Some stunning photos from last week. This one was my favourite.
A herd of European bisons graze in the Rothaargebirge mountain range near Bad Berleburg, Germany. The herd was released in the wild to restock bison population as part of the Wisent Welt Wittgenstein project, a government-funded initiative. European bison were once plentiful across Europe and Russia, but their numbers have dwindled drastically because of hunting and habitat encroachment. Photograph: Thomas Lohnes/Getty Images
