Small-Woodlot Management by Single-Tree Selection: 21-Year Results
Abstract:In 1958, a case study was established to determine the economic benefits and improvements in quality that could be attained in a previously unmanaged stand of northern hardwoods by using the single-tree selection system. The average net earnings realized per man-hour from three harvests on a 55-acre woodlot, in 1982 dollars, were $7.82, $11.95, and $16.33, respectively. Annual growth of sawlog residuals increased from 119 to 138 board feet per acre. The initial cull of 25% in sawlog trees was reduced to 12%. Board foot volume of growing stock increased by 83% in grade 1 and 3.5% in grade 2 trees, but decreased 8.1% in grade 3 trees. Study results indicate that many unmanaged woodlots have the potential for producing revenue, while allowing the owner to manage for esthetic and multiple-use objectives at the same time. North. J.
