The aim of this thesis is to determine the level of manganese content and its seasonal dynamics in selected herbs and trees species and invertebrates in the period 2011--2013. Trial sites were located in the highly manganese contaminated ecosystem in Krušné hory mountains. The flora and fauna samples were being collected on a monthly basis. The level of manganese was determined by the AAS method. The highest level of manganese was found in the blackberry bush (Rubus caesius L.) and the raspberry bush (Rubus idaeus L.). The larch (Larix decidua Mill.) and the mountain ash (Sorbus aucuparia L.) were the most contaminated tree species. Majority of plants accumulates manganese during the vegetative period. The invertebrates showed lower level of manganese content than plants. The highest level was found in millipedes (Diplopoda) and isopods (Oniscoidea). Despite the really high concentration of manganese in the enviroment, none of the plants and invertebrates showed symptoms of toxicosis.
