In tracking, what does the term "evidence" primarily refer to?

In the context of tracking, the term "evidence" primarily refers to physical proof of presence. This includes any tangible signs that indicate an individual or animal has passed through an area, such as footprints, tire tracks, broken branches, or other notable alterations to the environment. Such physical evidence is essential for SAR teams, as it provides concrete indications of a subject’s path, movements, and location, aiding in the search effort.

While reports and testimonies can provide context and support the search effort, they are not the primary form of evidence used to track someone. Similarly, tools and equipment are important for conducting the search but do not constitute evidence in themselves. Environmental conditions, while relevant to the search operation, do not serve as direct proof of presence. Thus, physical proof remains the cornerstone of effective tracking in search and rescue scenarios.
