Of the 104 exotic taxa occurring at DWNP, twenty-one have a high invasive rank, such as Ailanthus altissima, Alliaria petiolata
, Artemisia vulgaris, Conium maculatum, Dipsacus fullonum, Fallopia japonica, Lonicera spp.
2006) presented a novel evidence that antifungal phytochemistry of the invasive plant, Alliaria petiolata

As another example, the production of glucosinolates by the invasive forest herb Alliaria petiolata
(garlic mustard) has been found to decrease spore germination, root colonization and/or inoculum potential of arbuscular mycorrhizal fungi (AMF) (Roberts & Anderson 2001; Stinson et al.
The four exotics that are most invasive are Alliaria petiolata
, Lonicera maackii, Robinia pseudoacacia, and Rosa multiflora.
Although widespread, Alliaria petiolata
and Rosa multiflora are not as common at the arboretum as other localities we have examined.
The open field contains several small populations of Alliaria petiolata
(garlic mustard) and abundant populations of Lonicera japonica (Japanese honeysuckle) at the edge of the low, wet woods.
