Quick answers

Did wolves recover everywhere?

Global LC hides Mexican wolves, some European growing pains, and US delisting fights. Resilience here is mid-high because many Holarctic populations rebounded -- not because conflict ended.

What happened in Yellowstone in 1995?

Fourteen wolves from Canada were released (more in 1996). Elk behaviour and riparian vegetation became a long argument, not a cartoon instant forest.

Is the trophic cascade settled?

Early popular accounts over-simplified. Later work kept wolves important and added drought, human hunting, and beaver. The cascade is a research programme, not a poster.

Who was Aldo Leopold here?

A forester who had killed wolves and later wrote the mountain-as-ethics essay (1949). The US environmental canon still starts many wolf talks there.

What is Isle Royale?

A closed wolf-moose system studied since 1958. Inbreeding and later genetic rescue (2018-) made it a lab of isolation.

Are wolves more intelligent than big cats in this atlas?

Pack coordination and canine social cognition sit high. Gorillas and elephants still outrank them. Scores are relative, not IQ certificates.

IUCN: Least Concern (global)

Start with this section - Origins & evolution

The gray wolf did not enter English as a finished emblem. Hunts, films, listings and field stations rewrote the animal on a dated clock.

This chapter keeps ten timeline points, five eras and three milestones so a later translation can hold the same years.

Timeline

1890sLobo of Currumpaw

Seton hunt and later story -- a guilt template for US wolf writing.

1926Yellowstone extirpation

Leopold essay that made the wolf an ethics object.

1958Isle Royale study starts

Mech, Jordan, Vucetich later -- moose and wolves as a closed book.

Gray wolves listed; the legal engine of later reintroductions.

1995Yellowstone releases

Canadian wolves in the Northern Range -- a global media return.

1998Mexican wolf releases

Captive-bred C. l. baileyi into Arizona/New Mexico.

2011-20US delisting fights

Great Lakes and Northern Rockies status ping-ponged in courts.

2018Isle Royale rescue

Translocations to address inbreeding after the island population collapsed.

2020sEuropean pack maps

Germany and France treat returning packs as a livestock ministry file.

Bounty centuries

Erase the competitor

Eurasia and North America paid for dead wolves into the 20th century.

1949-73

Ethics then statute

Leopold to the ESA -- a paper trail for return.

1995-98

Reintroduction years

Yellowstone and Mexican wolf releases as twin experiments.

2011-20

Delist and relist

US courts treated wolves as a perpetual motion machine.

2020s

Europe and islands

Pack maps in the EU and genetic rescue on Isle Royale.

Milestones

Leopold essay

1949

A killed wolf as an ethics origin story.

Yellowstone 1995

1995

The return that every later cascade talk cites.

Isle Royale rescue

2018-

A closed study admitted it needed new genes.

Reading gray wolf history beside the resilience score keeps a recovered stock from standing in for a threatened cousin.
