Quick answers
Why is resilience low if some subpopulations look stable?
IUCN VU and the 2008 ESA listing rest on ice-season length. A few stable stocks do not cancel a circumpolar ice forecast. High resilience in this atlas means secure (koi, many owls), not famous.
What did the 2008 US listing change?
It treated greenhouse gases as a listed-species threat. Courts later limited how far that could reach power plants; the biological finding stayed.
Is Churchill typical?
Western Hudson Bay is an early-ice-loss stock and a tourist town. It is a visible subpopulation, not the whole Arctic.
Who was Knut?
A hand-reared Berlin cub (2006-2011) whose fame and death made zoo ethics a tabloid. He is culture, not a sea-ice time series.
Do polar bears eat only seals?
Seals (especially ringed) are the fat that pays. Bird eggs, carrion and land food appear more in long ice-free summers -- a budget problem, not a new niche that replaces ice.
What is Nanook of the North to this file?
The 1922 film staged Inuit life for a southern camera. It is a portrayal, not an ethnography of nanuq knowledge.
IUCN: Vulnerable
The polar bear future is a triad of climate, take and attention -- not a product roadmap.
Risk scores here track conservation pressure relative to other types. High resilience types sit in a calmer band; CR/EN types do not.
Conservation risk
Polar bear sits in a critical pressure band in this atlas (resilience 21/100). Vulnerable. The 2008 US ESA listing treated sea-ice loss as the primary threat -- a climate instrument more than a hunt story.

Safeguards
Listing and enforcement
CITES, ESA, RFMOs and national parks only work when patrols and papers move.
Site protection
A breeding lake, ice type or cavity tree cannot be replaced by a logo.
Prey and forage base
Seals, krill, ungulates, bamboo and sardines are the quiet half of the polar bear budget.
Disease and toxin watch
Ebola, KHV, TTX, lead and rodenticides are type-specific ceilings.
English-language science capacity
The field sites in the techDeep lens still train the next census -- they are a safeguard only if funded.
What monitoring automates first
Census and acoustics
Camera traps, radar and moorings already take hours that used to be only notebooks.
Trade-document checks
eBCD and permit databases can flag a loin or a skin faster than a paper file.
Outbreak mapping
Flu and Ebola desks now run on shared dashboards -- still needing a human closer.
Visitor flow
Ticketing and hide cameras can be scheduled; habituation ethics cannot be fully automated.
Structural shifts
Climate as habitat law
Ice, bleach and river heat are now listing factors, not background weather.
From fortress to corridor
National parks plus gene flow -- panda belts, tiger landscapes, wolf packs on roads.
Fame as a take risk
Nemo, Jaws, Koko and Cecil still move capture, fear and donations in the same year.
English science is not the range
The localLens is a reading aid. Range-state languages still hold the living animal.
Outlook
Near term
Expect more listings, more cameras and more conflict paperwork -- not a sudden best-species ending.
Medium term
Sites that keep forage and enforcement will hold; single-lake and single-forest types stay brittle.
Long view
The polar bear body plan will remain recognisable. The map of secure versus threatened populations will not.

Tiger
Asia largest cat — subspecies maps, 1973 Project Tiger, and roughly 4,000 remaining wild animals still frame a century of recovery arithmetic.
Overall 62 🦁Lion
A social pantherine whose prides, Gir relic and 2015 Cecil killing still structure African conservation politics.
Overall 66 🐘African bush elephant
The atlas type is the bush elephant -- an ecosystem engineer whose ivory ban (1989) and split from forest elephants still structure African conservation.
Overall 61 🐺Gray wolf
A Holarctic pack hunter whose 1995 Yellowstone return and older Leopold ethics still structure predator politics.
Overall 78 🐼Giant panda
A bamboo specialist whose WWF logo, Wolong quake and 2016 IUCN downlist from EN to VU made a recovery into a brand.
Overall 41 🦍Gorilla
The atlas type is the western gorilla -- a knuckle-walking ape whose Fossey-era mountain cousins and Koko lab fame split one public name.
Overall 45 🐋Blue whale
The largest animal whose 1966 IWC protection, 1982 moratorium and still-thin Antarctic recovery define a hunted giant.
