Before moving away from the edge of paradise, in my opinion, I noticed good (equal to past) rabbit population, much lower squirrel, lower Hungarian Partridge (near non-existent) from even 30 years prior, and fair (fluctuating equal) fox, coyote, coon, and skunk, with a rise in the population of possum. The drainage of the wetlands through the Mississippi Flyway have really harmed the duck population in that region. Geese handle it better, but not the ducks. Other wetland animals, muskrat, beaver, weasel, and mink are down quit a bit. Badgers and woodchucks are suffering with slightly lower numbers as well.
As I typed the above I realized how much things have changed over the past few decades. What really makes this sad is that with all the programs, CRP and RIM, the numbers should be up and the health thriving.
