Nature Society

The Royal Oak Nature Society is a volunteer group working with the City to protect and promote the usage of Royal Oak's two nature preserves, Cummingston Park and Tenhave Woods. We are also in the process of developing an arboretum and wildflower garden behind the Royal Oak Senior Center (3500 Marais).

Both Cummingston Park and Tenhave Woods are nature areas that are over 20 acres in size and are heavily wooded with lined trails. They are open daily to the public from dawn to dusk. Dogs are not allowed inside either nature area. To learn more about why dogs are not allowed in these parks, please review Why Dogs Are Not Allowed In Our Nature Parks (PDF). Wearing boots while in the parks is recommended during the winter and spring months. Using insect repellent and dressing appropriately is advised from late spring through the end of summer.

To learn more about these parks firsthand, please come to our naturalist led nature walks. To find out when and where they are scheduled, visit our Nature Walks Page. Our Park Locations Page has links to trail maps of the two nature parks.

ROOTS Foundation


The Nature Society is a member of the Royal Oak Opportunity To Serve (ROOTS) Foundation, established by the city to accept donations and endowments for the improvement of civic institutions. Donations and bequests may be designated for specific Nature Society projects. For more information, visit the ROOTS Foundation Page.

Tree Species


One of the long term goals of the Nature Society has always been to have as many different native  Michigan tree species as we can in our three parks (Cummingston Park, Tenhave Woods and the Royal Oak Arboretum).  Please view this Table (PDF) that lists Michigan’s native trees and their status in these three parks. We will periodically update the table as we plant or find more tree species.

Land History


Behind the natural beauty of Tenhave Woods and Cummingston Park, there is a land history to explore. Please check out these links to Tenhave Woods (PDF) and Cummingston Park (PDF) to learn about the people who once lived on these lands.

The Goodwin family was the first owner of the land that now includes Tenhave Woods. The photo on the right is of Samuel Volney Goodwin's family and farmhouse during the middle 1880s. Samuel is the third generation of Goodwins to own this piece of land.
