“…Hansen et al (1995b) using bird abundance data from several studies in the U.S. Pacific Northwest, suggested that most forest birds can be placed in four guilds in terms of overstory tree canopy density: open canopy species (e.g., Dark-eyed Junco and American Robin); open canopy with dispersed large trees (e.g., MacGillivray7s Warbler, Hammond's Flycatcher, and Western Tanager); structurally complex closed-canopy (e.g., Brown Creeper, Chestnut-backed Chickadee and Winter Wren); and structurally simple closedcanopy species (e.g., Golden-crowned Kinglet and Swainson's Thrush). Our results, and those of Mannan and Meslow (1984), Adam et al (1996), andHagar et al (1996) in the northwestern U.S.A., and Annand and Thompson (1997) in hardwood forests of Missouri, supported that conceptualization. By varying the intensity and spatial pattern (dispersed or clumped) of timber harvest within a stand, forest managers can create the range of conditions favoured by the different guilds.…”

“…Most abundant in large undisturbed tracts of contiguous forest, but will also use forests in late successional stages (Mannan and Meslow 1984, Kessler and Kogut 1985. In the Tanana Valley of interior Alaska, this species is largely restricted to mature white spruce forests where breeding density is positively related to the density and dominance of white spruce .…”

“…The availability of cavity trees is considered one of the most important factors to the success of populations of cavity-nesting birds and is of increasing concern because of removal of cavity trees and snags under intensive timber management (McClelland and Frissell 1975). Several studies revealed an adverse impact of timber management on cavity tree resources and thus on cavity-dependent birds and wildlife (Conner et al 1975;Cline et al 1980;McComb and Nobel 1980;Mannan and Meslow 1984;Zarnowitz and Manuwal 1985). Resource managers are often required to incorporate the habitat requirements of cavity-using wildlife into management plans and assess trade-offs between wildlife and timber resource goals (Loehle et al 2002).…”

Abstract:We used classification and regression tree analysis to determine the primary variables associated with the occurrence of cavity trees and the hierarchical structure among those variables. We applied that information to develop logistic models predicting cavity tree probability as a function of diameter, species group, and decay class. Inventories of cavity abundance in old-growth hardwood forests in Missouri, Illinois, and Indiana found that 8-11% of snags had at least one visible cavity (as visually detected from the ground; smallest opening ≥2 cm diameter), about twice the percentage for live trees. Five percent of live trees and snags had cavities on mature (≥110 years) second-growth plots on timberland in Missouri. Because snags accounted for typically no more than 10% of standing trees on any of these sites, 80-85% of cavity trees are living trees. Within the subset of mature and old-growth forests, the presence of cavities was strongly related to tree diameter. Classification and regression tree models indicated that 30 cm diameter at breast height (DBH) was a threshold size useful in distinguishing cavity trees from noncavity trees in the old-growth sample. There were two diameter thresholds in the mature second-growth sample: 18 and 44 cm DBH. Cavity tree probability differed by species group and increased with increasing decay class.Résumé : Nous avons utilisé la classification et l'analyse d'arbres de régression pour identifier les principales variables associées à l'occurrence d'arbres à cavité et la structure hiérarchique entre ces variables. Nous avons utilisé cette information pour développer des modèles de régression logistique visant à prédire la présence de cavités en fonction du diamètre, du groupe d'essences et de la classe de carie de l'arbre. Des inventaires d'abondance de cavités dans des forêts anciennes de feuillus au Missouri, en Illinois et en Indiana ont montré que 8-11 % des chicots ont au moins une cavité visible (détectée par examen visuel à partir du sol; diamètre de la plus petite ouverture ≥2 cm), soit le double du pourcentage correspondant pour les arbres vivants. Cinq pourcent des arbres vivants et des chicots avaient des cavités dans des placettes en forêt de seconde venue mature (≥110 ans) dans les régions boisées au Missouri. Étant donné que les chicots ne comptent typiquement pas pour plus de 10 % des arbres sur pied à chacun de ces sites, 80-85 % des arbres à cavités sont donc des arbres vivants. Si on prend en compte seulement les forêts matures et les forêts anciennes, la présence de cavités est fortement reliée au diamètre de l'arbre. Les modèles de classification et d'arbres de régression indiquent qu'un diamètre à hauteur de poitrine (DHP) de 30 cm constitue une taille seuil pour distinguer les arbres avec cavités de ceux sans cavités dans les forêts anciennes. Dans les forêts de seconde venue, il y a deux seuils : 18 et 44 cm DHP. La probabilité qu'un arbre ait une cavité varie selon les groupes d'essences et augmente avec la classe de carie.[Traduit par la ...
