I read somewhere that the cold from the past winter has killed about half of them, mostly larger ones. It also disrupted the breeding cycle, according to the article. Another article I read shows the brums breeding with the rocks, they create a super python! I believe that article to be propaganda though. They have only found like 5 rocks in Florida. And even if they dont get a big as they do in captive a 8-12 foot snake is still a big snake no matter what you say. To the public that 8 footer is like a green anaconda! lol
