Note: The complete composite invasive plants report ("all" option above) is from 4-6.5MB of data and it loads slowly because it is large. Download and display time ranges from 4-20 minutes (or longer) depending on your internet connection, internet traffic, your computer and browser. Some computers may not be able to display the "all" reports at all. On Windows machines, the Task Manager may report that your browser is "Not Responding" until the entire report is formatted. Generally these problems do not occur with the individual reports or the composite reports viewed by alphabetical segment.
