taking the time for writing such a detailed set of instructions.<br>
However, it is quicker for me to do it manually.<br>

If the process could be automated then of course it would be a
different matter.<br>
I am working only with the ferns - less than a hundred records.<br>
The flower plants are over 2500.<br>

Thanks,<br>

<font face="Georgia"> As first step towards building a model as
Nicolas has suggested:<br>
I assume you have a layer with the county boundaries. Export
this layer as a CSV file, keeping only the name of each county
in the export step, and don't export the geometry.<br>
Now open this file in your spreadsheet app of choice.<br>
Add a new column for each plant species.<br>
Put a one in that column for each county where the species is
present.<br>
Save the file (still as CSV).<br>
</font> <font face="Georgia"><br>
Open the county layer and the new CSV files in Ggis.<br>
Open the properties window for the county layer and click on the
Joins tab.<br>
Click on the "+" to add a new join. Join to the CSV layer, and
select the county names field as the join field for each.<br>
</font> <font face="Georgia"><br>
Now your county layer has the plant species column.<br>
To display a single species, open the properties window for the
county layer, select symbology. Set the symbology as rule based.
To color just those counties with species 1, your rule would say
something like Species1 = 1, where Species1 is the field name
you used. Pick a color/transparency of your choice, then set the
"all others" rules to be the background color you want.<br>
</font> <font face="Georgia"><br>
That does it for one species. You can then export to tiff or
whatever. Getting it to cycle through all the different species
is for someone else to explain.<br>
