I totally agree that breeding also needs to be worked in concert to habitat reconstruction (as is being done with our New Jersey Pine Snake). You should also take into account the lessening of pollution in some areas (believe it or not some places are actually becoming cleaner). Also, the decline of snake populations, in the simplest mathematical sense, means that less snakes are going to meet and reproduce. What is the harm in assisting this otherwise natural action?

You've never had to play "wingman" before?
