Plant ID Guides

It is essential to have good references if you are  going to identify the vegetation on your property. There are several good books available with great color pictures and descriptions. The Weld County Weed Division staff have access to these books and can use them to help you. If you want to own your own set of books the order forms are attached on the right column.
