The U.S.-Mexico border wall serves as a barrier not only to human migrants but also to diverse wildlife, including jaguars, pumas, and black bears. A study utilized motion-sensing cameras to understand the wall's impact on this ecosystem. Conducted by Ganesh Marín, the study recorded animal activities over two years, capturing significant interactions that reveal the challenges wildlife face. The footage displayed unique coexistence of both tropical and non-tropical species, indicating the ecological richness of the area and the critical need for wildlife movement across the border.
The border wall, a centerpiece of President Donald Trump's agenda, cuts through a rugged, unique ecosystem home to hundreds of native species, from jaguars and pumas to black bears and deer.
For the research, ecologist and lead author Ganesh Marín set up 85 motion-sensing cameras in northeastern Sonora, Mexico, along and south of the U.S. border in Arizona and New Mexico.
Over roughly two years, the cameras captured hundreds of hours of footage, including more than 21,000 clips with mammals, said Marín, a National Geographic Explorer.
Some of the recordings are pretty incredible, such as a young puma making a chirping sound, likely calling for its mother.
