Headstarting

Last updated

Headstarting is a conservation technique for endangered species, in which young animals are raised artificially and subsequently released into the wild. The technique allows a greater proportion of the young to reach independence, without predation or loss to other natural causes. [1] [2] [3] [4]

For endangered birds and reptiles, eggs are collected from the wild are hatched using an incubator. [1] [2] For mammals such as Hawaiian monk seals, the young are removed from their mothers after weaning. [5]

The technique was trialled on land-based mammals for the first time in Australia. In the three years prior to May 2021, young bridled nail-tail wallabies were placed in a fenced-off area of 10-hectare (25-acre) area within Avocet Nature Refuge in Queensland. The population, safe from their main predator, feral cats, more than doubled over this period. [6]

A wallaby is a small or middle-sized macropod native to Australia and New Guinea, with introduced populations in New Zealand, Hawaii, the United Kingdom and other countries. They belong to the same taxonomic family as kangaroos and sometimes the same genus, but kangaroos are specifically categorised into the four largest species of the family. The term "wallaby" is an informal designation generally used for any macropod that is smaller than a kangaroo or a wallaroo that has not been designated otherwise.

The Hawaiian crow or ʻalalā is a species of bird in the crow family, Corvidae, that is currently extinct in the wild, though reintroduction programs are underway. It is about the size of the carrion crow at 48–50 cm (19–20 in) in length, but with more rounded wings and a much thicker bill. It has soft, brownish-black plumage and long, bristly throat feathers; the feet, legs, and bill are black. Today, the Hawaiian crow is considered the most endangered of the family Corvidae. They are recorded to have lived up to 18 years in the wild, and 28 years in captivity. Some Native Hawaiians consider the Hawaiian crow an ʻaumakua.

It is a small wallaby found in three isolated areas in Queensland, Australia, and whose population is declining. In early 2019 the total population of the species was estimated to be fewer than 500 mature individuals in the wild and 2285 in captivity.

Monk seals are earless seals of the tribe Monachini. They are the only earless seals found in tropical climates. The two genera of monk seals, Monachus and Neomonachus, comprise three species: the Mediterranean monk seal, Monachus monachus; the Hawaiian monk seal, Neomonachus schauinslandi; and the Caribbean monk seal, Neomonachus tropicalis, which became extinct in the 20th century. The two surviving species are now rare and in imminent danger of extinction. All three monk seal species were classified in genus Monachus until 2014, when the Caribbean and Hawaiian species were placed into a new genus, Neomonachus.

James Campbell National Wildlife Refuge is a National Wildlife Refuge on the island of Oʻahu, Hawaii. It was established in 1976 to permanently protect an ecologically-intact unit and to provide habitat for native and migratory fauna and native flora. It established critical habitat for Hawaii's four endangered waterbirds, the ʻalae kea, koloa maoli, ʻalae ʻula, and āeʻo and many migratory seabirds, endangered and native plant species, and the endangered Hawaiian monk seal and green sea turtle. It also provides increased wildlife-dependent public uses and flood control within the refuge and the local community.

<span class="mw-page-title-main">Cat predation on wildlife</span> Interspecies animal behavior

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 phenomenon, such as in the case of barn cats and other cats kept for the intended purpose of pest control; 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. As an invasive species and predator, they do considerable ecological damage.
