Priority bird species associated with forest-woodland habitat include
the Cerulean Warbler, Worm-eating Warbler, Kentucky Warbler, Whip-poor-will,
and Wood Thrush.
Large expanses of relatively intact hardwood forest are among
the Central Hardwoods’ greatest ecological assets. They suppress
populations of nest and brood predators and the brood parasite,
the Brown-headed Cowbird. Reproductive success tends to be relatively
high in these forested landscapes. Offspring of forest birds breeding
in the CHBCR may colonize more fragmented forests of the Midwest
where reproductive success is too low to sustain local populations.
Today, forested landscapes are threatened by fire suppression and
urbanization. Conversion to campgrounds and pasture has been especially
prevalent in bottomland forests along rivers.

Vast
expanses of native short-leaf pine woodlands were present in the
CHBCR prior to the logging boom of the early 20th century and once
supported birds that are now of national importance such as the
Red-cockaded Woodpecker (an endangered species), Brown-headed Nuthatch,
and Bachman’s Sparrow. Although short-leaf pine
can still be found in mixed forest stands in the Ozarks, both fire
suppression and widespread logging led to the demise of the pine
ecosystem in the CHBCR. As a result, the Red-cockaded Woodpecker
has been extirpated, and the Brown-headed Nuthatch nearly so, with
only a small population remaining in Arkansas.
Restoration of native pine woodlands is now underway
in several areas in the Ozark region, with the most notable being
the 10,000-acre Pine
Knot project on the Mark Twain National Forest. |
