雨林退化的一个关键驱动因素是猖獗的商业伐木。减少影响的伐木技术大大减少了对植被和土壤的残余损害，与传统管理的伐木企业相比，它们提高了木材业务的长期经济可行性。因此，RIL在热带地区的应用越来越多，但我们对RIL减少伐木对生物多样性的负面影响的潜力的了解却微乎其微。我们比较RIL对鸟类，落叶蚂蚁，和蜣螂的影响，在婆罗洲的沙巴，第二次伐木旋转，传统的伐木（CL）的影响，以及与主要（未伐木）森林。我们的研究发生在停止伐木后1-8年。RIL与CL森林的物种丰富度和组成是非常相似的每个分类组。两个RIL和CL显着不同的鸟类和蚂蚁的物种组成方面的未采伐的森林（虽然都保留了大量的物种在未采伐的森林），而组成的蜣螂群落之间没有显着差异的森林类型。我们的研究结果表明，在短期内，RIL和CL之间的生物多样性差异不大。然而，生物多样性，从RIL的好处可能会在停止伐木后较长的时间内积累。我们强调严重缺乏调查这种可能性的研究。此外，如果RI L增加了选择性采伐森林的经济价值（例如，通过REDD+，一个联合国项目：减少发展中国家森林砍伐和退化造成的排放），它可以帮助防止它们被转化为农业种植园，这会导致生物多样性的巨大损失。
A key driver of rain forest degradation is rampant commercial logging. Reduced-impact logging (RIL) techniques dramatically reduce residual damage to vegetation and soils, and they enhance the long-term economic viability of timber operations when compared to conventionally managed logging enterprises. Consequently, the application of RIL is increasing across the tropics, yet our knowledge of the potential for RIL also to reduce the negative impacts of logging on biodiversity is minimal. We compare the impacts of RIL on birds, leaf-litter ants, and dung beetles during a second logging rotation in Sabah, Borneo, with the impacts of conventional logging (CL) as well as with primary (unlogged) forest. Our study took place 1-8 years after the cessation of logging. The species richness and composition of RIL vs. CL forests were very similar for each taxonomic group. Both RIL and CL differed significantly from unlogged forests in terms of bird and ant species composition (although both retained a large number of the species found in unlogged forests), whereas the composition of dung beetle communities did not differ significantly among forest types. Our results show little difference in biodiversity between RIL and CL over the short term. However, biodiversity, benefits from RIL may accrue over longer time periods after the cessation of logging. We highlight a severe lack of studies investigating this possibility. Moreover, if RI L increases the economic value of selectively logged forests (e.g., via REDD+, a United Nations program: Reducing Emissions from Deforestation and Forest Degradation in Developing Countries), it could help prevent them from being converted to agricultural plantations, which results in a tremendous loss of biodiversity.
