CHANGES IN MACROPHYTE COMMUNITIES OF SUBURBAN LAKE TRACKIE SUBJECT TO ANTHROPOPRESSURE

Keywords: anthropopressure, macrophytes, anthropopressure indices, dysharmonious lake
Abstract: Studies of water, mud and rush vegetation in Lake Trackie, carried out in 2001 to determine the influence of anthropogenic factors, showed that the phytolittoral area decreased in comparison with 1991 [Ciecierska 1994]. One hundred and fourteen plant species were recorded; none of them was a protected species or one of special natural value. Sixteen plant communities were identified, five of which created a protection zone of the lake. As compared to the state of 1991 [Ciecierska 1994], there was an increase in the area covered by mud and rush communities and a reduction in the area of water phytocenoses. The ratio of the area occupied by water plants to that with rush vegetation indicates that the latter plays now a more important role in the lake. The rise in the values of the synanthropisation index (Ws) and the synanthropic quotient (Ilsyn) points to the increased impact of endogenic factors of anthropogenic origin on the phytolittoral of the lake, resulting in its dysharmonious development. The values of the phytocenotic diversity index (H) remained stable during ten years, which suggests that the lake is able to recover if the inflow of allogenic nutrients is cut off.
