66. Lake Vapsko-2, Rila Mountains (Bulgaria).

The coniferous belt became dominated by I Pinus peuce i , I Picea abies i , I Pinus sylvestris i and some I Abies alba. i The human impact was not very intensive, most probably due to the partial abandonment of the high-mountain pasture in recent times. At lower altitudes were distributed I Pinus peuce i , I Abies alba i , some I Betula i and stands of I Alnus i in wetter places and along mountain brooks I . i The presence of deciduous tree pollen ( I Quercus i , I Tilia, Carpinus i , I Corylus i ) can be explained by aerial upslope transport from the mixed oak forests. Four local pollen assemblage zones (LPAZs), which correspond to successive stages of vegetation history (LV-1 to LV-4), can be recognized: I LPAZ LV-1, 490-425 cm (~6200-5940 cal. bp) i The lowermost section of the pollen record, as confirmed also by the find of subfossil stomata, reveals that stands of I Pinus i (most likely I Pinus mugo i ) and I Juniperus i occupied the slopes in the surroundings of the lake.
