The document is a Single Source Justification for the acquisition of GPS radio collars from Telonics by the U.S. Fish and Wildlife Service (FWS). The justification outlines the necessity of these collars for monitoring grizzly bear populations in Montana, Idaho, and Washington, which supports recovery efforts for endangered species. Due to existing proprietary software and equipment compatibility, Telonics is deemed the only capable supplier, as purchasing from others would incur additional costs and logistical challenges. The FWS has successfully utilized Telonics' products in the past, noting their reliability and effective service, including collar refurbishment that is not available through other suppliers. The contracting officer recommends proceeding with a sole source procurement, asserting that the costs are fair and reasonable since Telonics is uniquely positioned to meet the agency's needs. This document complies with federal regulations under FAR for sole source acquisitions, aiming to maintain efficiency and continuity in wildlife monitoring efforts.
