You can still see a lot of mulberry trees in the Cevennes. Silk worm breeding started in the Cévennes in the 16th century. The larvae were fed the leaves of the mulberry tree. No less than one ton of leaves was needed to feed 25 g of worms for one month. That's why you will see a lot of mulberry trees in the villages. The currrent production is almost nihil. The silk activity had a lasting effect on the architecture in the region. Buildings were transformed and extra floors were added to make room for the silk worm production.
