A minerotrophic peatland (fen) located on Mont Aigoual (southern France) is investigated for both modern vegetation and fossil pollen. The site is shown to originate around 2300 cal. BP and to have been strongly influenced by agro-pastoral activities. The spread of nitrophilous and not-grazed plant communities, at the expense of hydrophilous ones, characterized the evolution of the site, even during the recent decline of agricultural activities. This study highlights the role of disturbance on the development of the Aigoual peatlands, and their present-day degradation status, and underlines the need of a well-adapted conservatory management.
对位于法国南部艾古阿尔山的一处富营养泥炭地（沼泽）的现代植被和化石花粉进行了调查。该地点显示起源于约公元前2300年，并受到农牧业活动的强烈影响。以嗜水植物群落为代价，嗜氮和未受放牧影响的植物群落的扩散是该地点演变的特征，即使在近期农业活动衰退期间也是如此。这项研究突出了干扰对艾古阿尔泥炭地发育及其当前退化状况的作用，并强调了采取适应性良好的保护管理措施的必要性。
