Elaeodendron Laneanum
''Elaeodendron laneanum'', commonly known as the Bermuda olivewood, is a species of tree in the family Celastraceae that is endemic to Bermuda. It is considered an endangered species. Distribution and habitat Endemic to Bermuda, ''E. laneanum'' has a patchy distribution across the main island. The original habitat of this species, forested valleys and hillsides, has largely been cleared for agriculture. The remaining natural range of this species can mainly be found in Walsingham Tract, however, it is widely used as an ornamental plant and can be found in parks and gardens across Bermuda. Description ''Elaeodendron laneanum'' is an evergreen tree growing tall with a smooth, stout trunk up to in diameter. The leaves are glossy above with a toothed margin, light green when young and darkening as they mature. The flowers are small, greenish-white in colour, and occur in clusters at the tips of branches and develop into small yellowish-green fruits. Conservation status ''E. lanea ...

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images.

Endangered Plants
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 3654 endangered plant species. 17% of all evaluated plant species are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of exintction". An even higher risk is faced by ''critically endangered'' species, which meet the quantitative criteria for endangered species. Critically endangered plants are listed separately. There are 6147 plant species which are endangered or critically endangered. Additionally 1674 plant species (7.6% of those evaluated) are listed as ''data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of Bermuda
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hamilton, Bermuda
The City of Hamilton, in Pembroke Parish, is the territorial capital of the British Overseas Territory of Bermuda. It is the territory's financial centre and a major port and tourist destination. Its population of 854 (2016) is one of the smallest of any capital city. History The history of Hamilton as a British city began in 1790 when the government of Bermuda set aside for its future seat, officially incorporated in 1793 by an Act of Parliament, and named for Governor Henry Hamilton. The colony's capital relocated to Hamilton from St George's in 1815. The city has been at the political and military heart of Bermuda ever since. Government buildings include the parliament building, the Government House to the north, the former Admiralty House of the Royal Navy to the west (both in Pembroke), and the British Army garrison headquarters at Prospect Camp to its east. The Town of Hamilton became a city in 1897, ahead of the consecration in 1911 of the Cathedral of the M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Street Tree
Urban forestry is the care and management of single trees and tree populations in urban settings for the purpose of improving the urban environment. Urban forestry involves both planning and management, including the programming of care and maintenance operations of the urban forest. Urban forestry advocates the role of trees as a critical part of the urban infrastructure. Urban foresters plant and maintain trees, support appropriate tree and forest preservation, conduct research and promote the many benefits trees provide. Urban forestry is practiced by municipal and commercial arborists, municipal and utility foresters, environmental policymakers, city planners, consultants, educators, researchers and community activists. Benefits Environmental and health impacts Heat waves cause 1,300 deaths each year in the United States alone, which is more than any other weather-related event. As temperatures continue to rise due to global warming, we can expect to see this numbe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nonsuch Island
Nonsuch Island (originally Nonesuch Island) is part of the chain of islands which make up Bermuda. It is in St George's Parish, in the northeast of Bermuda. It is 5.7 ha (14 acres) in area and is at the east entrance to Castle Harbour, close to the south-easternmost point of Cooper's Island (now ostensibly part of the much larger St David's Island). Among the island's charted features is a bay called Nonsuch Bay. History In 1865 it served as a yellow fever quarantine hospital. On the eastern part of the island there still remains a small cemetery. In 1930 it served as a base for William Beebe and Otis Barton's landmark bathysphere dive. Environment The island is a wildlife sanctuary. It is wooded and with a small freshwater marsh, access to the public is strictly limited. The restoration of the once barren island into a 'Living Museum of pre-colonial Bermuda' is the lifetime work of now retired Bermudian ornithologist and conservationist David B. Wingate, and part of his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Regeneration
Regeneration is the ability for a cell, tissue, or organism to recover from damage. It can also be used to describe the ability of an ecosystemspecifically, the environment and its living populationto renew and recover from damage. Regeneration refers to ecosystems replenishing what is being eaten, disturbed, or harvested. Regeneration's biggest force is photosynthesis which transforms sun energy and nutrients into plant biomass. Resilience to minor disturbances is one characteristic feature of healthy ecosystems. Following major (lethal) disturbances, such as a fire or pest outbreak in a forest, an immediate return to the previous dynamic equilibrium will not be possible. Instead, pioneering species will occupy, compete for space, and establish themselves in the newly opened habitat. The new growth of seedlings and community assembly process is known as regeneration in ecology. As ecological succession sets in, a forest will slowly regenerate towards its former state within th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin ('' Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter ('' Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range ...

Habitat Fragmentation
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment (suspected of being one of the major causes of speciation), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats. Definition The term habitat fragmentation includes five discrete phenomena: * Reduction in the total area of the habitat * Decrease of the interior: edge ratio * Isolation of one habitat fragment from other areas of habitat * Breaking up of one patch of habitat into several smaller patches * Decrease in the average size of each patch of hab ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
