The Appalachian Mountains’ forested region is huge: the Appalachians span about 2,000 miles and cover about 198 million acres, with much of that landscape still forested. One Appalachian–Blue Ridge forest ecoregion is estimated at about 61,500 square miles, which is roughly 39.4 million acres.

Quick Scoop

  • The broader Appalachian mountain chain runs from Alabama to the Canadian Maritimes and forms a nearly continuous forested landscape.
  • Forest types vary by elevation and latitude: spruce-fir is more common in the north and high elevations, while mixed broadleaf forests dominate farther south and lower down.
  • So if you mean “how big is the forested Appalachian region,” a practical answer is: massive , stretching across multiple states and totaling tens of millions of acres.

In plain terms

If you picture the Appalachians as a long green corridor, that’s pretty close. The forests are not one single block, but a vast connected region of mountains, valleys, wetlands, and rivers. In many places, trees cover most slopes and ridges, which is why the range is often described as deeply forested.

Measure Approximate size
Appalachian region 198 million acres
Appalachian–Blue Ridge forests ecoregion 61,500 square miles / about 39.4 million acres
Appalachian Highlands forest province 68,100 square miles / about 43.6 million acres

TL;DR

The forested Appalachians are enormous: think a 2,000-mile mountain chain with tens of millions of forested acres, not just a few wooded hills.
