Phitomicrobenthos of the Kłodzka Valley rivers

Ostrowska M., Ostrowski K.

Archiwum Ochrony Środowiska

2007

Vol. 33, no. 4

97-102

In the spring 2002 a qualitative and quantitative study of phitomicrobenthos organisms of the Kłodzka Valley rivers: the Nysa Kłodzka, the Biała Lądecka, and the Ścinawka was done. The species composition of algae and the number of specimen were determined on each of 9 research stands. On the basis of the species presence the saprobic area was determined in the examined part of the river. On the basis of the species number, the evaluation of self-purification capacity was carried out. The determined saprobic area allowed evaluating water cleanliness and the usefulness of the rivers as a habitat for salmon fishes.

Wiosną 2002 roku przeprowadzono badanie jakościowe i ilościowe organizmów fitomikrobentosu rzek Kotliny Kłodzkiej: Nysa Kłodzka, Biała Lądecka, Ścinawka. Oznaczono skład gatunkowy glonów oraz określono liczebność osobników na każdym z 9 stanowisk badawczych. Na podstawie obecności gatunków określono strefę saprobową na badanym odcinku rzeki. Na podstawie liczebności dokonano oceny zdolności samooczyszczania wody rzeki w badanym punkcie. Określone strefy saprobowe pozwoliły na ocenę czystości wody i przydatności rzek do bytowania ryb łososiowatych.

Twierdza Srebrna Góra, jej losy zapisane w krajobrazie

Srebrna Góra fortress, bearing the name of a historic monument, has been effectively guarded within the confines of resiliently active Cultural Park. It constitutes an exceptional relic of fortification art on the European scale, and can play a leading role in re-composition of the landscape of Bardzkie and Sowie Mountains gorge. In order to make it a proper spatial dominant, it must be exposed from among the overgrowing it greenery. The Fortress Cultural Park is an implement which makes such an activity possible. However, a question arises: in what way should the trees be cut down in order to obtain the best composition, reconciling simultaneously the historical- architectonic values of the whole complex with ecology and protection of the natural environment existing there? The spatial image of the fortress underwent considerable changes during its 230 year existence. They were closely connected with the history of the stronghold, i.e. the evolution of the first-class military object in the 18th century into a prison, an engineer polygon, a tourist object and finally a forgotten ruin in the second part of the 20th century. A model of the contemporary panorama of the fortress and town seen from the side of Brudzew was taken as a basis for the analysis. While comparing the archival photographic materials, subsequent models of similar panoramic views from different historical periods were made. Srebrna Góra fortress has a chance to be the most attractive tourist fortress in Pradziad Euroregion, without being competitive for the fortresses in Klodzko and Nysa. On the contrary, the rank of the Euroregion and its meaning in European tourism will be strengthened. The form of exposing of Srebrna Góra fortress in the landscape becomes, in this context, of great importance.
