An Introduction to Carbon Sequestration on Rangelands
Contacts: David Lewis, 707-565-2621 and Steve Quirt 415-499-4204
Co-sponsors: U.C. Cooperative Extension and Marin Resource Conservation District
The threat of global warming and the opportunity to manage carbon with soils has sparked considerable interest in market based compensation of soil carbon sequestration that decreases green house gas emissions. Rangelands managed for livestock production represent the largest land-use footprint globally, accounting for 25 to 35 % of the global soil carbon pool, and may have potential to sequester more.

  • Introduced online soil survey resources,
  • Explained carbon cycles in soil,
  • Described the current state of markets and availability of compensation,
  • Shared preliminary results from recent soil carbon studies across Marin and Sonoma Counties, and
  • Outlined rangeland management that can lead to improvements in pasture condition and ranch viability through improved soil conditions.
