I've been part of this forum since it started last year and read postings on a couple of others as well. I work as a conservation biologist so I am involved in invasive species management quite a bit. I like to keep in touch with how individuals and organizations are dealing with pests and their perspectives on native plant/exotic plant uses. One thing I have noted though is that the fall back to pesticides or chemical treatments is still getting suggested frequently (moreso on other forums but this one as well) as a means to deal with problem plants. I know they are convenient but its something I am hoping that horticultural enthusiasts will consider moving away from. Those of us who do a lot of restoration of natural systems and work to protect amphibians and insects as well as a host of other creatures are trying to get the general public to reduce their dependency on such toxins. I do support their use in some instances, but I've found that there are a lot of viable naturally derived alternatives out there (from acetic acid to saponied fatty acid soaps) that if used properly are less likely to have ripple effects in the environment. Goats, cows, donkeys and especially people power are excellent ways to raise the profile of invasive species and help get the public engaged in the issue more than a quick spritz of a neuro toxin ever could.
