Diego belongs to the species Geochelone Hoodensis, the English island, part of the Galapagos archipelago. In 1977, the turtle returned to the Galapagos Islands from San Diego Zoo, California, hence its name.
Upon arrival, Diego became part of a group of two male and 12 female turtles, which, being the only survivors of their species, were taken to the Galapagos National Park (GNP), on the island Santa Cruz.
Until then arrived to take part in a breeding program, according to the PNG technical, so far has reported the birth of more than 1,700 babies and their subsequent reintegration into the English island.
Ecuadorian and U.S. researchers have followed this process, in which reproductive capacity Diego has become evident.
"Diego has been very active and has been one of the pillars for the reproduction of their species," he told BBC World Sixto Naranjo, head of the Preservation and Restoration of Ecosystems Island PNG.
Back to the natural environment
Diego will be reintroduced to the natural environment of the English island later this year, according to Sixto Naranjo, who emphasized that the turtle remains beyond reproductive potential that their age exceeds 130 years.
Reintegrating Diego and the other turtles of the species that have been kept in captivity will contribute to the development of new offspring in the wild, with a broader genetic diversity, which has been a topic of interest to several researchers.
"It is important that the descendants have as many different fathers as possible. So the fact that Diego is conducting most of the reproduction is not necessarily a good thing as it reduces the genetic diversity of future generations , and thus its potential to evolve and respond to environmental changes, "he told BBC Gisella Caccone, a professor at American University of Yale.
However, Caccone believes the breeding program Hoodensis Geochelone tortoises as a successful experience can be replicated in other species giant tortoises.
"We're helping PNG to establish additional breeding programs for other species of Galapagos giant tortoises that are in extreme danger of extinction," he said.
Lonesome George, the end of the spectrum
While preparing Diego reintegration of the natural environment, technicians PNG and Yale University hold out hope that the "Lonesome George" and the two new colleagues who were placed in his back yard to achieve reproductive weeks ago during the mating season between May and October next.
say A Yale researcher, the case of "Lonesome George" is on the opposite end of the spectrum in terms of reproductive success.
"As in any species, there is variation in reproductive success. And Diego and Lonesome George are at opposite ends of the spectrum," he said Gisella Caccone.

A giant tortoise of the Galapagos Islands known as "Super Diego" has developed a reproductive capacity of a standard that has helped to save their species from imminent extinction. 
Diego's story contrasts with that of the famous "Lonesome George", one of a giant tortoise species, which has failed to have children despite many efforts by researchers.
