Camera traps provide pretty basic information. Biologists use the images to confirm what animals live in a given area. There is photographic proof, along with the date/time stamp, that an animal was in a specific place, at a specific time and on a specific date.
And while any photograph is cool, if it happens to be of an animal that is endangered or difficult to spot, the picture becomes even more valuable.
But while the research is new, the irony is that the use of camera traps really isn’t.
