This sheet describes the management approach and prescriptions to manage common reed, more commonly known as phragmites. Phragmites is a tall (8+ feet), rhizomatous, cool-season grass that grows in monocultures in wetland areas. The species is native to the northern hemisphere, including North America. However, exotic genotypes native to Europe and Asia are highly invasive in the eastern and central U.S.
The term 'exotic shrub' covers dozens of invasive species, including such notables as multiflora rose, autumn olive, shrub honeysuckles, Japanese barberry, privets, and the buckthorns. This sheet describes a general management approach and specific prescriptions to control most any of these exotic species.
Stiltgrass is an annual, warm-season, shade tolerant grass native to East Asia that is highly problematic in forest and other natural settings. This sheet describes the management approach and prescriptions for control.
Tree-of-heaven, or ailanthus, is a highly invasive, suckering tree species native to east Asia. Ailanthus is fast-growing, and will grow in sidewalk cracks, sun-baked subsoil, as well as verdant sites. This sheet describes the management approach and prescriptions to keep this pest in check.

There are a number of invasive biennial species, including garlic mustard (Alliaria petiolata), poison hemlock (Conium maculatum), and common teasel (Dipsacus fullonum). This sheet covers the management approach and prescriptions to control weedy biennials in natural area settings.
The label 'woody vines' covers a number of invasive species, including Oriental bittersweet (Celastrus orbiculatus), kudzu (Pueraria montana), porcelainberry (Ampelopsis brevipedunculata), and Chinese wisteria (Wisteria sinensis).
