The Nariva Formation is a geologic formation in Trinidad and Tobago. It preserves fossils dating back to the Paleogene period. [1]
Trinidad and Tobago is an archipelagic republic in the southern Caribbean between the Caribbean Sea and the North Atlantic Ocean, northeast of Venezuela. They are southeasterly islands of the Lesser Antilles, Monos, Huevos, Gaspar Grande, Little Tobago, and St. Giles Island. Trinidad is 11 km (6.8 mi) off the northeast coast of Venezuela and 130 km (81 mi) south of the Grenadines. The island measures 4,768 km2 (1,841 sq mi) in area with an average length of 80 km (50 mi) and an average width of 59 km (37 mi). The island appears rectangular in shape with three projecting peninsular corners. Tobago is 30 km (19 mi) northeast of Trinidad and measures about 298 km2 (115 sq mi) in area, or 5.8% of the country's area, 41 km (25.5 mi) in length and 12 km (7.5 mi) at its greatest width. The island is cigar-shaped in appearance, with a northeast–southwest alignment.
Trinidad is the larger and more populous of the two major islands of Trinidad and Tobago. The island lies 11 km (6.8 mi) off the northeastern coast of Venezuela and sits on the continental shelf of South America. It is often referred to as the southernmost island in the West Indies. With an area of 4,768 km2 (1,841 sq mi), it is also the fifth largest in the West Indies.
The Northern Range is the range of tall hills across north Trinidad, the major island in the Republic of Trinidad and Tobago. The hills range from the Chaguaramas peninsula on the west coast to Toco in the east. The Northern Range covers approximately twenty-five percent of the land area of Trinidad.
Mayaro is the name of a county on southeastern Trinidad island, in Trinidad and Tobago.
Caroni County was a historic county of Trinidad and Tobago. It occupies 557 km2 (215 sq mi) in the west central part of the island of Trinidad, the larger island in the Republic of Trinidad and Tobago. It lies south and southwest of Saint George County, west of Nariva County and north of Victoria County. To the west it is bounded by the Gulf of Paria. County Caroni includes the towns of Chaguanas, the largest town in the country and Couva, the capital of the Couva–Tabaquite–Talparo region. Administratively it is divided between the Borough of Chaguanas, the Region of Couva–Tabaquite–Talparo and the Region of Tunapuna–Piarco. The county was divided into four Wards: Chaguanas, Couva, Cunupia and Montserrat. The major towns of County Caroni are Chaguanas and Couva. The port and industrial zone of Point Lisas is located in Caroni, and the region is also a site for agriculture.
The blue-and-yellow macaw, also known as the blue-and-gold macaw, is a large South American parrot with mostly blue top parts and light orange underparts, with gradient hues of green on top of its head. It is a member of the large group of neotropical parrots known as macaws. It inhabits forest, woodland and savannah of tropical South America. They are popular in aviculture because of their striking color, ability to talk, ready availability in the marketplace, and close bonding to humans. They can also live for 65–70 years.
The Nariva Swamp is the largest freshwater wetland in Trinidad and Tobago and has been designated a Wetland of International Importance under the Ramsar Convention. The swamp is located on the east coast of Trinidad, immediately inland from the Manzanilla Bay through Biche and covers over 60 square kilometres (23 mi2). The Nariva Swamp is extremely biodiverse. It is home to 45 mammal species, 39 reptile species, 33 fish species, 204 bird species, 19 frog species, 213 insect species and 15 mollusc species. All this contained in just 60 square kilometers.
The Legislative Council of Trinidad and Tobago served as an advisory commission to the governor in British-ruled Trinidad and Tobago, between 1831 and independence in 1962. The Legislative Council consisted of a mixture of appointed and elected members. After the introduction of elected representation in 1925 the council consisted of 13 "unofficial" members, seven elected and six appointed. Over time the balance between elected members and appointed members changed. In 1956, the council consisted of 24 elected and 7 appointed unofficial members.
Nariva is a county in Trinidad and Tobago. It is located in eastern Trinidad, south of Saint Andrew County and north of Mayaro County, to the west by Victoria County and to the northwest by Saint George County. The southern boundary of the county lies along the Ortoire River and the western boundary is Cocos Bay. The towns of Rio Claro and Ecclesville are located in Nariva County. The Nariva Swamp is located in the eastern part of Nariva County.
Victoria was a county on Trinidad island in Trinidad and Tobago.
The counties of Trinidad and Tobago are historic administrative divisions of Trinidad and Tobago. Trinidad was divided into eight counties, and these counties were subdivided into wards. Tobago was administered as a ward of Saint David County.
Saint Andrew is a county in Trinidad and Tobago which occupies 740 km2 (290 sq mi). It is located in northeastern Trinidad, east of Saint George County, south of Saint David County and north of Nariva County. To the east it is bounded by the Atlantic Ocean. The major town in the county is Sangre Grande. Saint Andrew is divided into five Wards - Valencia, Matura, Manzanilla, Tamana and Turure.
Founded in 1966, the Pointe-à-Pierre Wild Fowl Trust is a not for profit environmental non-government organisation dedicated to environmental education and the conservation of wetlands and waterfowl. Located in Pointe-à-Pierre, Trinidad and Tobago, the trust contains two lakes and about 25 hectares within the Petrotrin oil refinery.
The Trinidad Regional Virus Laboratory (T.R.V.L.) was established in Port of Spain, in 1953 by the Rockefeller Foundation in co-operation with the Government of Trinidad and Tobago. It was originally housed in an old wooden army barracks near the docks in Port of Spain. A large wired-in "animal house" was built out back to house the many wild animals brought in for study.
The Ortoire River is a river in Trinidad and Tobago. It forms the boundary between Nariva County and Mayaro County in east Trinidad.
The Nariva River is one of the larger rivers in Trinidad and Tobago. It drains the Nariva Swamp on the east coast of Trinidad. The river is a dark cream in colour. The bridge used to be a box type iron but it has been replaced with concrete and it also has been raised to prevent flooding. It is also good for kayaking. West Indian Manatees have been known to use this water course.
On the island of Trinidad in the Republic of Trinidad and Tobago, the Caroni Plain is a lowland area between the Northern Range and the Central Range. The lowland areas to the south of the Central Range are the Naparima Plain on the west and the Nariva Plain on the east. The lowland areas are either flat or consist of gently rolling hills. The 25-mile long Caroni river flows westward through the Caroni Plain and drains into the Caroni Swamp on the Gulf of Paria coast. The Caroni Plain was a major region of sugar and cocoa production in the 18th and 19th centuries and the first half of the 20th century.
On the island of Trinidad, the Southern Range is a discontinuous chain of low hills along the southern coast, reaching their highest altitude in the 1,000 feet (300 m) high Trinity Hills of the southeast. According to legend, the sight of the three neighboring hilltops of the then unnamed Trinity Hills, led to Christopher Columbus, on his third voyage to the New World, to name the island, "Trinidad." The broad lowland area on the west between the Southern Range and the Central Range is the Naparima Plain; the lowland area on the east is the Nariva Plain. The Oropuche river flows through the Naparima Plain and drains into the Oropuche Lagoon, a swampy area, on the Gulf of Paria coast, whereas the 31-mile long Ortoire River flows through the Nariva Plain and drains into the Nariva Swamp on the Atlantic Ocean coast. The Southern region of the island has sandy and less fertile soil. The Southern Range, particularly its Western and Central parts, consists of unconsolidated segments.
The Trinidad mangroves ecoregion covers the separate mangrove forest areas on the coast of the island of Trinidad, in the country of Trinidad and Tobago. The character of the mangroves is affected by the large amount of fresh water flowing out of the Orinoco River and Amazon River to the south, which flow northwest around the island. The mangroves of Trinidad are found on all coasts, and are usually in the estuaries of rivers, but also found in coastal lagoons.
