Abstract
ABSTRACT Timber harvesting operations are increasingly used to restore sensitive habitats such as longleaf pine (Pinus palustris Mill.) ecosystems. However, logging companies are often functionally limited by operational costs and site-specific productivity potential. By employing a time study, this project quantified the cost and productivity of a two-person logging crew using conventional equipment in a South Carolina southern pine timber harvest used to restore a longleaf pine savanna ecosystem. Our study found that the feller-buncher, grapple skidder, and knuckle-boom loader produced, on average, 60.7, 23.6, and 45.2 tonnes per Productive Machine Hour (PMH), respectively. When the knuckle-boom loader was exclusively loading log trucks, productivity increased to 48.4 tonnes per PMH. Additionally, a machine rate analysis found that the total cost for each machine was 108.83 USD, 122.92 USD, and 121.25 USD per PMH, respectively, with a total per tonne cost of cutting, skidding, and loading amounting to 9.68 USD. Our findings indicate that restoration harvesting conducted in this manner under similar environmental conditions and price points may remain profitable for both landowners and logging companies. Moreover, the limitations of operating with a two-person crew resulted in minimal negative effects for both profitability and productivity, making it a viable option for similar restoration operations.
