Great question. Microchips aren't tracking devices so they don't help us find wolves or track their activities. So if we were to capture a chipped wolf we could tell that we had captured it before but we wouldn't be able to find it using the chip. I assume that the technology to use a chip for that purpose is out there but it is not currently being used on pets or in wildlife management. I'm not a biologist or scientist so I will check with my team of wolf biologists but if I remember correctly, price was a major concern and they weren't convinced that the technology would provide what they need when tracking wolves.
