The purpose of the Rangeland Invasive Species Committee is to serve the Society for Range Management (SRM) by focusing attention, sharing knowledge, and communicating concerns about rangeland invasive species.

What is an Invasive Species? As defined by the National Invasive Species Information Center (NISIC):

An 'invasive species' is defined as a species that is 1) non-native (or alien) to the ecosystem under consideration and 2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health (Executive Order 13112). Invasive species can be plants, animals, and other organisms (e.g., microbes). Human actions are the primary means of invasive species introductions.

Invasive rangeland weeds have rapidly moved to the forefront as a concern in management of rangelands. Invasive plant invasions are changing landscapes at a rapid pace, threatening native plant and animal species, and often impact human well-being. They are capable of reducing biodiversity, habitat for wildlife and native plants, and altering ecosystem function across broad scales. Exact economic impacts of rangeland invasive plants are difficult to quantify, but include reductions in land value of infested areas, loss of production and income, costs of controlling invasive plants and job losses.
