Forest vegetation covers an area of slightly over 6 million acres 

 or 9,450 square miles. Forests cover 68 percent of the tidewater counties 

 of Maryland, 60 percent of Virginia, and 48 percent of Delaware. The 

 forests of the tidewater counties of Chesapeake Bay are Oak-Hickory-Pine 

 as the major type, but also include Oak-Hickory, Oak-Pine, Loblolly-Shortleaf 

 Pine, and Oak-Gum-Cypress in the southern part. In many areas with better 

 soils there are a large number of mixed mesophytic deciduous species such 

 as maple, tulip tree, beech, gum, various oaks, and floodplain species of 

 ash, elm, maple, sycamore, and birch. The main timber trees are red and 

 white oaks; tulip tree, pines, sweetgum and, at times, other hardwoods.
