40/40. The Californian Condor was brought back from the brink of extinction in the US by hand rearing condor chicks in captivity, releasing them back in the wild and guarding their subsequent nest sites around the clock. Today, Californian Condors live and breed in the wild. But not many. By anyone's standards, the investment of people-hours, know how, planning and protection in one wild species was large. Why was the Californian Condor such an important species? And were there wider benefits from the conservation investment than the survival of one large bird species?
If we accept that saving all endangered species might not be practical, affordable or possible - then how are decisions made about what to save? What questions have to be asked and how do conservationists reconcile the balance of winners and losers in any decision made?
We have a special report from Howard Stableford who went to see the Californian Condor project and we'll have James Leape, International Director General WWF live into the programme.
David Robinson, Professor of Biology at the Open University will be in the studio looking at the performance of iSpot across 40 episodes of Saving Species.
And our news hound Kelvin Boot will be in the studio too. The proposed sale of British woodlands no doubt high on his list of weekly stories.
