Abstract

Investigations of hydrologic responses resulting from reducing vegetation density are fairly common throughout the Eastern United States. Although most studies have focused on the potential for increasing water yields or documenting effects from intensive practices that far exceed what would be done for fuel-reduction objectives, data from some less-intensive manipulations—such as thinnings, understory removals, and controlled burns for seedbed establishment—that are more easily related to fuel-reduction activities are available. In this chapter, findings from the entire range of available manipulation intensities are presented so that results can be applied to various levels of fuel reductions. Even though site preparation is a silvicultural technique and is not traditionally considered in the context of fuels reduction, activities such as shearing, roller chopping, and windrowing are included in this review because they affect the architecture, mineralization rates, and surface area of materials left onsite, and thus, have relevance to combustibility and fuels management.
