Invasive Plants


What is an invasive?

Here are a two definitions provided by the Ohio Invasive Plant Council:

...species that is non-native (or alien) to the ecosystem under consideration... whose introduction causes or is likely to cause economic or environmental harm or harm to human health. Invasive species can be plants, animals, and other organisms (e.g., microbes). Human actions are the primary means of invasive species introductions. - National Invasive Species Council

...usually characterized by fast growth rates, high fruit production, rapid vegetative spread and efficient seed dispersal and germination. Since these plants are not native to Ohio, they lack the natural predators and diseases which would naturally control them in their native habitats. - Ohio Department of Natural Resources, Division of Natural Areas and Preserves

Weeds can be persistent and aggressive, but that does not necessarily mean they are invasive plants. Again, from the Ohio Invasive Plant Council:

Weed--"A plant (native or non-native) that is not valued in the place where it is growing. Any plant that poses a major threat to agriculture and/or natural ecosystems within the United States." - USDA, NRCS (Connecticut)

Noxious Weed--"A plant that is particularly troublesome. Any plant or plant product that can directly or indirectly injure or cause damage to crops (including nursery stock or plant products), livestock, poultry or other interests of agriculture, irrigation, navigation, the natural resources of the United States, the public health, or the environment." - USDA, NRCS (Connecticut)

Invasive Plant Descriptions and Identification

Ohio Invasive Plants Council (OIPC) Excellent resource!!
The Ohio Invasive Plants Council is a coalition of agencies, organizations, and individuals throughout Ohio concerned about the introduction, spread, and control of invasive, non-native plants in Ohio's natural habitats.

Midwest Invasive Species Information Network (MISIN)

  • Ohio page

  • Species Information Sheets (plants)

  • Species Training Excellent resource!!
    The invasive species education modules will help you become more comfortable with identifying these species in the field. Each module includes a short ten question quiz at the end to help you assess your newly acquired knowledge. Completing a module should only take about 15 minutes.

  • MISIN smartphone app
    Identify and report 400+ invasive plant and animal species, capture and submit species observations from the field, include images taken in the field with your observation, and browse images and species information on the top Midwest invaders.

EDDMapS is a web-based mapping system for documenting invasive species and pest distribution. Launched in 2005 by the Center for Invasive Species and Ecosystem Health at the University of Georgia

National Invasive Species Information Center

Invasive Plant Atlas of the United States
The purpose of the Atlas is to assist users with identification, early detection, prevention, and management of invasive plants. Four main components are species information, images, distribution maps, and early detection reporting procedures.
