[MAIPC] Knotweed and honeysuckle species identification

Hi all,

I was just talking to some researchers, and the topic of differentiating invasive knotweeds and bush honeysuckles came up. I know I'm often guilty of just putting "Lonicera spp" or "Fallopia spp" when entering data points or taking notes. However, some researchers are working to find differences between these species' infestation habits or treatments options, and accurate/species-specific data helps them. This is especially for knotweeds (Japanese, hybrid, and giant), where future biocontrols may be targeted at the individual species rather than the genus.

So I promised the researchers that I'd put this reminder out to MAIPC, as well as other groups I work with.

Thanks all, and enjoy the rest of your summer!
