Brandenburg is one of the sixteen federal-states of Germany. It lies in the east of the country and is one of the new federal states that were re-created in 1990 upon the reunification of the former West Germany and East Germany. The capital is Potsdam. Brandenburg surrounds but does not include the national capital and city-state of Berlin.
Brandenburg is known for its well-preserved natural environment and its ambitious natural protection policies which began in the 1990s. 15 large protected areas were designated following Germany's reunification. Each of them is provided with state-financed administration and a park ranger staff, who guide visitors and work to ensure nature conservation. Most protected areas have visitor centers.
