Many years ago the importation laws were lax. I was the Town Engineer shared by all the towns in the county. A farmer in my county got several of the tiny German deer and kept them in a several acre enclosure. They were very cute little things. A hurricane in the mid 80s knocked down a section of fence and part of the herd got out.
A few years later, my neighbor came over and asked if I had seen any tiny deer in the woods. Jim was used to seeing tiny deer when he was stationed in Germany. I laughed and told him where he had seen them(about 20 miles from where we lived). He asked how I knew and I explained.
Coyotes moved into the area and the tiny deer disappeared. There are plenty of white tails and if you look up when you walk in the woods every so often you will see a deer carcass up in a tree. We now have pumas.
One of the joys of nature is the surprises. You never know what you will find. Keep your eyes open and Good Luck, Rick
