Soil Water Infiltration Rate

AUS-TSW-FOR-SWI General Moderate confidence

Benchmark Value

66.8 mm/hr
Direction: Higher is desirable ↑
Form: Point

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is Point, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Contributing Benchmarks

Evidence & Context

The benchmark values for the "best available condition" are defined as the mean infiltration capacities measured by Archer et al. (2025) in the "woodland" sites. Clay Soil: 66.8 mm⋅h−1.

Metric Definition:

Mean soil water infiltration rate measured by rainfall simulation in well-structured, mature woodland sites.

Benchmark Definition:

Mean infiltration capacity for clay soil under mature woodland in temperate semi-arid shrublands and open woodlands managed for production forestry.

Justification:

These values represent a high state of ecological function, being 2 to 10 times greater than rates in adjacent, simplified grasslands, demonstrating excellent soil structure maintained under best-practice forestry principles.

Notes

The benchmark values represent a healthy, well-structured ecosystem state that balances water capture with nutrient retention. The values are corroborated by other studies highlighting the positive influence of tree cover on water infiltration.
