Survey Dataset: WRBSA-v4
Version: v1.2
Description
The WRBSA-v4 survey series documents common wombat (Vombatus ursinus) burrow activity, population structure, and health metrics across the Wombat Ridge study area. Version v1.2 includes 91 records with 5 standardised metrics. The WRBSA-v4 archive uses 44 inter_burrow_distance_m bands for ridge-basin comparison. Supplementary estimated_body_mass_kg values are recorded at each sample point.
Metrics
| Metric | Unit | Description |
|---|---|---|
scat_density_per_ha |
per ha | Number of fresh and semi-fresh scat deposits recorded per hectare along standardised transect surveys. |
track_pad_index |
index | Composite index of footprint and runway signs recorded at sand pad stations, standardised per 100 m of transect. |
inter_burrow_distance_m |
m | Mean straight-line distance between adjacent active burrow entrances within a mapped warren system. |
grazing_radius_m |
m | Maximum foraging distance from the primary burrow entrance, estimated from GPS collar fixes or camera trap detections. |
burrow_depth_cm |
cm | Mean depth of active burrow system from entrance to deepest recorded point, measured using a flexible depth probe. |
