For our first Stewardship Talk of 2020 we are excited to host Dr. Pete Blank from The Nature Conservancy for his talk, “The Poweshiek Skipperling Butterfly: The Life and Times of Michigan’s Most Endangered Species.” The talk is free and will be TONIGHT, January 30, 2020 at 6:30 pm at the Paint Creek Cider Mill, 4480 Orion Road, Rochester, MI 48306.
The Poweshiek Skipperling butterfly was once common in the Upper Midwest in tallgrass prairies and prairie wetlands. Over the last 20 years its population has crashed and the species is now endangered in North America and critically imperiled in Michigan. One of its last strongholds is Oakland County, Michigan. Dr. Blank will discuss the current population status of the Poweshiek Skipperling, its life history, and efforts to bring it back from the brink of extinction.

Another trip around the sun. Transitions from bitter winter to resplendent spring, from riotous summer to fall splendor, from year to year. You’ve been here with us, reading our musings and celebrating our natural areas.
Transitions help us consider what’s important and appropriate, both in our personal lives and on our land. Transitions rarely come or go easily, especially if we really liked how things were, or had just done it that way for a long time. Trees grow, turning field to forest. We plant wildflowers where crops once grew. Wetlands rise from fields that were once drained. And through it all we come together, a community of people who care about restoring our connection to nature.
When I reflect on the transitions in my life, the ones I remember joyfully happened in community. We’re thankful for you, our community, and the support you give as we launch big transitions in the natural areas of Oakland Township’s parks. Even though we recognize the noble goal of restoring habitat, change is messy and hard. But since we work together as a community, we reflect on this past year with satisfaction and look forward to the next with joy.
Things are happening at Gallagher Creek Park! This little park in the southwest corner of Oakland Township spans 15-acres at the headwaters of Gallagher Creek, an important water resource in the township which was home to a remnant native brook trout population just a few years ago. Outside the developed area near the parking lot, wetlands at Gallagher Creek Park host a variety of birds and wildlife, and prairie plantings installed between 2016 and 2018 blanket the upland areas.
In 2018 Oakland Township Parks and Recreation added a playground, picnic shelter, and rain garden at Gallagher Creek Park, and expanded the parking lot. All this work wrapped up just as fall set in last year. This spring we added finishing touches with installation of native plant landscaping around the playground. Join me, Ben VanderWeide, for a tour of the first year of our new landscaping!
Native Plants for a Better World
We use native plants throughout our parks because they are important for a healthy environment. Native plants provide food resources and habitat for pollinators, and filter runoff and sediment from storm water flowing from developed areas of the park before it reaches Gallagher Creek. Check out great books by Doug Tallamy if you’re interested in learning more about the benefits of native plants.
The landscaping surrounding the playground and picnic pavilion creates a transition from the play area to the existing natural community in the park, connecting visitors, especially young children and their parents, to nature. We designed this transition landscape to be visually appealing by using low-growing plants, showy flowers, and neat edges. Check out our plant list here. Our native plant landscaping is a free, publicly accessible resource for educators, nature centers, and anyone who wants examples of how to use native plants.
After the playground and other improvements were finished in 2018, we were left with fairly compacted soils. Some areas had fill dirt and one spot had a thin layer of soil over driveway gravel! We didn’t have the time or resources to loosen the soil, so we just hoped the roots of our tough native plants would break through the hardpan. Our site preparation mostly involved removing sticks, large rocks, and any existing plants. The total area of the native planting is about 9,000 square feet.
The area near the parking lot had been accidentally seeded to turf the previous year, so we had to kill the grass first.
A few weeks before we started planting, we celebrated the grand opening of the playground equipment and other improvements. Jane Giblin was there representing both The Wildflower Association of Michigan and Rochester Garden Club, two organizations which provided grants to help us buy plants. Stephanie Patil also generously gave us a donation to help purchase plants. Thanks!
The last thing we did before planting was place the log edging. We used black locust logs left over from another project. Black locust resists rot, making it favorite choice for fence posts by farmers of the past. What a great use of this invasive tree!
All that preparation got us ready for the main event, planting! We put out the call for volunteers, and many of you showed up! The slideshow below shows our process. We first marked out each planting zone, then dug holes using a bulb planting bit on a gas-powered drill. After placing the plants in the holes, we carefully packed dirt around the plugs to eliminate air gaps. We mulched around the plants and gave them a good soaking. Finally, we put small identifications signs throughout the landscaping to help people learn the names of the species we’d planted.
Weeding and Watering Through the Summer
Even with careful site preparation and a few inches of mulch, we prepared ourselves for a big flush of weeds from our post-construction soils. The worst weed problem the first year was annual grasses, but we had to be vigilant as seedlings of cottonwood, Canada thistle, quack grass, and crown vetch emerged.
As summer began, we watered about twice per week to help the plants establish. Ample rain fell during the second half of the summer, so we only watered as needed. The seasonal stewardship staff did great work hauling water to the site in a large tank and keeping the weeds down. Thanks Alex, Marisa, and Grant! I know a few volunteers also stopped by to help with weeding. We couldn’t have done it without you!
Monarch Butterflies Love the Plants!
As plants grew larger, we found monarch caterpillars on the butterfly milkweed, and adults enjoying the nectar of blazing star. Hurray for pollinator habitat!
From Small Plugs to Big Plants
Our little plants didn’t look so small by early September! The sedges and grasses did especially well, providing nice texture and structure. Some forbs (wildflowers) did well and even flowered their first year; others invested their energy in putting down deep roots. We weren’t able to get some species in the spring, so we planted a few additional species in the fall – western sunflower (Helianthusoccidentalis), round-leaved ragwort (Packera obovata), and nodding wild onion (Allium cernuum). Fall plantings don’t need to be watered as much, and the plants get a head start for the next year!
Looking Ahead to Next Year
Next year we won’t have to plant everything again, so we’ll be switching gears to long-term maintenance. In 2019 we mulched the plantings to help retain moisture and suppress weeds, but we’re planning to reduce or eliminate additions of new mulch in the plantings over the next few years. We included several species that spread by rhizomes or stolons as part of our “green mulch” strategy – allowing the good plants to create a dense canopy that resists the establishment of new weeds.
Next year we won’t need to water, unless we have a severe drought. At that point, the plants should have established deep roots, and will be able to handle the normal fluctuations in moisture and temperature for southeast Michigan – another advantage of native plants!
Weeding will continue to be important until we’ve reduced the weed seed bank and established our green mulch. I’ve found that a few years of intensive weeding can reduce the weed pressure to almost nothing. Only a few quick scans will be required every month to catch problems before they become big ones.
Every year we’ll evaluate the species mix in our plantings. What’s doing well? What didn’t grow much? Do we have consistent blooms to support pollinators throughout the growing season? We’ll add species and thin others, fine-tuning our native landscaping.
We’re looking forward to the challenge and joy of watching our native plant landscaping change and grow over time. We hope you’ll join us, whether you’ve been a gardener for decades or are just interested in native plant landscaping. All are welcome!
I want to personally invite you to the Oakland Township Parks, Recreation, and Land Preservation Master Plan Open House on Wednesday, October 23 at the Oakland Township Hall (4393 Collins Road, Rochester, MI 48306). We will have two drop in sessions – the first is from 2-4 pm, and the second is from 6-8 pm. We will have poster-sized maps and concept plans for each park that you can view and mark up. You will also be able to view and comment on new Parks and Recreation logo concepts and draft plans the new trailhead along the Paint Creek Trail at our Paint Creek Junction park (currently an undeveloped parcel north of Adams on Orion Rd). And we’ll have snacks, of course!
We really appreciate your support and input during our planning process. We have a strong culture of supporting conservation and natural areas, and we need to continue passing that vision new township residents and the next generation. I hope to see you there, whether you’re a township resident, a regular user of our parks, representing another local park system, involved with a garden club, on the faculty at a school or university, or just love our parks! We want all of our “stakeholders” to have the chance to provide input.
See you next Wednesday!
Natural Areas Stewardship Manager, Oakland Township Parks & Recreation
This post was written by our stewardship technicians, whose season officially ended at the end of September. We are thankful for their contributions to keeping our natural areas beautiful!
As the season for the summer crew ends, we would like to thank Alex and Marisa (seasonal land stewardship technicians) and Alyssa (our former Stewardship Specialist) for all of their hard work. Grant started as a seasonal technician this year, and will be staying on as our new Stewardship Specialist. They got hands-on experience natural areas management, obtained different certifications, and gained leadership experience that will help in their future endeavors. Our crew always had a positive, hardworking attitude that we will miss! We wish you all the best of luck!
During this field season, the crew gained experience with many tasks. The season started with the installation of new nest boxes and the restoration of old ones at Bear Creek Nature Park, Charles Ilsley Park, Draper Twin Lake Park, and along the Paint Creek Trail. These boxes were set up for the purpose of increasing the bluebird and tree swallow populations. An enthusiastic group of volunteers monitored all of the boxes through from April to August!
Then it was straight into garlic mustard removal. The crew pulled garlic mustard from many parks like Cranberry Lake Park, O’Connor Nature Park, Blue Heron Environmental Area, Stony Creek Ravine Nature Park, and many others. It takes quite a long time to remove garlic mustard from these parks, but it is truly necessary to prevent its detrimental effects in mature forest. We found less garlic mustard this year, so our persistent work seems to be paying off! If you would like to know more about garlic mustard, how to identify it, or more please visit the Midwest Invasive Species Information Network website.

During this season, the crew completed native landscaping at Gallagher Creek Park around the new playground. They were able to plant over 25 different species of wildflowers, grasses, and sedges, as well as six species of trees and shrubs. The purpose of the native garden beds is to help educate the public on different kinds of native species that they could use in their own landscaping. It was also planted with pollinators in mind, including bees and monarch butterflies. We even found some monarch caterpillars on the butterfly milkweed in August! Don’t forget to check this area through the year as this cool mix of native plants continually repaints its canvas.
Our next big task was controlling crown vetch (Securigaria varia) and swallow-wort (Cynanchum species) in the parks. These two species are a high priority for us, so we treat them anywhere we find them in the parks. Like garlic mustard, they are aggressive, and beat out native species for nutrients and space. The control was done using herbicides due to the ineffectiveness of hand pulling, mowing, and burning.
After that the crew moved on to do woody invasive species control, including common buckthorn, glossy buckthorn, privet, honeysuckle, oriental bittersweet, and autumn olive. This control was mainly done at Bear Creek Nature Park using the cut stump technique. The crew was able to get through a large portion of the park, as well as put a large dent in the glossy buckthorn that has taken over the area around the marsh on the north side of the park. Like most invasive species, both buckthorn and autumn olive have a tendency to out compete native species, take over areas, and become detrimental to the health of the ecosystem. Buckthorn can lower the water table in wetlands, and secretes a chemical that interferes with amphibian reproduction!
Some smaller tasks that were completed were our yearly photo monitoring of several parks including Gallagher Creek Park, Charles Ilsley Park, Draper Twin Lake Park, Stony Creek Ravine, and a few others. These photos are for our records to see the changes in these areas over time. We also completed our lake monitoring (Secchi disk and total phosphorus) which was done through the Cooperative Lakes Monitoring Program (CLMP). This is done to monitor the quality of the lake and help identify problems.

The crew had the opportunity to attend workshops throughout the season including one that focused on the Eastern Massasauga rattlesnake, a chainsaw safety workshop, and a wetland grass identification training. They also received several different certifications including first aid, CPR, herbicide applicator, and chainsaw safety and use.
Throughout the summer, there have been several different volunteer workdays and Wednesday bird walks. These include garlic mustard control, woody invasive species control, and providing assistance for our native plantings. We would like to extend a big thank you to everyone that came out and helped us at these different volunteer work days. The Wednesday bird walks are lead by Ben, the Natural Areas Stewardship Manager, and take place at a rotation of five parks. If you are interested in volunteering or attending the bird walks, please check our the website pages linked above or the parks newsletter for upcoming events.
It has been a long field season, but the crew has managed to complete a lot this summer. It is rewarding to see all that we accomplished! Be sure to be on the look out for the occasional update this winter from Ben or Grant, the new Stewardship Specialist.
