The students of the International Maters Program for Environmental Engineering (IMPEE-2016) at Technical University of Hamburg, Germany ( TUHH ) got a wonderful opportunity to visit the forest and look the hydrobiology in Tostedt, near Hamburg in the excursion. The excursion started early in the morning with forecast of rain in the noon, as everyone was excited for the excursion we were ready to face the rain. Our group had total 24 students form around 15 countries over the world.
The picture was clicked by Dr. Ludwig Tent and described in more depth in his blog (Osmerus).
The first stop of the excursion includes analyzing Den Spiegel brechen.
It is clearly visible in the picture the increased structural diversity of the water plant sin the shore. The problem arising from this is the change in the depth of the water bodies which in turn led to high flow diversity.
The next stop for the excursion was in the forest, this part started with the discussion of the history of forest and problems faced by the government and land honors to keep the forest trees and habitats safe from problems. The forest which was said to be dark and full of coniferous trees is now lighter due to more and more human interference, as observed by Dr. Tent.
Himalayan Balsam or Kiss-me-on-the-mountain arise from the plant originating in the Himalayan mountains. It was found spreaded in part-dimensionally in the Este. It typically grows to 1 to 2 m high, and flowers in between June and October ( Wikipedia, 22.05.2017 ).We also were lucky to see some other plants like Chrysosplenium Alternifolium (Wechselblättrige Chrysosplenium).
From the picture the lowland forest in the background can be seen which is already developed and from right to left, the difference in the density of the trees can be easily observed.
In the picture, Fresh water shrimp (Bachflohkrebse) round and strong flow, Flat mayfly larvae of various ages are in large numbers – in smaller numbers also Stone flies – to be found in the face of the resulting small habitat diversity. (Osmerus, 23.05.2017).
For the maintenance of the water and for providing favorable environment to some stream habitats – at places where there is no effect on the drainage, some dead wood is left lying. This type of activity was observed at more than places in the forest.
We went to a very high elevation point (78.8 m above sea level – high for North German Lowland) named “Top of world” by Dr. Tent in his blog, it is a watershed between the Elbe and Weser. Before going to the top we waited in the cars as there was a very heavy thunder-storm.
In the last stop we observed Este from the above of bridge B3. The water body was prevented from the strong winds because of the bridge. the water structure and life of the water body were protected due to this. The wave view was very clear under the bridge, it was caused due to gravel sole in water which made the surface rough.
In our minibus and car we came back to the Tostedt station to catch metronome back to reach home.
Overall, it was a great excursion as everyone coming from different parts of the world got an exposure to the natural habitats here and can observe the difference in the Hydrobiology.
