Stream ecology – comparison of two streams

In this two-day course, two mountain streams differing in drainage area (36km2 vs. 358km2) are investigated in the same manner as in the one-day course „ecology of a mountain stream“. 

The smaller of the two streams displays what is considered „good ecological status“ by EU WFD standards and does not require improvement, i.e. ‘with only a slight departure from the biological community which would be expected in conditions of minimal anthropogenic impact’. Protected as a nature reserve and fringed by a strip of riparian forest, the larger stream has not been heavily altered, so that its hydromorphological structure is dynamic and is constantly reshaped by the flow regime. Here, rare features such as braiding, meandering, islet formation, toppled trees, cut banks, gravel bars, and side channels can be seen. Despite measurable eutrophication, this structural diversity supports a biocoenosis which resembles more closely the natural state than that of the smaller stream.

Through intense involvement and by obtaining a wider basis for comparison, participants will expand their horizons and their ecological understanding.
