Great Lakes Region<br />
Most common habitat types used:<br />
• Forest or shrub wetl<strong>and</strong>s (alder/willow wetl<strong>and</strong>s, beaver wetl<strong>and</strong>)<br />
• Aspen clearcuts<br />
• Successional forest (regenerating young forest from forest management or other disturbance)<br />
• Tamarack bog<br />
• Upl<strong>and</strong> shrub communities (ab<strong>and</strong>oned farml<strong>and</strong>, shrubby fields)<br />
Configuration within Management Sites:<br />
• Patches of young forest or other ESH with feathered edges (see sidebar, page 3–15) leading up<br />
to mature forest boundary.<br />
• Patches < 1000 ft (300 m) from existing, suitable habitat should be > 5 ac (2 ha), while those ><br />
1000 ft (300 m) from existing habitat should be > 25 ac (10 ha).<br />
• Within large management complexes, at any given time, 15–20% of area should be maintained<br />
in early successional or young forest habitat.<br />
Content within Patches:<br />
• Overstory trees (> 9 in or > 23 cm dbh), saplings, shrubs, herbaceous openings, bare ground, <strong>and</strong><br />
sometimes surface water<br />
Configuration within Patches:<br />
• Tall shrubs <strong>and</strong> saplings 3–13 ft (1–4 m) unevenly distributed as clumps (see sidebar, page 3–15)<br />
should make up 30–70% of patch.<br />
• Shrub <strong>and</strong> sapling clumps should be interspersed with herbaceous openings that are primarily<br />
composed of forbs with lesser proportions of grasses.<br />
• Low woody vegetation (< 3 ft (1 m)), leaf litter, <strong>and</strong> bare ground can occur in openings but<br />
should occupy less than 25% of opening’s space.<br />
• Overstory trees should be infrequent (5–8/ac (10–15/ha)) <strong>and</strong> widely spaced (or clustered),<br />
resulting in 10–30% canopy cover. At least 50% of overstory trees should be deciduous.<br />
• Average distance to microedge (see sidebar, page 3–15) should be less than 20 ft (6 m) from any<br />
point within the patch.<br />
