F1: Carp pond management in the area of conflict between profitability, nature conservation and climate change •    Guide(s): Christoph Köbsch, Dr. Annekatrin Wagner, Dr. Alexandra Segelken-Voigt (Fisheries officer, Landesamt für Umwelt, Landwirtschaft und Geologie in Königswartha)•    Capacity: 17 people•    Cost: Bus transfer•    Start: 8:30 o’clock•    End: 16:30 o’clock•    Meeting point: University or Hauptbahnhof (still to be clarified)•    Destinations: Königswartha and Pond area in the Upper Lusatian Heath and Pond Landscape Biosphere Reserve For over 750 years, ponds have been utilized for carp production in Saxony. Over time, this has created a unique cultural landscape. The approximately 9,000 hectares of ponds in Saxony that are currently still farmed provide a habitat for numerous rare animal and plant species, so that most of the pond areas are now subject to natural protection (FFH, nature reserve or similar). Nature conservation-related restrictions on management practices, climatic changes and water scarcity as well as predator effectx are leading to a decline in profitability for local fishing businesses. However, as a cultural landscape, the preservation of these habitats is inevitably linked to active management and maintenance of the ponds. As part of the excursion, pond areas in Saxonian Lusatia will be visited, where the above-mentioned tensions will be discussed with experts on site. More info: https://www.biosphaerenreservat-oberlausitz.de F2: Lusitian mining lakes (Senftenberg and Surroundings) •    Guide(s): Dr. David Kneis und Steffen Kunze•    Capacity: 18 people•    Cost: Bus transfer•    Start: 8:30 o’clock•    Ende 17 o’clock•    Meeting point: University (Institute of Hydrobiology, Drude-building)•    Destinations: Welzow, Geierswalde, Niemtsch The excursion shows the dimensions of open-cast lignite mining in Lusatia and provides an insight into the complex problems of recultivation. We will visit prominent vantage points in the Senftenberg mining district, learn about artificial lakes in various stages of formation and discuss specific management issues. The trip is organized by minibus (approx. 3 hours travel time in total). Shorter hikes are on easy terrain. F3: Reservoirs in the Ore Mountains and the Klingenberg waterworks •    Guide(s): Johannes Feldbauer, together with experts from the Saxonian Reservoir administration and the waterworks•    Capacity: 18 people•    Cost: Bus transfer, tour through the waterworks•    Start: 09:00 o’clock•    Ende: 16:00 o’clock•    Meeting point: University or Hauptbahnhof (still to be clarified)•    Destinations: Klingenberg, Dippoldiswalde, Frauenstein Historic and at the same time modern renovated dam (drinking water, water quality management, flood protection) and waterworksThe excursion goes to the Klingenberg/Lehnmühle interconnected reservoir system, which is used for the drinking water supply of Dresden and Freital as well as parts of the district of Saxon Switzerland-Eastern Ore Mountains. The Klingenberg dam was built between 1908 and 1914 and was extensively renovated between 2005 and 2013 and therefore has a modern extraction tower which allows raw water to be extracted from six different horizons. We are guided through the dam wall and also want to take a look at the pre-dam. We will be accompanied on site by employees of the Saxonian reservoir administration, who will tell us about the operation and limnology of the dam from various aspects such as drinking water production, water quality management and flood protection. Directly connected to the dam is the Klingenberg waterworks, which we will also visit. More info:https://www.wasserwirtschaft.sachsen.de/TS_Klingenberg.htmlhttps://www.wvwgmbh.de/meine-wvwgmbh/klingenberg F4: Nationalpark Sächsische Schweiz, Polenztal, Gamrigfelsen •    Guide(s): Dr. Thomas Petzoldt and Jens Posthoff (National park administration)•    Capacity: 25 people•    Cost: Public transport tickets for S-Bahn and Bus, ticket for yaw ferry Rathen•    Start:08:30 o’clock•    End: 16:30 o’clock•    Meeting point: Hauptbahnhof, S-Bahn • Route: Hockstein-Polenztal-Gamrig-Kleine Bastei-Rathen•    Notes: The excursion has the character of a low mountain hike (approx. 10 km). Please wear sturdy shoes and clothing suitable for the weather and bring sufficient food and drink to meet your personal needs. The aim of the excursion is to give an insight into the work of the National Park and Forest Administration in general and in this case into the development of nature and streams. The Polenz River will be used as an example to illustrate the characteristics of a typical wild stream, its shaping power and interaction with geological processes. We will learn about the natural development of the forest, the path to it, and land management in the area of conflict between the experience of a largely untouched landscape, the security needs of people, and the purpose of nature conservation in a national park. At the same time, the high variability of habitats in a small area provides favorable conditions for site-adapted specialists, which we will learn about. See also: https://www.nationalpark-saechsische-schweiz.de F5: Central wastewater treatment in Dresden-Kaditz under the aspect of water reuse and energy utilization in urban areas •    Guide(s): Sara Schubert, Dr. Uli Klümper and Dr.-Ing. Matthias Barth (Stadtentwässerung Dresden)•    Capacity: 15 people, half day excursion, tour lasts 2-3hours•    Cost: Public transport ticket•    Start: 09:00 o’clock•    End: 12:00 o’clock•    Meeting point: Wastewater treatment plant Dresden Kaditz•    Notes: Arrival via public transport, sturdy shoes, weather-appropriate clothing, sun protection, no visiting costs The central wastewater treatment plant in Dresden-Kaditz treats wastewater from Dresden and the surrounding municipalities (690,000 population equivalents). A particular challenge is the increasing population in the region and the growing semiconductor industry north of the city. In addition, the new EU wastewater directive and increased water protection measures (e.g. against combined sewer overflows during heavy rainfall events) must be taken into account in the city of Dresden’s wastewater disposal concept. A tour shows the various stations of the current and planned wastewater treatment as well as special historical buildings. You can find out more in the media library of Stadtentwässerung Dresden.
