One of the defining features of the park is the presence of tepuis
(the Native American word for table-top mountains), sheer-sided sandstone plateaux that dominate the forest.
The most significant of these is Canaima National Park--a 12,000-square-mile unesco World Heritage site known for its unique topography of flat-topped mountain formations known as tepuis
. One third of the plants here are found nowhere else on the planet.
The area is divisible into: 1) "highlands" along the Western border of the Amazonas State and upper courses of the Ventuari and Orinoco Rivers (mountain landscapes covered by evergreen forests and scattered with tabletop mountains, tepuis
), and 2) "lowlands", peneplains and low hills along the Casiquiare Canal and the Guainia-Rio Negro, Ventuari and Orinoco Rivers (covered by evergreen forests, grassland and scrubland) (Schargel, 2011).
Plants can be predators too: carnivorous plants dominate in nitrogenpoor habitats such as acid bogs in the Boreal Forest or high on the tablelike "Tepuis
" of Venezuela in South America.
This new two-part documentary sees him undertaking his riskiest assignment yet, as he explores Venezuela's tepuis
, the ancient, sheer-sided mountains of Canaima National Park.
"They are utterly spectacular," says Steve of the Tepuis
BACKSHALL'S EXTREME ADVENTURE BBC2, "They are utterly spectacular," says Backshall of the Tepuis
. "Some of them just jut out of the rainforest - hundreds of metres of vertical sandstone - they are jaw-dropping, and yeah, I managed to convince the BBC that they should send us out there for a month exploring, and we got rather more than we bargained for...
The naturalist has embarked on one of the most dramatic and dangerous expeditions filmed by a BBC crew, to explore Venezuela's tepuis
- the ancient, sheer-sided, table-top mountains of Canaima National Park.
'I went looking for adventure and got more than I bargained for,' says the naturalist, who was there to explore tepuis
- huge flat-topped mountains in Canaima National Park.
This markedly seasonal climate separates the CRs from other Neotropical open outcrop and montane formations which lack an arid season, such as the aforementioned campos de altitude and the Tepuis
of the Amazon region.
