Carbon Sequestration on Surface Mine Lands
Project # 41624

Primary Performing Organization
University of Kentucky

This project will develop planting sites to demonstrate low-compaction surface mine reclamation techniques for carbon sequestration, through the growth and harvesting of high-value trees.  By investigating the potential for reclaimed mine lands to sequester carbon to offset rising levels of greenhouse gas in the atmosphere, particularly carbon dioxide (CO₂), this project will help justify a change in current mine reclamation practices to allow loose dumped material, which encourages forest establishment.

Abandoned and previously reclaimed mine lands in the Appalachian region may provide good locations for expanded terrestrial carbon sequestration by means of reforestation.  Because these areas are devoid of carbon after being mined, the planting of forests can dramatically increase carbon uptake at these sites, thereby increasing carbon accumulation in soils and forest biomass.  See photograph of Mined Land Reclamation site.  To demonstrate the potential for terrestrial carbon sequestration on mined lands, the University of Kentucky, joined by the U.S. Forest Service and the Office of Surface Mining and Reclamation Enforcement, has initiated a reforestation project at several locations in Kentucky.  These sites differ with respect to geology and reclamation practices.  Various methods are being used to decrease physical and chemical limitations on plant growth, such as the use of loose dumped material (low-compaction techniques).   These methods will show whether the establishment of high-value forest species (hardwood and conifers) is possible.

The basic objectives of the project are to:

• Develop concepts combining indirect capture and storage of CO₂, with accompanying reduction of pollutant emissions and associated water quality improvements.
• Demonstrate and verify large-scale carbon sequestration by reforestation of post-mining lands using high value tree species.
