Breeding <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s require a complex structure of habitat components that occur within<br />
a variety of ephemeral, young forest, <strong>and</strong> other ESHs that result from disturbances, like timber<br />
harvesting (Figure 3–4) or fire, <strong>and</strong> more permanent ecological conditions, such as alder swamps <strong>and</strong><br />
oak barrens. Regardless of the habitat’s origin or degree of permanency, the basic conditions required<br />
by <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s are approximately the same:<br />
Shrubby, young forest with limited canopy cover that is frequently interspersed with<br />
herbaceous areas of grasses <strong>and</strong> forbs, <strong>and</strong> includes widely spaced overstory trees for<br />
song perches (Figures 3–4 <strong>and</strong> 3–5). This basic patch-level configuration often borders<br />
more mature forest <strong>and</strong> is usually set within a l<strong>and</strong>scape matrix of deciduous forest.<br />
Figure 3–4. This newly harvested aspen forest has a moderate density of residual canopy trees with a high<br />
proportion that are hardwoods (northern red oaks) dispersed throughout the st<strong>and</strong>. In a couple of years, when the<br />
understory has regrown, this site should provide excellent nesting habitat for <strong>Golden</strong>-<strong>winged</strong> <strong>Warbler</strong>s. Photo by<br />

We highly recommend working within the pre-defined focal areas for your region <strong>and</strong> in places with<br />
limited co-occurrence of Blue-<strong>winged</strong> <strong>Warbler</strong> (Figures 3–6 to 3–10). See Part II (page 3–46) for maps<br />
<strong>and</strong> detailed descriptions of each focal area.<br />
We use four guiding principles to describe habitat associations <strong>and</strong> provide management guidelines:<br />
1. Context—what is the l<strong>and</strong>scape-scale context of the management site?<br />
2. Configuration—how are the major habitat components configured at the scales of the<br />
management site <strong>and</strong> patch?<br />
3. Content—what are the major habitat components within a patch or st<strong>and</strong>?<br />
4. Composition—what are the key species or plant community associations within the region <strong>and</strong><br />
habitat type?<br />
Context is discussed at the l<strong>and</strong>scape scale, while Configuration, Content, <strong>and</strong> Composition are<br />
considered at the scales of the management site <strong>and</strong> patch or st<strong>and</strong>.<br />
