The sediments of profiles ZH P-2, 5, 7, 8b, 9, 10 and 11 from Za Hájovnou Cave (Javoříčko Karst) were studied from a palynological point of view. Most of layers (except layer 1c/ZH P-10, layer 7e /ZH P-2) were paleontologically dated as Holsteinian Interglacial. The alynospectra confirmed the mild character of the climate during sediment deposition (Carpinus, Hedera, Acer, Tilia, Corylus, single Pterocarya and Ilex). The proportion of individual elements as well as relationship between trees and herbs varied. Changes in number of morphologically different pollen grains (primarily Pinaceae, Asteroideae) in correlated layers (2a, 2b/ ZH P-5 and 2,2b/ZH P-8b, and layer 4 – debris cone) from profiles ZH P-10, ZH P-11and ZH P-8b were recorded in the direction towards the cave interior. This phenomenon is most likely related to the resistance of the pollen grains to chemical and mechanical conditions during transport.
