New measures are being introduced to control Scotland's booming trade in wild foods.

Millions of pounds worth of food and foliage are being stripped from the country's forests every year - but most of the people who own the land aren't profiting.

A growing band of commercial foragers are entering woodlands - often without permission - and then selling on the plants, flowers and fungi they collect.

"People are going in to forests all over Scotland and collecting Sphagnum moss for hanging baskets. At Christmas time, they decimate hollies for their berries for wreaths. They're carrying out mushroom collections for hotels and restaurants," explained Mike Strachan of the Forestry Commission.

"It's estimated there's a commercial trade value of £7million to £20million per year, but the landowners are not benefiting from it at all."

New access laws have given the public more freedom to roam the great outdoors.

The Forestry Commission say that it is not a right to profit from nature.

They have launched a new policy to help manage commercial foraging.

"We're not talking about every dog walker having to pay a licence to collect things," said Mr Strachan.

"We're looking at foragers being more responsible and to try and make sure that anybody doing it on a commercial basis has got permission of the landowner to do the work."
