Abstract

Pollen analysis as a technique for reconstructing former vegetation by means of fossil pollen grains preserved in the sediments was ´born´ in 1916, when Swedish geologist Lennart von Post (1884-1951) presented the first percentage pollen diagram at the meeting of the Swedish Geological Society, held in Kristiana (now Oslo). A combination of the following unique features makes pollen analysis such a useful tool for palaeoenvironmental studies: (a) plants produce pollen in great quantities; (b) pollen grains are easily dispersed by wind, water or insects and occur in almost all types of sediments on all continents except Antarctica; (c) the outer coat of pollen grain build of the biopolymer "sporopollenin" is extremely resistant to mechanical and chemical agents and well preserved even in very old sediments; (d) a great quantity of pollen grains representing past vegetation which grew around the sampling site can be easily recovered from fossil sediments; (e) most of the pollen grains recovered from Quaternary deposits can be identified to the species, family level and the resulting pollen assemblage allows statistical treatment. - (IfL)
