In chemistry, cyanide is a chemical compound that contains a C≡N functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom.
Feral pigeons, also called city doves, city pigeons, or street pigeons, are descendants of domestic pigeons that have returned to the wild. The domestic pigeon was originally bred from the wild rock dove, which naturally inhabits sea-cliffs and mountains. Rock, domestic, and feral pigeons are all the same species and will readily interbreed. Feral pigeons find the ledges of buildings to be a substitute for sea cliffs, have become adapted to urban life, and are abundant in towns and cities throughout much of the world.
Sodium nitrite is an inorganic compound with the chemical formula NaNO2. It is a white to slightly yellowish crystalline powder that is very soluble in water and is hygroscopic. From an industrial perspective, it is the most important nitrite salt. It is a precursor to a variety of organic compounds, such as pharmaceuticals, dyes, and pesticides, but it is probably best known as a food additive used in processed meats and in fish products.
Molluscicides – also known as snail baits, snail pellets, or slug pellets – are pesticides against molluscs, which are usually used in agriculture or gardening, in order to control gastropod pests specifically slugs and snails which damage crops or other valued plants by feeding on them.
A feral cat or a stray cat is an unowned domestic cat that lives outdoors and avoids human contact; it does not allow itself to be handled or touched, and usually remains hidden from humans. Feral cats may breed over dozens of generations and become a local apex predator in urban, savannah and bushland environments, and especially on islands where native animals did not evolve alongside predators. Some feral cats may become more comfortable with people who regularly feed them, but even with long-term attempts at socialization, they usually remain aloof and reject human touch. Of the 700 million cats in the world, an estimated 480 million are feral.
Rodenticides are chemicals made and sold for the purpose of killing rodents. While commonly referred to as "rat poison", rodenticides are also used to kill mice, woodchucks, chipmunks, porcupines, nutria, beavers, and voles. Despite the crucial roles that rodents play in nature, there are times when they need to be controlled.
Sodium fluoroacetate, also known as compound 1080, is an organofluorine chemical compound with the chemical formula FCH2CO2Na. It is the sodium salt of fluoroacetic acid. It contains sodium cations Na+ and fluoroacetate anions FCH2CO−2. This colourless salt has a taste similar to that of table salt and is used as a rodenticide.
The ecological restoration of islands, or island restoration, is the application of the principles of ecological restoration to islands and island groups. Islands, due to their isolation, are home to many of the world's endemic species, as well as important breeding grounds for seabirds and some marine mammals. Their ecosystems are also very vulnerable to human disturbance and particularly to introduced species, due to their small size. Island groups, such as New Zealand and Hawaii, have undergone substantial extinctions and losses of habitat. Since the 1950s several organisations and government agencies around the world have worked to restore islands to their original states; New Zealand has used them to hold natural populations of species that would otherwise be unable to survive in the wild. The principal components of island restoration are the removal of introduced species and the reintroduction of native species.
The farm cat, also known as a barn cat, is a domestic cat, usually of mixed breed, that lives primarily outdoors, in a feral or semi-feral condition on agricultural properties, usually sheltering in outbuildings. They eat assorted vermin such as rodents and other small animals that live in or around outbuildings and farm fields.
Western Shield, managed by Western Australia's Department of Parks and Wildlife, is a nature conservation program safeguarding Western Australia's animals and protecting them from extinction. The program was set up in 1996 and as of 2009 was the largest and most successful wildlife conservation program ever undertaken in Australia.
Brodifacoum is a highly lethal 4-hydroxycoumarin vitamin K antagonist anticoagulant poison. In recent years, it has become one of the world's most widely used pesticides. It is typically used as a rodenticide, but is also used to control larger pests such as possums.
The M44 cyanide device is used to kill coyotes, feral dogs, and foxes. It is made from four parts: a capsule holder wrapped with cloth or other soft material, a small plastic capsule containing 0.88 grams of sodium cyanide, a spring-powered ejector, and a 5–7 inches (130–180 mm) stake. To install the trap, the stake is first driven down into the ground, and then the capsule is put in the holder, screwed onto the cocked ejector, and secured to the stake. The wrapped capsule holder is smeared with scented bait to attract coyotes and make them bite and pull on it. When the trap is triggered, the spring propels a dose of sodium cyanide into the animal's mouth, and the sodium cyanide combines with water in the mouth to produce poisonous cyanide gas. In addition to the cyanide, the capsule contains a brightly-colored particle marker.
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.
The stoat was introduced into New Zealand to control introduced rabbits and hares, but is now a major threat to the native bird population. The natural range of the stoat is limited to parts of the Northern Hemisphere. Immediately before human settlement, New Zealand did not have any land-based mammals apart from bats, but Polynesian and European settlers introduced a wide variety of animals. Rarely, in Southland, the fur of stoats has been reported to turn white, being the fur known as ermine, which adorns royal robes.
Cats are a popular pet in New Zealand. Cat ownership is occasionally raised as a controversial conservation issue due to the predation of endangered species, such as birds and lizards, by feral cats.
Victoria Forest Park, is situated on the West Coast of the South Island of New Zealand. At 2,069 square kilometres (799 sq mi) it is New Zealand's largest forest park. The park is administered by the Department of Conservation (DOC).
Cat predation on wildlife is the result of the natural instincts and behavior of both feral and owned house cats to hunt small prey, including wildlife. Some people view this as a desirable trait, such as in the case of barn cats and other cats kept for the intended purpose of pest control in rural settings; but scientific evidence does not support the popular use of cats to control urban rat populations, and ecologists oppose their use for this purpose because of the disproportionate harm they do to native wildlife. Recognized as both invasive species and predators, cats have been shown to cause significant ecological harm across various ecosystems.
Predator Free 2050 is a plan put forth by the New Zealand government with the goal of eradicating all of its mammalian introduced predators by 2050.
Heirisson Prong is a community managed reserve established for the conservation of threatened mammals at Shark Bay in Western Australia. The reserve is at the point of a long narrow peninsula of the same name that juts into Shark Bay from the south.
In biology, overabundant species refers to an excessive number of individuals and occurs when the normal population density has been exceeded. Increase in animal populations is influenced by a variety of factors, some of which include habitat destruction or augmentation by human activity, the introduction of invasive species and the reintroduction of threatened species to protected reserves.
