* there are so many of these invasive plants that have been such a
problem in Ontario, but don't elicit appropriate panic in places where
they're just showing up! See http://www.pinicola.ca/nfv2004c.htm -
http://www.pinicola.ca/swalwpai.htm for a 2004 account of a local area
that's completely taken over, and is still spreading. Local naturalists
should rally, and prod gov't to action, to eliminate any colonies of
this plant which are found, or you'll be in Fletcher Wildlife Garden
territory of a perpetual struggle -

A biocontrol moth has been released in Ottawa last year, but it's not
expected to completely control the Dog-strangling Vine.
