Despite recent efforts to develop the science of reintroduction biology, there is still no general and broadly accepted definition of reintroduction success. We investigate this issue based on the postulates (1) that successful reintroduction programs should produce viable populations and (2) that reliable assessments of ultimate success require that populations have reached their regulation phase. We assessed if the viability of these reintroduced populations could be evaluated using the same… 

Developing a standard for evaluating reintroduction success using IUCN Red List indices

The need for and practice of reintroducing species as a conservation mitigation strategy has been on the rise for over two decades (Seddon, Armstrong & Maloney, 2007). The goals of conservation

Using the IUCN Red List criteria to assess reintroduction success

In 2014, there were over 250 papers published in the peerreviewed scientific literature (Scopus query) documenting some aspect of reintroduction biology – the study of the biological, social and

Distinguishing reintroduction from recolonization with genetic testing

Reintroduction efficiency: a stepping stone approach to reintroduction success?

The need for intensive restoration actions will likely increase in years to come in order to cope with the local extirpation of wild populations worldwide (Ceballos, Ehrlich & Dirzo, 2017).

Alternative perspectives on reintroduction success

Reintroductions of both animal and plant species have been occurring for decades; however, many of these reintroductions have met with failure (Deredec & Courchamp, 2007). Yet, there have been enough

On the sustainability of a reintroduced Crested Ibis population in Qinling Mountains, Shaanxi, Central China

The reintroduction of the Crested Ibis in Qinling Mountains has great promise, and progress toward a self-sustaining population has been made under some interventions, but governments, local communities, and scientists need to facilitate habitat restoration for the long-term survival of this endangered species.

Characterizing recolonization by a reintroduced bear population using genetic spatial capture–recapture

The utility of noninvasive genetic sampling in conjunction with spatially explicit capture–recapture models to characterize and monitor recolonizing bear populations is demonstrated, which may also be useful for management of expanding populations of other large carnivores.

Reintroducing reintroductions into the conservation arena

We are grateful for the interesting and constructive comments on our article and largely agree with the points raised by the three commenters. If we intend to improve reintroduction biology, the

How to plan reintroductions of long-lived birds

The dynamics of released long-lived bird populations are examined in object-oriented simulated reintroduction programs to show that as more young per year are released the new population is going to be larger at the end of the simulations, the lesser the negative effects in the donor population and the lowest the total budget needed will be.



Directions in reintroduction biology.

Captive breeding genetics and reintroduction success

Modelling the dynamics of introduced populations in the narrow‐endemic Centaurea corymbosa: a demo‐genetic integration

The results provide strong management guidelines for future introductions of C. corymbosa regarding the number of seeds required and the benefits of introducing them into several sites to achieve population persistence and highlights the general importance of integrating demography and genetics to compare the effectiveness of different management strategies.

Ecological requirements of reintroduced species and the implications for release policy: the case of the bearded vulture

It is suggested that population restoration would be more efficient if releases were concentrated within large limestone massifs, as reintroduced bearded vultures tend to be philopatric.

When to end releases in reintroduction programmes: demographic rates and population viability analysis of bearded vultures in the Alps

A stochastic population model is built to estimate population growth rates, and the value of continuing to release birds for varying periods into the future is explored, to optimize decision-making within a major reintroduction programme.

iv Reintroduction is a popular but much debated conservation tool. It is often seen as costly, too species-focused, and risky. Part of these programs concern locally-extinct species that are not

Predictive accuracy of population viability analysis in conservation biology

It is found that PVA predictions were surprisingly accurate, the risk of population decline closely matched observed outcomes, there was no significant bias, and population size projections did not differ significantly from reality.

Roles of survival and dispersal in reintroduction success of Griffon vulture (Gyps fulvus).

It appears that among reintroduction programs difference in failure and success was due to differential dispersal among release sites, and it is shown that mortality can be homogeneous from one program to another while, on the contrary, dispersal is highly dependent on the matrix of established populations.

The value of an adaptive approach to harvesting source populations for reintroduction and the value of such studies for understanding the density-dependent mechanisms regulating populations are illustrated.

Assessing Extinction Threats: Toward a Reevaluation of IUCN Threatened Species Categories

Proposed categories of threat based on the theory of extinction times for single populations and on meaningful time scales for conservation action are presented and suggest are appropriate at least for most large vertebrates.
