Wisconsin County Distribution Map  The small county map reflects information from Wisconsin Botanical Information System (including records with only county information) as well as the Wisconsin Floristic Atlas Project's hand maps. Therefore there might be county records (when available-) not reflected in the larger map.
Change Background map to:  
 Original vegetation 
 Counties   Soils   Bedrock   Ice Age Deposits   Land Forms   Ecological Landscapes   Early vegetation 
(NEW) Change Dates: Enter a year between 1800 and the present. The resulting map will display all collection to that date. These results reflect only databased collections with valid dates.

Detailed Distribution Map Information
This map reflects the specimen location information from the Wisconsin Botanical Information System database and attemps to line up the original Town-Range Survey map from 1833 to 1866 with a computer generated table grid over the map of Wisconsin. Because the original Town Range lines are inexact, these "dots" might be somewhat skewed. Also townships near the borders of the state might only be partial, so the "dot" might center outside the state's boundry.

Holding the mouse over the "dot" identifies the Town-Range.
Clicking(new window) on the "dot" will link to a list of all specimen accession numbers for this location. You can then link to the individual specimen's label data.

Arrange this window side-by-side with the specimen-list window so you can easily go back and forth between this map and the specimen's data.
