从泥炭芯的花粉分析7.0米长，取自Bisoca附近的沼泽，在中海拔地区的Buzalitului亚喀尔巴阡山脉，是用来重建该地区的冰后期植被历史。植被记录，这是由12个14 C日期支持，开始在晚冰期结束。在晚冰期/全新世过渡期，开放的植被被森林所取代，这表明对气候变暖的快速反应。全新世开始与扩张的桦木，松和榆树，其次，11,000卡年BP后，由白蜡树，栎，椴树和云杉。这些类群的迅速扩张可能是由于它们在晚冰期期间在该地区的存在。在约9200 cal yr BP，Corylus扩张，在7600 cal yr BP后达到最大值。Carpinus的建立发生在ca。7200 cal yr BP，最大值约为1.5 cal yr。5700 cal yr BP.水青冈花粉定期记录后7800卡年BP，并成为占主导地位的约。2000 cal yr BP。人类活动的第一个迹象出现在3800 cal yr BP左右。
Pollen analysis from a peat core 7.0 m in length, taken from a bog near Bisoca, in a mid-altitude area of the Buzăului Subcarpathian mountains, is used to reconstruct the postglacial vegetation history of the region. The vegetation record, which is supported by twelve 14C dates, starts at the end of the Late Glacial period. At the Late Glacial/Holocene transition, open vegetation was replaced by forest, suggesting a fast response to climatic warming. The Holocene began with the expansion of Betula, Pinus and Ulmus, followed, after 11,000 cal yr BP, by Fraxinus, Quercus, Tilia and Picea. The rapid expansion of these taxa may be due to their existence in the area during the Late Glacial period. At ca. 9200 cal yr BP, Corylus expanded, reaching a maximum after 7600 cal yr BP. The establishment of Carpinus occurred at ca. 7200 cal yr BP, with a maximum at ca. 5700 cal yr BP. Fagus pollen is regularly recorded after 7800 cal yr BP and became dominant at ca. 2000 cal yr BP. The first indications of human activities appear around 3800 cal yr BP.
