Species reintroduction is the process of bringing a species back to its natural habitat after it has been extirpated or is at risk of extinction in that area. This can involve breeding individuals in captivity and then releasing them into the wild, aiming to restore ecological balance and biodiversity. Successful reintroduction efforts often require careful planning, including habitat assessment and monitoring of the released species. Examples of species reintroduction include the gray wolf in Yellowstone National Park and the California condor in California. These efforts can help revive ecosystems and promote conservation awareness.
