We apply several pollen preparation methods as the preparation technique must be related to the different matrices in which the pollen may be embedded. Pollen and spores counts are based on fixed pollen sum. For absolute counting we therefore use the exotic marker grain method.
Our equipment for counting pollen, spores and plotting pollen diagrams consists of:
Zeiss Akloskop, Zeiss Axioscop 50 equipped with a Leica DFC 420 digital camera, Easy count (an electronic counting sheet), Research Assistant 5 professional (pollen database) and Tilia and Tilia.graph (plotting program).
