BIOGEOGRAPHICAL PROVINCE 8.04.01 (Guyanan)
GEOGRAPHICAL LOCATION Canaima national park is
located in the south-east of Venezuela in Bolívar State (Piar and
Roscio districts). The park protects the Venezuelan (north-western) section
of the Guayana Shield. It is bordered by the Río Carrao and the
Lema Mountain Range to the north, the Pakaraima Range as far as the Brazilian
border to the south, the headwaters of the Río Venamo and the Roraima
Range as far as Roraima-tepui to the east, and the Río Caroní
to the west. The nearest city is Ciudad Bolívar some 600km to the
north. 4° 41'-6° 29'N, 60° 40'-62° 59'W
DATE AND HISTORY OF ESTABLISHMENT Canaima was
established as a national park on 12 June 1962 by Executive Decree No.
770, and management is regulated under the Forest Law of Lands and
Waters, 1966. Its size was doubled to the present area under Executive
Decree No. 1.137 of 1 October 1975. National park objectives are stated
in the 1983 Organic Law of Territorial Planning as natural areas
unaffected by human disturbance where recreation, educational activities
and research are encouraged. Inscribed on the World Heritage List in 1994.
AREA 3,000,000ha
LAND TENURE Government. The traditional occupants,
the Pemón, have claimed land rights (Government of Venezuela, 1993).
ALTITUDE 450m to 2,810m
PHYSICAL FEATURES Canaima includes the uplands
of the Gran Sabana and the eastern table mountains (tepuis) of
the Roraima Range, as well as the sandstone plateau of Chimantá
and Auyán-tepui and the north-western Canaima lowlands. It comprises
Precambrian rocks which have been subjected to 600 million years of erosion
to form a spectacular landscape. It is composed mainly of horizontal sandstone
and lutite strata with inserts of igneous rocks (diorite dykes and colse).
There are three disjunct physiographic units: undulating lowlands between
350 and 650m; the flat plateau of the Gran Sabana (800-1500m); and the
tepui summits (2000-2700m). The summits reach 1000-2000m above the surrounding
plateau and their surfaces are often scarred by gullies, canyons and sinkholes
of several hundred metres depth. Water drains from the flat summits forming
hundreds of waterfalls. The Río Caroní, with its many tributaries
arising within the park, supplies the Guri dam which provides electricity
to large areas of the country. There are many waterfalls in the park including
Angel Falls, the world's tallest at 1002m (Government of Venezuela, 1993).
CLIMATE The climate of the great savanna plateau
is temperate with a mean annual temperature of 24.5° C with the temperatures
on tepui summits as low as 0° C during the night. Precipitation varies
greatly depending on local orographic features though mean annual rainfall
is 2600mm. In the north-west of the park, there is a dry season between
December and April, whereas in other areas rainfall is more or less constant
throughout the year (Government of Venezuela, 1993).
VEGETATION The most important types of vegetation
are: savanna, moriche Mauritia groves, shrublands, montane forests
and pioneer vegetation on the summits of the tepuis. Savannas can be divided
into two types. On poor sandy soils, extensive grass savannas dominated
by Trachypogon plumosus (IK) and Axonopus pruinosus (IK)
are found. On more localised damp, richer soils, herb savannas consisting
of Stegolepis ptaritepuiensis (IK), S. guianensis (IK) and
Brocchinia steyermarkii occur. Forests are only found along rivers,
in damp depressions and on the lower slopes and gullies of the tepuis.
Tepui vegetation is characterized by endemic species and carnivorous plants,
for example Heliamphora spp., Drosera roraima (IK) and Utricularia
humboldtii (IK). The Canaima national park contains an estimated 3000-5000
species of phanerogams and ferns. The tepui system (comprising all the
tepui formations and known as Pantepui) contains a high proportion
of endemic taxa. For example, 900 species of higher plants have been identified
from Auyán-tepui, of which some 10% are endemic to this massif.
Canaima is also famous for its diversity of orchids, with an estimated
500 species recorded in the park (Government of Venezuela, 1993).
FAUNA The fauna is diverse, though not very abundant:
118 mammals, 550 birds, 72 reptiles and 55 amphibians have been recorded
(Government of Venezuela, 1993). There are six species of mammals of conservation
concern: giant anteater Myrmecophaga
tridactyla (V), giant armadillo Priodontes
maximus (V), giant otter Pteronura
brasiliensis (V), bush dog Speothos
venaticus (V), little spotted cat Leopardus
tigrinus (K) and margay Leopardus
wiedii (K) (Groombridge, 1993). The only endemic mammal is the
rodent Podoxymys
roraimae. The avifauna is varied and contains over thirty species
endemic to Pantepui (ICBP, 1992). The less mobile orders, amphibians,
reptiles and fish, exhibit even higher levels of endemism.
CULTURAL HERITAGE The forests and savannas have
been occupied for 10,000 years by various groups of Amerindians of the
Carib family, collectively known as the Pemón. Indeed, the savanna
formations of the Gran Sabana itself are almost certainly a product of
regular burning by indigenous inhabitants in prehistoric times. Two archaeological
sites, containing various hand-fashioned stone tools estimated to be 9000
years old, have been found in the park (Government of Venezuela, 1993).
LOCAL HUMAN POPULATION The park is sparsely inhabited,
mostly by Pemón, with less than one person per kmē and a total
population of 10,000. The Pemón live mainly in the eastern sector
of the park in scattered communities of 40-100 individuals. Many Pemón
maintain traditional lifestyles of swidden agriculture, hunting and gathering.
They also trade artifacts. They now have access to drinking water, electricity,
schools and basic medical care (Government of Venezuela, 1993).
VISITORS AND VISITOR FACILITIES Tourism is encouraged
but restricted to designated areas such as Laguna de Canaima in the western
sector of the park which can only be reached by air and where a limited
number of concessionaries provide visitors with board, lodging and recreational
services. A main road from Ciudad Bolívar runs along the eastern
border of the park through the Gran Sabana, bisecting its south-east corner.
There are no other metalled roads within the park, the western section
being accessible only by air.The park currently receives 100,000 visitors
per year, 90% of whom visit the Gran Sabana (Government of Venezuela,
1993).
SCIENTIFIC RESEARCH AND FACILITIES The first scientific
research was carried out by the naturalist Sir Robert Schomburgk in 1838.
The first tepui summit was reached in 1884, and research on these areas
has continued ever since (Government of Venezuela, 1993).
CONSERVATION VALUE Canaima National Park exhibits
an exceptional geomorphology produced by weathering processes. The distinctive
tepui formations give rise to numerous waterfalls, including Angel Falls,
the world's highest. The high level of endemism found on the summits of
the tepuis has led to the recognition of Pantepui as a unique biogeographical
entity. Canaima is the homeland of one of the largest Amerindian populations
in the country. The park protects the headwaters of the Río Caroní
which supplies Guri, the country's largest hydroelectric power station
and source of 60% of the nation's energy (Government of Venezuela, 1993).
CONSERVATION MANAGEMENT Santa Elena de Uairén,
a town lying 20km to the south of the park, is the main administrative
centre. The park is divided into two sectors for administrative purposes.
A management plan and regulations for the eastern section of the park
were issued under Decree No. 1,640 dated June 5 1991. Objectives formulated
in the management plan include provisions for indigenous agricultural
production under strict regulation. Other activities are strictly controlled
and hunting and collection of wildlife is forbidden. There is no management
plan for the western sector of the park (Government of Venezuela, 1993).
The park is currently under the administration of INPARQUES, the National
Institute of Parks (IUCN, 1997).
MANAGEMENT CONSTRAINTS According to the Government
of Venezuela (1993), most of the threats to the park result from poor
on-site management which is a product of insufficient financial and human
resources. The conservation of the park is in jeopardy due to lack of
qualified personnel and appropriate visitor facilities and the inability
of the management to control activities within the park. The main problems
are: illegal gold mining activities causing siltation and mercury contamination
of watercourses; excessive burning of vegetation by indigenous people;
and soil erosion, soil compaction and litter resulting from tourism (Government
of Venezuela, 1993). Mass tourism is rapidly growing, with road construction,
illegal airstrips, and helicopter flights opening up previously inaccessible
areas. there is also a tangible risk of fire accidently spreading from
campsites (WWF and IUCN, 1997). The park is also under threat from a project
supported by the Government of Venezuela to construct a series of power
transmission lines running 160km from the Guri Dam to the north of the
park to Brazil and to a mining site north of the park. Local people were
not consulted about the scheme, and no adequate Environmental Impact Assessment
was carried out. The development may encourage mining and logging in the
park, and will damage the cloud forests on the low table mountain of Sierra
de Lema in the north of the park, one of the areas richest in endemism
in Venezuala (Sharpe and Rodriguez, 1997, IUCN, 1997). Large-scale mining
operations have started up outside the park over the over the past few
years causing deforestation and contamination of local rivers (IUCN, 1997).
STAFF Until recently there were no staff monitoring
the park, although there is now a team of 10 park guards and 3 technicians
(Sharpe, 1996).
BUDGET The budget was Bs. 150,466 (US$37,000)
for the 1982 financial year (IUCN, 1982). More recent information is not
available.
