I want to know the answer to the following question:
The somerset level is the only area left  to commercially grow what
All the background I'm provided with is that "Traditional willow growing and weaving (such as basket weaving) is not as extensive as it used to be but is still carried out on the Somerset Levels and is commemorated at the Willows and Wetlands Visitor Centre.". Is that enough to answer the question?
Answer: no
