It seems that the vegetation autocomplete isn't working with Firefox 4.0.1.  I haven't figured out what the problem is yet, but watch this space for updates if that is your browser of choice.  In the meantime, you could use Internet Explorere, Google Chrome, or Opera.

The Corps has posted version 2.0 of the regional supplement for the Atlantic and Gulf Coastal Plain region, dated November 2010, complete with all new dataforms.  This version has an option for 4 or 5 plant strata, just like the Eastern Mountains and Piedmont region.  WetlandForms.com is not yet using this updated version - we currently have the interim version loaded, dated October 2008.

Here is a direct link to the regional supplement: Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Atlantic and Gulf Coastal Plain Region (Version 2.0).

I haven't looked closely at the new dataforms to see if they are significantly different from the interim version.  Based on my experience with the other regions, I would expect very little change.  So hopefully we will have these new dataforms up and running in the next few days.

Update:  New form is working - click here for details.
