The the biodiversity crisis and the destruction of the environment they are patents made today and is manifested in the loss and decrease of species all over the planet.

Its decline and deterioration of their State of conservation are evident in all animal groups.

The 23% of mammal species they are threatened to a greater or lesser degree

Captive breeding program

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.

The EEZA currently participates in projects of conservation of North African Gazelles through programs of reintroduction and reinforcement of Gazelle Gazelle and dorcas Lady in Senegal

Gazella cuvieri

It is a Gazelle of medium size, which can reach 35 kg. weight. Until the mid-twentieth century its name from mountain Gazelle or Gazelle from the Atlas was a vast mountainous territory of Morocco, Algeria and Tunisia and from there.

Hunting pressure and the progressive deterioration and loss of their natural habitat are the main causes of its decline. Currently it is only in small isolated enclaves, where it is estimated that there is a global population of less than 800 individuals. It is regarded by the International Union for the conservation of nature (IUCN) as in "Danger of extinction".

The current population, about a hundred individuals, comes from three specimens (1 male & 2 females) brought from Western Sahara in May 1975 and a female imported from Morocco which was brought to a private estate of Almería and his blood went on to join the genetic stock of the population of the Park in 1987.

Gazella dama

[ {T} ]

The dama Gazelle is the largest of the three species of Gazelles that are held in La Hoya. Males are larger than females, reaching 65-70 kg. weight. Individuals belong to the subspecies mhorr. This subspecies is extinct in most of its natural territories and is currently on the verge of extinction in the wild. Its natural distribution area stretched by the Western Sahara from Morocco South to Senegal. The main cause of their decline has been hunting pressure which has been subjected for many years and this, together with the degradation and fragmentation of their habitat, has led to the IUCN to consider it as a species in danger of extinction and to be included as a species I in the CITES Convention.

The captive population comes from four exemplary founders (1 male and 4 females) brought in 1971 and 1975 of the Sahrawi Arab Democratic Republic. The captive population currently exceeds 175 individuals, of which 90 are in La Hoya and the rest in different zoos in Europe, United States and Canada.

Responsible for the maintenance of the studbook of the species, are Gerardo Espeso and Andrés Barbosa.

Gazella dorcas

It is of small size and their weight ranges 15 to 18 Kg. Their natural habitat covers a vast territory of North Africa, from the Atlantic to the shores of the Red Sea, and from the Sahel to the shores of the Mediterranean Strip. Currently, there are five subspecies described throughout its area of distribution.

Its decline is due more to hunting pressure that the loss or deterioration of their habitat. It is currently rated as a "Vulnerable" species by the IUCN.

The population of La Hoya belongs to subspecies neglectaof the western edge of the Sahara desert, where 14 individuals were brought in the first. The captive population that remains in the installation ranges environment 85 copies, which are joined by residents in different zoos in Madrid, Barcelona, Jerez de la Frontera, theme park of the Tabernas desert, Nueva de Llanes, Marwell Zoological Park (United Kingdom) and Zoo of Hannover (Germany).

The responsible for the maintenance of the studbook of the species, as well as the coordination of the EEP is Teresa Abáigar.

Ammotragus lervia sahariensis

In the Experimental Farm of "La Hoya" is also a captive population of a North African goats, the Saharan Barbary sheep, subspecies of mountain areas at the western end of the Sahara desert. The taxonomic status of this species is subject to review and their natural populations are now extinct. This is due, primarily, to heavy hunting pressure to which have been subjected their populations. The captive population has its origins in three individuals (2 males and 1 female) brought in Western Sahara since 1975 and today there are about 50 individuals.

Responsible for the maintenance of the studbook of the species is Gerardo Espeso.
