Human-wildlife conflict
Hunting large carnivores is a contentious issue in wildlife management and conservation. It’s on the ballot in fall 2024 in Colorado, where voters will consider Proposition 127, a proposed ban on hunting and trapping of mountain lions, bobcats and lynx in the state. Wildlife agencies often use regulated hunting as a tool for controlling carnivore populations, reducing their impacts on vulnerable wildlife or minimizing the risk of conflict between carnivores and people, pets and livestock. But scientific studies have questioned how effectively recreational hunting achieves these goals. And public attitudes are shifting as participation in hunting declines. We direct Colorado State University’s Center for Human-Carnivore Coexistence and Animal-Human Policy Center. Together with our colleague Benjamin Ghasemi, we recently surveyed Colorado residents about their perceptions of hunting mountain lions and black bears in the state. We found that support for hunting depen...
For anyone who enjoys nature, summer is a fascinating time to be outside. Animals are on the move: Turtles are nesting, baby birds are testing their wings, snakes are foraging and young mammals are emerging. In central Pennsylvania, where I live, last year’s hatchling painted turtles have overwintered in their nests and emerged looking like tiny helpless snacks for raccoons and ravens. I’ve already rescued a baby killdeer – a shorebird that nests in parking lots – that ran off the road and got stuck in a grate. And I’ve watched an eastern chipmunk prey on a nest of towhee chicks. I moved the killdeer to safety because it had fallen into what we call an “ecological trap.” Humans create these traps when we degrade habitat that looks suitable to animals. For killdeer, parking pads and roofs give off all the vibes of a great nesting site – except for the drains – and they have less natural habitat available these days. But I d...
Despite their iconic status and long association with humans, Asian elephants are one of the most endangered large mammals. Believed to number between 45,000 and 50,000 individuals worldwide, they are at risk throughout Asia due to human activities such as deforestation, mining, dam building and road construction, which have damaged numerous ecosystems. My colleagues and I wanted to know when human actions started to fragment wildlife habitats and populations to the degree seen today. We quantified these impacts by considering them through the needs of this species. In a newly published study, we examined the centuries-long history of Asian landscapes that once were suitable elephant habitat and often were managed by local communities prior to the colonial era. In our view, understanding this history and restoring some of these relationships may be the key to living with elephants and other large wild animals in the future. Although e...
From sports to pop culture, there are few themes more appealing than a good comeback. They happen in nature, too. Even with the Earth losing species at a historic rate, some animals have defied the trend toward extinction and started refilling their old ecological niches. I’m a philosopher based in Montana and specialize in environmental ethics. For my new book, “Tenacious Beasts: Wildlife Recoveries That Change How We Think About Animals,” I spent three years looking at wildlife comebacks across North America and Europe and considering the lessons they offer. In every case, whether the returnee is a bison, humpback whale, beaver, salmon, sea otter or wolf, the recovery has created an opportunity for humans to profoundly rethink how we live with these animals. One place to see the rethink in action is Colorado, where voters approved a ballot measure in 2020 mandating the reintroduction of gray wolves west of the Continental Divide. Colorado’s Parks and W...
A biodiversity crisis is reducing the variety of life on Earth. Under pressure from land and water pollution, development, overhunting, poaching, climate change and species invasions, approximately 1 million plant and animal species are at risk of extinction. One ambitious proposal for stemming these losses is the international initiative known as 30x30: conserving and protecting at least 30% of Earth’s surface, on land and at sea, by 2030. Currently, 112 countries support this initiative, including the United States. More nations may announce their support at the international biodiversity conference that opens Dec. 7, 2022, in Montreal. Scientists say that protecting 30% of Earth’s surface will help species and ecosystems recover from the stresses that are depleting them. It also will conserve valuable services that nature provides to humans, such as buffering coasts from storms and filtering drinking water. Protecting forests and grasslands can help slow climate...
