Study finds resident mortality is key driver of grey wolf range dynamics
This scientific research article examines how resident mortality (particularly human-caused deaths) determines grey wolf range dynamics. The study focuses on wolf populations in the Iberian Peninsula and broader European/North American contexts, analyzing how direct persecution, wild prey depletion, and habitat loss affect large carnivore recovery. The research suggests that effective population-level protection is needed for enabling wolf recovery, and that down-listing/de-listing policies should be supported by explicit evaluation of indirect effects on mortality patterns.
Key quotes
Many large carnivore species now persist in only part of their former distributions, following historical eradication efforts across much of their ranges.
Direct persecution, wild prey depletion or habitat loss currently hamper their recovery.
Large carnivores in Europe and North America have remarkably expanded their ranges over the last few decades, including some recoveries into landscapes intensively used by people.
In the Iberian Peninsula, enabling recovery may require effective population-level protection.
Down- and de-listing policies should be supported by explicit evaluation of the indirect effects on mortality.
