Plant and animal tagging methods encompass a range of techniques used to individually mark organisms for identification, tracking, and data collection in ecological and behavioral research. Approaches include physical tags (e.g., ear tags, leg bands, collars, PIT/ RFID tags, satellite or GPS transmitters), chemical or molecular markers (e.g., stable isotopes, genetic tags), and minimally invasive plant markers (e.g., coded tags on stems or branches). Method selection is constrained by species biology, tag retention, effects on fitness and behavior, environmental conditions, and data-resolution requirements, and is typically accompanied by rigorous ethical, welfare, and permitting considerations in wildlife and conservation studies.
Reducing wolves to protect endangered caribou doesn't always deliver the expected results, and the shape of the land may be the deciding factor.
