Uninvited guests: When invasive species attack
Mile-a-minute weed – it sounds like a gardener’s worst nightmare. But it’s also a nightmare for county roads.
This plant is one of Michigan’s invasive species – a threat to Michigan’s economy, environment, human health and roadways. Sure, this probably isn’t the first time you’ve read about invasive species. But did you ever consider the impact they have on roads?
Invasive species are not native to Michigan and are a big threat to the right-of-way. They can take over important parts of the road and disrupt drainage systems, making roadways unsafe for the motoring public.
So, how do road agencies get rid of these pesky, uninvited guests? Invasive species can be controlled through chemical and mechanical treatments, which include applying herbicides, mowing and prescribed burning.
These intruders won’t be leaving Michigan any time soon, but road agencies are tirelessly working to control invasive species growth and maintain the right-of-way.
