The Urdenbach Marshes in Summer

Yesterday I biked down to the Urdenbach Marshes south of Düsseldorf. It's a large nature reserve which used to be on the path of the Rhein until the river made a curve. City planners are now diverting brooks in the nature reserve to allow it to revert to marshland. It's now home to plenty of waterfowl, and the authorities are even planning to introduce water buffalo, although the locals aren't all that thrilled and may stop the plan. Unlike marshes in most parts of the world, this one isn't full of things that want to kill you. The sweet, intoxicating odor of decay and burgeoning life is everywhere. Before I move on to the pictures, one bleg: can anyone identify the light-purple labiate flowers? They're everywhere near the raised path. I looked everywhere, but could only find flowers which look a lot like these, but not quite the same. Frustrating.

  1. “Asiatisches Springkraut” is what it’s called in my area. An invasive plant and a nuisance. Spreads rapidly, preferring a moist habitat, to the detriment of native species. I have spent hours eradicating it. However, as the photo reveals, it’s also a source of food for bees, especially in late summer.

    A local forester claims it was brought to Germany by planes arriving from Asia lowering their landing gear, resulting in a shower of impatiens glandulifera seeds. It is more likely that it spread from England, where it was first introduced in 1839.
