Koa trees are native to the Hawaiian Islands and are known for their beautiful, dark wood and unique, curved branches. They can grow up to 100 feet tall and thrive in diverse environments, from coastal areas to higher elevations. Koa trees are important to the local ecosystem, providing habitat for various wildlife and contributing to soil health. The wood of the Koa tree is highly valued for its strength and rich color, making it popular for furniture and musical instruments. Due to overharvesting and habitat loss, Koa trees are now considered a vulnerable species, prompting conservation efforts to protect their populations in Hawaii.
