Evidence & Context

The optimal range can be conceptualized as extending around this benchmark, for instance, from 4.0 to 6.0 mg CO₂-C/kg/day. Values within this range suggest a healthy coupling between plants, animals, and the soil microbial community.

Metric Definition:

Range of microbial respiration rates representing balanced and efficient ecosystem function supporting productive and resilient pasture.

Benchmark Definition:

This range represents the optimal microbial respiration rates indicating healthy ecosystem metabolic balance in arid karstic woodlands and shrublands under grazing.

Justification:

Conceptualized from proxy benchmark and ecological understanding of system resilience and nutrient cycling.

Notes

Reflects a resilient system with robust nutrient cycling balanced by high carbon inputs; respiration rates within this range are considered healthy. No upper detrimental threshold — higher values are always better up to natural saturation. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
