The invasive plant issue is extremely complex and crosses many discipline and commodity boundaries. Each has their own perspective… their own interpretation…and their own agenda when addressing concerns over the classification, use, and impact of invasive plants. Background information in this section includes: Executive Order 13112; National Invasive Species Council; National Invasive Species Council Management Plan; Invasive Species Advisory Committee (National); Two Symposia ”Linking Ecology and Horticulture to Prevent Plant Invasions” held in St Louis (2001) and Chicago (2002); and the Office of Technology Assessment, Harmful Non-Indigenous Species in the United States (1993). The intent of this section is to highlight information that will aid in our understanding and shape the way we address the issue. The information presented provides useful insight into identifying: how we as an industry can have a positive impact on minimizing the impact of harmful invasive plants; how we as an industry can address the issue both within and outside our boundaries; and equally important what we as an industry should expect as a set of standards in dealing with the issue from broad based collaboration with those outside our industry. 

Meeting The Challenge


National Invasive Species Council
January 18, 2001


Invasive species affect each of our lives, all regions of the U.S., and every nation in the world.
Society pays a great price for invasive species – costs measured not just in dollars, but also in unemployment, damaged goods and equipment, power failures, food and water shortages, environmental degradation, increased rates and severity of natural disasters, disease epidemics, and even lost lives. Stimulated by the rapid global expansion of trade, transport, and travel, invasive species and their costs to society are increasing at an alarming rate.

Executive Order 13112

Five-Year Review Of EO 32 On Invasive Species PDF

Five-Year Review of Executive Order 13112 on Invasive Species
Prepared for the Office of Management and Budget


Invasive species inhabit all regions of the United States and every nation. The price society pays for invasives is reflected not only in significant economic Due to the broad and complex nature of invasive species, many agencies and departments across the Federal Government play an important role in the response to invasive species. Because invasive species do not respect jurisdictional boundaries, partnerships and co- operation with State, local, and private organizations are critical. Instead of creating a new department or regulatory authority, the EO established the National Invasive Species Council (NISC) as a high-level, interdepartmental organization to provide leadership, planning, and coordination for current Federal programs.
Secretaries and Administrators of the 13 departments and agencies serve as the members of NISC. The Secretaries of the Interior, Commerce and Agriculture serve as Co-Chairs, reinforcing the importance of cooperation and coordination in every action of the Council. The EO also established the Invasive Species Advisory Committee (ISAC), which consists of nonfederal representatives and stakeholders who provide recommendations as well as input and consensus advice to NISC. The Secretary of the Interior provides support for a staff of six, and NISC member agencies have assigned detailees to provide assistance. Each NISC member is represented by a Policy Liaison who provides coordination between his or her department or agency and NISC.

This report details actions taken by NISC during its first 5 years to meet the goals and objectives of the EO:

  • Providing national leadership and coordination.
  • Monitoring the implementation of the EO.
  • Encouraging planning and action at the state and local levels.
  • Developing recommendations for international cooperation.
  • Developing guidance under the National Environ- mental Policy Act on invasive species for Federal agencies.
  • Tracking and enhancing efforts to document the impacts of invasive species.
  • Facilitating a coordinated information (data) sharing system.
  • Publishing a national invasive species management plan.

Harmful Non-Indigenous Species in the United States : OTA

Summary, Issues and Options September 1993 OTA-F-565

The movement of plants, animals, and microbes beyond their natural range is much like a game of biological roulette. Once in a new environment, an organism may simply die. Or it may take hold and reproduce, but with little noticeable effect on its surroundings. But sometimes a new species spreads unimpeded, with devastating ecological or economic results. This latter category-including species like the zebra mussel (Dreissena polymorpha) and the gypsy moth (Lymantria dispar)-is largely the focus of, and the reason for, this assessment.
