Invasive plant documents & photographs

This page includes links to all our resources specific to individual invasive plant species. All of The Nature Conservancy's invasive plant species summaries can be downloaded here, including "Element Stewardship Abstracts" (or ESAs), which are particularly large, researched, and inclusive management summaries. Consider documents written prior to 1990 to be out of date---newer information is probably available. We also provide here shorter documents on invasive species.

For information on non-plant invaders, including pathogens, arthropods, vertebrates, etc., please refer to our invasives animal & pathogen page.

Didn't find what you were looking for? Try searching our listserve archives for information on the organism that interests you.

Are you an expert on a species not properly treated on our web site? (Perhaps our "ESA" for the species is dated or nonexistent?) Consider helping us all by following these instructions on how to contribute an ESA.

Unless otherwise indicated, the photographs on our site are copyrighted and property of the Wildland Invasive Species Team. If you would like to use some of our images, look at our usage policies on the page that houses our inventory of photographs.

Note our disclaimer regarding lists of species resources on our web site.

Search using Latin plant names

1)The first date after each taxon name above indicates when a Species Management Summary (i.e. "ESA", or "Element Stewardship Abstract") was last written for the organism.
2)"NA" means no ESA is available.
3)The second date indicates when we last added images or other documents relating to the organism.
4)We use Kartesz (1994) as our primary nomenclatural standard for plants.

Search using common plant names

1)See notes 1-4 above.
2)There are no standards for common names, but the USDA PLANTS database is commonly followed.
