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, a European invader of North American forests, suppresses native plant growth by disrupting mutualistic associations between native canopy tree seedlings and belowground AM.
Cavara & Grande; SYN: Alliaria
The invasive species garlic mustard, Alliaria
petiolata, has negative impacts on understory forest species in the Midwest.
The habitats with little adventive species impact include the floodplain woods (though the recent spread of Alliaria
petiolata is worrisome), the wet sedge meadow (and fen), mesic ravine woods, dry to mesic upland woods, and the circumneutral seeps in the recently purchased woodland.
Allelopathic inhibition of germination by Alliaria
The non-native Alliaria
petiolata (garlic mustard), a pervasive adventive species of many Illinois sand deposits, was occasionally found in the shaded seep plots (IV of 2.
