Committing to behavior change: How to prevent dogs from visiting Atlantic Forest remnants?

Abstract

Behavioral interventions have been applied to induce multiple pro‐environmental changes, yet testing their effects on biodiversity conservation is novel. For certain behaviors, a promising tool is changing the context within which people make decisions through nudges. One such behavior is dog restraining to prevent visits to natural areas, a worldwide source of negative impacts on wildlife. In this preliminary study, we experimentally tested the effects of two interventions (i.e., an informative video on conservation and an informative video plus commitment nudge) on changing dog management among rural owners. We then assessed interventions' effects on owners' behavior change (n = 52) and intention to keep the restraining practice in the future (n = 50). Both interventions promoted a momentary change in owners' behavior, but their effect sizes did not differ. Yet, neither treatment increased the owners' intention to maintain the restraining practices. Although nudges alone may not be the most appropriate solution to reduce the severe dog impacts on wildlife, they might be of practical relevance to conservation stakeholders who deal with threats that are not prone to mitigation through more traditional strategies (e.g., command and control).
