Spent the weekend on the shore of Lake Michigan uprooting Phragmites australis, an invasive reed that is taking over expanses of beach and low-lying roadsides in Wisconsin. It's also found in Minnesota.
Phragmites is a semi-aquatic plant common around the world and not always regarded as an invader. In places in Germany, they still use it for roof thatch. Baby Moses may have been left in a Phragmites boat. There are native species [light green in the photo] and more aggressive Eurasian strains [dark green].You've probably seen stands of it running in ditches or along railroad tracks.
In swampy lands, you may not give it any thought, but when 12- to 16-foot tall, dense reeds (from the Greek phragma for fence) start taking over your sand beach, it's war.
Eradicating the tenacious plant is a perfect task for a slightly obsessive personality. The tuberous rhizomes that propagate the stuff lurk about eight inches under the surface, sending pale tusk-like runners in all directions to form root balls, from which a clump of reeds springs.
It’s fun digging down into seemingly benign areas and discovering the fugitive tubers, pulling them up through the sand and tossing their carcasses in a pile.
But eventually, they escape across the border into the neighbor’s land. Neighbors, it turns out, who tolerate the Phragmites. A collaborative effort to enlist all the landowners on this beach was only partially successful. Some used herbicide, some topical cutting, one brought in a farmer with a cultivator. Some did nothing.
They had other priorities.
Trusting to the free market, we are told, is better than relying on the government to solve problems. Often, that’s true. But sometimes, collective action is the only way, as the staggered march of Phragmites across this beach attests.
