. We analyze open access harvesting of a predator species, while allowing for ecological interaction with herbivore species (the prey). In contrast to existing studies, we find that under some conditions open access harvesting may contribute to the abundance of predator and prey species. Particularly in fragmented habitats, moderate harvesting intensity may be a low‐cost substitute for management, and measures to reduce harvesting may result in collapse of predator and prey stock. These results highlight the importance of analyzing the ecological underpinnings of systems when manipulating economic parameters to promote conservation.
