Soil Water Infiltration Rate
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 12 benchmarks together — the OptimalRange form drives the primary score, while 11 guard(s) constrain the result.
Evidence & Context
Based on available research from analogous ecosystems, the proposed benchmark for soil water infiltration rate under best-practice Production Forestry in Australian Tropical Monsoonal Savannas is: Reference Value: A steady-state infiltration rate of >100 mm/hr, with the potential under optimal soil conditions to reach 150−180 mm/hr.
Soil Water Infiltration Rate (SWIR) under best-practice Production Forestry in Australian Tropical Monsoonal Savannas
This benchmark represents the minimum steady-state soil water infiltration rate indicating high environmental health in production forestry within the Tropical Monsoonal Savannas biome of Australia.
This benchmark range is primarily derived from field measurements conducted by Moody and Cong (1998) on Ferrosols in Queensland, a soil type found within Australian savanna landscapes. Their study included sites described as 'virgin savannah woodland,' which are characterized by high soil organic carbon levels and represent a high-health native ecosystem state. The benchmark is an inferred target for production forestry based on analogous native ecosystems.
