The Tijuca Forest (''Floresta da Tijuca'' in Portuguese) is a tropical rainforest in the city of Rio de Janeiro, Brazil. It is claimed to be the world's largest urban forest, covering some 32 km² (12.4 mi²), although there are sources assigning this title to the urban forest of Johannesburg, South Africa, where between 6 and 9.5 million trees were planted. Similar to Rio de Janeiro's Tijuca Forest, the UNESCO World Heritage Site Singapore Botanic Gardens (established in 1859) is another renowned garden with a tropical rainforest within its city limits. The forest shares its name with ''bairros'' or neighborhoods of Tijuca and Barra da Tijuca that contain its entrances. It is located in a mountainous region, which encompasses the Tijuca Massif. The word ''Tijuca'' from the Tupi language means ''marsh'', and is a reference to the Tijuca Lagoon in the contemporary Barra da Tijuca. The forest forms a natural boundary that separates the West Zone of the city from the South, Central, and North ones, and the North Zone from the South one. The Tijuca Forest is a man-made reclamation of land around Rio de Janeiro that had previously been cleared and developed to grow sugar and coffee. Replanting was carried out by Major Manuel Gomes Archer in the second half of the 19th century in a successful effort to protect Rio's water supply. This followed concerns made by the Brazilian Emperor Dom Pedro II in 1861 about erosion and deforestation caused by intensive farming, as declining levels of rainfall had already begun impacting on the supply of drinking water. The Tijuca Forest is home to hundreds of species of plants and wildlife, many threatened by extinction, and found only in the Atlantic Rainforest (''Mata Atlântica'' in Portuguese). The vegetation is so dense that scientists have estimated that ambient temperatures in surrounding areas have been lowered by up to 9 °C. The forest also contains some 30 waterfalls.〔 In 1961, Tijuca Forest was declared a National Park. The Forest contains a number of attractions, most notably the colossal sculpture of Christ the Redeemer atop Corcovado mountain. Other attractions include the Cascatinha Waterfall; the Mayrink Chapel, with murals painted by Cândido Portinari; the light pagoda-style gazebo at Vista Chinesa outlook; and the giant granite picnic table called the ''Mesa do Imperador''. Among its impressive peaks is the Stone of Gávea. One favela exists in the Tijuca Forest. Its inhabitants are mainly the descendants of those who migrated to the region in the 1930s to take part in the replanting effort. Though conditions have improved recently under the Favela-Bairro Project, Mata Machado still contributes to environmental degradation in the forest.〔Duarte & Magalhaes, as cited in Del Rio & Siembieda, p. 284〕 ==Gallery== File:Floresta da Tijuca 01.jpg|Entrance File:Floresta da Tijuca 04.jpg|Sculpture at the entrance File:Floresta da Tijuca 06.jpg|Taunay Cascade File:Floresta da Tijuca 07.jpg|Restaurant File:Floresta da Tijuca 12.jpg|Job de Alcantara old Bridge File:Floresta da Tijuca 18.jpg|Mayrink Chapel File:Floresta da Tijuca 13.jpg|Stream File:Floresta da Tijuca 24.jpg|''A Floresta'' (The Forest) Restaurant File:Floresta da Tijuca 29.jpg|Fairy's Lake File:Floresta da Tijuca 30.jpg| File:Floresta da Tijuca 32.jpg|Recreation area File:Floresta da Tijuca 33.jpg|Recreation area File:Residência do Barão de Escragnolle.jpg|Former residence of the Baron of Escragnolle, now ''Os Esquilos'' (The Squirrels) Restaurant File:Floresta da Tijuca 42.jpg|The forest seen from restaurant File:Floresta da Tijuca 46.jpg|Wallace Fountain File:Açude Solidão na Floresta da Tijuca I.jpg|Solidão (loneliness) Weir File:Floresta da Tijuca 47.jpg|Solidão Weir Gate File:Floresta da Tijuca 51.jpg|Sculpture File:Floresta da Tijuca 52.jpg|Excelsior's pathway File:Floresta da Tijuca 53.jpg|Excelsior File:Floresta da Tijuca 54.jpg|Tijuca Mirim Peak seen from Excelsior File:Floresta da Tijuca 55.jpg|Plate Trail File:Floresta da Tijuca 58.jpg|Waterfall of the Souls File:Floresta da Tijuca 57.jpg|Way of the Souls File:Pedra da Gávea2.jpg|Stone of Gávea File:Vista Chinesa 01.jpg|''Vista Chinesa'' (Chinese Belvedere) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tijuca Forest」の詳細全文を読む スポンサード リンク
