  1. Skunk cabbage: Physical removal

    A study in 2003-2008 in Switzerland (Buholzer pers. comm. (2009) In European and Mediterranean Plant Protection Organization 2009) found that annual physical removal of recently established skunk cabbage Lysichiton americanus plants over five years removed the entire stock. One hundred plants were removed in 2003, compared with 20 plants in 2004, and only a few individual plants in each of 2007 and 2008.  In 2007 and 2008, no more plants had germinated.  From 2003 to 2006, two people removed the plants by hand on an annual basis following which a monitoring programme was put in place to check for regrowth every second year.  Total costs to 2009 were reportedly around €1000, declining from €500 in 2003, to just monitoring costs from 2008 onwards.
