Note from the author: This is a little tougher to lay out for quick reference, since it is a many-to-many list with lots of overlap, ie. a county might be in two bioregions. Right now, we have a handy little table provided to us by Karen Beardsley of ICE, and you may download that or look at these partial lists to decide which place names to use in your metadata. We will be working to add other regions soon, such as Watersheds.
