this year's fawns need to be darted and sedated. it may look dramatic, but it's harmless for the deer. they get a health check and a collar that will help keep them safe. >> i hope that the work that we have been doing contribute to the recovery of this species and the ecosystems in patagonia. we should keep working for that. >> for this new generation of huemuls, life will now be a little safer with cristian and daniel watching over them.
