats to 648: The Iberian Lynx Recovery, and Why It Isn't Over
The world's most endangered cat was downlisted from Endangered to Vulnerable in 2024, the largest recovery of any cat species on record. It is also a recovery on life support, and the number to watch is not the one in the headlines.
Read →Invertebrates Are 75% of Known Species and 18% of Screen Time. We Are Part of the Problem.
A Cambridge study of a century of nature documentaries found vertebrates take 81% of mentions while making up 3.4% of described species. Conservation science shows the same skew. Any platform that pays creators per view will reward exactly this bias, including, one day, ours.

- IUCN Red List of Threatened Species ↗
The categories our species reporting refers back to.
- IPBES, the science-policy platform on biodiversity ↗
Key terms
- IUCN Red List
- The global inventory that classifies species from Least Concern to Extinct, based on population size, trend, and range.
- Downlisting
- Moving a species to a lower-threat Red List category, sometimes a sign of recovery, sometimes just of better data.
- Bycatch
- Non-target animals caught incidentally in fishing gear, a leading driver of decline for species such as the vaquita.
