Since the 2007 Symposium, the US Army Corps of Engineers invested in further research by its Engineer Research and Development Center (ERDC) to study the effects of woody vegetation on the performance of earthen levees. Simultaneously, the California Roundtable for Central Valley Flood Management (formerly the California Levees Roundtable) formed the California Levee Vegetation Research Program to research gaps in scientific knowledge not addressed by the ERDC studies. Other relevant research on the effects of vegetation on levee integrity continues nationally and internationally.
On August 28-30, 2012, a second Levee Vegetation Research Symposium will be held in Sacramento to take stock of what as been learned over the past five years.
