Anthropogenic activities (e.g., logging, gold-mining, agriculture, and uncontrolled urban expansion) threaten the forests in the southeast of the Peruvian Amazon, one of the most diverse ecosystems worldwide. However, gold-mining generates the most severe impacts on ecosystems and limits its resilience. The natural regeneration of degraded areas in the southeastern Peruvian Amazon have not been studied deeply. The dataset contains floristic inventories of previously uncharacterized or poorly studied secondary forests degraded and abandoned by goldmining activities and an intact forest in the Tres Islas indigenous community, Madre de Dios region, in southeastern Peru. The data presented was obtained from 12 plots (20 m × 60 m) established in three successional forests abandoned by gold mining and an intact forest (without mining impacts), where all trees with a stem diameter at breast height greater than 1 cm were inventoried. To the best of our knowledge, this is the only dataset in the southwest of the Peruvian Amazon that compares the natural colonization after gold-mining and intact forests. This dataset can be useful for long-term study and monitoring of structure and tree diversity in relatively understudied yet important secondary forests after gold-mining abandonment. Also, this dataset could be used to analyze the successional trajectory process of vegetation and the recovery of aboveground biomass. Furthermore, the data could be used to investigate the effects of functional traits and types of mining on vegetation recovery. Hence, understanding the successional processes will help to improve restoration, reforestation, or reclamation strategies for the recovery of degraded lands in the Amazon.
人为活动（如伐木、金矿开采、农业和无节制的城市扩张）威胁着秘鲁亚马逊东南部的森林，该地区是全球生物多样性最为丰富的生态系统之一。然而，金矿开采对生态系统造成的影响最为严重，并限制了其恢复能力。秘鲁亚马逊东南部退化地区的自然再生情况尚未得到深入研究。该数据集包含了以前未被描述或研究不足的、因金矿开采活动而退化和废弃的次生林以及秘鲁东南部马德雷·德迪奥斯地区特雷斯伊斯拉斯土著社区一片未受影响的森林的植物区系清单。所呈现的数据来自于在三片因金矿开采而废弃的演替森林和一片未受影响的森林（无采矿影响）中设立的12个样地（20米×60米），在这些样地中，对所有胸径大于1厘米的树木进行了清查。据我们所知，这是秘鲁亚马逊西南部唯一一个比较金矿开采后自然定植情况与未受影响森林的数据集。该数据集可用于对金矿开采废弃后相对研究不足但很重要的次生林的结构和树木多样性进行长期研究和监测。此外，该数据集可用于分析植被的演替轨迹过程和地上生物量的恢复情况。再者，这些数据可用于研究功能性状和采矿类型对植被恢复的影响。因此，了解演替过程将有助于改进亚马逊退化土地恢复的修复、重新造林或开垦策略。
