The Tijuca
National Park is an
Integral Protection
Conservation Unit
of the
Mata Atlântica
Biosphere Reserve
in the state of
Rio de Janeiro.
Together with
Serra da Cantareira
in
São Paulo it is considered the largest
urban forest in the world
(see
map).
Due to intensive deforestation, erosion and rainfall reduction because of to the creation of sugar cane- and coffee
plantations during the 19th century, Rio de Janeiro's drinking water supply was reduced to such extent, that
King Don Pedro II in 1861 decided to reforest the affected areas.
Within 10 years, Tijuca was reforested by engineer M. G. Archer by planting more than 40.000 native species.
