Human-wildlife conflict
Fatal attractions are a standard movie plotline, but they also occur in nature, with much more serious consequences. As a conservation biologist, I’ve seen them play out in some of Earth’s most remote locations, from the Gobi Desert to the Himalayan Highlands. In these locales, pastoralist communities graze camels, yaks and other livestock across wide ranges of land. The problem is that often these animals’ wild relatives live nearby, and huge, testosterone-driven wild males may try to mate with domestic or tamed relatives. Both animals and people lose in these encounters. Herders who try to protect their domestic stock risk injuries, emotional trauma, economic loss and sometimes death. Wild intruders can be displaced, harassed or killed. These clashes threaten iconic and endangered species, including Tibetan wild yaks, wild two-humped camels and Asia’s forest elephants. If the wild species are protected, herders may be forbidden from chasing or harmin...
Human-wildlife overlap is projected to increase across more than half of all lands around the globe by 2070. The main driver of these changes is human population growth. This is the central finding of our newly published study in the journal Science Advances. Our research suggests that as human population increases, humans and animals will share increasingly crowded landscapes. For example, as more people move into forests and agricultural regions, human-wildlife overlap will increase sharply. It also will increase in urban areas as people move to cities in search of jobs and opportunities. Animals are also moving, mainly in response to climate change, which is shifting their ranges. Across most areas, species richness – the number of unique species present – will decrease as animals follow their preferred climates. But because human population growth is increasing, there still will be more human-wildlife overlap across most lands. We also found areas where human-...
Fishermen across the Gulf of Mexico are reporting that something is eating fish off their lines. What’s to blame? Many recreational anglers point a finger at sharks. This conflict has caught politicians’ attention. Congress has directed the National Oceanic and Atmospheric Administration, which regulates fishing in U.S. waters, to review shark and dolphin interactions with fisheries, and the U.S. House of Representatives recently passed the SHARKED Act, which would create a task force to address the problem. I’ve studied this conflict, which is formally called depredation, for the past decade. While some shark populations in the Gulf of Mexico, such as bull sharks, are increasing, my colleagues and I have found evidence that human perceptions are also an important factor. A Gulf angler races to land a fish before sharks take it. Sharky waters The Gulf of Mexico is home to more than 70 species of sharks – and those...
One of the biggest privileges of being a primatologist is spending time in remote locations with monkeys and apes, living near these animals in their habitats and experiencing their daily lives. As a 21st-century human, I have an immediate impulse to take pictures of these encounters and share them on social media. Social media can help scientists raise awareness of the species we study, promote their conservation and obtain jobs and research funding. However, sharing images of wild animals online can also contribute to illegal animal trafficking and harmful human-wildlife interactions. For endangered or threatened species, this attention can put them at further risk. My research seeks to find ways for scientists and conservationists to harness the power of social media while avoiding its pitfalls. My colleague, ecologist and science communicator Cathryn Freund, and I think we have some answers. In our view, wildlife professionals should never include themselves in pictures wi...
At hundreds of wildlife rehabilitation centers across the U.S., people can learn about wild animals and birds at close range. These sites, which may be run by nonprofits or universities, often feature engaging exhibits, including “ambassador” animals that can’t be released – an owl with a damaged wing, for example, or a fox that was found as a kit and became accustomed to being fed by humans. What’s less visible are the patients – sick and injured wild animals that have been admitted for treatment. Each year, people bring hundreds of thousands of sick and injured wild animals to wildlife rehab centers. Someone may find an injured squirrel on the side of the road or notice a robin in their backyard that can’t fly, and then call the center to pick up an animal in distress. We study ecology and biology, and recently used newly digitized records from wildlife rehabilitation centers to identify the human activities that are most harmful to...
