Southern Ga and most of Florida have a subspecies of whitetail deer named Seminole whitetails. Generally these deer are adapted to lower quality habitat such as pine flatwoods that have a lot of browse but none of it is very nutritious. A mature buck (3.5 plus) will weigh around 135 to 150 live weight. 1.5 year old bucks average about 100 pounds live. The nutrition level of the native vegetation is low because of the soil its growing on...mostly sandy soils that dont hold nutrients well. Seminole whitetails that have access to large agricultural areas or other sources of higher nutritional plants such as large amounts of fertilized browse will exhibit heavier weights and better antlers because of the better food sources, but for this to show up it takes a deer generation. Also, the females will be more productive and fawn survival will be better. In these south Ga/Florida agricultural areas there will be older bucks that reach 200 pounds live weight and very good antler growth. It's all based on the soils......good soils =good deer. Two counties north and west of where I live there is the occasional B&C buck and several that that too 200 live weight....but there are more ag fields there than forest. Here its nearly all pine plantations and cypress swamps....a few miles from state line.
The picture below is a 4.5 year old buck on my place a few days ago. I know he's 4.5 because I have pics of him since he was 1.5. He has a solid black tail so he's easy to identify in pictures. At first glance he could be mistaken for a 175 plus pound deer....but he is closer to 135 pounds. Our rut peak here is late October and by first of November he will weigh about 120 or less.
I've hunted deer in only 2 states...Georgia and north Missouri. Whew! Night and day difference. It takes some focus to realize what your looking at when your used to looking at a mature buck that weighs 135 and then seeing one that weighs 200 plus. Thank goodness for a good rangefinder or I would still be misjudging them midwest brutes. Took me some time to adjust to seeing big deer with what appeared to be average racks when they actually had large racks....but their body size made their racks seem smaller. Had this same problem when hunting the coastal islands on the Georgia coast. Average buck there weighs less than 100 pounds and that makes his rack look large....but it ain't so.
