According to this Tampa Bay Times article, the foundation purchased 350 sections of 8’x3′ wall, salvaged from the Checkpoint Charlie area. At the time, it was purported to be the largest collection of the Wall in the world.
The intention was to create something beautiful out of something ugly. I’m not sure whatever became of the plans for the 100 different art installations but, having visited the Checkpoint Charlie museum I’m glad this reminder remains.
From my years of experience fighting Buffelgrass (a noxious weed out west) I know that battles like this require multiple modes of attack. It’s easy to see why manual removal is not an adequate measure.
There are several herbicides that have proven effective and the USDA has authorized use of the Tropical Soda Apple Leaf Beetle (Gratiana boliviana) as a biological pest control. Currently, there is also a natural, biological herbicide being developed for control TSA though it is not yet available for public.
Next time I see one of these out on the trail, regardless of all the spines, I’m pulling it up!
