The Impact Of Human Activities In The Gutaiului Mountains, Romania, Angelica Feurdean, Ciprian Astalos
The Impact Of Human Activities In The Gutaiului Mountains, Romania, Angelica Feurdean, Ciprian Astalos
Studia UBB Geologia
The examination of pollen and charcoal from the Gutâiului Mountains in northwestern Romania and the archaeological evidence from surroundings provides some information on how past human activities have changed the vegetation in this region. The first evidence of potential human influence upon the woodlands is manifested by fire clearance recorded at approximately 7900 cal. yr BP coinciding with the Early Neolithic. The charcoal peaks at ca. 5750, 3300, 2700, 1500, 1000 cal. yr BP, and during the last 300 years are associated with episodes of decline of main woodland constituents (Ulmus, Tilia, Fraxinus, and Corylus), and the expansion of fire-precursors …

High resolution analyses of pollen, mineral magnetic properties, loss of ignition, lithostratigraphy and AMS 14C measurements of lake sediments and peat deposits accumulated in the former crater lake of Steregoiu (Gutâiului Mts., NW Romania), gave new and important information about vegetation and climate changes from the period GS-2 to the present. During the Lateglacial, three cold events were recorded: before 14,700 cal. years BP (GS-2), 14,050–13,800 cal. years BP (GI-1d), 12,900-11,500 cal. years BP (GS-1), and a warm climatic event between 13,800-12,950 cal. years BP (GI-1c to GL-1a). The Late Glacial/Holocene transition around 11,500 cal. years BP, was determined by …
Forest Conservation In A Changing World: Natural Or Cultural? Example From The Western Carpathians Forests, Romania, Angelica N. Feurdean
Forest Conservation In A Changing World: Natural Or Cultural? Example From The Western Carpathians Forests, Romania, Angelica N. Feurdean
Studia UBB Geologia
In order to plan for the future management of some of the most biodiverse forests of Europe, it is essential that we understand under which condition they arose and the time and processes responsible for their variability. Here, I highlight the main findings from the palaeoecological (pollen and charcoal), archaeological and historical investigation comprising the last 6000 years, in the Apuseni Natural Park, NW Romania and discuss the effect of the past land use and forest management on these forests. I then ask what does it mean in term of conservation values if these forests are not natural but a …

Plant Macrofossils Analysis From Steregoiu Nw Romania: Taphonomy, Representation, And Comparison With Pollen Analysis, Angelica N. Feurdean, Ole Bennike

This paper presents the results of macrofossil analysis from the Steregoiu sequence in the Gutaiului Mountains covering the last 8,000 cal BP. The studied peat deposit is characterized by abundant macrofossils. Their diversity is, however, low with most macrofossils coming from plants that grew on the mire and in the forest surrounding the basin (Carex spp., Cyperus sp., Urtica dioica, Potentilla erecta, Filipendula ulmaria, Rubus idaeus, Lycopus europaeus). The concentration of Picea abies macrofossils correlates partially well with its pollen percentages, and only when it has been present on the bog surface. The absence of macrofossils from deciduous trees, which …
