Very grateful that this thread wasn't locked.... The only additionl to add is that the pythons were in place and breeding before anyone noticed. I'm very worried that like a few islands in the Pacific where snakes were introduced... the pythons have the ability over time to dramatically change the nature of the Park's biology... (the islands I'm talking about lost their entire bird populations after snakes were accidentally introduced). The only road into the Park is exactly 38 miles long (compared to the roughly 90 by 90 miles the Park covers) so we have a very, very limited access to it unless you're in a boat. So far I haven't seen or heard that they're spreading rapidly towards the west - all the new sightings have been back towards the east and down into the upper Keys. Eastern Diamondback rattlers, cottonmouths.... yes, we have plenty but they don't concern me at all. The pythons with their appetites and ability to breed in great numbers... they worry me a lot.
