d. indirect observation

Indirect methods (counts of tracks, scat, nests, calls, etc.) estimate population size without capturing, handling, or otherwise disturbing animals, so they are the least invasive. Mark/recapture requires capture/handling; direct observation and sampling can disturb animals or habitat.
