Native Hawaiian plants are species that naturally grow in the Hawaiian Islands without human introduction. These plants have adapted to the unique climate and geography of the islands, resulting in a diverse range of flora. Some well-known native plants include the Koa tree, Ohia lehua, and Hapu'u ferns, which play essential roles in the local ecosystem. Many native Hawaiian plants are culturally significant and have been used by the Native Hawaiian people for centuries. They provide food, medicine, and materials for traditional crafts. Conservation efforts are crucial to protect these plants, as many are threatened by invasive species and habitat loss.
