Another excellent post! Well cited, informative, clearly written! One of the most striking things about invasive plants, is they often times don't appear to the standard observer, like they would be a problem. You are showing photos here of beautiful vegetation, but the issues lie beneath the outer beauty. When a species has no natural predators, it's population blooms exponentially, damaging the delicate ecosystems of the areas they invade. You are doing a great job providing examples of this!
