On 29 September 2010 a day excursion took place in the Spreewald to the area around Lübbenau, Brandenburg. The Spreewald is one of the most popular nature experiences in Germany. The unique river landscape in Lusatia (south-east Brandenburg) with rivers whose total network is more than 1000 kilometres, is one of the most beautiful nature reserves in Europe. The extensive network of waterways, where rare animal and plant species find their habitat, was declared a biosphere reserve by UNESCO as early as 1991.
