BHI Score Trend
Annual BHI scores from baseline through Vintage 2025. Baseline established prior to formal enrollment using historical visual survey data and a preliminary eDNA screen. Annual scores reflect full COI/16S/12S metabarcoding plus 30-day acoustic window. Error bars indicate 90% credible interval from sampling replication.
Species Detected via eDNA and Acoustic Survey
