Mount Sage
Mount Sage National Park is a protected area of the British Virgin Islands. It is named after the highest peak of the island of Tortola, Mount Sage. The Mount Sage volcanic peak rises to a height of , and is thus the highest point in all of the Virgin Islands. The park is located to the southwest of the island group's capital, Road Town. The park, which includes the mountain range, extends over an area of . The vegetation is of semi-rain forest type. There are many trails for trekking and hiking. History The national park was established in 1964, covering an area of 35 ha. It was the first national park in the British Virgin Islands to preserve and reserve the remaining forests and its adjoining watershed areas. The reserve area was acquired from private farmers by the Government with a grant provided by Laurance Rockefeller, and was given to the National Park Trust in 1964 for making it a forest reserve for conservation purposes. Geography Approach to the national park is from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Town
Road Town, located on Tortola, is the capital of the British Virgin Islands. It is situated on the horseshoe-shaped Road Harbour in the centre of the island's south coast. The population was about 15,000 in 2018. The name is derived from the nautical term "the roads", a place less sheltered than a harbour but which ships can easily get to. A development called Wickham's Cay, consisting of two areas that were reclaimed from the sea and a marina, have enabled Road Town to emerge as a haven for yacht chartering and a centre of tourism. This area is the newest part of the city and the hub for the new commercial and administrative buildings of the BVI. The oldest building in Road Town, HM Prison on Main Street, was built in 1774. Climate The British Virgin Islands enjoy a tropical climate, moderated by trade winds. Temperatures vary little throughout the year. In the capital, Road Town, typical daily maxima are around in the summer and in the winter. Typical daily minima are aro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epiphytes
An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Kestrel
The American kestrel (''Falco sparverius''), also called the sparrow hawk, is the smallest and most common falcon in North America. It has a roughly two-to-one range in size over subspecies and sex, varying in size from about the weight of a blue jay to a mourning dove. It also ranges to South America and is a well-established species that has evolved into 17 subspecies adapted to different environments and habitats throughout the Americas. It exhibits sexual dimorphism in size (females being moderately larger) and plumage, although both sexes have a rufous back with noticeable barring. Its plumage is colorful and attractive, and juveniles are similar in plumage to adults. The American kestrel usually hunts in energy-conserving fashion by perching and scanning the ground for prey to ambush, though it also hunts from the air. It sometimes hovers in the air with rapid wing beats while homing in on prey. Its diet typically consists of grasshoppers and other insects, lizards, m ...

Hermit Crab
Hermit crabs are anomuran decapod crustaceans of the superfamily Paguroidea that have adapted to occupy empty scavenged mollusc shells to protect their fragile exoskeletons. There are over 800 species of hermit crab, most of which possess an asymmetric abdomen concealed by a snug-fitting shell. Hermit crabs' soft (non-calcified) abdominal exoskeleton means they must occupy shelter produced by other organisms or risk being defenseless. The strong association between hermit crabs and their shelters has significantly influenced their biology. Almost 800 species carry mobile shelters (most often calcified snail shells); this protective mobility contributes to the diversity and multitude of crustaceans found in almost all marine environments. In most species, development involves metamorphosis from symmetric, free-swimming larvae to morphologically asymmetric, benthic-dwelling, shell-seeking crabs. Such physiological and behavioral extremes facilitate a transition to a sheltered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heliconia
''Heliconia'', derived from the Greek word (), is a genus of flowering plants in the monotypic family Heliconiaceae. Most of the ca 194 known species are native to the tropical Americas, but a few are indigenous to certain islands of the western Pacific and Maluku. Many species of ''Heliconia'' are found in the tropical forests of these regions. Most species are listed as either vulnerable or data deficient by the IUCN Red List of threatened species. Several species are widely cultivated as ornamentals, and a few are naturalized in Florida, Gambia, and Thailand. Common names for the genus include lobster-claws, toucan beak, wild plantain, or false bird-of-paradise. The last term refers to their close similarity to the bird-of-paradise flowers ('' Strelitzia''). Collectively, these plants are also simply referred to as "heliconias". Description These herbaceous plants range from 0.5 to nearly 4.5 m (1.5–15 ft) tall, depending on the species. The simple leaves of thes ...

Mammea Americana
''Mammea americana'', commonly known as mammee, mammee apple, mamey, mamey apple, Santo Domingo apricot, tropical apricot, or South American apricot, is an evergreen tree of the family Calophyllaceae, whose fruit is edible. It has also been classified as belonging to the family Guttiferae Juss. (1789), which would make it a relative of the mangosteen. In certain Latin American countries, ''Mammea americana'' is referred to as "yellow mamey" ( es, mamey amarillo) to distinguish it from the unrelated but similar-looking ''Pouteria sapota'', whose fruit is usually called "red mamey" ( or ). Description Tree The mammee tree is high and is similar in appearance to the southern magnolia ''(Magnolia grandiflora)''. Its trunk is short and reaches in diameter. The tree's upright branches form an oval head. Its dark-green foliage is quite dense, with opposite, leathery, elliptical leaves. The leaves can reach wide and twice as long. The mammee flower is fragrant, has four or six ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psidium
''Psidium'' is a genus of trees and shrubs in the family Myrtaceae. It is native to warmer parts of the Western Hemisphere (Mexico, Central and South America, the West Indies the Galápagos islands). Taxonomy This genus was described first by Linnaeus in 1753. Many of the species bear edible fruits, and for this reason several are cultivated commercially. The most popularly cultivated species is the common guava, ''Psidium guajava.''

Manilkara
''Manilkara'' is a genus of trees in the family Sapotaceae. They are widespread in tropical and semitropical locations, in Africa, Madagascar, Asia, Australia, and Latin America, as well as various islands in the Pacific and in the Caribbean. A close relative is the genus ''Pouteria''. Trees of this genus yield edible fruit, useful wood, and latex. The best-known species are '' M. bidentata'' (''balatá''), '' M. chicle'' (chicle) and '' M. zapota'' (sapodilla). ''M. hexandra'' is the floral emblem of Prachuap Khiri Khan Province in Thailand, where it is known as ''rayan''. ''M. obovata'' shares the vernacular name of African pear with another completely different species, '' Dacryodes edulis'', and neither should be confused with '' Baillonella toxisperma'', known by the very similar name, African pearwood. The generic name, ''Manilkara'', is derived from ''manil-kara'', a vernacular name for '' M. kauki'' in Malayalam. ''Manilkara'' trees are often significant, or even do ...

Tree Fern
The tree ferns are arborescent (tree-like) ferns that grow with a trunk elevating the fronds above ground level, making them trees. Many extant tree ferns are members of the order Cyatheales, to which belong the families Cyatheaceae (scaly tree ferns), Dicksoniaceae, Metaxyaceae, and Cibotiaceae. It is estimated that Cyatheales originated in the early Jurassic, and is the third group of ferns known to have given rise to tree-like forms. The others are the extinct '' Tempskya'' of uncertain position, and Osmundales where the extinct Guaireaceae and some members of Osmundaceae also grew into trees. In addition there were the Psaroniaceae and Tietea in the Marattiales, which is the sister group to most living ferns including Cyatheales. Other ferns which are also tree ferns, are ''Leptopteris'' and ''Todea'' in the family Osmundaceae, which can achieve short trunks under a metre tall. Fern species with short trunks in the genera ''Blechnum'', '' Cystodium'' and ''Sadleria'' from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tabebuia
''Tabebuia'' is a genus of flowering plants in the family Bignoniaceae.Eberhard Fischer, Inge Theisen, and Lúcia G. Lohmann. 2004. "Bignoniaceae". pages 9-38. In: Klaus Kubitzki (editor) and Joachim W. Kadereit (volume editor). ''The Families and Genera of Vascular Plants'' volume VII. Springer-Verlag: Berlin; Heidelberg, Germany. The common name "roble" is sometimes found in English. ''Tabebuias'' have been called "trumpet trees", but this name is usually applied to other trees and has become a source of confusion and misidentification. ''Tabebuia'' consists almost entirely of trees, but a few are often large shrubs. A few species produce timber, but the genus is mostly known for those that are cultivated as flowering trees.David J. Mabberley. 2008. ''Mabberley's Plant-Book'' third edition (2008). Cambridge University Press: UK.
