“…Time available for breeding is, however, limited, especially in northern latitudes, and cavity-excavating species can save time by reusing old nest holes. Obviously, cavity-excavating bird species are likely to face a trade-off between excavating a new cavity and reusing an old one, and the decision depends on, e.g., population structure or different risks such as predation, competition and ectoparasitism (Short 1979, Aitken et al 2002, Wiebe et al 2006, Mazgajski 2007a. The use of an old cavity may also be beneficial because woodpeckers have previously found it structurally sound, its location is advantageous for feeding or previous nesting attempts were successful (see Aitken & Martin 2004, Wiebe et al 2007).…”

Cavity-nesting birds can save time and energy by reusing old cavities. We studied cavity reuse and its connections to nesting success and timing in the three-toed woodpecker Picoides tridactylus in a 170-km 2 area in southern Finland during 1987-2015. The data include 520 nest trees, 645 nest cavities and 833 nestings in 86 territory sites, including 211 cases of cavity reuse. Twenty-five percent of nestings was in previously used cavities. Twenty-eight percent of cavities and 25% of nest trees were used more than once. Reuse improved nesting success and facilitated early nesting in the year following first nesting. Reuse of nest trees with several cavities was observed in 15% of nest trees, and 62% of reused cavities were in those multi-cavity trees. Cavity reuse and multi-cavity trees were most abundant in long-term territories with stable habitats. In boreal forests, cavity and tree reuse can be an important adaptation allowing efficient nesting during a short breeding season.

“…Early reports concentrated on the value of broadleaves to wildlife (Enns et al 1993) and the need to retain minor amounts of these species in future forests, particularly in riparian zones. With more research, the broader contribution of broadleaved species to biodiversity, forest health and ecosystem functioning has been increasingly recognized (Aitken et al 2002, Lindenmayer and Franklin 2002, Hagar 2007) and the need for a multi-scale approach to planning species retention along multiple management pathways has been proposed (Comeau et al 2005, Simard andVyse 2006).…”

“…broadleaves in mixed stands include limiting spread of root disease among conifers (Morrison et al 1988, Gerlach et al 1997, reducing the risk of conifer attack by weevils and spruce budworm (Taylor et al 1994, McIntosh et al 1996, protecting understory conifers against frost (Andersson 1985, Pritchard andComeau 2004), providing habitat for ungulates, small mammals and birds (Peterson et al 1997, Aitken et al 2002, and improving soil productivity through nutrient-rich litter inputs (Brockley and Sanborn 2003). In keeping with this last point, total yield (conifers plus broadleaves) in mixed forests has sometimes been higher than in pure coniferous forests because of niche complementarity (Kenk 1992, Mielikainen 1996, Frivold and Kolström 1999, Man and Lieffers 1999, Valkonen and Valsta 2001.…”

The principal broadleaves in Interior British Columbia (trembling aspen, paper birch, balsam poplar and black cottonwood) are well distributed across all of the major Interior ecological zones but their occurrence is greatest in the northern areas. Their utilization has gradually increased over the last 20 years, especially in the north. Economic values are low compared to conifer species but shortage of conifer timber as a result of the mountain pine beetle epidemic could drive demand for broadleaves higher. The ecological and non-timber values of broadleaves are very high; however, management practices still favour conifer species. Retention of broadleaves in harvesting and reforestation programs is widely implemented, but at a very low intensity and with little attention to broadleaf silvics. Future management of broadleaves is likely to be based largely on natural regeneration of broadleaves and not nursery production. Investments in genetic research should focus on genecology and gene conservation, as well as facilitated migration studies and investigation of pest resistance.Key words: broadleaves, trembling aspen, paper birch, black cottonwood, balsam poplar, management, genetic conservation, genetic improvement RÉSUMÉLes principaux feuillus retrouvés dans la région intérieure de la Colombie-Britannique (le peuplier faux-tremble, le bouleau blanc, le peuplier baumier et le peuplier baumier de l'Ouest) ont une distribution uniforme dans toutes les zones écologiques les plus importantes de la région intérieure, mais leur présence est plus dominante dans le nord de la province. Leur utilisation s' est accrue de façon progressive au cours des 20 dernières années, surtout dans le nord. La valeur économique de ces bois est faible en comparaison avec les espèces résineuses, mais la pénurie de bois d' oeuvre de résineux découlant de l' épidémie du dendroctone du pin ponderosa pourrait faire progresser la demande de bois de feuillus. La valeur écologique et la valeur des produits autres que ceux liés au bois d' oeuvre de feuillus sont très élevées; cependant, les pratiques d'aménagement continuent de favoriser les espèces résineuses. La rétention des feuillus lors de la coupe et dans les programmes de reboisement est implantée de façon générale, mais à un faible niveau et avec peu d'attention à la sylviculture des feuillus. L'aménagement futur des feuillus reposera vraisemblablement sur la régénération naturelle des feuillus et non sur la production de semis en pépinière. Les investissements en matière de recherche génétique devraient être concentrés sur la génécologie et la conservation des caractéristiques génétiques, ainsi sur les études de migration et la recherche sur la résistance aux ravageurs.

“…A similar effect occurs in secondary forests, where the density of large cavities tends to decrease due to the smaller diameter of the trees (Willis & Oniki 2001, Cornelius et al 2008, Cockle et al 2011a). Further, timber management practices based on the exploitation of decaying trees have caused disastrous declines in cavity-nesting birds in Europe and North America (Dobkin et al 1995, Aitken et al 2002, Franco et al 2005. These are evidences that forest type, successional stage, and degree of human disturbance are key elements for cavity nests availability and for the persistence of cavity-nesting birds (Cornelius et al 2008).…”

Successional stage effect on the availability of tree cavities for cavity-nesting birds in an Atlantic Forest park from the state of São Paulo, Brazil

The availability of suitable cavities and substrate for hole construction can limit the populations of birds that rely on tree hollows to reproduce. Several studies have focused on the effects of types of habitats, and types of human disturbances on cavities abundance, but the effect of successional stages in the Atlantic Forest has been poorly addressed. In this study we aimed to compare the availability and biometric characteristics of tree cavities between primary and mid-successional stage sites in an Atlantic Forest area from southeastern Brazil. Based on nest characteristics described in the literature, we inferred if hollows present in secondary sites could harbor the large secondary-nester Atlantic Forest birds, with special attention to toucans and hawks. From September 2016 to April 2017, 96 cavities were sampled, 67 in the primary, and 29 in the secondary plots. Our data revealed that the communities of cavity-nester birds in mid-successional stage areas may be more affected by the reduced cavity availability than by cavities quality, as the number of cavities in these sites was less than half than that found in mature forests. We also provide evidences that the largest cavity nesters, such as the biggest hawks, might have limited nesting possibilities in mid-successional stage areas especially due to small cavity entrances, which may have important reflects in conservation strategies.
