Belgrade has the reputation of one of the greenest capitals in Europe, because it has large oases of nature both in the center and on the outskirts of the city. In the forests at the periphery of Belgrade live dozens of species of rare birds. As the sights of nature, 182 individual trees have been listed and protected in Belgrade. The green assets of Belgrade cover an area of over 4 000 hectares. 

Compared to the build area, Belgrade parks are small and unequally allocated among the municipalities. In the parks dominate high trees, mainly deciduous species. There is around 30 different deciduous trees: maple and chestnut, linden, sycamore, acacia, poplar, ash, birch, etc. From conifer trees there are mainly: pine, fir, larch, cypress, etc. The Belgrade parks are considered as young – around 80-90 of trees are younger than 60 years. 

The oldest park is Topčider, formed in the valley of Topčider river. In the first half of 19th century this landscape was full of vineyards and weekend houses of wealthy people. In 1831 Knez Miloš Obrenović started arranging the park, along with building the house, church, restaurant and casern.
