The Koa tree (Acacia koa) is a native tree species found primarily in the Hawaiian Islands. It is known for its beautiful, dark wood, which is highly valued for furniture and musical instruments. Koa trees can grow up to 100 feet tall and thrive in diverse environments, from coastal areas to mountainous regions. Koa trees play a crucial role in their ecosystem by providing habitat and food for various wildlife, including birds and insects. They are also important for soil conservation, as their deep roots help prevent erosion. Conservation efforts are in place to protect these trees from overharvesting and habitat loss.
