The Siebengebirge area once served as a trachyte quarry. It was purchased by the Prussian state in 1836 and set aside as the first state sponsored reserve. Germany has designated almost 50% of its territory as limited or fully protected environmental reserves, one of the highest percentages in the world.

Aquila chrysaetos - The golden eagle is the most widely distributed of eagles. It has a range covering Eurasia, North America, and parts of Northern Africa. Male and female pair for life and maintain territories as large as 200 square kilometers. A breeding pair will build several nests, also known as eyries, throughout their territory and use them on an alternating basis. Two eggs are normally produced during each breeding cycle. The eggs are hatched after about 45 days of incubation. It is usually the male’s duty to provide the hatchlings with food.
