I am so far out of
my depth here there is no measurement for it.
Thanks to all...

I appreciate you taking the time for writing such a detailed set of instructions.
However, it is quicker for me to do it manually.
If the process could be automated then of course it would be a different matter.
I am working only with the ferns - less than a hundred records.
The flower plants are over 2500.
Perhaps others are better understanding how you want to visualize the distributions, but what I get from your description is that if you have 100 (or 2500) species then you will have 100 (or 2500) maps, which sounds unwieldy to me.
This paper https://www.sciencedirect.com/science/article/pii/S1574954116300097 might have some interesting suggestions for you.
Taken as a database design question, the idea of having 100 columns to record the presence or absence of each species is not elegant. A more normalized approach would be to have your geometry table (geometry of counties and unique key, perhaps county name) and a separate table with multiple rows per county, one for each species present, along with the county unique key, and then a one-to-many table join between the two.
Of course this doesn't necessarily help with the business of visualizing the data...
