Your Favorite Big Mammals Are in Deeper Danger Than You Thought


A report in the journal BioScience recently revealed that some of the world’s most beloved large mammals could disappear forever if action isn’t taken soon to protect their habitats. Threatened megafauna, which typically inspire more public sympathy and concern than similarly endangered species of plants, bacteria, or smaller animals, in this case include bears, rhinos, and gorillas. In the report, titled “Saving the World’ Terrestrial Megafauna,” a global team of conservation scientists laid out issues of particular concern to these animals’ well-being, including vast deforestation, the expansion of land used for livestock and farming, illegal hunting, and rapid human population growth.

“The more I look at the trends facing the world’s largest terrestrial mammals, the more concerned I am we could lose these animals just as science is discovering how important they are to ecosystems and to the services they provide to people,” said William Ripple, an ecology professor at the College of Forestry at Oregon State University and the report’s lead author. “It’s time to really think about conserving them because declines in their numbers and habitats are happening quickly.”

The 43 scientists note that large mammals have widespread impacts on their ecosystems, and affect everything from regulating disease risks for humans and maintaining healthy populations of animals lower down in the food chain, to preventing wildfires and spreading seeds. The experts examined global trends confronting lions, rhinos, wolves, zebras, tigers, elephants, and other animals, concluding that “Most mammalian megafauna face dramatic range contractions and population declines.In fact, 59 percent of the world’s largest carnivores and 60 percent of the world’s largest herbivores are classified as threatened with extinction on the International Union for the Conservation of Nature Red List. This situation is particularly dire in sub-Saharan Africa and Southeast Asia, home to the greatest diversity of extant megafauna.”

The scientists finished the report with a call to action for world leaders: “We must not go quietly into this impoverished future. Rather, we believe it is our collective responsibility, as scientists who study megafauna, to act to prevent their decline. We therefore present a call to the broader international community to join together in conserving the remaining terrestrial megafauna.” Hopefully their voices and research will not fall on dull ears, but will help leaders and the public come together to take measures to save these large creatures, beautiful and vital for our planet’s health.
