保护热带森林是保护生物学中最紧迫的问题之一，因为在过去50年中发生了迅速的森林砍伐。即使在受保护的森林中，新扩大的村庄所产生的人为影响，如收获药用植物、放牧牲畜和森林火灾，也可能导致环境变化，特别是在森林地面上。我们评估了附近居民的日常活动对天然林的人为影响，在12个地块从村庄边界延伸到泰国的天然林。单位土地面积的断面积并没有呈现出明显的趋势，但是，木本植物的物种多样性线性下降到村边界，这造成了损失的个人密度，因为严重下降的小树苗相比，成年树木和大树苗在村庄附近。对树木大小类别的分析表明，在村庄边界附近缺乏小样本。目前的森林似乎受到很好的保护，基于成年树木的树冠，但再生的今天的森林是不可能的，因为失去了幼苗。
The protection of tropical forests is one of the most urgent issues in conservation biology because of the rapid deforestation that has occurred over the last 50 years. Even in protected forests, the anthropogenic effects from newly expanding villages such as harvesting of medicinal plants, pasturing cattle and forest fires can induce environmental modifications, especially on the forest floor. We evaluated the anthropogenic effects of the daily activities of neighboring residents on natural forests in 12 plots extending from the village boundary into a natural forest in Thailand. The basal area per unit land area did not present a significant trend; however, the species diversity of woody plants decreased linearly towards the village boundary, which caused a loss of individual density because of severe declines in small saplings compared with adult trees and large saplings in proximity to the village. An analysis of tree-size categories indicates a lack of small samplings near the village boundary. The current forest appears to be well protected based on the adult tree canopy, but regeneration of the present-day forests is unlikely because of the loss of seedlings.
