Sweet Chestnut trees face several threats, both natural and man-made. One of the biggest threats to the species is the chestnut blight, a fungal disease that has devastated populations of chestnut trees in Europe and North America.

Additionally, deforestation and habitat loss pose a threat to the species, as their natural habitats are cleared for agriculture and development. Conservation efforts are underway to protect and preserve Sweet Chestnut trees for future generations.
