FRITZ, K. M., S. FULTON, B. R. JOHNSON, C. Barton, J. Jack, D. Word, AND R. A. BURKE. Do post-mining constructed channels replace functional characteristics of headwater streams? Presented at Mid-Atlantic Stream Restoration Conference, Cumberland, MD, November 07 - 08, 2007.
Impact/Purpose:
Compare organic matter breakdown and associated structural factors in natural and constructed channels across a hydrological permanence gradient; test cellulose filters as a surrogate of leaf litter by comparing the breakdown of filters to white oak (Quercus alba) leaves.
Description:
Mountaintop mining and valley fill (MTMVF) is a method of coal mining common in eastern Kentucky and southern West Virginia. Over 1200 miles of stream channel have been buried by MTMVF. Permits for surface coal mining have recognized constructed drainage ditches associated with MTMVF as compensatory mitigation for natural stream loss. A recent court case blocked four MTMVF permits in West Virginia. Contributing to the decision was that industry and regulators do not have evidence that constructed drainage ditches effectively replace the structure and function of natural headwater streams.
