Forest, north of the observatory and Mihajlo Pupin Institute and along the Dragoslava Srejovića street, which divides it from the neighborhoods of Karaburma and Ćalije on the north and north-east, respectively, both in the municipality of Palilula. Zvezdara Forest Zvezdara Forest (Zvezdarska šuma or Zvezdani Gaj, Serbian Cyrillic: Звездарска шума or Звездани гај) After Topčider and Košutnjak, Zvezdara is the largest forest in the urban zone of Belgrade, a crescent-shaped wooded area which covers most of the Zvezdara Hill. The northern and eastern border of the wood is formed mostly by the Dragoslava Srejovića street. It borders the neighborhoods of Karaburma on the north, Ćalije on the north-east, Mirijevo on the east, Cvetkova Pijaca on the south and Zvezdara itself on the west. In the beginning of the 20th century the Veliki Vračar Hill area was designed for afforestation. After the construction of the observatory in 1929-32 on top of the hill, the forest creation began making a unique artificially created green zone in Belgrade's urban tissue. Today, the observatory is roughly in the middle of the forest. The Zvezdara Forest today covers an area of 137 hectares, out of which 21 hectare is arranged as a park. Apart from the observatory, objects within the forest or near it include the "Mihajlo Pupin Institute" in the north-central and seven small stadiums (FC 29. Novembar, FC Zvezdara, FC Mladi proleter) in the north-western section. Patches of the northern section are urbanized, forming a neighborhood of Zvezdara II (especially along the Dragoslava Srejovića street). The forest is also damaged by the unauthorized individual residential construction, so in 2007 Belgrade City government announced further plans to extend the Zvezdara Forest to the north and south, connecting it in the process to Ada Huja and Šumice, respectively, either as real park or just avenues, and thus creating Belgrade's greenway. Number of animal species protected by Serbian and international laws live in Zvezdara forest. Some of them are: East European hedgehog (Latin Erinaceus concolor; Serbian: evropski belogrudi jež) European mole (Lat. Talpa europaea; Serbian: krtica) Common buzzard (Lat. Buteo buteo; Serbian: mišar) Tawny owl (Lat. Strix aluco; Serbian: šumska sova) Long-eared owl (Lat. Asio otus; Serbian: mala ušara) Scops owl (Lat. Otus scops; Serbian: ćuk) Little owl (Lat.
