According to radiometric dating of palynology [1,2], in the Holocene, Scotch pine population expanded rapidly from Alpine mountains to Baltic and English Channel (La Manche) regions (300-600 km/1000 years). Such a rapid dispersal could not be only anemochorous, which rate, according to our observations [3, 4], does not usually exceed 50-60 km/1000 years for pine (Pinus sylvestris L.) and spruce (Picea abies Karst.). We also observed that the seeds of these trees are capable of floating and long-distance dispersal over river water. This permitted us to put forward a hypothesis about the important role of seed hydrochory in their dispersal [4].
