In addition, each of us can educate ourselves on what to look for and how to remove invasives on our own property to help prevent their spread. Why does it matter? We have dandelions and worms and they were once invasive species right? Think of the Asian carp. This invasive fish has taken over a key spot in the food chain and wiped out a lot of other species as a result. Plants like Kudzu may be more familiar but here in Michigan, Phragmites, Garlic Mustard, Swallow-wort and Oriental bittersweet are just as harmful! With plants, we need to be alarmed when that plant turns a local field or forest into a monoculture, overwhelming and destroying that food web. A dandelion will happily live alongside the grass in your yard but doesn’t cause the grass to die out, or wipe out the local population of birds or insects. Not so with invasives such as Phragmites (frag-my-tees), a huge, towering, water-loving reed. It will take over a wetland area wiping out cattails and native reeds that birds and mammals rely on for a food source. This is when we need to step in and fight!
Be careful to do your research. Pulling up a plant like garlic mustard and throwing it on the compost pile or in a ditch can do more harm by spreading the seeds. Also, some plants such as oriental bittersweet or swallow-wort have root systems that need to be completely removed. Each species is different and has a different method of removal. Also, don’t plant invasives as ornamentals such as Purple Loosestrife or a food source for birds such as Autumn Olive or Oriental bittersweet (American Bittersweet is ok).
Finally, if you have Phragmites, contact Highland Township to join in on the latest effort to combat it. Currently there is a grant that will provide for a contractor to remove Phragmites from your yard free of charge, or in common areas in subdivisions, public spaces, and lake areas. Please call Lisa Burkhart at Highland Township immediately (248-887-3791) to arrange to be part of this important initiative!
