eDNA vs camera traps vs acoustic monitoring: biodiversity survey methods compared
eDNA detects 2–10x more species than traditional surveys at $50–200 per sample, camera traps cost $200–600 per unit with 80–95% detection rates for mammals, and acoustic sensors monitor 24/7 at $150–1,000 per device. This guide compares accuracy, cost, taxonomic coverage, and scalability.
