Ecologists challenged a landmark Yellowstone wolf reintroduction study, arguing methodological flaws overstated how much predators reshaped vegetation and river channels.
Critics said early trophic cascade models relied on short observation windows and selective camera trap placement.
Reanalysis incorporating longer climate trends suggested beaver activity and hydrology played larger roles than wolf predation alone.
Conservationists acknowledged nuance while defending wolves’ documented impacts on elk behavior.
Park managers said the debate will not alter current predator protections but may refine monitoring protocols.
Science historians noted the original narrative gained cultural power beyond peer-reviewed certainty.
The dispute illustrates how iconic environmental stories face renewed scrutiny with better datasets.
