Abstract:
A vast silvicultural experiment was set up in 1982 nearby the town of M\'Baïki in the Central African Republic to monitor the recovery of tropical forests after disturbance. The M\'Baïki experiment consists of ten 4-ha Permanent Sample Plots (PSPs) that were assigned to three silvicultural treatments in 1986 according to a random block design. In each plot, all trees with a girth at breast height greater than 30 cm were spatially located, numbered, measured, and determined botanically. Girth, mortality and newly recruited trees, were monitored almost annually over the 1982-2022 period with inventory campaigns for 35 years. The data were earlier used to fit growth and population models, to study the species composition dynamics, and the effect of silvicultural treatments on tree diversity and aboveground biomass. Here, we present new information on the forest stand structure dynamics and tree demography. The data released from this paper cover the three control plots and constitute a major contribution for further studies about the biodiversity of intact tropical forests.
摘要:
1982年,在中非共和国M\'Baiki镇附近进行了大规模的造林实验,以监测扰动后热带森林的恢复情况。M\'Baiki实验由十个4公顷的永久样本图(PSP)组成,根据随机块设计,这些样本在1986年被分配给三个造林处理。在每个情节中,胸围大于30厘米的所有树木都在空间上定位,编号,测量,并在植物学上确定。周长,死亡率和新招募的树木,在1982年至2022年期间,几乎每年都进行监测,为期35年的库存活动。这些数据较早被用于拟合增长和人口模型,为了研究物种组成动态,以及造林处理对树木多样性和地上生物量的影响。这里,我们提供了有关林分结构动态和树木人口统计的新信息。本文发布的数据涵盖了三个控制区,为进一步研究完整的热带森林的生物多样性做出了重大贡献。
