A naturalist guide is a person who has expert knowledge about nature and wildlife. They often work as tour guides, leading groups through parks or other natural areas to help visitors learn about the plants, animals, and ecosystems they are observing. Naturalist guides may also provide educational programs or interpretive services at museums, zoos, or other venues where people can interact with nature in a controlled setting. Their goal is to foster an appreciation for the natural world and help others develop a deeper understanding of the environment around them.
