Briefings

A Norwegian University of Life Sciences study published in BioScience demonstrates Capture-Free Telemetry (CFT), allowing GPS collars to attach to free-roaming terrestrial wildlife without human capture. The proof-of-concept study shows the technique works by placing devices on animals interacting with baited units in their natural habitat. This method aims to reduce the need for catching animals for research, though the study remains a proof-of-concept with limited field data.

Key points

• A proof-of-concept study published in BioScience by the Norwegian University of Life Sciences (NMBU) demonstrates Capture-Free Telemetry (CFT) for wildlife tracking.
• The technique allows GPS collars to attach to free-roaming terrestrial wildlife by placing them on animals interacting with baited deployment units in their natural habitat.

Context

Wildlife researchers have historically needed to catch animals to attach tracking devices, a process that is often difficult and ethically challenging. This new approach, developed at NMBU, offers a potential solution by enabling autonomous deployment of tracking devices on free-roaming animals.

Limitations

The evidence is limited to a proof-of-concept study published in 2026. No long-term field data, animal survival rates, or specific geographic locations are provided. The study does not confirm the technique works reliably in diverse wild environments or without human intervention.
