Describes research, methodology, and results from the monitoring of current invasive plant species problems. See Manager's Tool Kit - Monitoring for general resources and other species.

California Invasive Plant Council.
CalWeedMapper is a new Web site for mapping invasive plant spread and planning regional management. Users generate a report for their region that synthesizes information into three types of strategic opportunities: surveillance, eradication and containment. Land managers can use these reports to prioritize their invasive plant management, to coordinate at the landscape level (county or larger) and to justify funding requests. For some species, CalWeedMapper also provides maps of suitable range that show where a plant might be able to grow in the future. The system was developed by the California Invasive Plant Council and is designed to stay current by allowing users to edit data.

Conservation of Arizona Upland Sonoran Desert Habitat: Status and Threats of Buffelgrass (Pennisetum ciliare) in Arizona and Sonora - Final Report (May 25, 2006; PDF | 1.5 MB)
Arizona-Sonora Desert Museum.
Funded by the National Plant Conservation Initiative and administered through the National Fish and Wildlife Foundation, project #2004-0013-003.

Early Detection & Distribution Mapping System (EDDMapS)
University of Georgia. Center for Invasive Species and Ecosystem Health.
Provides distribution data at the State and County level and point locations. See the section Who's Using It? for mapping distribution in various areas of the country. Includes:

Early Detection & Distribution Mapping System (EDDMapS) - Alaska
Provides distribution data and abundance of exotic and invasive plant species in Alaska.

Early Detection & Distribution Mapping System (EDDMapS) - Mid-Atlantic Early Detection Network (MAEDN)
MAEDN is a vast network of land managers, field experts, citizen scientists, naturalists, gardeners and others interested in documenting invasive plant occurrences in the mid-Atlantic region for the purposes of early detection, improved management and better coordination. The region includes Delaware, Maryland, New Jersey, New York, Pennsylvania, Virginia, West Virginia and the District of Columbia.

Forest Inventory and Analysis (FIA)
USDA. FS. North Research Station.
The Northern Research Station FIA unit is responsible for creating and maintaining a comprehensive forest inventory for 24 States. FIA collects, analyzes, reports, and distributes data about the Nation's forests.

Invasions By Alien Plants Have Been Mapped In European Union (Jan 27, 2009)
Biological invasions are one of the major threats to biodiversity and in many cases they have considerable impact on economy and human health. For their effective management it is important to understand which areas and ecosystems are at the highest risk of being invaded. The first map of the level of alien plant invasions in European Union (PDF | 1 MB) was published in the Wiley-Blackwell journal Diversity and Distributions.

Monitoring Better than EDRR for Managing Many Invasive Plant Populations (May 22, 2009)
Montana State University.
Land managers may benefit from spending more time monitoring invasive plants to identify those that pose the greatest threat, according to a recent article in Invasive Plant Science and Management. The article, "The Rationale for Monitoring Invasive Plant Populations as a Crucial Step for Management (Abstract)," relates results from a study by Montana State University researchers.

Nebraska Mapping programs:

  • NRD Mapping Program (Eastern Nebraska)
    NRD MapMaker allows you to create rich custom maps in your web browser from a variety of geographic data - without the need to purchase expensive software. MapMaker is powered by GIS (Geographic Information System) databases compiled by a variety of local, state and Federal agencies.
  • Nebraska Weed Control Association Online Weed Management System
    A state-wide mapping system for all 93 counties in Nebraska. This mapping system creates a state-wide database of invasive plants information and maps them using ArcIMS. Each county weed control authority updates the information directly on the website from current inspections. Note, this may be the first state-wide mapping program of this type.

New York Metropolitan Flora Project (NYMF)
Brooklyn Botanic Garden.
Dozens of flora native to the New York region face extinction, a result of urban development and the encroachment of invasive plants from foreign lands, scientists from the Brooklyn Botanic Garden report. Hoping to revive plants facing extinction, scientists recently completed a 20-year project mapping species in every county within a 50-mile radius of New York, providing detailed information on the health of more than 15,000 native and nonnative species. See the for more information.
