In addition, the tree is susceptible to certain pests and diseases, such as powdery mildew and canker, which can weaken and damage the tree if left untreated. Climate change is also a concern for Caucasian Zelkova, as shifting weather patterns and extreme temperatures can impact its growth and survival. Conservation efforts and proper care are essential to ensure the continued health and longevity of this valuable tree species.
