Invasive and Problem Plants of the United States
Choose a species

Problem plants are all around us. We must learn how to identify them and how to control them. As part of an initiative to create a Plant Management Information System, the US Army Corp of Engineers has developed a database of invasive plants. This website is designed for myself (Rob Nelson) to organize and video-document these invasive plants. While this website is available I'll be documenting the species I have recorded and which I need. I have included distribution information so that I can remember where they are found. All of this I put on the web so that I have access to it from wherever I may travel to find them.
