What is This Tool?

This interactive tool provides photographs, text and keys that aid in determining whether or not an unknown disseminule (e.g., seed, fruit) found as a contaminant in imported botanicals and agricultural products is a Federal Noxious Weed (FNW) and is therefore actionable. The total FNW list of 114 taxa is broken down into smaller groupings, first by Disseminule Type - Fruits & Seeds vs. Spores vs. Vegetative. Within Fruits & Seeds, these angiosperm taxa are further broken down into three family groupings - Poaceae, Fabaceae, and Other Families - each of which is accompanied by a key for further discrimination. A Key to Keys assists the user in deciding which of the three family keys is appropriate to use for taxon identification. Fact Sheets for each FNW taxon pull together relevant descriptions, including distinguishing characteristics and photographs.
