Summary Characteristics of the ecosystem of the seeping drainage waters of the Petrova Gora Memorial Park and their biological evaluation On the basis of analyses of the drainage waters of the Petrova Gora Memorial Park, the following may be concluded: The basic ecological characteristic of the drainage waters is a relatively and balanced temperature, large amounts of dissolved oxygen and low alkalinity. In addition, these are the watercourses with a small amount of water and very slow percolation in which considerable amounts of natural waste materials of plants and animals from the mentioned Park are retained. Likewise, along the settlements there increases the amonunt of waste materials of anthropogenic origin. It is characteristic of the local biocoenoses that their microphytic algae and especially Diatomeae are prevailing, which is indicative of a rather lower pollution with organic matter. Of animals, the larvae of aquatic insects are represented, and among them the Diptera. In places also the iron bacteria are developing in larger quantities. On the basis of an anlysis of biological indicators it can be attested that these waters are beta-oligosaprobic waters (2nd and 1st degrees), and beta-alfa- mesosaprobic waters (2nd and 3rd degrees). Such condition of the waters is caused by their natural pollution with organic wastes from forest plant communities. In human settlements the anthropogenic influence is more expressed. The bacteriological alalysis confirms the findings of the ecological analysis, with the understanding that the number of indicators of the potential causal organisms of intestinal infections (Coli-index) in regions where the waters flow through such settlemants increases considerably. |
