How to use this Lookup Table

This table takes several seconds to load intially and to reappear after making filter selections.

This table allows you to search and filter for forb species with certain attributes. Most columns can be filtered using the second row of the table. Information is grouped into categories indicated and color coded according to graphic below.

Clicking on any row will bring up the entirety of data available for the species including a photo and distribution map of the species, descriptions for many of the yes/no columns, a link back to the complete species review, and more.

Empty cells indicate a lack of this information currently or as of the posting of the species' review.
