Nature & Science

Welcome to the Nature and Science section of the John Muir National Historic Site website. There is a large variety of plants, animals and insects that inhabit this park, including the many acres of Mount Wanda. We work hard to protect and preserve this land and it's inhabitants. There are many native and some non-native species that thrive here. We have provided lists of all the animals, plants and insects that we are aware of. From time to time, we are looking for volunteers to help with maintaining the plants and land around the John Muir NHS and Mount Wanda. If you are interested in volunteering, please contact the park.
