My cousins have a charter fishing buisness in islamorada in the keys and i do alot of fishing down there and i was down there in 2010 during those frosts. I can tell ya from my experience it was bad for the entire region. We saw dead schools of bait fish inland which is real bad cause fish have the range to find warmer waters so if it affected fish then its obvious it affected land based reptiles. The thing about these surveys is they can write whatever they want and people believe it if it comes from a credible source. How do we really know what the truth is? There is no way the pythons in the glades were killing the numbers of animals they are saying. Here in virginia when the dgif does herd surveys on deer in different regions its all done on speculation. There is no way they can know how many animals are in a certain region. Therefore theres no way to know how many animals the snakes are eating in the glades. Are they catching these snakes and cutting em open? No. Are they observing the snakes eating? No. Do they even have an idea how many pythons are there? Absolutely not. What they are doing is finding some pythons in a block of land of say 2 miles square. Then they say for every 2 mile block thetes this many pythons for the entire region. Its all pure speculation at its best. Speculators always ruin everything.
