Forest at risk from bloom in tourism

HALLE, Belgium - A carpet of bluebells bursts into flower in Belgium in a wonder of the natural world - but one that is at risk of being trampled by tourists drawn to its beauty.

For two or three weeks in April, the ground of the Hallerbos wood just outside the capital of Brussels is transformed into a breathtaking sea of shimmering purple.

"The scene is like in a fairytale, we're still expecting a little elf or witch to appear from nowhere," says Marie-Rose, who is walking through with her husband.
