I live in Central Florida and the quail population has severly declined over the past several decades. It's mainly due to the population explosion we have experienced. The population of Orange County was under 60,000 back in the late 1950's. You could hunt and fish anywhere. I could ride a horse through downtown and not turn an eye. Today we have almost 2,000,000 permanent residents in Central Florida. Add to that the 30,000,000 (yes, 30 million!) visitors each year, cars, exhaust fumes, crankcase runoff, and it's a miracle that even humans can live here!
Recently the Florida Game and Fish Commission has been studying the bobwhite quail decline. They published a paper explaining that the quail population has declined by more that 5% per yer, consistently over the past 5 years. That has qualified it to be placed on the State's "Protected Species" list. They are taking input as what solutions can be considered. I don't know what that would do to quail hunting down here if they are place on some kind of protected list.
