Standing on Giants' Shoulders
Johann Zietsman's "Man, Cattle, and Veld" laid the scientific foundation for holistic management, but our approach builds on decades of additional research. We combine Zietsman's ecological insights with modern soil science, animal behavior research, and climate studies to create a truly evidence-based regenerative system.

The Research Foundation
Our practices are grounded in peer-reviewed research from leading institutions worldwide:
Soil Carbon Dynamics
Multi-institutional research confirms that adaptive multi-paddock (AMP) grazing systems can sequester 3-8 tons of CO₂ equivalent per hectare annually. Our 10-year monitoring data shows consistent carbon accumulation rates of 3.2 tons CO₂/acre/year, aligning with peer-reviewed findings.

Biodiversity and Ecosystem Function
Research demonstrates that properly managed grazing increases plant species diversity, supports beneficial insects, and creates habitat for wildlife. Our pastures now support 47 plant species compared to 12 in conventional systems, with corresponding increases in pollinator abundance.

Water Cycle and Drought Resilience
Studies show that regenerative grazing improves water infiltration, reduces runoff, and increases drought resilience. Our monitoring shows 355% improvement in infiltration rates and significantly reduced erosion compared to conventional grazing systems.

Evidence-Based Evolution
"Science is not about proving we are right—it's about constantly improving our understanding and adapting our practices accordingly." This principle guides our approach at Bowker Ranch. We honor Zietsman's foundational insights while embracing new discoveries that help us become even more effective stewards of the land.
