Due to their location close to the northern border of Romania, their complex glacial geomorphology and the existing biodiversity, the Maramureş Mountains represent an interesting area. Despite this, few palynological studies have been published so far about these mountains. Recent pollen analyses performed in Tăul Mare–Bardău and Cristina peat bogs, both located in the Northern Maramureş Mountains, reveal the Holocene regional vegetation history, beginning with the Atlantic period, as confirmed by 14C dating. High values of Corylus avellana in the bottom part of both sequences suggests an Atlantic age for the beginning of the peat accumulation. Picea abies values indicate its significant presence in the region, continuing through the entire sequence. The development of P. abies and C. avellana forest is assumed to have occurred between 9800 and 9000 cal BP, based on the general trend in the Romanian Carpathians, even though this interval is not covered by the pollen diagrams from the Maramureş Mountains. Mixed oak elements appear under-represented in the sequences because of the high altitude of the sites, similar to Carpinus betulus, whose continuous curve shows small values. The spread of mixed oak elements occurred at around 10,800 cal BP, as in most regions of the Romanian Carpathians. The Fagus sylvatica curve reaches high values during the Subatlantic period, certifying its substantial and early presence in the region. Abies alba pollen occurs continuously in the diagram only during the last period (Subatlantic), and it is poorly represented compared to beech. The beginning of C. betulus expansion is dated at ca. 6000 cal BP in Maramureş Mountains, whereas F. sylvatica starts to expand at ca. 5100 cal BP, and A. alba at only 2500–3200 cal BP. The decrease in AP/NAP ratio, observed in the last pollen zones, reflects the increasing human intervention in the region, mostly by clearing and cutting of spruce and beech forests.
