Indiana University research shows preference for non-lethal protection of species
BLOOMINGTON, Ind. — Americans believe endangered species are best protected when their habitats are protected and not when animal predators are killed, according to new Indiana University research.
With the exception of one case involving spiders and frogs, a scientific survey with more than 1,000 participants found overwhelming support for policies that protect habitats and little acceptance of either lethal control or no government action at all.
Professor Shahzeen Attari of the Indiana University School of Public and Environmental Affairs said the study sought to understand evolving public preferences for conservation by answering these questions: “How do we want to intervene to protect endangered species when faced with biological invasions or declining populations? Should we protect habitats, or lethally control predatory species that threaten the endangered species? Should we just step aside and let nature take its course?”
To measure support for various strategies, the researchers pitted one species against another in simplified but realistic scenarios. The cases, drawn from real debates about conservation policy, pit a rare or economically valued species against its more common competitor or predator species:
- Spotted owls versus barred owls
- Salmon versus California sea lions
- Caribou versus gray wolves
- Kirtland’s warblers versus brown-headed cowbirds
- Happy-face spiders versus coqui frogs
Overwhelmingly, survey participants preferred habitat protection over lethal control, both lethal control and habitat protection, or no action. Of all the demographic groups, only older, conservative men were more likely to endorse no action.
