Nature Society

WHO ARE WE: The Royal Oak Nature Society is a volunteer group working with the City of Royal Oak to protect, maintain 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 (Royal Oak Arboretum) behind the Royal Oak Senior Center (3500 Marais).  Go to the Nature Society page to learn more about us. 

ABOUT OUR PARKS: Both Cummingston Park and Tenhave Woods are nature preserves that are over 20 acres in size and are heavily wooded with lined trails.  They are designated by the city of Royal Oak as conservancy parks where the protection and management of the animal and plant/tree life in the parks is the primary concern.  They are open daily to the public from dawn to dusk.  Click here to find out why dogs are not allowed inside either nature preserve.  Go to Nature Preserves page to learn more about Cummingston Park and Tenhave Woods. 

The Royal Oak Arboretum is a park located behind the Senior Center.  It has been under development since 2007.  The long range plan for our arboretum is to create a collection of native trees/plants that are not found in Tenhave Woods.  Link on to Royal Oak Arboretum to learn about its history and progress. 

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, go to Naturalist Lead Walks.  Our Park Locations page also includes links to trail maps of these parks.  If you would like to help the Nature Society with the maintenance and improvement of these two nature areas and the arboretum, please check out our Volunteer Opportunities page.


June Program


It will be held on Wednesday, June 7th, 2017 at the Royal Oak Arboretum beginning at 7:30 pm
 We will talk a little bit about what is going on in the arboretum and future plans there.  Afterwards, there will be an arboretum walk.  Meet at the Royal Oak Senior/Community Center (3500 Marais) parking lot-north end.


Friends of Fungi Mycology Club 

This group promotes the understanding of, and an appreciation for, fungi in general and those fungi found in Tenhave Woods, Cummingston Park, and other local urban woods. The group is open to anyone who wants to learn more about fungi which includes mushrooms. Check out this

Native Tree Collection

One of the long term goals of the Nature Society has always been to have as many of Michigan's 86 tree species as we can.  We have 41 native species in Tenhave Woods, but because it is a nature area, we can’t plant any new species there. Presently, we have 24 native species that can be found in our arboretum (located behind the Senior Center) that can't be found in Tenhave.   There are 5 other species growing in our nursery.  That leaves 16 species of native Michigan trees that we need to obtain and plant in our arboretum in order to reach 86.  Check our table of Michigan’s native tree species to see where we stand with each of them.  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 above photo 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.

Special Thanks


We'd like to offer a special thanks to the ROAK Brewing Company for their very Generous Donation (PDF).


The Nature Society wants to thank Brendan Nolan’s “Plants for Ecology” for donating several Black Willows, a Tamarack and an Elderberry tree.  If you are looking for native plants, you might want to check him out at Royal Oak’s Farmer Market sometime.  More information can be found at his “Plants for Ecology” website.
