Thanks for the thoughtful comment (and documentation!). I agree; invasives are a very complicated topic. I also agree that there are value judgments at play, and times where eradication might be necessary.
I think my concerns are more along the lines of what ‘invasive’ really means in a dynamic biosystem, especially given changes in climate/temperature/weather. I can’t speak as knowledgeably regarding invasive animal species, but when it comes to invasive plants and noxious weeds, I think there’s a strong argument to be made that the current model (eradication) isn’t practiced selectively enough, resulting in overuse of toxins (as well as wasted resources).
This also gets into the “natives vs. non-natives” conversation. I’m not a native species purist; I think the question should be more climate-based (i.e. what plants are native to a climate and its analogues) than geography-based.
I hope to go over some of these ideas in a little more depth in a future post, but I’d love to hear anyone’s thoughts, pro- or con-!
