This is plant vandalism. These agave plants along the Yellow Trail in Camp John Hay keep getting vandalized. Some trail users seem to think that this is fun and harmless.
These cuts/scratches can disrupt a leaf's system. Rotting often starts at the points of impact then spread out. Some of the cuts are deep enough that the leaf can't fully recover. A hole appears which can enlarge until the leaf breaks apart.
Don't do this.
