Parks are the green lungs of a city. In parks and on rural estates, the planting sites of trees come as close as possible to their natural conditions and they get the space to grow. Thus, parks are where ecosystem services are most clearly reflected.
The design of the parks over the centuries is a reflection of society. In the Middle Ages the hunting forests were private domains, in the 17th and 18th centuries they were used to show off wealth, and from the middle of the 18th century the English landscape parks indeed became a window to show how worldly a person was. Subsequently, philanthropists brought the English landscape park to the city, and so the first parks where the public could walk or go boating were created. However, it took until the 1930s, with the development of the public parks in Germany, before the park took on more functions.
