Given the failure of several ferret reintroduction attempts in the region over this period of time, we also evaluated current attitudes and perceptions regarding endangered species management in general, including when to abandon recovery efforts.
On the farm, Isa and Fera were the first guests of the first center for the reintroduction of big felines in Brazil, measuring 1 hectare (2.5 acres), or the size of a soccer field. Despite two failed attempts, in 1959 and 1968, sea eagles from Norway were successfully re-established on the west coast of Scotland in 1975 and 1985.They bred in 1983 for the first time in more than 70 years.

Findings from the projects will help inform future decisions on the potential reintroduction of the species into a wider area. The reintroduction of a species into a release site will fail if the habitat cannot provide the correct support for the species, irrespective of the strategies put forward to initiate the growth a new population (Armstrong, 2008). Species reintroduction is about more than animals, with rare and specialised wetlands plants being an essential part of these precious ecosystems.
If this were to occur, however, this would be resource-intensive and potentially delay any decision on species reintroduction indefinitely.
Bald eagles. Given large carnivores are declining globally [14], identi-fying the successes and failures of reintroduction attempts is
Species reintroduction is about more than animals, with rare and specialised wetlands plants being an essential part of these precious ecosystems. We are working to reintroduce classic peatland species such as common and hares-tail cotton grass, cross-leaved heath and sphagnum mosses.
The reasons for the species decline are believed to be mainly anthropogenic, acting over a period of several decades.
It now has a high degree of legal protection, but it was not ... for success/failure:
Using radio-telemetry and mortality sensors, survivorship of the reintroduced oribi was monitored, and the factors involved in a success- ful or failed reintroduction attempt identified.
So too are other still-listed species. The success of species reintroductions can depend on a combination of environmental, demo-graphic, and genetic factors.
This volume presents a comprehensive review of reintroduction projects and practices, the circumstances of their successes or failures, the lessons learned, and the potential role for reintroductions in preserving species threatened by climate change.

Pleistocene rewilding entails reintroducing species or descendants of megafauna species from the Pleistocene era, more commonly known as the Ice Age.
Species Reintroduction ProgramsIntroductionThe reintroduction of species to the wild is the latest step in the effort to preserve animals, birds, insects, and plants that are endangered or extinct in the wild. In: Wich SA, Utami Atmoko SS, …
Several species are now making serious comebacks in Europe, thanks to persistent efforts by conservationists towards reintroducing species, increasing their protection, and creating corridors to enable their movement. Bald eagles once nested on each of …
reintroduction as a conservation measure, its history and broad reasons for successes and failures.
These approaches can have high costs in terms of money and mortality of precious rare animals, hence lessons learned from ongoing efforts are important to convey. Since rare species are generally incapable of surviving in their current, altered natural environ-ments, many conservation programs are required to preserve them
Given large carnivores are declining globally [14], identi-fying the successes and failures of reintroduction attempts is
Now, thanks to multiple different reintroduction sites, there are close to 1,000 individual 2014). No strict and accepted definition of reintroduction success exists, but it has been proposed that the criteria widely used to assess the conservation status of endangered taxa, such as the IUCN Red Listcriteria, should be used to assess reintroduction success.
Often it is considered the only remaining option for ecological restoration in many regions, particularly industrialized countries, in which the native fauna has been decimated and natural recolonizations are unlikely to occur. In both cases, wild individuals are captured in one location and translocated directly to another.
Reintroduction of wildlife is aimed at accomplishing 2 broad objectives, one being reestablishing species into the wild when the original species is extinct in that region, an example of this is the reintroduction of Cheetahs in India and the second objective is to supplement a species if they are in decline in a particular habitat.
... Feral cats have become an increasingly common invasive species as humans have introduced domestic cats into new ecosystems.

Orangutan rehabilitation and reintroduction: Successes, failures, and role in conservation. Causes of reintroduction failure of the brown treecreeper: Implications for ecosystem restoration.
It is a peculiar notion of failure, given that all three are at their highest levels in more than half a century.
Large predators are among the most threatened species on the planet and ways of conserving them in the face of increasing human populations and associated resource requirements are becoming critical.
Global biodiversity loss is a well-documented phenomenon that threatens ecosystems worldwide.
Reintroducing species in new natural habitats is a strategy to help prevent the extinction of the most threatened organisms.
The brown treecreeper (Climacteris picumnus) reintroduction into two nature reserves in the Australian Capital Territory in south‐eastern Australia failed to meet its predetermined criteria for success.This occurred despite prior … cent rate of failure,” because none of these species has yet been removed from the endangered list.
Gauging Success or Failure The International Union for Conservation of Nature (IUCN) guidelines on the reintroduction of a species state that the anticipated impact of such programs has to be considered, including the impact on humans before initiating such schemes. The reintroduction of species is increasingly seen as an important conservation tool that helps in the restoration of an ecosystem (Wilson, 2004; Manning et al., 2009). survivorship of the reintroduced oribi was monitored, and the factors involved in a success ful or failed reintroduction attempt identified.
Yet, there have been enough success stories, for …
E arlier this month, an environmental organization announced it had released 26 Tasmanian devils ( Sarcophilus harrisii) into a sanctuary north of Sydney as part of a project to reintroduce the species to the Australian mainland, where it has not existed in the wild for about 3,000 years.
The former is termed reintroduction and the latter reinforcement.

Concern over high failure rates prompted analyses of the factors associated with translocation success.
Just a few months ago, a last-minute deal during federal budget negotiations stripped federal endangered species protection for wolves, leaving wolf management to the states of Idaho and Montana.
However, few studies have reported the outcome of reintroduction efforts in plant species. Critics point to the need to conserve/restore habitat, list examples of failures, decry the cost, and argue we should rescue species before they are on the brink of oblivion.
In the context of species conservation, reintroduction is the only logical step that rehabilitation centers should be making.
One way to approach this issue is to look at the current population numbers based on the population before reintroduction.
Channel Islands National Park, California.
IUCN’s Reintroduction Specialist Group Global Perspectives in Reintroduction Biology, to identify the objectives set by reintroduction practitioners, the indica-tors of success they choose and the types of difficulties they encounter.
The ultimate objective of any reintroduction is the establishment of a self-sustaining population and, using this definition, reviews of reintroduction outcomes have indicated generally low success rates , as low as 23% .
The objective of the project was to use the animals to restore the wet grassland habitat of national importance. This is the first reintroduction of an endangered species back into Missouri. Reintroduction of native species has become increasingly important in conservation worldwide for recovery of rare species and restoration purposes. Reintroduction in Missouri .
The number of species and the diversity of taxa reintroduced, and the number of reintroduction projects have increased substantially in recent years (Seddon et … Reintroduction of large carnivores might not affect the ecosystem much at all. At the time of reintroduction planning, the species was listed as a national biodiversity priority and remains so. This approach offers promise for rapidly extracting explicit and latent information from a large corpus of scientific texts. Reintroduction biology is new and continues to be a work in progress.
