工业伐木已成为中非最广泛的土地利用方式，目前特许经营的森林面积超过60万平方公里（30%）。利用1976年至2003年期间的卫星图像时间序列，我们测量了51，916公里的新伐木道路。穿越森林地区的道路密度为每平方公里0.03公里，但加蓬和赤道几内亚的道路密度超过每平方公里0.09公里。在刚果民主共和国境内发现了一个新的伐木扩张前沿，该地区剩余森林的63%位于该国境内。树木砍伐和防滑痕迹增加干扰选择性采伐区。
Industrial logging has become the most extensive land use in Central Africa, with more than 600,000 square kilometers (30%) of forest currently under concession. With use of a time series of satellite imagery for the period from 1976 to 2003, we measured 51,916 kilometers of new logging roads. The density of roads across the forested region was 0.03 kilometer per square kilometer, but areas of Gabon and Equatorial Guinea had values over 0.09 kilometer per square kilometer. A new frontier of logging expansion was identified within the Democratic Republic of Congo, which contains 63% of the remaining forest of the region. Tree felling and skid trails increased disturbance in selectively logged areas.
