Episode notes
Origins Of The Wolf Revival Story
- Reintroduction of wolves sparked a popular narrative that they caused wide ecosystem recovery across Yellowstone.
- The podcast shows that story originated from early aspen studies and media amplification.
Tree Rings Fueled The Cascade Claim
- Eric Larson's aspen research found tree growth fell after wolves were extirpated in the 1920s.
- His team's later fieldwork showed taller trees in places wolves spent more time, which fueled cascade claims.
Same Data, Different Conclusions
- Re-examining the same aspen data with different metrics produced a patchier picture of recovery.
- Larson's team found mixed aspen outcomes and argued wolves are only one piece of the story.
