We evaluated the effectiveness of habitat variables derived at two spatial scales for explaining the presence or absence of 20 bird species at 363 point count stations in an extensive industrial forest in Maine. Sixteen stand-level (microhabitat) and seven landscape-level (within 1 km radius, or 3.14 km2) variables were used in stepwise logistic regression models to evaluate the relative roles of these two spatial scales for explaining each species' occurrence at a point count station. Species were classified as either early-successional (n = 6) or late-successional (n = 14) species for analysis. Three regressions were run for each of the 20 species: (1) stand variable only, (2) landscape variable only, and (3) stand and landscape variables combined. Regression models that included only stand-level variables averaged significantly higher model concordance scores than regression models that included only landscape variables. For 17 of 20 species, regressions that included only stand-level variables better explained the presence or absence of a species at a point than did regression that included only landscape-level variables. The presence of two species was better explained by landscape variables, and the presence of one species could not be explained by either stand- or landscape-level variables. Because many variables were positively associated with presence of some species and negatively associated with other species, management for particular stand- or landscape-level features must be preceded by a determination of which species are more important to conserve.

- Synthesis of the conservation value of the early-successional stage in forests of eastern North America (2014, background): “In general, habitat structure is considered the most important habitat feature influencing suitability for birds (Niemi and Hanowski, 1984; Hagan and Meehan, 2002) and shrubland species in particular (Schlossberg et al., 2010).”
- Effect of Forest Structure and Fragmentation on Site Occupancy of Bat Species in Missouri Ozark Forests (2006, background): “As with many other species, habitat suitability for bats may be influenced by various factors at multiple spatial scales (Balcom and Yahner 1996, Grindal and Brigham 1999, Hagan and Meehan 2002).”
- Effects of urbanization on butterfly species richness, guild structure, and rarity (2007, result): “This argument is consistent with that made by Hagan and Meehan (2002) for forest birds, where they found stand (local) characteristics were more important in explaining bird diversity within a forested landscape compared to the importance of landscape features when forest patches occurred in an…”
- Accuracy of resource selection functions across spatial scales (2006, methodology): “First, we compared accuracy of RSFs of three studies of passerine birds that included single- and multigrain models (multigrain was less and greater than the home range) in fragmented shrub (Bolger et al ., 1997) and forest habitats (Mitchell et al ., 2001; Hagan & Meehan, 2002).”
