Absence of data does not necessarily mean absence of the species at that site, but that it has not been reported there. Other aspects of the forest ecosystem may be altered due to the change in the vegetative community tied to garlic mustard invasion. For more information on chemical control see the Best Management Practice on Garlic Mustard (below). Garlic mustard is on the Restricted weed list. Some researchers also believe that these compounds may hinder the beneficial relationships some plant species have with soil fungi (Roberts and Anderson, 2001). Garlic mustard has a biennial life cycle, that is, it takes two years to fully mature and produce seeds. Any plant materials should be placed in black garbage bags or yard waste bags. This map shows confirmed observations (green points) submitted to the NYS Invasive Species Database. Plants that have been mowed can still send up flowering stalks, but continuous mowing throughout the growing season can prevent seed production. Garlic mustard is an invasive non-native biennial herb that spreads by seed. It can grow in very shaded areas, which enables it to live in many different ecosystems. Basal cutting is preferable to hand pulling because it reduces the soil disturbance. In its natural habitat garlic mustard is eaten by insects and fungi.

An invasive species can be any kind of living organism—a plant, insect, fish, fungus or bacteria—that is not native to an ecosystem and causes harm. Dispose of invasive plants in the garbage. Garlic mustard leaves have a high nutrient content. Non-native species are able to grow and displace native seedlings, including those which would eventually become canopy trees such as maples and oaks. Garlic mustard can take over the forest under story displacing native plants and interfering with growth of the remaining plants. The BMPs were developed by the Ontario Invasive Plant Council (OIPC), and its partners to facilitate the invasive plant control initiatives of individuals and organizations concerned with the protection of biodiversity, agricultural lands, infrastructure, crops and natural lands. Garlic mustard (Alliaria petiolata) is an herb from Europe that was likely introduced for use in cooking. Garlic mustard may also affect the tree composition by creating a selective barrier that some seedlings, such as the chestnut oak (Quercus prinus), may not be able to overcome (MSU, 2008).

Garlic mustard is allelopathic; the chemicals produced in the roots have been shown to prevent the growth of other plants and grasses. Well, this cool-season, biennial herbaceous plant, is now taking over the forests and woodlands of Ohio and its surrounding states. By changing the composition of the litter layer on the forest floor, garlic mustard reduces habitat for ground-nesting birds and affects habitat for salamanders and other forest floor-dwelling animals. This spread has allowed it to become the dominant plant in the undergrowth of some forests, greatly reducing the diversity of all species. Garlic mustard does not appear to require disturbance to become established, making it a threat to mature forests. Garlic mustard is native to Europe and is found from England east to Czechoslovakia and from Sweden and Germany south to Italy. Mature flowering plants reach 3.5 feet tall, although shorter flowering specimens may be found.
