Flora and fauna

Green space covers almost a quarter of Warsaw's total area. These range from small neighborhood parks and green spaces along streets or in courtyards, to tree-lined avenues, large historic parks, nature conservation areas and urban forests at the fringe of the city. There are as many as 82 parks in the city; the oldest ones were once part of representative palaces and include the Saxon and Krasiński Gardens, Łazienki Park (Royal Baths Park) and Wilanów Palace Parkland.

The Saxon Garden, covering an area of 15.5 ha, formally served as a royal garden to the now nonexistent Saxon Palace. In 1727, it was made into one of the world's first public parks and later remodelled in the forest-like English style. The Tomb of the Unknown Soldier is situated at the east end of the park near the central fountain, on Piłsudski Square. With its benches, flower carpets and a central pond, the Krasiński Palace Garden was once a notable strolling destination for most Varsovians. The Łazienki Park covers an area of 76 ha and its unique character and history is reflected in the landscape architecture (pavilions, sculptures, bridges, water cascades) and vegetation (domestic and foreign species of trees and shrubs). The presence of peacocks, pheasants and squirrels at Łazienki attracts tourists and locals. The Wilanów Palace Parkland on the outskirts of Warsaw traces it history to the second half of the 17th century and covers an area of 43 ha. Its French-styled alleys corresponds to the ancient, Baroque forms of the palace.

The Botanical Garden and the University Library rooftop garden host an extensive collection of rare domestic and foreign plants, while a palm house in the New Orangery displays plants of subtropics from all over the world. Mokotów Field (once a racetrack), Ujazdów Park and Skaryszewski Park are also located within the city borders. The oldest park in the Praga borough was established between 1865 and 1871.

The flora of Warsaw may be considered very rich in species on city standards. This is mainly due to the location of Warsaw within the border region of several big floral regions comprising substantial proportions of close-to-wilderness areas (natural forests, wetlands along the Vistula) as well as arable land, meadows and forests. The nearby Kampinos Nature Reserve is the last remaining part of the Masovian Primeval Forest and is protected by law. The Kabaty Woods are by the southern city border and are visited by the residents of southern boroughs such as Ursynów. There are 13 natural reserves in the vicinity and just 15 kilometres (9 miles) from Warsaw, the environment features a perfectly preserved ecosystem with a habitat of animals like the otter, beavers and hundreds of bird species. There are also several lakes in Warsaw – mainly the oxbow lakes at Czerniaków and Kamionek.

The Warsaw Zoo covers an area of 40 hectares (99 acres). There are about 5,000 animals representing nearly 500 species. Although officially created in 1928, it traces back its roots to 17th century private menageries, often open to the public.
