How to Use This Calculator
  1. Enter Study Area Size (km²) — the total area to be surveyed for the target species.
  2. Input Target Species Home Range (km²) from published telemetry studies or local estimates.
  3. Set Detection Probability (0-1) — the probability a camera detects an individual that passes it.
  4. Enter Survey Duration (days) and Target CV (Precision) — a CV of 0.2 or lower is typically adequate for management.
  5. Review Total Cameras Needed and Recommended Spacing (meters) to design your camera grid.
  6. Use these parameters to budget for camera trap equipment, batteries, and field labor for the survey period.
