1927 Map of the Arboretum


Did you know that more than a dozen mammal species either live in the Arboretum or have been spotted here?

Many of these animals are secretive, so you may need to be quiet (and lucky!) to catch a glimpse of them. Also, many mammals are either nocturnal (active at night) or crepuscular (active at dawn and dusk), so plan an early morning visit for the best chance of a sighting.
