    • VEGETATION

  • Vegplot Text Note(s): Linked this Veg Plot to the KSSL site and pedon that was the same as the ones originally linked to this Veg plot (User Site ID and User Pedon ID 09CA624002). The site and pedon originally linked to thes Veg plot were not noted as KSSL pedons. The location information was however more accurate on 09CA624002, so that information was updated in the KSSL Site record.
