Quick Start Guide for L<strong>and</strong> Managers<br />

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 />
