Most ofthe upper two-thirds of the subbasin is forestedand typical of the western hemlock vegetationzone; timber harvest is the predominant land use,with about three-fourths of the subbasin withinthe region in tree cover or regenerating forests.A 30-square mile area was denuded by the 1980eruption of Mt. St. Helens, and forestry and fireresult in patchy disturbances over time. Much ofthe lower subbasin is pasture and grassland, withrural and urban development. Urban developmentis primarily concentrated in Amboy andWoodland in the North Fork, and around BattleGround, La Center, Ridgefield, Yacolt, and the I-5corridor in the East Fork. The urban populationin the subbasin is expected to increase significantlyin coming decades.Historically, the Lewis River subbasin wascovered almost entirely by coniferous forest(54 percent) and burned forest (40 percent), withonly 2 percent prairie and 1 percent oak. It wasthe second most heavily forested basin in thegreater Portland-Vancouver region and remainsso today. Almost all prairie and oak and about20,000 acres of conifer forest and burned forestwere converted to agriculture, which covers about13 percent of the subbasin. Only 2 percent of thesubbasin is in urban cover (La Center and part ofWoodland). An increase of more than 3,900 acresof water in the subbasin is attributable to theSkamania counties.
