When a non-native plant enters a natural habitat and begins reproducing so rapidly that it takes over to the detriment of existing flora, it is classified as invasive. Invasive plants are controlled at The Arboretum in natural and restored ecosystems to promote the biodiversity of species—both flora and fauna.

Removal

With the assistance of dedicated volunteers, Arboretum staff aggressively work to remove non-native, invasive plant populations. Whether utilizing mechanical and chemical methods on large areas of invasive plants, or intensively hand pulling individual plants within The Arboretum’s natural areas, invasive plant control requires a great amount of time and resources.

Below is an example of invasive plants we are addressing:

  • Amur corktree
  • autumn elaegnus (or autumn-olive)
  • barberry
  • broad-leaf cat-tail
  • buckthorn
  • Callery pear
  • Canada thistle
  • castor-aralia
  • English ivy
  • garlic mustard
  • honeysuckle
  • Japanese pachysandra
  • multiflora rose
  • narrowleaf cat-tail
  • oriental bitttersweet
  • periwinkle (or myrtle)
  • privet
  • purple loosestrife
  • Siebold viburnum
  • teasel
  • tree-of-heaven
  • winged euonymus
  • wintercreeper

 Ongoing Maintenance

Invasive plant control within all Arboretum properties and ecosystems is an ongoing project of high importance for The Arboretum and will continue to be so in the future. As members of the Ohio Invasive Plant Council, Arboretum staff and volunteers use the most up-to-date and best management practices for their removal.
