Ranchers and conservationists have long been at odds over how to manage the populations of predators at the top of the food chain. Now that wolves have been recently delisted from the Federal Endangered Species Act, state governments in Idaho, Montana, and Wyoming are wasting no time organizing hunts to reduce the animals' numbers, citing increased attacks on cattle as the reason for the culls. Conservationists are planning to respond with lawsuits against the federal government to attempt to bring the wolves back on the endangered list.

Researchers use a range of digital technologies in the field to study animal populations. GPS collars and tags track range and migration; motion-sensitive cameras snap candid photos; pre-recorded calls and songs attract individuals so the scientists can get a closer look. Now a new tool has been added to the field arsenal for University of Montana biologists studying wolves in Idaho: the Howlbox.
