油棕的扩张威胁着整个热带地区的生物多样性生态系统。然而，棕榈油是一种广泛使用且有利可图的作物，因此确定减轻油棕扩张对生物多样性影响的战略非常重要。许多国家出于水文原因保护河岸保护区（沿着的森林带），同时也保护油棕榈树中无法存活的物种。然而，河岸带的管理准则已告知相对较少的生态研究。我们评估了如何在沙巴，马来西亚河岸保护区的结构特征和景观背景影响蜣螂社区。我们还测试了使用飞行拦截陷阱来研究沿着线性森林走廊的蜣螂的运动。总体而言，河岸保护区的粪甲虫丰度比砍伐森林地区低54%，但在砍伐森林中观察到的所有物种都在至少一个河岸保护区发现，并且物种丰富度和多样性都随着保护区宽度的增加而增加。距离一大块连续的森林影响蜣螂群落组成，但不物种丰富度，丰度，或功能多样性。周围景观的森林覆盖量提高了河岸保护区内物种的保留率，植被复杂性的增加与更高的功能丰富度和功能分散度相对应。飞行拦截陷阱并没有表明，有净运动的个人出采伐林区进入河岸保护区。30米储备（建议要求储备在沙巴）的物种丰富度只有10%低于采伐森林，但我们的数据表明，河岸保护区至少50 - 80米的物种丰富度和多样性，在附近的采伐森林相等。在制定油棕榈种植园的政策和可持续性准则时，应考虑到这些调查结果，特别是如果它们更广泛地适用于依赖森林的类群，无论是在正在从森林转换的地区还是在需要恢复森林的现有油棕榈种植园。
Oil palm expansion threatens biodiverse ecosystems across the tropics. However, palm oil is a widely used and profitable crop, so identifying strategies that mitigate the impact of oil palm expansion on biodiversity is important. Riparian reserves (strips of forest along rivers) are protected in many countries for hydrological reasons and also support species that would not otherwise persist in oil palm. However, management guidelines for riparian zones have been informed by relatively few ecological studies. We assessed how the structural features and landscape context of riparian reserves in Sabah, Malaysia affected dung beetle communities. We also tested the use of flight intercept traps to study movement of dung beetles along linear forest corridors. Overall, dung beetle abundance in riparian reserves was 54% lower than in logged forest areas, but all species observed in the logged forest were found in at least one riparian reserve site and both species richness and diversity increased with reserve width. Distance from a large block of continuous forest affected dung beetle community composition but not species richness, abundance, or functional diversity. The amount of forest cover in the surrounding landscape improved the retention of species within riparian reserves, and increases in vegetation complexity corresponded with higher functional richness and functional dispersion. The flight intercept traps did not indicate that there is net movement of individuals out of logged forest areas into the riparian reserves. The species richness of 30 m reserves (the suggested requirement of reserves in Sabah) was only 10% lower than in logged forest, but our data indicate that riparian reserves of at least 50 – 80 m are needed for species richness and diversity to equal that in nearby logged forest. These findings, particularly if they apply more widely to forest-dependent taxa, should be taken into account when setting policy and sustainability guidelines for oil palm plantations, both in areas undergoing conversion from forest and in existing oil palm plantations where forest restoration is required.
