The Global Invasive Species Team...
...is part of The Nature Conservancy's response to abating the damage caused to native biodiversity by the human-facilitated introduction of non-native, harmful invasive species. This web site provides many resources designed to help all conservationists deal most effectively with invasive species.

Web Site Being Archived
Because of budget cuts, The Nature Conservancy's Global Invasive Species Team was disbanded in March 2009. One result of this is that the GIST web site, long housed at the University of California, is no longer being managed. However, the fine folks at the University of Georgia have offered to maintain the site in their archives. All Hail University of Georgia, Bugwood.org, and Invasive.org!
Note, however, that this site is no longer active--you are reading pages of a civilization past. For more recent documents, you must look elsewhere.
Our fine web site contains many very useful, important documents on invasive species control. However, these documents are static and increasingly old; some are very much out of date.
As a bold experiment by the Team, Barry Rice has launched an invasive species wiki to keep these documents up to date. If you are an expert on some species of plant invader (either an academic or field worker), and would like to help, please help update, refresh, and expand our content. The wiki approach is an exciting and interesting way to keep our documents up to date, based upon your expertise! Very exciting, don't you think?

Cool Green Science Blog
The Nature Conservancy has just launched a new blog site, called "Cool Green Science"! Bloggers on the site write about the whole palette of conservation issues, so there is plenty to read about. Of course, if you are interested in invasive species, you should immediately examine the latest blog-musings of Barry Rice, from TNC's Global Invasive Species Team. Chances are that he's got invasives on his mind.
Invasives at Cool Green Science
Remote sensing is all the buzz. Fans tell you that it will solve all your problems; detractors say that it is an expensive waste of time. What is the Truth? To help you find out for yourself, the GIST's own Barry Rice has written an primer on remote sensing. More of an introduction to concepts than a detailed guide, it includes a useful glossary, review of the science involved in remote sensing, and thumbnail descriptions of the major remote sensing satellites. If this is well-received, GIST will be expanding its remote sensing coverage with additional content such as reviews of remote sensing projects, and a bibliography, and more.

Weed Control Methods Handbook
This popular handbook provides detailed information on the use of manual and mechanical techniques, grazing, prescribed fire, biocontrol, and herbicides, to help you control undesirable invasive plants. Now it is even better than ever, since several chapters have been updated and a NEW chapter on those-ever mysterious "herbicide adjuvants" has been added. You can download individual chapters, or the entire handbook in a single zipped file!

Weeds Information Management System v. 3
The very popular Weeds Information Management System (WIMS 3) is a Microsoft Access-based relational database application designed to assist natural resource managers in managing their weed-related information. This updated version is compatible with both ArcPad 6 and 7, has several new features to aid in the collection and maintenance of weed mapping and management data, and is available here for free! New and updated training documents are also available!

Rod Randall's Weed Database
The Global Invasive Species Team is proud to host the enormous database of invasive species information accumulated by Rod Randall. This database includes many citations of plants acting as invasive species in wildlands. If you are curious to learn if a plant is a weed someplace, Rod's database is a great place to start your search

Do you have a specific invasive you are trying to control? Here is where you will find many documents that tell you how to deal with specific organisms. (These are also the links to follow if you seek the species management summaries called "ESAs.")

Gallery of Pests
Profiles of more than thirty pests and pathogens that are threatening the native forests of North America. From entrenched invasives to new arrivals, and even a few that have apparently been extirpated, they are all here. Are you confused about the differences between the balsam woolly adegid and hemlock woolly adelgid? Or the European oak bark beetle vs. the European spruce beetle? You need look no further than the Gallery! And if we missed some favorite pest, contact us and we will take your suggestions (But beware! We may try to convince you to help us write a blurb about it).
