As land development continues to reduce wild areas, wildlife is forced into closer proximity with human communities like Cedarburg. Large mammals, including white-tailed deer, coyotes, and red foxes can be seen within the city limits. There have been infrequent sightings of black bears in Ozaukee County communities, including a 2005 report of a bear in a Cedarburg city park. Many birds, including great blue herons and wild turkeys are found in and around the City of Cedarburg. The Wisconsin Bird Conservation Initiative considers the Cedarburg Bog, located north of the city in the Town of Saukville, to be a Wisconsin Important Bird Area. The rare Goldenseal plant grows in a woodland on the northern boundary between the city and the Town of Cedarburg.
