Managed Grazing with
Carbon Monitoring
THS v1.0 - Annex E
Managed Grazing with Carbon Monitoring pairs adaptive rotational grazing management - moving livestock through paddocks on a planned schedule to mimic natural herd movement patterns - with a digital monitoring, reporting, and verification stack: GPS livestock tracking collars, remote sensing pasture biomass estimation, and periodic soil carbon sampling. Well-managed grazing intensity and rest periods allow grassland root systems and soil biology to rebuild organic carbon stocks that continuous, unmanaged grazing typically depletes.
How this pathway works
Grassland and pasture soils hold enormous carbon stocks in root systems and soil organic matter, built up over millennia of grazing by wild herds moving in tight groups and resting land for extended recovery periods before returning. Continuous, unmanaged livestock grazing - animals left on the same pasture indefinitely - tends to overgraze preferred plants, compact soil, and deplete root biomass and soil carbon over time. Managed grazing deliberately restores the rest-and-recovery cycle through planned rotational movement between paddocks, allowing grass root systems to rebuild between grazing events.
Under the Teravent Hybrid Carbon Standard (THS v1.0) Annex E, this pathway is classified as hybrid because verified carbon outcomes depend equally on the biological pasture and soil system and a digital monitoring technology layer - GPS-tracked livestock movement data, satellite or drone-based pasture biomass estimation, and periodic direct soil sampling - that together substitute for the far more labour-intensive manual monitoring historically required for grazing-based carbon projects. Teravent Hybrid Credits (THC) are issued for verified net tonnes of soil organic carbon accumulation, net of full lifecycle project emissions including methane from livestock digestion.
Three methodology variants are approved under Annex E, spanning core rotational grazing management, digitally optimised stocking density, and grassland restoration on degraded land.
THS v1.0 - Annex E
This pathway is governed exclusively by the Teravent Hybrid Carbon Standard (THS v1.0). No external registry, standard, or methodology is referenced or incorporated.
Three approved methodology variants
THS v1.0 Annex E approves three discrete methodology types, differentiated by the specific grazing management approach and level of digital monitoring integration.
Pastures are subdivided into multiple paddocks using temporary or permanent fencing, with livestock moved on a planned rotation calibrated to forage growth rate and desired rest period. This is the foundational managed grazing methodology, applicable to most temperate and tropical grassland systems, and typically the entry point for producers transitioning from continuous grazing.
- Paddock rotation schedule and stocking density logged per grazing event
- Soil organic carbon sampled at baseline and each verification, standard depth increments (0–30 cm minimum)
- Satellite-derived NDVI or pasture biomass index tracked to corroborate grazing management effectiveness
- Livestock methane emissions estimated per head using standard enteric fermentation factors, deducted from net credit
- Soil compaction and bare ground cover assessed as management quality indicators
GPS-enabled livestock collars track individual animal location and movement patterns in real time, paired with automated pasture biomass sensing (satellite, drone, or ground-based sensors) to dynamically adjust stocking density and paddock rotation timing. This methodology represents the most technology-intensive managed grazing approach, delivering the tightest match between forage availability and grazing pressure.
- GPS livestock movement and dwell-time data logged continuously across a representative sample of the herd
- Automated pasture biomass sensing (satellite, drone, or ground sensor) feeding stocking density decisions
- Soil organic carbon sampled at baseline and each verification
- Livestock methane emissions estimated per head, deducted from net credit
- System uptime and data completeness logged, since gaps in digital monitoring affect MRV confidence
Degraded grassland - from historical overgrazing, erosion, or vegetation loss - often shows the largest potential soil carbon gains once managed grazing is introduced, since baseline carbon stocks are depleted relative to a healthy reference state. This methodology combines managed grazing with active restoration inputs (native seeding, erosion control) and requires continuous digital monitoring given the more dynamic vegetation and soil conditions typical of a recovering system.
- Vegetative cover and bare ground percentage tracked via continuous satellite monitoring
- Soil organic carbon sampled at increased frequency relative to established grassland, given faster recovery dynamics
- Restoration input documentation (native seed mix, erosion control structures) where applied
- Comparison against a regional reference healthy grassland benchmark to contextualise recovery trajectory
- Livestock methane emissions estimated per head, deducted from net credit
Which emission sources must be counted
THS v1.0 Module 3 requires a dual-component accounting boundary spanning the biological pasture/soil system and the digital monitoring technology layer, with a full lifecycle GHG emissions inventory deducted from gross soil carbon accumulation.
Measurement, reporting
& verification
Teravent's Science Advisory Board assesses each pathway against four MRV dimensions. Digital MRV integration gives this pathway relatively high confidence for a soil-carbon-based system, though inherent variability in grassland soil carbon still places overall permanence confidence below engineered mineral pathways.
Grazing management is documented through GPS livestock tracking (MGR-M02) or logged paddock rotation schedules (MGR-M01, MGR-M03), providing very high confidence in the practice change itself. Soil organic carbon is quantified through standard-depth soil sampling (typically 0–30 cm) at baseline and each verification, at a sampling density calibrated to field heterogeneity, cross-validated against satellite-derived vegetation indices tracking pasture biomass and cover as a corroborating indicator between direct soil sampling events. All soil analyses must be conducted by an accredited laboratory using a consistent methodology across the crediting period to ensure comparability.
Demonstrating additionality
THS v1.0 Module 2 requires a three-layer baseline: a biological baseline (the ranch's historical grazing practice), a technology baseline (common practice for digital grazing monitoring), and a combined system net baseline.
Leakage types & deductions
THS v1.0 Module 3 defines three leakage types applicable across all hybrid pathways. Managed Grazing is primarily subject to production-shifting leakage where reduced local stocking density displaces livestock elsewhere.
Buffer pool & NPRR assessment
All Annex E credits carry Class I Biological permanence, the most reversible durability class in the Teravent system, reflecting soil organic carbon's ongoing susceptibility to management change, drought, and disturbance.
| Methodology | NPRR Rating | Buffer Pool Rate | Primary Reversal Risks |
|---|---|---|---|
| MGR-M01 Rotational Grazing | Medium | 20–35% | Management discontinuation; drought; return to continuous grazing |
| MGR-M02 Digital Tracking | Low–Medium | 20–30% | Technology failure/discontinuation reducing monitoring confidence; management reversal |
| MGR-M03 Grassland Restoration | Medium–High | 25–40% | Degraded baseline recovery reversibility; drought sensitivity of recovering vegetation |
Key registration criteria
Projects must meet all of the following minimum requirements to qualify for registration under THS Annex E.
Sustainable Development
Goal alignment
All Teravent registered Managed Grazing projects must complete an SDG impact assessment at registration and at each verification period.
Deployment scope: Global grazing regions - most active in North America, Australia, Sub-Saharan Africa, and South America, wherever ranching operations can support paddock subdivision and digital monitoring infrastructure.
