Rare plants are species that have a limited distribution and are often threatened by habitat loss, climate change, or invasive species. These plants may be found in specific regions or ecosystems, making them vulnerable to extinction. Conservation efforts are crucial to protect these unique species and their habitats. Some examples of rare plants include the Franklinia alatamaha, which is extinct in the wild, and the Rafflesia arnoldii, known for its large flowers. Many rare plants are also important for biodiversity, as they can provide essential resources for wildlife and contribute to the overall health of their ecosystems.
