Polar bear in 2008: ESA 2008
[564] [read-polar-bear-6-164] In 2008, the field log for Polar bear is headed “ESA 2008.” The figure kept beside that heading is 2008. It is a count or a date from the work, not a rank of the species’ worth. A zoo birthday card does not replace the log. Ecological role 67/100 -- engineer, keystone, pump or specialist.
A marine bear whose seal-and-ice budget made Churchill, Knut and climate models into one public animal. 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. Western Hudson Bay is an early-ice-loss stock and a tourist town. It is a visible subpopulation, not the whole Arctic.
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. 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.
Keep 2008, “ESA 2008,” and 2008 together or the note on Polar bear stops being that year’s record.2008
