ANALYSIS OF DENDROFLORA ON THE GREEN AREAS OF SOME KINDERGARTENS IN BELGRADE (SERBIA).

Green areas of kindergartens and schools represent an important part of the system of a city's greenery and perform a range of functions like ecological, environmental, sanitary, aesthetic, educational, recreational, etc. These areas may have some woody species which are of an invasive or allergenic character. Allergenic woody species may negatively influence the children's health, or provoke certain allergic reactions. Since children spend most of their time in kindergartens, the research of the presence of allergenic species in these areas is very important. Invasive woody species could threaten biodiversity and disturb aesthetics of the green kindergarten's area by sudden and quick spreading. The research has been carried out on the green areas of four kindergartens in Belgrade. This research consists of the survey of the main elements of tree growth, the assessment of vitality and decorativeness of each tree as well as the establishment of the number of allergens and invasive species on every researched area. The obtained data have been processed in the statistical program SPSS Statistics 17.0. The results have shown the presence of 41 plant species with the total number of 359 trees on those 4 researched areas. One invasive species (Robinia pseudoacacaia L.) with the total number of 38 trees (10.6%) is present. 12 allergenic species with 133 trees have been ascertained, which is 37.0% of the total number. The species Betula pendula Roth., which pollen has very conspicuous allergenic characteristics, is present with 17 trees, and the species of the genus Tilia spp., with moderately to strongly conspicuous characteristics of pollen, with 21 tree.
