Northern Appalachian Subregion (Focal Area A8; Figures 3–31 <strong>and</strong> 3–32; Table 3–6)<br />

General Description<br />

This subregion supports approximately 27% of<br />

the region’s (<strong>and</strong> 1% of the world’s) <strong>Golden</strong><strong>winged</strong><br />

<strong>Warbler</strong>s. The primary habitats in this<br />

area are managed successional forest,<br />

ab<strong>and</strong>oned farml<strong>and</strong>, scrub barrens, utility rightsof-way,<br />

<strong>and</strong> reclaimed surface mines. Major<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 />

3–51<br />

threats in this area are lack of active timber<br />

harvesting, energy extraction, <strong>and</strong> Blue-<strong>winged</strong><br />

<strong>Warbler</strong> encroachment. With appropriate sitescale<br />

reclamation, energy extraction may also<br />

create additional <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong> habitat.<br />

• Elevations ranging from 1200–2300 ft (370–700 m) but habitat management to exclude Blue<strong>winged</strong><br />

<strong>Warbler</strong>s should be above 1575 ft (480 m).<br />

• 60–95% forest cover that is widely dispersed <strong>and</strong> more open than in the southern Appalachians.<br />

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

• The following l<strong>and</strong> cover types: mixed deciduous-coniferous forests <strong>and</strong> open woodl<strong>and</strong>s (e.g.<br />

savannah, pine <strong>and</strong> oak barrens, forest-grassl<strong>and</strong> ecotones). Some <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s are<br />

associated with upl<strong>and</strong> red maple forests, an association not found elsewhere in the region.<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 />

• Have a slightly higher herbaceous cover (mean of 45%) than region-wide (mean of 40%).<br />

• Have a lower ratio of deciduous:coniferous trees (85:15) relative to farther south.<br />

• Contain the following primary l<strong>and</strong> cover types: deciduous forest (46%); pasture-hay (12%); <strong>and</strong><br />

evergreen <strong>and</strong> mixed forests (6%). Very few <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s are associated with shrubscrub<br />

or wetl<strong>and</strong> habitats at this scale. Compared to <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s, Blue-<strong>winged</strong><br />

<strong>Warbler</strong>s were more frequently associated with urban l<strong>and</strong>scapes (11%, compared with 3% for<br />

<strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>).<br />
