在过去150年中，中欧大部分地区忽视了传统的森林管理做法，对生物多样性造成了严重后果。在过去，矮林是阔叶林地最重要的经营方式之一。为了调查矮林的影响，我们分析了物种丰富度和密度的矮林林地在法国阿尔萨斯标准的蝴蝶群落。我们采样蝴蝶和环境参数，通过标准化样带行走（n = 37块）在5个不同的演替阶段（第一年，第二年，边缘，灌木和木材阶段）。结果表明，矮林林地的蝶类物种丰富度较高，共36种，其中受威胁的有13种。蝴蝶表现出明显的反应，矮林，每个演替阶段窝藏一个独特的组合。然而，物种丰富度和密度的居民和受威胁的物种是最高的早期和中期的演替阶段（第二年和边缘阶段）和最低的最新的演替阶段（木材）。迁徙物种的模式略有不同。物种丰富度和密度沿着演替梯度下降，从第一年到木材阶段。温暖的小气候条件（所有群体），花蜜资源（迁徙物种）的可用性和足够的寄主植物生长在适当的条件下（居民和受威胁的物种）与较高的密度和更大的多样性的蝴蝶。根据我们的研究结果，维护和扩大矮林管理应该是一个合适的工具，以抵消林地蝴蝶的普遍下降和早期演替物种的损失在林地。(C)2012爱思唯尔有限公司保留所有权利。
During the past 150 years traditional forest management practices have been neglected in most parts of Central Europe with severe consequences for biodiversity. Coppicing has in the past been one of the most important forms of management for broadleaved woodlands. To investigate the effects of coppicing, we analyzed species richness and density of butterfly communities in coppiced woodlands with standards in the French Alsace. We sampled butterflies and environmental parameters through standardized transect walks (n = 37 plots) in five different successional stages (first-year, second-year, fringe, shrub and wood stage). With 36 butterfly species in total, among them 13 threatened species, coppice woodlands had a comparatively high species richness. Butterflies showed a clear response to coppicing, with each successional stage harboring a unique assemblage. However, species richness and densities of resident and threatened species were highest in early and mid-successional stages (second year and fringe stage) and lowest in the latest successional stage (wood). The pattern was slightly different for migratory species. Species richness and densities decreased along the successional gradient from the first-year to the wood stage. Warm microclimatic conditions (all groups), the availability of nectar resources (migratory species) and sufficient host-plants growing under suitable conditions (resident and threatened species) were associated with higher densities and greater diversity of butterflies. Based on our results, maintenance and expansion of coppice management should be a suitable tool to counteract the general decline of woodland butterflies and the loss of early-successional species in woodlands.
