dc.description.abstractLogging is a fundamental component of forest management, facilitating the establishment of new stands through the removal of mature trees. However, logging operations often induce substantial soil disturbances, which may adversely affect the growth of second-generation stands. This study aimed to assess the impact of logging on the growth of second-generation Pinus patula stands at Sao Hill Plantation, Tanzania (SHFP), specifically focusing on the impacts of logging on stand growth and forest soil. Six compartments, three from each generation, representing stand ages of 1, 3, and 6 years, totaling 180 systematically sampled plots, each measuring 20 x 20 meters. First- and second-generation stands were treated as experimental groups. An independent t-test was used to analyze the impact of logging on stand growth across generations. Stand growth parameters including the number of stems, tree height, and diameter at breast height (DBH) decreased by 6.5% to 12.3% in secondgeneration stands compared to firstgeneration stands. Soil bulk density in second-generation stand increased by 25.7% and 26.2% in the top 10 cm and 20 cm of soil, respectively, compared to the firstgeneration stand. The findings emphasize the critical role of adopting reduced-impact logging techniques to minimize soil compaction, thereby supporting the longterm productivity.
