Alsophila spinulosa monitoring plot species density species composition height structure DBH structure

Alsophila spinulosa is a rare, endangered plant. For long-term monitoring and research of biodiversity, we established a monitoring plot (area, 2 hm2) in the Huagaoxi National Nature Reserve and investigated species composition, diameter at breast height (DBH), and height structures of trees (H ≥ 3 m). The results showed that the monitoring plot consisted of 3 498 individuals, belonging to 39 families, 56 genera, and 87 species. The importance value indexes of Alsophila spinulosa, Alangium chinense, Alniphyllum fortune, Cunninghamia lanceolata, and Machilus pingii were 22.58%, 8.53%, 8.24%, 6.27%, and 4.63%, respectively. A. spinulosa had an obvious advantage in terms of the population, and the monitoring plot was considered an A. spinulosa community. The maximum, minimum, and average densities in the monitoring plot were 69 individuals/100 m2, 1 individual/100 m2, and 18 individuals/100 m2. The species was abundant in saplings and seedlings, the population could self-regenerate, and the A. spinulosa community could stabilize. A. spinulosa was mainly distributed in the lower and middle layers of trees and was abundant in the seedling banks. At present, the temporary plot is relatively small in size and has been monitored over a relatively short period, which is insufficient to understand the mechanism of biodiversity maintenance at the community level. This study is the first to survey and analyze the species composition, species density, diameter grade structure, and height structure of a 2 hm2 monitoring plot, thus providing an effective theoretical basis for long-term monitoring and research of biodiversity.
