Mark co-presented the six-part BBC2 television series Last Chance to See, with Stephen Fry, which was broadcast in autumn 2009. The series followed in the footsteps of a similar journey Mark made with the late Douglas Adams 20 years before. It followed the unlikely duo on six separate journeys that took them from the steamyjungles of the Amazon to the ice-covered mountaintops of New Zealand and from the edge of a war zone in Central Africa to a sub-tropical paradise in the North Pacific. Along the way, they searched for some of the weirdest, most remarkable and most troubled creatures on earth. A DVD set of the series is currently available.

At the moment, Mark is co-presenting The Museum of Life, a BBC2 television series that explores the pioneering and often surprising research work and wildlife collections of the Natural History Museum, in London. The Museum has granted BBC cameras unprecedented access for the series, which is being filmed behind the scenes, as well as at locations all over the UK and around the world. It is due to be broadcast in March.

A one-hour Last Chance to See Special Report, called Rhino Rescue and presented by Mark and Stephen Fry, is currently being filmed. They were in the Czech Republic and Kenya before Christmas, and there is more filming coming up.

Mark also presented the weekly half-hour radio programme Nature, on BBC Radio 4, for many years. And he has presented many mini-series and one-off programmes for BBC Radio 4, including Dreaming of Whales, Tough Lives and Superlative Birds. He provided the daily Environment News bulletin for Steve Wright in the Afternoon on BBC Radio 1 and is a frequent contributor to many other radio and television programmes about wildlife and conservation.
