Native ash species, including white ash (pictured), have been declining rapidly this century due to predation by the emerald ash borer. [1]Silvics of North America (1991), [2] [3] a forest inventory compiled and published by the United States Forest Service, includes many hardwood trees.
The first logging operations in the Smokies, which began in the 1880s, used splash dams or booms to float logs down rivers to lumber mills in nearby cities. Notable splash dam and boom operations included the English Lumber Company on Little River, the Taylor and Crate operations along Hazel Creek, and the ambitious operations of Alexander ...

Today there is very little intact habitat in this ecoregion, with a reduction of bottomland hardwood forests by 70–95%, and only 0.02 percent of the original oak savannas remain. [3] Although much of the area is forested, these forests tend to be highly fragmented and significantly altered by development, agriculture, and fire suppression.
In the narrow sense of the terms, wood, forest, forestry and timber/lumber industry appear to point to different sectors, in the industrialized, internationalized world, there is a tendency toward huge integrated businesses that cover the complete spectrum from silviculture and forestry in private primary or secondary forests or plantations via the logging process up to wood processing and ...

The felled trees were processed at sawmills and shipped to the mainland. [10] Cornelis Corneliszoon (or Krelis Lootjes) was a Dutch windmill owner from Uitgeest who invented the first wind-powered sawmill in 1593. This made the conversion of logs into planks thirty times faster than previous manually operated sawmills. [11] [12]
Hardwood from deciduous species, such as oak, normally shows annual growth rings, but these may be absent in some tropical hardwoods. [3] Hardwoods have a more complex structure than softwoods and are often much slower growing as a result. The dominant feature separating "hardwoods" from softwoods is the presence of pores, or vessels. [4]
