Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Urgency to save species from extinction has prompted increased investment in law enforcement in protected areas. To date, such law enforcement has largely focused on increasing costs and reducing opportunities for offending. However, these resource‐intensive approaches are not always effective and can contribute to conflict between people and ...
