Like all plants and animals, the Doré de Lyon chestnut tree has some threats that can hurt it. Bugs or tree diseases can damage the leaves or chestnuts and make the tree weak. Weather can also be harmful to the tree. Too much rain can hurt the roots, and strong winds or storms can break the branches. Even though these things can happen, the Doré de Lyon is strong and healthy. People take care of them so they are not in danger.
