Numerous animal species are currently threatened or endangered species in the world.
In the majority of cases the human activity (overhunting, habitat destruction or fragmentation) is the cause of such situation.
In the case of the Gazelles that are held in La Hoya decline that they have experienced their natural populations in the wild has mainly due to the pressure game, transformation and progressive deterioration of their natural habitat, and competition that have suffered with domestic cattle.
This situation of biodiversity loss tools allowing to restore wild populations of some of these species are needed.
A tool for conservation
The bred in captivity represents a useful tool for the conservation of endangered species. Although it would be desirable to avoid having to resort to it, sometimes it is the only (last) alternative to avoid the full extinction of these species.
Ex-situ conservation projects represent since they are held mostly in places and countries where there was no species object of the breeding programme.
It is a program using which is aims to reach a size of population enough large enough to allow, through reintroduction or reinforcement, projects the restoration of the species in one or more of the areas in which their populations were historically distributed.
For this purpose it has with the collaboration of numerous Zoological nucleiwhich disperse small groups of individuals in the breeding programme. This allows for greater availability of space, and therefore be able to increase the size of the captive population, but, above all, avoid that in case of disease or epidemic the captive population is affected.
Different strategies to curb the decline of animal populations and the extinction of species have to solve numerous problems, both ecological (establishment, retention and dispersal of populations reintroduced, its impact on natural ecosystems...) as socio-economic (interaction of the species in question with the activities human, its use as a natural resource).
Since its inception the research has been fundamental both for species subject to these programmes, to develop and implement strategies to improve their survival and well-being in captivity. Some projects have been aimed to determine the status of the species in freedom. Finally the reintroduction is the ultimate goal of this program and these years have been conducted reintroductions in Senegal, Morocco and Tunisia.
