Comparing Mechanical Mastication, Herbicide Application, And Prescribed Fire Within An Established Longleaf Pine (Pinus Palustris Mill.) Ecosystem, Brett Moule Aug 2013

Comparing Mechanical Mastication, Herbicide Application, And Prescribed Fire Within An Established Longleaf Pine (Pinus Palustris Mill.) Ecosystem, Brett Moule

All Dissertations

Longleaf pine (Pinus palustris Mill.) forests once dominated the landscape throughout the Southeast and much of its success could be attributed to ecological disturbances such as fire. However, the use of fire as a management tool may be at risk due to a growing human population, negative impacts resulting from smoke production, and the imposition of restrictive federal and state laws, policies, and standards. This study was designed to determine whether alternative silviculture treatments such as herbicide or mechanical mastication can be used as surrogates to prescribed fire. We applied three commonly used silviculture treatments (prescribed burning, mechanical mastication, …


Ecosystem Responses To Fuel Reduction Treatments In Stands Killed By Southern Pine Beetle, Aaron Stottlemyer May 2011

Ecosystem Responses To Fuel Reduction Treatments In Stands Killed By Southern Pine Beetle, Aaron Stottlemyer

All Dissertations

Heavy fuel loads were created by multiple southern pine beetle (Dendroctonus frontalis Ehrh.) outbreaks throughout the southern Piedmont between 1999 and 2002. Prescribed burning and mechanical mastication are proposed to reduce fuel loading in beetle-killed pine (Pinus L. spp.) stands in the upper South Carolina Piedmont, but their ecological impacts are unknown. Prescribed burning reduced fuelbed continuity by consuming litter (Oi) and fine (1- and 10-hr timelag size classes) woody fuels immediately after the treatment. Duff (Oe + Oa) layer thickness also decreased and mineral soil was exposed in some areas. Mastication resulted in a thick, continuous layer of shredded …
