The Bureau of Land Management (BLM) is seeking to procure 13 GPS/Iridium radiocollars for caribou, specifically the Vertex Lite-3D model, along with activation and data plan subscriptions. These collars are required to ensure compatibility with existing telemetry equipment used by cooperating agencies, providing essential GPS location fixes, a minimum lifespan of five years, and daily data transmission capabilities, even in extreme temperatures. This procurement is critical for ongoing ecological studies and collaborative management efforts involving the Fortymile Caribou herd, emphasizing the need for continuity in research operations. Interested vendors can contact Laura Sherman at lsherman@blm.gov or by phone at 907-271-4440 for further details.
