Heart-warming: Mikkel Legarth giving the lioness Sirga a hug in the wilds of Botswana
Sirga treats the two conservationists just like she would other lions and with their help she can now hunt for prey on her own.
She is now a beacon for hoped success of the Modisa Wildlife Project, founded in Botswana, Africa, by Mr Gruener, from Germany, and Mr Legarth, who is Danish, with the hope of saving the lion population.
Botswana is two and a half times the size of Britain and has vast areas of wilderness - but already increased farming is bringing lions and man into more and more conflict.
From a base camp in the African bush the Modisa Wildlife Project has been working with local farmers and Willie De Graaff, owner of Grassland Safari Lodge, to find a way long term solution.
The plan is to relocate the lions which are coming into contact with farmers to one large protected area where they have enough wild prey to feed on.
As these amazing shots show Mikkel and Valentin has an incredible affinity for the lions they rescue and not just Sirga.
