Effect oh health condition on aesthetic value of green spaces in Pionirski park in Belgrade

Abstract

The relation between health condition and aesthetic value of green spaces was studied in Pionirski Park. Mean ratings of these values were compared and analyzed for different plant categories (broadleaf trees, coniferous trees broadleaf shrubs, evergreen shrubs and coniferous shrubs). It was concluded that in Pionirski Park broadleaf trees have higher aesthetic values than coniferous trees. Total aesthetic value of coniferous trees is lower than that of broadleaf trees, because the latter are infested by pests and diseases of assimilation organs, which have been present for many years in high degrees of infestation and infection. It was concluded that coniferous trees were significantly degraded thanks to inadequate maintenance, by which their aesthetic value was reduced and their life span significantly shortened. It is extremely important to research the current health condition of green spaces and to determine what reclamation measures are necessary to conserve and enhance its authenticity, cultural-landscape heritage and aesthetic value

Carulaspis juniperi (Bouche)-juniper pest (Juniperus spp.) in the Belgrade area

“…in Serbia (Kozarževskaja andVlainić, 1981, 1982;Kozarzhevskaya and Mihajlović, 1983). In recent years a significant increase in the numbers of its populations has been noted both in conifer nurseries and green areas in Belgrade (Glavendekić, 2006) and which was reflected in the very bad condition of plants (Galečić et al, 2007).…”
