Fast Facts

  • Site established in Feb 2020
  • Invasive plant of focus: Chinese Privet
  • Least effective method of removal: pulling/uprooting
  • Invasive plants reduce the diversity of native plants in our forests which eliminates food sources for wildlife

An invasive plant removal demonstration site was established in a forested area at the UA Division of Agriculture System's Little Rock State Office in February 2020 because volunteers with Master Gardeners and Master Naturalists in Arkansas were curious about which methods might work best in their efforts to remove invasive privet.  The purpose of the demonstration is to evaluate the effectiveness of a variety commonly used methods of invasive plant control.  The primary invasive plant of interest to control at this site is Chinese privet (Ligustrum sinense).

Six treatments for plant removal are under investigation for privet removal effectiveness.  The treatments being evaluated include:

  • mechanical pulling (M)
  • cut stump and paint with glyphosate (CPG)
  • cut stump and paint with triclopyr (CPT)
  • foliar glyphosate (FG)
  • foliar triclopyr (FT)
  • control (C)

The demonstration is nearing its first year of data collection on the initial privet removal, and so far mechanical removal of plants by pulling or uprooting appears to be the least effective method.  All other forms of removal appear to be more effective than pulling.
