This is a timeline of environmental history of New Zealand. It includes notable events affecting the natural environment of New Zealand as a result of human activity.
Wakame(Undaria pinnatifida) is a species of kelp native to cold, temperate coasts of the northwest Pacific Ocean. As an edible seaweed, it has a subtly sweet, but distinctive and strong flavour and texture. It is most often served in soups and salads.
Invasive species in Australia are a serious threat to the native biodiversity, and an ongoing cost to Australian agriculture. Numerous species arrived with European maritime exploration and colonisation of Australia and steadily since then.
A number of introduced species, some of which have become invasive species, have been added to New Zealand's native flora and fauna. Both deliberate and accidental introductions have been made from the time of the first human settlement, with several waves of Polynesian people at some time before the year 1300, followed by Europeans after 1769.
Conservation in New Zealand has a history associated with both Māori and Europeans. Both groups of people caused a loss of species and both altered their behaviour to a degree after realising their effect on indigenous flora and fauna.
Tradescantia fluminensis is a species of spiderwort native to South America. It is one of several plants known by the common name wandering Jew. It is also known as small-leaf spiderwort, river spiderwort, inch plant, speedy Henry, wandering willie and wandering trad.
A noxious weed, harmful weed or injurious weed is a weed that has been designated by an agricultural or other governing authority as a plant that is injurious to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock. Most noxious weeds have been introduced into an ecosystem by ignorance, mismanagement, or accident. Some noxious weeds are native. Typically they are plants that grow aggressively, multiply quickly without natural controls, and display adverse effects through contact or ingestion. Noxious weeds are a large problem in many parts of the world, greatly affecting areas of agriculture, forest management, nature reserves, parks and other open space.
Gunnera tinctoria, known as giant rhubarb, Chilean rhubarb, or nalca, is a flowering plant species native to southern Chile and neighboring zones in Argentina. It is unrelated to rhubarb, as the two plants belong to different orders, but looks similar from a distance and has similar culinary uses. It is a large-leaved perennial plant that grows to more than two metres tall. It has been introduced to many parts of the world as an ornamental plant. In some countries, such as New Zealand, the United Kingdom and Ireland, it has spread from gardens and is becoming an introduced species of concern. It is known under the synonyms: Gunnera chilensis Lam. and Gunnera scabra Ruiz & Pav.
Asparagus asparagoides, commonly known as bridal creeper, bridal-veil creeper, gnarboola, smilax or smilax asparagus, is a herbaceous climbing plant of the family Asparagaceae native to eastern and southern Africa. Sometimes grown as an ornamental plant, it has become a serious environmental weed in Australia and New Zealand.
Wilding conifers, also known as wilding pines, are invasive trees in the high country of New Zealand. Millions of dollars are spent on controlling their spread.
Nassella trichotoma, the serrated tussock, is a type of bunchgrass plant, native in Argentina, Uruguay, Chile, and Peru.
1080, the brand name given to the synthetic form of sodium fluoroacetate, is used in New Zealand in efforts to control populations of possums, rats, stoat and rabbits, which are invasive species in the New Zealand environment. Although the Parliamentary Commissioner for the Environment deemed the use of 1080 in New Zealand "effective and safe" in a 2011 re-evaluation and the substance is widely considered to be the most effective tool currently available for controlling possums over large areas, it remains a contentious issue, with the majority of the debate occurring between conservationists and livestock farmers on one side and hunters and animal-rights activists on the other.
Biosecurity Act 1993 is an Act of Parliament in New Zealand. The Act is a restatement and reform of the laws relating to pests and other unwanted organisms. It was a world first.
The common brushtail possum was introduced from Australia to New Zealand, where it has become invasive and a major agricultural and conservation pest.
Invasive species are a significant threat to many native habitats and species of the United States and a significant cost to agriculture, forestry, and recreation. The term "invasive species" can refer to introduced/naturalized species, 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.
Old man's beard is an invasive plant in New Zealand that affects indigenous biodiversity. It is declared an unwanted organism under the Biosecurity Act 1993 which means it cannot be sold, distributed or propagated.
Biosecurity in New Zealand guards against threats to agriculture and biodiversity, with strict border control measures being taken to prevent unwanted organisms from entering the country. New Zealand is an island nation that is geographically isolated from any other significant landmass. The species that are present evolved in the absence of organisms from elsewhere and display a high degree of endemism. Notable is the lack of land-based mammals, except for two species of bat. Indigenous species are at risk from population decline or extinction if any invasive species are introduced.
National biosecurity in Australia is governed and administered by two federal government departments, the Department of Health and the Department of Agriculture, Fisheries and Forestry. The Biosecurity Act 2015 (C'wealth) and related legislation is administered by the two departments and manages biosecurity risks at the national border. The Act aims to manage biosecurity risks to human health, agriculture, native flora and fauna and the environment. It also covers Australia's international rights and obligations, and lists specific diseases which are contagious and capable of causing severe harm to human health. Each state and territory has additional legislation and protocols to cover biosecurity in their jurisdiction (post-border) including the detection of pests and diseases that have breached the national border.
Originating from South Africa, Agapanthus-- specifically Agapanthus praecox and its cultivars -- were brought to New Zealand and later became a popular and common invasive species garden plant.
The Invasive Species Council is an Australian environmental non-governmental organisation founded in 2002 to provide a specialist policy and advocacy focus on reducing the threat of invasive species that threaten the environment.
