Abstract

The paper presents the floristic diversity of the left bank of the Danube and the canal network of Krnjaca and Borca settlements, as well as the factors that endanger it. 216 autochthonous and allochthonous plant species were recorded in the investigated area. A large number of invasive plant species have been observed that spread rapidly and easily forming stable populations that displace native plants. Some of them are: Amorpha fruticosa L., Robinia pseudoacacia L., Ailanthus altissima (Mill.) Swingle, Asclepias syriaca L., Ambrosia artemisiifolia L. and others. The presence of 6 species that are rare and endangered in Serbia is especially significant, as well as 5 relict species. During the investigation, the factors which influence on natural habitats degradation and the reduction of autochthonous floristic diversity were identified. Accordingly, measures for protection and preservation of autochthonous floristic diversity are recommended.

Summary

Introduction

Floristic diversity and plant distribution are one of the indicators of ecological conditions of a certain ecosystem (Ko j i ć et al, 1994). The preservation and conservation of the autochthonous flora of each area is very important. Even if the habitats do not change completely, but only if they become fragmented, significant disturbances occur within the ecosystem (S te va nović , Va s i ć , 1995). Another factor which influences on the loss of floristic diversity, especially in urban and suburban areas, is the introduction of invasive species. In order to preserve the biodiversity of any area, especially anthropogenic habitats, it is of special importance to prescribe and implement certain protection measures. Floristic diversity, can be preventive and repressive
