New Engl<strong>and</strong> Subregion (Focal Areas GL12–GL16; Figures 3–50 <strong>and</strong> 3–51, Table 3–15)<br />
General Description<br />
This subregion contains the St. Lawrence Valley,<br />
Lake Champlain, <strong>and</strong> Quebec <strong>and</strong> supports<br />
approximately 0.4% of the region’s <strong>and</strong> world’s<br />
<strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s. The primary habitats<br />
for <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s in these areas are<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 />
3–79<br />
upl<strong>and</strong> shrubs, shrub wetl<strong>and</strong>s, <strong>and</strong> successional<br />
forest. Major threats to the small populations<br />
found here are succession, conversion to<br />
agricultural l<strong>and</strong> use, <strong>and</strong> Blue-<strong>winged</strong> <strong>Warbler</strong><br />
encroachment.<br />
• The following types of primary l<strong>and</strong> cover: 10% herbaceous cover, 15–40% shrub cover, <strong>and</strong> 58%<br />
forest cover with the latter comprised of trees that are 16–33 ft (5–10 m) tall (5%), 33–82 ft (10–<br />
25 m) tall (60%), <strong>and</strong> 82–160 ft (25–50 m) tall (10%).<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 contain:<br />
• The following primary l<strong>and</strong> cover types: deciduous forest (44%); pasture/hay (8%); woody<br />
wetl<strong>and</strong>s (9%). More <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s were associated with woody <strong>and</strong> emergent<br />
wetl<strong>and</strong>s, shrub-scrub <strong>and</strong> grassl<strong>and</strong>-herbaceous meadows than Blue-<strong>winged</strong> <strong>Warbler</strong>s. More<br />
Blue-<strong>winged</strong> <strong>Warbler</strong>s are associated with pasture-hay, cultivated cropl<strong>and</strong>, <strong>and</strong> coniferous <strong>and</strong><br />
mixed forests than <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s.<br />
