[MAIPC] 03/02/18 Weather Alert: High Wind Warning

Mon Mar 19 07:50:26 PDT 2018

Ruth,

Thanks for the article. You make a really good point that electric
companies should be interested in this. I think we should endeavor to
educate them and highway, railroad and other transportation agencies, parks
and recreation agencies, city managers, home owners and many others on this
issue. We need to develop a more targeted educational campaign backed by
science rather than anecdotal observations.

Vine-laden trees being more prone to falling is something that seems
obvious to us in the invasive plant management arena and something we've
suggested for years but we need research to back this up. Trees fall for
reasons not related to vine coverage (weak root structure, poor soil
conditions, rot, flooding, intense storms and strong wind events, overly
wet conditions, etc.). Research is needed to document how vine growth and
weight on healthy trees makes them more vulnerable to falling, how vine
growth  impacts/reduces the health of host trees, weakens them, kills them,
and makes them more vulnerable to toppling. Comparing the impacts of
different species of tree-climbing vines, both native and
non-native/invasive, would be very helpful.

I wonder if any schools might be interested in pursuing this. It's
certainly worthwhile and would provide the science-based foundation for an
educational campaign.
