As anti-poaching techniques have improved over the years, poachers have increasingly used technology to evade detection by patrols and park rangers. Now, conservationists are rising to the challenge of the resulting technological arms race with innovations of their own. Over the past few years, researchers and conservationists have worked to develop new technology to detect and track poaching, including mobile apps, sensors, and AI. In an effort to determine which devices, strategies, and technologies are most effective, researchers assessed a suite of new developments that have been deployed or hold promise, in a recent study published in Frontiers in Ecology and Evolution. "There's all these tools out there to try and push back against something that is increasingly well financed, increasingly organized and difficult to combat," said study co-author Drew Cronin, a conservation biologist at the North Carolina Zoo.
