Woody stem composition and diameter at Natchez Trace State Forest

Natchez Trace State Park (NTSP) is in west-central Tennessee, part of the East Gulf Coastal Plain. The forest is composed of hardwoods and Pinus taeda. NTSP was impacted by a 1999 downburst; most of the damaged forest was salvaged by 2001. In 2001, 23 30x30m plots were established (15 salvaged, 8 unsalvaged) to characterize tree species and cm DBH for individuals ≥ 5 cm and sapling densities measured. Pre-disturbance composition was reconstructed from stumps in 2001. Tree sampling was repeated in 2020. Detailed information on sampling can be found in C.A. Oldfield and C.J. Peterson. 2021.

Oldfield）与C.J. 彼得森（C.J. Peterson）2021年发表于《Forests》期刊的论文《风倒与灾后采伐19年后的地上生物量与碳积累》。
