Gardner defines Naturalistic Intelligence as the ability to recognize, categorize, and draw upon certain features of the environment. It's one of the intelligences in his Theory of Multiple Intelligences. This type of intelligence is not just about knowledge of nature, but also involves a deep understanding of living things and being attuned to natural phenomena. People with high naturalistic intelligence are skilled at identifying and classifying various aspects of the natural world, like animals, plants, weather patterns, and geographic formations.
