“…This may simply reflect a modification of historical foraging behavior that favored snags, and as noted above, the use of snags for foraging by white-headed woodpeckers has been observed in other studies (Hanson and North, 2008). Deadwood is an important foraging substrate for other North American woodpeckers (Nappi et al, 2015) and it should not be surprising that it can be important for some populations of white-headed woodpecker, despite accounts suggesting the opposite (e.g., Garrett et al, 1996).…”

“…These associations, however, may differ according to the type of deadwood produced [14]. Indeed, the Black-Backed (Picoides arcticus Swainson; hereafter BBWO) and the American Three-Toed (Picoides dorsalis Baird; hereafter ATWO) woodpeckers prefer to forage on dying trees or recent snags rather than on strongly decayed ones [15][16][17]. As primary cavity nesters, woodpeckers also rely on snags to excavate cavities for nesting, and they are considered as a keystone species in boreal ecosystems [18].…”

Standing deadwood is an important attribute of old-growth boreal forests and it provides essential microhabitats for deadwood-associated species. In managed boreal forests, short rotations tend to limit the amount and diversity of standing deadwood. This study evaluates if the anthropogenic supply of deadwood attributes through tree girdling or by providing nest boxes may favor deadwood-associated species. We studied the short-term response of saproxylic beetles, foraging woodpeckers, and secondary cavity users to snag and cavity supply in 50 to 70-year-old black spruce stands. In spring 2015, we girdled 8000 black spruce according to two spatial distributions (uniform and clustered), and we also installed 450 nest boxes of six different sizes at three distances from the forest edge. Using trunk window traps, we captured significantly more beetles in sites with girdled trees than in control sites in both 2015 and 2016. We also recorded a trend of a greater abundance of beetles in clusters of girdled trees than within uniformly distributed girdled trees. Trypodendron lineatum (Oliver) dominated beetle assemblages, representing 88.5% of all species in 2015 and 74.6% in 2016. The number of beetles captured was 7× higher in 2015 than in 2016. In contrast, we observed greater amounts of woodpecker foraging marks in fall 2016 than in either fall 2015 or spring 2016. Woodpeckers foraged significantly more in clusters of girdled trees than within uniformly distributed girdled trees. Woodpeckers' foraging mark presence was positively associated with the proportion of recent cuts at 1 km around the study sites. Five Boreal Chickadee (Poecile hudsonicus Forster) pairs used nest boxes and occupied smaller box sizes that were located away from the forest edge. Our study showed that structural enrichment can be effective in rapidly attracting deadwood-associated species within managed forest stands.

“…The Black-backed Woodpecker (Picoides arcticus) rapidly colonizes recently burned coniferous forests where it nests and forages in dense stands of fire-killed trees (Nappi and Drapeau 2009, Saab et al 2009, Nappi et al 2015. This population dynamic is attributed to the dependence of Black-backed Woodpeckers on their primary prey, the larvae of wood-boring beetles (Villard and Benninger 1993, Murphy and Lehnhausen 1998, Tremblay et al 2016.…”

ABSTRACT. The Black-backed Woodpecker (Picoides arcticus) is a snag-associated species that colonizes and utilizes patches of burned forests typically within 10 years of fire. Previous research has indicated that salvage logging, the removal of dead and dying trees from burned forests, has a negative effect on nesting densities of Black-backed Woodpeckers. One strategy proposed to ameliorate the impacts of dead tree removal on Black-backed Woodpeckers is to retain patches, or islands, of dense snags within the salvage matrix, but this approach remains largely untested. Following the Angora fire of South Lake Tahoe, CA several snag islands were retained within the larger salvage prescription to conserve habitat for Black-backed Woodpeckers and other snag-associated species. In this observational study, we evaluate whether these snag islands were effective at maintaining Black-backed Woodpecker populations following logging operations that covered 45% of the burned area. We systematically searched the postfire landscape for Black-backed Woodpecker nests for two years before and after salvage operations and compared nesting densities between logged and unlogged areas. Similar to other studies, we found that nest densities at the stand scale declined significantly in areas that were salvage logged, but Black-backed Woodpeckers did nest in both snag islands and in other peripheral unlogged areas, indicating that this approach may help balance habitat for wildlife with management needs at the scale of the fire. In this study, the removal of dead trees, which is usually implemented in the first two years following fire, did not occur until the fourth year, which may have also contributed to the persistence of Black-backed Woodpeckers postlogging.Persistance du Pic à dos noir après une coupe de récupération différée dans la Sierra Nevada RÉSUMÉ. Le Pic à dos noir (Picoides arcticus), une espèce associée aux chicots, colonise et utilise des îlots de forêts brûlées, généralement dans la décennie suivant un feu. Des recherches antérieures ont montré que la coupe de récupération, qui enlève les arbres morts et mourants des forêts brûlées, avait des effets négatifs sur la densité de Pics à dos noir nicheurs. Une des stratégies proposées pour réduire les impacts de l'enlèvement des arbres morts sur les pics est de conserver des îlots denses de chicots dans la matrice de récupération, mais cette approche n'a pas encore vraiment été testée. À la suite du feu Angora à South Lake Tahoe, en Californie, plusieurs îlots de chicots ont été conservés dans le cadre de la prescription de récupération, afin de conserver de l'habitat pour les Pics à dis noir et les autres espèces associées avec les chicots. Dans la présente étude observationnelle, nous avons évalué si ces îlots de chicots remplissaient leur fonction de maintenir les populations de Pics à dos noir à la suite des opérations de récolte de bois qui ont couvert 45 % de l'aire brûlée. À même le paysage brûlé, nous avons systématiquement cherché des nids de ce pic, 2 ans avant e...
