On my way back from up North, I saw a ton of signs that said STOP THE PHRAG, or PHRAG– like the photo below:
I looked into what this campaign was about. They are a group of people that are trying remove phragmites- an invasive species. Feel free to check out more at stop the invasion. If you see any phragmites you can go and plot them on a map and see all the sightings in you area. It is a great way to get involved in some citizen science activities.
