    By which I mean the problems that arise when an exotic species is accidentally or imprudently introduced into an environment where it has no natural predators. Are there simply too few of these game animals or are their reproduction rates too low for this to be an issue?

    Also, isn't inbreeding going to become a problem on these ranches?

    •  No, that would be more like feral hogs here (5+ / 0-)

      Most of the exotics live on very large and high fenced ranches.  The ranch owners do not want their animals to escape because that's their money.  Some species do escape, but not in the numbers required to become an invasive species.  They generally have the same predator and hunting problems that the native white tail and mule deer have, so it keeps them in check.  

      Deer usually breed once a year, compared to wild hogs or rabbits which breed several times a year.

      objections to importing and wildlife. Exotics could bring disease or parasites that native species have no resistance to.

      Reproduction of large ungulates is generally not too fast. One per year per female.
