Jill, you're paragraph on why trees fail and the need for additional research is right on! Jessie Strother

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. Jil  Jil SwearingenInvasive Species ConsultantIn the Weeds

I grew up in NJ so have always noticed information about the state. After Hurricane Sandy, I saw an article online (can’t recall where) about trees being felled due to invasive vines that had grown up on them. Today, I googled “New Jersey trees felled by vines during Hurricane Sandy” and came across an article that refers to this issue: http://www.njaudubon.org/SectionConservation/StewardshipProgam/StewardshipBlog/tabid/2006/categoryid/27/page/5/Default.aspx. Scroll down to see an article about a NJ power company and invasive vines. I should think that electric power companies would be very interested in this topic.

Marc -
This is good information. Can you give us citations to the studies you refer to?

Marc,
 
Have you worked up a presentation on trees weakened by invasive vines? I would be interested in reading anything you have put together.  I know you had talked earlier about this being a prime topic for research. 
 
Thank you for raising this issue!

At the Strawberry Hills Civic Association meeting on March 12 and at the Maryland Invasive Species Council meeting yesterday I reported that studies indicate that we can prevent about half of the trees from falling down over highways during a major storm for about 10% of the effort to control them all. It just takes 10 minutes to cut stump the non-native invasive vine, such as oriental bittersweet, at ground level and apply glyphosate to the cut stump. At the SHCA meeting it was reported that trees came down over electric power lines causing the electric power outage and subsequent brush fires.

Marc,
Wind load was assuredly a factor for vine-laden trees, evergreen ivy or not.  I personally observed 4 downed obstructive roadside trees in my travels on state or county roads in 2 counties that Friday.  All White Pines.  No surprise there.
 
To my knowledge, no, SHA has not conducted such a study. However, NCHRP is proposing a research study to develop protocols for removal of hazardous trees along the roadside.  It may not specifically address vines, though.
 
Thanks for asking.
Shelley

Excellent idea.

I did a study of the first 5 trees I found that had fallen down over highways causing traffic to stop because of the Friday March 3 wind storm. The first was strangled by oriental bittersweet, the second by oriental bittersweet, the third no vine found, the fourth American Grape, the fifth Japanese honeysuckle. About 8 years ago 7 trees came down in a February storm. All were strangled by English Ivy in a 30 acre park. No other trees came down. 
 
So let us do a statistical study after the next gross storm.

I have not yet seen trees come down in the parks where volunteers removed all the non-native invasive vines that would otherwise strangle and weaken them, including English Ivy, Oriental bittersweet and Japanese Honeysuckle. Would it have cost less for our government to have spent the $ with preventive care than what it cost yesterday restoring roads, buildings and hospital visits.

Potential Hazardous Weather Conditions
 
 
The National Weather Service has issued a High Wind Warning for Prince George’s County and Montgomery County, which is in effect from 7 AM Friday to 6 AM EST Saturday.  The strongest winds will be Friday afternoon through Friday evening, and are predicted to be 25 to 40 mph, with gusts around 60 to 70 mph. 
 
Individuals and M-NCPPC facilities should prepare for the possibility of damaging winds that may blow down trees and power lines.  Also, widespread power outages are expected. Travel will be difficult, especially for high profile vehicles. 
 
Staff is asked to monitor forecasts and be prepared to take action should warnings be issued.  
 
Preparing for Strong Wind Gusts:
 
·       Bring Loose Items Indoors.  Objects left outside in wind storms can either become projectiles and potentially injure people and property, or the objects themselves can be lost, damaged, or ruined. It is important to remember that nothing is more important than the safety of people, so objects should only be brought indoors if it is safe to do so.
 
·       Secure Large Outdoor Objects.  Some objects will simply be too big to safely bring indoors in the event of high winds, but even if they are too large to bring in, they can still be affected by wind. If possible, these items should be anchored and secured.  Objects to consider include signs, tables, chairs, large umbrellas, play structures, watercrafts, garbage cans, and much more. There are many ways to safely secure these objects, including weights, ropes, chains, and stakes.
 
·       Close and Secure Doors and Windows.  Closing windows and doors is a simple step that can be easily forgotten while everyone is securing objects, collecting their belongings, and heading indoors. Open windows can result in water damage or broken glass. If there are shutters, it is important to close them. Also, close and secure doors since strong winds can easily rip them from hinges.
 
M-NCPPC Notice 11-08 Please see M-NCPPC NOTICE 11-08, “Preparation, Staffing, and Compensation During Emergency Conditions,” Which outlines further steps to follow in the event of a weather emergency.
 
In the event of an accident or injury, call the Risk Management and Workplace Safety Office as follows:
 
·       During regular hours
301-454-1686 or 1692
 
·       After hours 
301-275-5125 or 240-393-0419
