Mike,
As the Everglades I was prety much including all "natural" areas below lake O that is also about the limit of berms living sucessfuly for the long run.
The question of ssp. is a complicated one mainly because most ssp's have been determined by visual caracteristics and how much they are different genticaly may be little or none. Most animals that are geographicly isolated for even a few hundred years with no "new blood" added will change enough to look or be new ssp. I have often thought if a scientist who had never seen or heard of a dog was doing the taxonomy of them hew many sp and ssp would they come up with. Because we know the history of them we we say they are all the same. The iguanas on the islands in the sea of cortez are believed to be released by indians long ago from the mainland but have enough physical differences now to be a different ssp. Think about if I took a banana cal king back in time 200 years and let it go on catalina island today we would probobly consider it a new sp visualy after only 30 years of selective breeding.
Just a few thought about the whole ssp thing.
If you want to include ssp to make it easy just include animals that would be affected by bermese pythons since that is the main focus of the topic and seperate sp from ssp
