A wild field or wilderness reserve is a place where lots of animals and plants get to live freely without being disturbed by people. It is a place where the environment is left alone so that animals can have plenty of space to live, grow, and raise their babies. It's like a safe and cozy home where they can live without worrying about being hurt by people. People can visit these places to enjoy the beautiful natural scenery, but we have to be very careful not to disturb the animals or their homes. It's important to keep the wildness in these places so that they can continue to be home for many kinds of animals and plants.
