The Lehua tree, native to Hawaii, is susceptible to several diseases that can affect its health and growth. One common issue is Rapid Ohia Death, caused by a fungal pathogen that leads to tree decline and death. This disease poses a significant threat to Ohia forests, which are vital to Hawaii's ecosystem. Another concern is Corynespora leaf spot, a fungal infection that causes leaf discoloration and premature leaf drop. This can weaken the tree and reduce its ability to photosynthesize effectively. Proper management and monitoring are essential to protect Lehua trees from these diseases and ensure their survival in the wild.
