Decalobanthus peltatus is a species of flowering vine in the morning glory family, Convolvulaceae, that is native to Pemba Island, the Mascarene Islands, Madagascar, the Seychelles, Indonesia, Malaysia, the Philippines, northern Queensland (Australia) and French Polynesia. [1] It has been introduced and subsequently become invasive on some of the other Pacific islands, such as New Caledonia, Samoa, Fiji, Solomon Islands, and Palau. [2] [3] [4] [5]
As an invasive species in island habitats, Decalobanthus peltatus can completely cover trees, smothering and killing large areas of native forest; the resulting death of trees and loss of forests can cause less food for native birds and fruit bats and can also increase soil erosion, leading to increased sedimentation and death of coral reefs. [5]
For eradication of invasive populations, cutting the vines at the base will kill the tops and allow trees to recover. The vines will re-grow from the base, so it is best to uproot them if possible, but repeated cutting will exhaust and eventually kill the vines. [5] The vine's seeds will not germinate in the shade, so the best way to prevent invasive problems with this vine is to keep native forest intact. [5]
In Palau, where it is locally referred to by the name kebeas, public efforts have been taken to promote physical fitness and ecology by encouraging the community to use machetes to cut the vine. [4] [5]
Kudzu, also called Japanese arrowroot or Chinese arrowroot, is a group of climbing, coiling, and trailing deciduous perennial vines native to much of East Asia, Southeast Asia, and some Pacific islands. It is invasive in many parts of the world, primarily North America.
An invasive species is an introduced species that harms its new environment. 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 web. Since the 20th century, invasive species have become serious economic, social, and environmental threats worldwide.
Epipremnum aureum is a species in the arum family Araceae, native to Mo'orea in the Society Islands of French Polynesia. The species is a popular houseplant in temperate regions but has also become naturalised in tropical and sub-tropical forests worldwide, including northern South Africa, Australia, Southeast Asia, Indian subcontinent, the Pacific Islands and the West Indies, where it has caused severe ecological damage in some cases.
Pueraria montana is a species of plant in the botanical family Fabaceae. At least three sub-species are known. It is closely related to other species in the genus Pueraria and the common name kudzu is used for all of these species and hybrids between them. The morphological differences between them are subtle, they can breed with each other, and it appears that introduced kudzu populations in the United States have ancestry from more than one of the species.
The yellow crazy ant, also known as the long-legged ant or Maldive ant, is a species of ant, thought to be native to West Africa or Asia. They have been accidentally introduced to numerous places in the world's tropics.
Arbutus menziesii, or Pacific madrone, is a species of broadleaf evergreen tree in the family Ericaceae. It has waxy foliage, a contorted growth habit, and flaky bark.
Acer macrophyllum, the bigleaf maple or Oregon maple, is a large deciduous tree in the genus Acer. It is native to western North America. In addition to uses by animals, it is of some culinary and woodworking interest.
Pandanus tectorius is a species of Pandanus (screwpine) that is native to Malesia, Papuasia, eastern Australia, and the Pacific Islands. It grows in the coastal lowlands typically near the edge of the ocean. Common names in English include thatch screwpine, Tahitian screwpine, hala tree and pandanus. The fruit is edible and sometimes known as hala fruit.
Forest integrated pest management or Forest IPM is the practice of monitoring and managing pest and environmental information with pest control methods to prevent pest damage to forests and forest habitats by the most economical means.
Prosopis pallida is a species of mesquite tree. It has the common names kiawe, huarango and American carob, as well as "bayahonda", "algarrobo pálido", and "algarrobo blanco". It is a thorny legume, native to Colombia, Ecuador and Peru, particularly drier areas near the coast. While threatened in its native habitat, it is considered an invasive species in many other places.
Anredera cordifolia, commonly known as the Madeira vine or mignonette vine, is a South American species of ornamental succulent vine of the family Basellaceae. The combination of fleshy leaves and thick aerial tubers makes this a very heavy vine. It smothers trees and other vegetation it grows on and can easily break branches and bring down entire trees on its own. Other names include lamb's tail and potato vine.
Tecoma stans is a species of flowering perennial shrub in the trumpet vine family, Bignoniaceae, that is native to the Americas. Common names include yellow trumpetbush, yellow bells, yellow elder, ginger Thomas. Tecoma stans is the official flower of the United States Virgin Islands and the floral emblem of The Bahamas.
Ipomoea indica is a species of flowering plant in the family Convolvulaceae, known by several common names, including blue morning glory, oceanblue morning glory, koali awa, and blue dawn flower. It bears heart-shaped or three-lobed leaves and purple or blue funnel-shaped flowers 6–8 cm (2–3 in) in diameter, from spring to autumn. The flowers produced by the plant are hermaphroditic. This plant has gained the Royal Horticultural Society's Award of Garden Merit.
Genetic pollution is a term for uncontrolled gene flow into wild populations. It is defined as "the dispersal of contaminated altered genes from genetically engineered organisms to natural organisms, esp. by cross-pollination", but has come to be used in some broader ways. It is related to the population genetics concept of gene flow, and genetic rescue, which is genetic material intentionally introduced to increase the fitness of a population. It is called genetic pollution when it negatively impacts the fitness of a population, such as through outbreeding depression and the introduction of unwanted phenotypes which can lead to extinction.
Clerodendrum quadriloculare is a species of flowering plant native to New Guinea and the Philippines. It is one of many species previously included in the family Verbenaceae, but transferred to the Lamiaceae based on molecular studies. The plants produce flowers which look good in a garden, but it can be difficult to eradicate.
Antigonon leptopus is a species of perennial vine in the buckwheat family commonly known as coral vine or queen's wreath. This clambering vine is characterized by showy, usually pink flowers that can bloom throughout the year and large, heart-shaped leaves. A. leptopus is native to the Pacific and Atlantic coastal plains of Mexico, but also occurs as a roadside weed from Mexico south to Central America. It is widely introduced and invasive throughout tropical regions of the world, including in the south and eastern United States, the West Indies, South America, and the Old World tropics of Asia and Africa. This species is utilized for its edible tubers and seeds, but also for its horticultural properties as an ornamental vine in warmer parts of the world.
Mycoforestry is an ecological forest management system implemented to enhance forest ecosystems and plant communities, by introducing the mycorrhizal and saprotrophic fungi. Mycoforestry is considered a type of permaculture and can be implemented as a beneficial component of an agroforestry system. It can enhance the yields of tree crops and produce edible mushrooms, an economically valuable product. By integrating plant-fungal associations into a forestry management system, native forests can be preserved, wood waste can be recycled back into the ecosystem, carbon sequestration can be increased, planted restoration sites are enhanced, and the sustainability of forest ecosystems are improved. Mycoforestry is an alternative to the practice of clearcutting, which removes dead wood from forests, thereby diminishing nutrient availability and reducing soil depth.
Invasive species are a crucial threat to many native habitats and species of the United States and a significant cost to agriculture, forestry, and recreation. An invasive species refers to an organism that is not native to a specific region and poses significant economic and environmental threats to its new habitat. The term "invasive species" can also refer to feral species or introduced diseases. Some introduced species, such as the dandelion, do not cause significant economic or ecologic damage and are not widely considered as invasive. Economic damages associated with invasive species' effects and control costs are estimated at $120 billion per year.
Kudzu is an invasive plant species in the United States, introduced from Asia with devastating environmental consequences, earning it the nickname "the vine that ate the South". It has been spreading rapidly in the Southern United States, "easily outpacing the use of herbicide, spraying, and mowing, as well increasing the costs of these controls by $6 million annually". Estimates of the vine's spread vary, from the United States Forest Service's 2015 estimate of 2,500 acres per year to the Department of Agriculture's estimate of as much as 150,000 acres annually.
Terminalia richii, with the common name malili, is an upright forest tree species native to the central South Pacific in Oceania.
