Studying the legacies of past human-environment interactions is essential for understanding current landscape and biodiversity patterns. Human influences on past terrestrial and aquatic vegetation are reconstructed based on palynological analysis conducted on a sediment core from Lago di Vedana (Province of Belluno, Northern Italy). This study represents the first pollen record from the Dolomitic lowlands with varying anthropogenic influences throughout the last 700 years. The radiocarbon-dated pollen record begins ca. A.D. 1300 with semi-open forest and moderate human impact, possibly due to activities of the nearby hospice of San Gottardo. Human impact increased with the foundation of the Vedana Charterhouse in the immediate catchment of the lake in A.D. 1457. Activities of the monks involved extensive forest clearing, cultivation of Cannabis/Humulus and possibly hemp retting. In the 19th century the composition of cultivated species changed following the transformation of the Charterhouse into a farm. The 20th century is characterized by expansion of forest taxa and a distinct decline of human influences, probably due to a rural exodus and abandonment of agricultural activities. Vegetation development at Lago di Vedana is consistent with general trends in the Italian Alps and reveals local cultivation practices. The results illustrate the close intertwinement of climatic trends and local human influences, modulated by regional socio-cultural developments during the last millennium.

过去七个世纪人类对韦达纳湖(意大利北部多洛米蒂山)植被的影响

研究过去人类与环境相互作用的遗产对于了解当前的景观和生物多样性模式至关重要。根据对韦达纳湖(意大利北部贝卢诺省)沉积物岩心进行的孢粉学分析,重建了人类对过去陆地和水生植被的影响。这项研究代表了过去 700 年来多洛米蒂低地受不同人为影响的第一份花粉记录。放射性碳测年的花粉记录开始于大约。公元 1300 年,有半开放森林,人类影响中等,可能是由于附近圣戈塔多临终关怀中心的活动所致。公元 1457 年,随着维达纳修道院 (Vedana Charterhouse) 在湖边集水区的建立,人类的影响也随之增加。僧侣们的活动涉及广泛的森林砍伐、种植作物大麻/葎草和可能的大麻沤制。19世纪,查特豪斯庄园改造成农场后,栽培物种的组成发生了变化。20世纪的特点是森林类群的扩张和人类影响的明显下降,这可能是由于农村人口外流和农业活动的放弃。韦达纳湖的植被发育与意大利阿尔卑斯山的总体趋势一致,并揭示了当地的耕作方式。结果表明,气候趋势与当地人类影响密切相关,并受到上个千年区域社会文化发展的调节。
