Analysis

The May Ranch Avoided Grassland Conversion Project is a long-running (since 2016) California grassland conservation project with VVB-confirmed additionality and a 50-year crediting period. However, a significant boundary error (869.6 acres included in error, 4,763 credits debited), invasive species encroachment at one site, and a project-specific baseline introduce moderate integrity and claim-safety concerns. All material findings were addressed with corrective actions, and the project maintains a grievance mechanism and FPIC compliance.
