THIS WEEK IN STEWARDSHIP: Wetland Grass Identification is Fun!

While the crew was hard at work, one of the members, Grant, attended a wetland grass identification workshop through Michigan Wetlands Association. Dr. Tony Reznicek from the University of Michigan taught the class – he is widely considered a sedge expert (and a good teacher!), so it was quite a treat to learn from him. Over the two days of the workshop the group visited several wetland habitats to examine the wetland grasses occurring there. The class members were from different parts of the state, different organizations, and different stages in their careers, which made the workshop a great place to learn.

The first day the class visited a fen wetland where they identified a rich diversity of grasses. At this particular fen they found little bluestem (Schizachyrium scoparium), blue-joint grass (Calamagrostis canadensis), marsh wild-timothy (Muhlenbergia glomerata), and Indian grass (Sorghastrum nutans).

The next stop that day was a bog, where they saw a different set of grasses that grow in a bog compared to a fen. At this bog some of the highlight species were cotton grass (Eriphorum virginicum) and wool grass (Scripus cyperinus), as well as other species of plants like poison sumac (Toxicodendron vernix).

The final stop for the day was on the St. Joseph river, where they not only found an abundance of wetland grasses, but also the biggest ragweed (Ambrosia) field anyone in the class had ever seen!

The second day started at Warren Dunes State Park where the class got to see the many different grass species found in forested wetlands. During this stop, they saw rice cutgrass (Leersia oryzoides), deer tongue (Dicanthelium clandestinum), wood reed (Cinna arundinecea), and fox grape (Vitis labrusca, a rare viney species).

Then the group hiked through the dunes to an interdunal wetland, where one of the smallest bladderwort species in Michigan lives (Utricularia subulata), as well as Lindheimer panic grass (Dichanthelium lindheimeri), and Tickle grass (Agrostis hyemalis).

The final stop for the workshop was one of the best tamarack fens in Michigan. At this spot we saw many tamarack trees (Larix laricina). This stop has many species we had previous seen at different stops like Big blue-stem (Andropogon gerardii), Marsh wild-timothy (Muhlenbergia glomerata), and Indian grass (Sorghastrum nutans).

Unfortunately many of our wetlands are being degraded by invasive species like invasive Phragmites. Dr. Reznicek is holding a stem of this large wetland grass here.

Through this workshop, Grant got hands-on experience with many species of grasses. He also got to practice his grass ID skills – grasses can be some of the most difficult plants to identify! We continually improve our land stewardship skills so that we care for the natural areas in Oakland Township’s parks.

Photo of the Week: Phragmites Progress at Gallagher Creek Park

Human memory is a funny thing. We like to create our own versions of events in our minds, so when I need to track progress over time, I know that it’s important to have a separate, objective record. We regularly use photo monitoring to document changes in the natural communities in our parks. Most of the photo monitoring points were established in 2011, so we have about 7 years of photographic records. Not a long record, but long enough to see big changes in areas where we are doing active land management.

Check out this series of pictures from Gallagher Creek Park. These photos illustrate the growth of Phragmites patches until they were treated in 2014. We have done follow-up treatment every year. When I check each Phragmites patch before treatment, I am a little frustrated when I see Phragmites resprouts. But these photos remind me how far we’ve come. We plan to wrap up Phragmites treatment in our parks next week, so expect to see (or not see) smaller Phragmites patches in the future!

Phragmites, Knotweed, and Swallow-wort: Workshop TOMORROW to learn to ID and manage high-priority invasive plants!

Phragmites, Japanese Knotweed, and Swallow-wort can push out all other plants and ruin habitat for wildlife. Don’t let these invasive plants get a foothold on your property! Learn more about how to recognize and control these plants so that you can act quickly if you find them.

When: TOMORROW, June 27 at 6:30 pm

Where: Paint Creek Cider Mill, 4480 Orion Rd, Rochester, MI 48306

We will walk through the basics of identifying, controlling, and reporting high priority invasive species. These invasive plants are known to reduce property values, degrade natural areas, and impair wildlife habitat.

Phragmites does not recognize property boundaries! Catch your Phragmites while it is small and easy to control for the best results.

 

Phragmites Workshop: Thursday, June 18, 6:30 pm

Stop by Gallagher Creek Park, 2780 Silver Bell Rd (click here for map), at 6:30 pm tomorrow to learn more about Phragmites, its effects on our native ecosystems, and steps we can take to control this very large invasive grass. We will walk through the basics of Phragmites control, including identifying Phragmites, getting supplies, timing of control, getting permits, and the actual control work. The entire workshop will last about 1 hour.

Hope to see you there!

Protecting Gallagher Creek and its Brook Trout

Last Friday we conducted a prescribed burn at Gallagher Creek Park. Located near the headwaters of Gallagher Creek, this park protects our important water resources in our township. Notably, Gallagher Creek is home to a remnant population of native brook trout. In addition to stimulating the native plant communities at this park, the prescribed burn was part of our Phragmites control program (along with appropriate Michigan DEQ approved chemical control). We hope that managing for healthy native plant communities in the wetlands around the creek will help keep Gallagher Creek itself healthy.

The wetlands at Gallagher Creek Park filter runoff from our roads, lawns, and parking lots before it reaches Gallagher Creek. Natural water filters!

Surveys of the brook trout have been done by the Michigan Department of Natural Resources (DNR, formerly DNRE) in 1990, 1998, and 2010. The Southeast Michigan DNR Fisheries Newsletter from January 2011 provides this summary of what we know about the brook trout in Gallagher Creek:

Gallagher Creek is a small, coldwater stream originating just south of the Bald Mountain Recreation Area in central portion of eastern Oakland County. It flows in a northeasterly direction and empties into Paint Creek at Orion Road in the Village of Goodison. The creek flows through private land; there is no public access. This stream is home to one of the few remaining self-sustaining brook trout populations in southern Michigan. There were concerns that habitat quality had degraded due to sediment and nutrient inputs from erosion and runoff associated with development in the watershed. A survey in 1998 indicated that runoff from construction sites in the area was responsible for depositing sediment in the gravel riffles and natural pools formerly present in the stream. Previous surveys of this stream in 1990 and 1998 produced brook trout densities of 300 trout per mile. In 1992, mottled sculpin were trapped and transferred from Johnson Creek in Wayne County to Paint Creek as a prey item for trout. The sculpin had managed to expand their populations into the lower stretches of Gallagher Creek by 1998. This survey was conducted to evaluate the status of brook trout in Gallagher Creek. We captured a total of 7 brook trout from 6 to 7 inches and 1 brown trout at 3 inches. The brook trout density found in this survey was about 50 per mile, down from 300 per mile in 1990 and 1998. This decline in abundance is likely due to siltation of the stream from the development along the creek. Mottled sculpin have expanded their range even further upstream from 1998. We also captured blacknose dace during the survey. The presence of these two species indicates that the water quality is still good, but the heavy siltation is hampering the brook trout’s ability to reproduce.

Does our natural heritage, a special population of brook trout in this case, need to be sacrificed for the sake development? Or can we be smart with our development, designing systems that protect the stream by filtering runoff to capture silt and other pollutants?

Be part of the solution! Install a rain garden with native plants to capture the runoff from your roof and driveway before it enters our wetlands and streams. Plant a native plant buffer next to the wetland or stream that runs through your property. We have very special natural features in our township, and we all need to pitch in so that future generations can enjoy more than just stories about “the way it used to be.”
