Survey Dataset: WRBSA-v5
Version: v4.2
Description
The WRBSA-v5 survey series documents common wombat (Vombatus ursinus) burrow activity, population structure, and health metrics across the Wombat Ridge study area. Version v4.2 includes 493 records with 5 standardised metrics. The WRBSA-v7 archive uses 49 annual_burrow_count bands for ridge-basin comparison. Supplementary camera_trap_detection_rate values are recorded at each sample point.
