Think you're not seeing enough deer in your area? Whitetail populations in some areas of northern Maine are estimated at 1-4 deer per square mile. Given the dense forests of this region, the odds of seeing deer -- much less tagging a trophy buck -- are slim indeed. Maine's annual whitetail harvest, which peaked at 28,000 animals in the late 1980s, has dropped to under 20,000 recently. Statewide population estimates place the herd at some 250,000 animals.
