I suggest that the MMWD board be made to drink Roundup on a daily basis, since they think it is so grand.

Valeri, thank you so much for posting this and aiding our community. I plan to be there.

"Biological control offers the only economic solution for long-term reduction of existing [Broom] infestations." Although the pervasive invading weed is French Broom, there have been positive results regarding Scotch Broom biological control. "One research study from Oregon found that E. fuscirostre attacked 40-60% of pods and that of those pods attacked, 85% of the seeds were destroyed. In California, seed production was reduced by 60%." "Initial findings from research on B. villosus ongoing in Oregon (where the beetle is relatively new) show that 10-25% of seedpods have been attacked. In North Carolina, where the beetle has been established for many years, more than 80% seed reduction is reported." Unfortunately, it takes at least 5-7 years for a biological control insect population to be large enough to impact the broom infestations, so we have to start implementing the process as soon as possible. I read in yesterday's IJ that the plan that forgoes herbicides would cost the district $5.8 million per year, while the plan with herbicide use would only be $1.6 million per year. I don't think health concerns alone will sway the decision for a program free of herbicides. We have to also present an alternative that will be economically feasible for the long term control and management of Broom.

Great idea Tony, and I wonder, worry, about, what effect will the beetle have a few years down the way? Nature is such an intertwined web of diversity......

I agree. It can be tricky. I'm still doing the research. Some studies have been started, and some are lost in limbo due to lack of funding. I don't quite understand it. There's an International Broom Initiative, a California Invasive Plant Council, and a Statewide Integrated Pest Management Program, and so far the only really encouraging attitude for grazing and biological control is coming out of Australia. The report of more than 80% seed reduction in NC is mentioned by the King County Noxious Weed Control Proram, but I can't find any primary report from NC itself. My ultimate goal is to gather enough information together to present the MMWD with a fiscally sensible alternative to the herbicide use proposed in plan #2 of the WPHIP. Do I know what I'm doing? No, not really. But I'm willing to give it a shot. I think the insects deserve a fair evaluation and prefer their company to glyphosates.
