Southern Appalachian-Cumberl<strong>and</strong> Subregion (Focal Areas A12–A14; Figures 3–35 <strong>and</strong> 3–36;<br />
Table 3–8)<br />
General Description<br />
This subregion supports approximately 3% of the<br />
region’s (<strong>and</strong> 0.1% of the world’s) <strong>Golden</strong>-<strong>winged</strong><br />
<strong>Warbler</strong>s. The areas are characterized by small<br />
but often high-density local populations primarily<br />
on reclaimed surface mine sites. Significant<br />
management opportunities exist with forest<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 />
3–57<br />
management but require additional post-harvest<br />
treatments of prescribed burning <strong>and</strong> use of<br />
herbicides to control woody growth. Major<br />
threats in these areas are succession <strong>and</strong> the remining<br />
of previously-mined <strong>and</strong> ab<strong>and</strong>oned<br />
surface mines.<br />
• Elevations ranging from 1975–3000 ft (600–800 m) but habitat management to exclude Blue<strong>winged</strong><br />
<strong>Warbler</strong>s should be above 2000 ft (620 m).<br />
• A high proportion of contiguous forest (100% forest cover) which is unique to the southern<br />
Appalachians. In contrast, around 25% of <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s are found in l<strong>and</strong>scapes<br />
where herbaceous cover is between 70–90%.<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 (48%), grassl<strong>and</strong>-herbaceous<br />
cover (14%), <strong>and</strong> barren cover (8%). Barren cover is uniquely important in this subregion <strong>and</strong><br />
may include glacial debris, surface mines, <strong>and</strong> gravel pits. Also the absence of wetl<strong>and</strong> cover<br />
types is a notable difference for <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong> sites in this subregion as compared to<br />
elsewhere in the range.<br />
