YOURS TO EXPLORE. YOURS TO PROTECT.

Along with the beautiful views of Grass River, we also offer seven miles of well-maintained trails including 1.5 miles of boardwalk floating above northern fen and cedar wetlands. With all of these natural features, Grass River Natural Area offers visitors an outdoor, living laboratory to explore and learn.

WHAT DOES THE RIVER OTTER TELL US?
River otters are an amphibious mammal that are known for their curious nature, intelligence, and playfulness. Did you know they can act as environmental indicators (also called indicator species)? Contaminants that occur in the environment can concentrate in the otter over time in a process known as biomagnification. For this reason, river otters do not tolerate polluted waters and are typically found utilizing only high quality rivers and wetlands. Therefore the presence or absence of river otters in an ecosystem can serve as an indicator of habitat quality. The video below recorded a river otter family using the protected streams at Grass River - a sign of the health of the natural area and of your efforts to protect it!
