A designation given to those species that are in danger of becoming endangered in the near

A method in
telemetry studies used to
pinpoint where the exact location of an animal is by relying on the intensity of signals at three
different points that form a triangle. The middle point receives the strongest signal.
A stream that flows into or joins a larger stream (for example, Monture Creek is a tributary to
