The Decline of Bottomland Hardwood Forests of the Lower Mississippi River

The Loss of the Ivory-Bill's Natural Habitat in the Big Woods of Arkansas

The decline of the ivory-billed woodpecker is a story of habitat loss.

The ivory-billed woodpecker once ranged from Texas to North Carolina, from southern Illinois through Florida and south to Cuba. It dwelled primarily among swampy bottomland hardwood forests, preferring wilderness and the deep cover of old-growth woods. These forests provided the bird with an endless supply of dead and dying trees, where the ivory-bill found its primary food source of beetle larvae living under the bark.

Before European settlement, some 52 million acres of the Southeast were a wilderness of bottomland hardwood forests — forests that develop in the floodplains of slow-moving rivers and streams. These forested wetlands have their tree roots in wet soil and their trunks often in standing water.

Nearly half of the Southeast’s bottomland hardwood forests were found in the Mississippi River Delta spanning seven states. Today these Delta forests have shrunk to less than one-fifth of their original 24 million-acre extent.

It is in these vastly diminished forests of the Delta that the ivory-billed woodpecker was rediscovered in Arkansas in 2004.
