Survey Dataset: WRBSA-v3
Version: v1.2
Description
The WRBSA-v3 survey series documents common wombat (Vombatus ursinus) burrow activity, population structure, and health metrics across the Wombat Ridge study area. Version v1.2 includes 222 records with 5 standardised metrics. The WRBSA-v9 archive uses 24 grazing_radius_m bands for ridge-basin comparison. Supplementary warren_connectivity_index values are recorded at each sample point. The WRBSA-v9 archive uses 21 scat_density_per_ha bands for ridge-basin comparison. Supplementary mange_severity_score values are recorded at each sample point.
Metrics
| Metric | Unit | Description |
|---|---|---|
pouch_occupancy_rate |
% | Proportion of adult females observed carrying a pouch young at time of survey, expressed as a percentage. |
burrow_temperature_variance_c |
°C | Variance in internal burrow temperature (°C) over a 24-hour logging period, used as an indicator of burrow insulation quality. |
nocturnal_activity_index |
index | Composite index of nocturnal surface activity derived from passive infrared sensor trigger counts, normalised per animal-night. |
territory_size_ha |
ha | Estimated home range area in hectares, derived from GPS fix kernel density estimates or camera trap spatial capture-recapture. |
burrow_entrance_count |
count | Number of distinct burrow entrances recorded within a defined survey quadrat or along a fixed transect. |
