The image of a keeper leading a pony off a heather-clad hill, a deer carcass slung across its back, may sound like something from a Landseer painting, but in 21st century Scotland, Highland ponies - or garrons - are still a valued part of the deer stalking business.

Helen Mark visits the Reay Forest estate in Sutherland to find out what ponies can offer which even the toughest off-road vehicle cannot. Garrons were a fixture of most estates until the 1970s, when in many places they were deemed to be part of the past. Some estates, though, kept garrons for use in the most inaccessible corners of their land, and they are now being adopted for the first time by some estates which have come to see the value of these hardy creatures. Helen hears how the garron is part of the Highland landscape not just for sentimental reasons, creating continuity with the past, but for sound economic and practical purposes too.
