Witch-hazels ("Hamamelis," ) are a genus of flowering plants in the family Hamamelidaceae, with four species in North America ("H. mexicana", "H. ovalis", "H. virginiana", and "H. vernalis"), and one each in Japan ("H. japonica") and China ("H. mollis").
 The North American species are occasionally called winterbloom.
Broussonetia is a genus of four species of trees in the family Moraceae, native to eastern Asia.
 One of these is the paper mulberry "(Broussonetia papyrifera)", whose bark fiber is used to make high-quality paper, in China, Korea and Japan.
 This species has been widely introduced and has become invasive in some areas.
Wasps of the cosmopolitan genus Polistes (the only genus in the tribe Polistini) are the most familiar of the polistine wasps, and are the most common type of paper wasp in North America.
 It is also the single largest genus within the family Vespidae, with over 300 recognized species and subspecies.
 Their innate preferences for nest-building sites leads them to commonly build nests on human habitation, where they can be very unwelcome; although generally not aggressive, they can be provoked into defending their nests.
 All species are predatory, and they may consume large numbers of caterpillars, in which respect they are generally considered beneficial.
 The European paper wasp, "Polistes dominula", was introduced into the US about 1981 and has quickly spread throughout most of the country, in most cases replacing native species within a few years.
 This species is very commonly mistaken for a yellow jacket, as it is black, strongly marked with yellow, and quite different from the native North American species of "Polistes".
 The cuckoo wasp, "Polistes sulcifer", is an obligate social parasite, whose only host is "P. dominula". "
Polistes annularis", whose species name is Latin for "ringed", is also known for its distinctive red body color. "
Polistes metricus" adults malaxate their insect prey by chewing them into a pulp, sucking out and ingesting the body fluids, then feeding the rest of the morsel to their larvae.
 The most widely distributed South American wasp species, "Polistes versicolor", is particularly common in the southeastern Brazilian states.
 This social wasp is commonly referred to as the yellow paper wasp due to the distinct yellow bands found on its thorax and abdomen.
 "Polistes" wasps can be identified by their characteristic flight; their long legs dangle below their bodies, which are also more slender than a yellow jacket.
The cane toad in Australia is regarded as an exemplary case of a "feral species"—others being rabbits, foxes, cats, dogs and giant mimosa.
 Australia's relative isolation prior to European colonisation and the industrial revolution—both of which dramatically increased traffic and importation of novel species—allowed development of a complex, interdepending system of ecology, but one which provided no natural predators for many of the species subsequently introduced.
 The recent, sudden inundation of foreign species has led to severe breakdowns in Australian ecology, after overwhelming proliferation of a number of introduced species for which the continent has no efficient natural predator or parasite, and which displace native species—in some cases these species are physically destructive to habitat as well.
 Cane toads have been very successful as an invasive species, having become established in more than 15 countries within the past 150 years.
 In the Environment Protection and Biodiversity Conservation Act 1999, the Australian Government listed the impacts of the cane toad as a "key threatening process".
Anthemis cotula, also known as stinking chamomile, is a flowering annual plant with a noticeable and strong odor.
 The odor is often considered unpleasant, and it is from this that it gains the common epithet "stinking".
 In pre-colonial times, its distribution was limited to the Old Continent (though it was most of Europe, nd were not present in Finland, Ireland, and the Northernmost Scotland, both these countries with many favorable climates to this plant and to be neighbors to countries that owned this plant like native species, such example Russia, Estonia, Lithuania and England) and to Africa.
 It has successfully migrated to the New Europes where it can be found growing on waste ground, alongside roads, and in fields.
 "Anthemis cotula" is considered a weed due to its propensity for invading cultivated areas.
Invasive species are a serious threat to the native biodiversity of South America and are an ongoing cost to South American agriculture.
 South America is an important region for the worlds biodiversity, and includes a wide variety of native species, many of which provide .
 Introduced species in South America, have the potential to pose harm to ecosystems of the region and the aforementioned biodiversity.
 Although many of these non-native species are invasive, residents of the region often value these species, making it more difficult to organize efforts to get rid of them.
 Because of the instrumental and cultural value placed on these species, greater awareness, research, and policy are all necessary steps in solving invasive issues in South America.
 Here is a list of just a few of the species that have invaded South America and where they originate.
The U.S. state of alabama is home to these known indigenous mammal species.
 Historically, the state's indigenous species included one armadillo species, sixteen bat species, thirteen carnivore species, six insectivore species, one opossum species, four rabbit species, twenty-two rodent species, and three ungulate species.
 Four of these native species have become extirpated within the state, including the American bison, cougar, elk, and the red wolf.
Hedgehog Street is a UK-based conservation initiative set up by two charitable organisations, the People's Trust for Endangered Species (PTES) and the British Hedgehog Preservation Society (BHPS).
 The project was established in 2011 in response to a detected decline in the hedgehog ("Erinaceus europaeus") population in Britain, where it is a native species.
 Hedgehog Street is based around a website that provides volunteers with information about the ecology and behaviour of this mammal, tips on ways of managing gardens to benefit it, and resources to encourage volunteers to recruit other people to participate.
 The ultimate goal of the site is to encourage people to cooperatively develop interconnected networks of gardens that are managed in a way that benefits hedgehogs, and the other native species associated with these habitats. Users (or “Hedgehog Champions”) can also log into a members area where they can upload photos and access forums.
 As of December 2014 there were more than 32,000 volunteers registered through the website.
Cornus is a genus of about 30–60 species of woody plants in the family Cornaceae, commonly known as dogwoods, which can generally be distinguished by their blossoms, berries, and distinctive bark.
 Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and a few of the woody species are evergreen.
 Several species have small heads of inconspicuous flowers surrounded by an involucre of large, typically white petal-like bracts, while others have more open clusters of petal-bearing flowers.
 The various species of dogwood are native throughout much of temperate and boreal Eurasia and North America, with China and Japan and the southeastern United States particularly rich in native species.
Hamamelis virginiana, known as common or American witch-hazel, is a species of witch-hazel native to eastern North America, from Nova Scotia west to Minnesota, and south to central Florida to eastern Texas.
