Central Appalachian Subregion (Focal Areas A9–A11; Figures 3–33 <strong>and</strong> 3–34; Table 3–7)<br />

General Description<br />

The focal areas in this subregion support<br />

approximately 21% of the region’s (<strong>and</strong> 1% of the<br />

world’s) <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s. The primary<br />

habitats for <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s in these<br />

areas are ab<strong>and</strong>oned contour mines <strong>and</strong><br />

pasturel<strong>and</strong>s in West Virginia, <strong>and</strong> ab<strong>and</strong>oned<br />

farml<strong>and</strong> <strong>and</strong> pasturel<strong>and</strong>s in Virginia. There is<br />

ample opportunity in this subregion to create<br />

Macro L<strong>and</strong>scape Context (within 1.5 mi (2.5 km) of management site)<br />

<strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s are generally associated with l<strong>and</strong>scapes containing:<br />

3–54<br />

<strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong> habitat through forest<br />

management, management of pasturel<strong>and</strong>s, <strong>and</strong><br />

reforestation of minel<strong>and</strong>s. Major threats in<br />

these areas are restricted access for monitoring,<br />

lack of timber management to create new<br />

habitat, Blue-<strong>winged</strong> <strong>Warbler</strong> encroachment, <strong>and</strong><br />

succession <strong>and</strong> mountaintop mining of contour<br />

mines.<br />

• Elevations ranging from 1975–2650 ft (600–800 m) but habitat management to exclude Blue<strong>winged</strong><br />

<strong>Warbler</strong>s should be above 2035 ft (620 m).<br />

• A higher ratio of deciduous trees in the l<strong>and</strong>scape (90:10; deciduous:coniferous trees) than in<br />

the rest of the region.<br />

• Forests that are 33–82 ft (10–25 m) in height (i.e. large sapling to small sawtimber sized trees).<br />

• Sugar maple-beech-yellow birch <strong>and</strong> yellow poplar (sometimes with red oak) forests.<br />

Micro L<strong>and</strong>scape Context (within 0.15 mi (0.25 km) of management site)<br />

Sites where <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s are found generally:<br />

• Contain the following primary l<strong>and</strong> cover types: deciduous forest (47%); pasture/hay (8%); <strong>and</strong><br />

grassl<strong>and</strong>/herbaceous (4%). Very few <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s are in emergent wetl<strong>and</strong>s <strong>and</strong><br />

none are in woody wetl<strong>and</strong>s. Blue-<strong>winged</strong> <strong>Warbler</strong> are more frequently associated grassl<strong>and</strong>herbaceous<br />

<strong>and</strong> evergreen <strong>and</strong> mixed forests <strong>and</strong> less in pasture-hay.<br />
