Human-Wildlife Conflicts

We work with agencies across the globe to identify causes of conflict and develop strategies that promote human-wildlife coexistence.


Aviation Risk: Understanding Vulture Roost Dynamics

Between 1990 and 2007, vulture collisions with civil aircraft in the United States caused more than nine million dollars in damage. Despite the increasing prevalence of both vulture species, there remain unresolved questions regarding basic aspects of their biology and ecology. We are using wildlife cameras to monitor vulture use of manmade structures, such as cell phone towers for roosting, and collecting pellets from underneath roosts to analyze diet. This knowledge will inform management strategies to reduce risk to military aviation and other affected stakeholders.

Investigating human-brown bear interactions in Iran

Wherever humans and animal species share the landscape, interactions between the two are inevitable. Interactions between humans and large carnivore species, in particular, have the potential to result in injury or death of both humans and animals. In Iran, brown bears (Ursus arctos) primarily occur in the Zagros Mountains and the Alborz Mountains regions. We investigated 14 years of human-brown bear interaction data published Iranian government to provide suggestions on possible human-bear conflict mitigation strategies. Our analysis revealed the majority of human-cause mortality to brown bears resulted from illegal shooting and over 90% of bear attacks on humans resulted in injury rather than death.
