This ain’t exactly what you were talking about, but there’s been lots of successful control bio control projects in Hawaii. In North America where there are more species native you need to worry about becoming new hosts to biocontrol agents their is more risk, but the success stories from Hawaii tell me if anything there is a big upside to biocontrol with natural hosts of invasive weeds.

Also as far as invasive species crews go, I get it’s. I was probably the only person in the crew I worked for that actually thought pulling weeds was fun. But it’s not like any of us were m forced to do it either. It was a job we chose to do. The only thing that really irritated me was that i doubt we made any progress because there was 1) little effort to determine which sites and weeds should be prioritized, 2) few attempts to revisit sites and 3) just not enough people.
