Amur Honeysuckle (Lonicera maackii ) was imported as an ornamental. It has been widely planted for wildlife cover and soil erosion control but it escaped from plantings and began spreading. Honeysuckle impedes reforestation of cut or disturbed areas and prevents reestablishment of native plants. It leafs out earlier than most natives and form dense thickets too shady for most native species. Honeysuckles provide some nutrition for birds and rodents but cannot compare to the lipid-rich fruits of native species that migrating birds need.

Chinese Privet (Ligustrum sinense) Chinese privet is highly invasive on disturbed sites, such as after a timber harvest, or along fence rows and forest edges.  This plant can outcompete native plants and quickly overtake an area, creating very dense thickets, and has been shown to have detrimental effects on wildlife and native flora.  Prevention is the best management.  Several mechanical control options, such as hand pulling, mowing, or cutting, may be effective, but to effectively eliminate this plant the roots must be removed.
