 So what we do for bears is we do what we call hair snare projects, and it's really a capture-mark-recapture study if you kind of simplify it. It's a little more complicated than that, but if you know anything about capture-mark-recapture, you know, you capture an individual or an animal or whatever, and you mark it, and when you recapture it, you know, that gives you a marked part of the population mark.
