“…According to Martin et al [111], bird species richness did not decline in stands having up to 60% pine mortality but showed a strong negative impact when mortality exceeded 75% [113]. Drever et al [114], however, reported that the percent of red-attacked pines positively correlated to species richness of woodpeckers and negatively correlated to richness of other forest birds. In another study, Walters et al [115] found that the abundance of tree sap eater migratory northern flickers (Colaptes auratus L.) and red-naped sapsuckers (Sphyrapicus nuchalis B.)…”

Abstract:The mountain pine beetle (Dendroctonus ponderosae Hopkins) (MPB) has infested and killed millions of hectares of lodgepole pine (Pinus contorta var. latifolia Engelm) forests in British Columbia, Canada, over the past decade. It is now spreading out of its native range into the Canadian boreal forest, with unknown social, economic and ecological consequences. This review explores the ramifications of the MPB epidemic with respect to mid-term timber supply, forest growth, structure and composition, vegetation diversity, forest fire, climate change, and ecosystem resilience. Research confirms that, in British Columbia, all of these variables are more significantly impacted when salvage logging is used as management response to the outbreak. We conclude that appropriate management in response to MPB is essential to ensuring ecologically resilient future forests and reliable mid-term timber supplies for affected human communities. We highlight knowledge gaps and avenues for research to advance our understanding in support of sustainable post-disturbance forest management policies in British Columbia and elsewhere.

“…These guilds were: large-tree users, understory users, vertical-profile generalists, and shrub users. Further, we followed Altamirano (2014) to classify species into cavity-nesting and noncavity-nesting species, as the former guild is known to be sensitive to logging (Drever et al 2008). For continuous functional traits, we followed Julliard et al (2006) to quantify the degree of habitat-specialization for a species (SSI) as the coefficient of variation (standard deviation/average) of its estimated densities across the six habitat types described previously.…”

“…These four excavators produce cavities that are subsequently used by several secondary cavity nesters, including owls, parakeets, swallows, rayaditos, ducks, and small mammals (Altamirano 2014). Therefore, the validated-surrogate S. rufipes and cavityexcavator species rely on old-living and dead trees, and the latter group of birds positively influences the richness of other forest vertebrates (Drever et al 2008).…”

“…Some forest structural attributes increase stand-level complexity (McElhinny et al 2005), providing the necessary conditions for wildlife in general. Therefore, stand-level structural complexity may be the driver of a positive association between the surrogate candidate and target biodiversity (Drever et al 2008, Lindenmayer et al 2014a). Furthermore, it can expected that not all members of the top predator guild will be reliable surrogates because those that are habitatgeneralists may be able to adapt to degraded habitats (Ozaki et al 2006, Rodríguez-Estrella et al 2008.…”

Abstract. Using surrogate species to monitor the status of target biodiversity in areas undergoing exceptional habitat loss requires extending the traditional assessment of surrogates for taxonomic diversity to validating surrogates for functional diversity. This validation will be critical to inform about broader ecosystem processes and stability. We compared the surrogacy reliability of the habitat-specialist Rufouslegged Owl (Strix rufipes) and the habitat-generalist Austral Pygmy-Owl (Glaucidium nana), and we examined potential underlying mechanisms for surrogacy relationships in Andean temperate forests, a global biodiversity hotspot in southern Chile. During 2011-2013, we conducted 1,145 owl surveys, 505 vegetation surveys, and 505 avian point-transect surveys across 101 sites comprising a range of conditions from degraded forest habitat to structurally complex old-growth forest stands. The habitat-specialist S. rufipes was a reliable surrogate for all avian biodiversity measures, including avian endemism and functional diversity measures (degree of community specialization and density of large-tree users, understory users, and cavity-nesters). On the contrary, the habitat-generalist G. nana did not function as a surrogate. With increasing occurrence of S. rufipes, the density of target specialized biodiversity (species, guilds, and communities) increased nonlinearly and peaked at the least degraded sites. This specialist aggregation might be driven by stand structural complexity available in older, more stable, forests. These results suggest that management actions tailored to promote occurrence of habitat-specialist owls, such as the S. rufipes, may result in enhanced density of endemic species, specialized communities, and likely ecosystem stability.

“…Este mismo hecho hace que también sea considerada como una especie "carismática" o "emblemática", atrayendo la atención y admiración del público, por ende, se puede usar como especie central en actividades de educación ambiental o ecoturismo (Walpole y Leader-William 2002). Se le considera además una especie "clave", porque al hacer excavaciones en los árboles, ya sea para alimentarse, dormir o anidar, crea hábitats favorables para otras especies que usan cavidades secundarias (Ojeda 2004, Drever et al 2008.…”

SUMMARYIn this study we described the feeding habitat of the Magellanic woodpecker (Campephilus magellanicus) across forest ecosystems at Nahuelbuta National Park (37º 48´S y 72º 59´W), La Araucanía region, Chile. The study aims at filling the gaps on base line and scientific information needed for the elaboration of native forest management schemes oriented to the protection of wild fauna. Environmental and vegetation attributes related to the presence of C. magellanicus were identified in two samples applied: October 2008 and March 2009. Fifty count spots with three replications in each were sampled. We estimated population attributes of the bird assemblage from which C. magellanicus is an integral part. We identified 30 bird species and 4 forest types associated with the habitat of C. magellanicus. The forest types are combinations of Chilean birch species as "coigüe" (Nothofagus dombeyi), "lenga" (N. pumilio) and ñirre (N. antarctica), and monkey puzzle tree "araucaria" (Araucaria araucana). The forest types are "coigüe-araucaria", "coigüe-araucaria-lenga", and "coigüe" and "ñirre". We found significant correlations between C. magellanicus and crown-cover of dominant trees in 2008 and 2009, herbaceous-cover in 2009 and a very significant correlation with the decay degree of standing trees and herbaceous-cover in 2008. We concluded that the three most correlated attributes with the presence of C. magellanicus on the study area were the crown-cover of dominant trees, herbaceous-cover and the decay degree of standing trees.
