The Percheron horses can shift eight to ten tonnes of timber - the equivalent to the weight of a double-decker bus - in just one day
Locals are using the traditional horse logging techniques to reduce the high level of untreated woodland in the national park.
They are being trained to manage the Percheron horses to clear timber from wooded sites, which make up more than 40 per cent of the park.
The people have been shown how to load logs and woodland on to wheeled carts, which are connected to a harness and attached to the horse.
If the woodland is left alone, the quality of the habitat will decline, pests and disease could spread and this could result in fewer wildlife species living in the area.
The horses - which can tow eight to ten tonnes a day - are used in areas that cannot be reached by modern machinery.
As well as being able to access the areas, horses also have the advantage of not causing damage to the ground.
In addition, footpaths do not have to be closed around the areas, and there is less noise pollution.
