“…Species such as Ovenbird and Swainson's Thrush, which are associated with older forest age classes, would therefore benefit from forest harvesting guidelines that favor the maintenance of stands on the landscape that are allowed to grow beyond traditional harvest rotation ages (Hobson and Bayne 2000a,b,c, Cumming and Diamond 2002, Bayne et al 2010. Conversely, similar to previous work (Van Wilgenburg and Hobson 2008, Kardynal et al 2009, 2011, we also showed that the abundance of Mourning Warbler and White-throated Sparrow increased where disturbance had occurred. Given the diverse habitat needs of boreal forest birds, using historic natural disturbance regimes (also called "emulation of natural disturbance"; Stockdale et al 2016) to determine target forest age-class distributions may therefore improve upon historic even-aged forest management and benefit a broader range of species.…”

ABSTRACT. The boreal forest provides important breeding habitat for many migratory songbirds; however, changes in disturbance regimes have led to concern for populations breeding there. Monitoring data to track changes in boreal forest bird populations are scarce. Therefore, we repeated surveys at historic research sites in aspen-dominated boreal mixedwood forest in central Saskatchewan, Canada, to test for changes in abundance in different forest age classes. We used GIS analyses and habitat data to test whether observed changes in abundance were correlated with within-stand changes in habitat over approximately 20 years. Eight of the ten species examined showed evidence for change in abundance. Trends from our study showed little correlation with regional trends from the North American Breeding Bird Survey (BBS) and generally displayed greater magnitude and precision. Species associated with closedcanopy forests declined more rapidly than suggested by BBS surveys, whereas species associated with disturbance generally had opposite trends to the BBS. Decreased abundance of species such as Swainson's Thrush (Catharus ustulatus) and Yellow-rumped Warbler (Setophaga coronata) correlated with loss of forest cover from fire or harvesting. Conversely, changes in the abundance of species associated with early successional forest and canopy gaps were primarily correlated with within-stand disturbances (e.g., Magnolia Warbler [Setophaga magnolia]) and changes in the proportion of the stands composed of conifers (e.g., White-throated Sparrow [Zonotrichia albicollis]). We suggest repeating historic surveys and comparing trends with other monitoring programs to provide a weight-of-evidence approach to assess overall support for changes in species' status for regions where data are sparse. Our results are consistent with previous studies that predict that changes in the forest age-class distribution could alter boreal forest bird abundance and community composition. Long-term conservation plans should integrate projected land-use and climate effects on boreal forest bird populations.Variations temporelles de l'abondance aviaire en forêt mixte boréale dominée par le peuplier dans le centre de la Saskatchewan, Canada RÉSUMÉ. La forêt boréale compte d'importants milieux de nidification pour de nombreux passereaux migrateurs. Toutefois, en raison des changements advenus dans les régimes de perturbation, les populations qui y nichent soulèvent des préoccupations. Les suivis mis sur place pour détecter les variations de populations d'oiseaux forestiers boréaux sont rares. Nous avons donc refait des relevés à des sites de recherche historiques en forêt mixte boréale dominée par le peuplier dans le centre de la Saskatchewan, Canada, afin de tester si l'abondance avait changé selon les différentes classes d'âge des forêts. Au moyen d'analyses SIG et de données d'habitat, nous avons testé si les variations observées dans l'abondance étaient corrélées avec les changements d'habitat à l'échelle des peuplements sur une période d'environ ...

“…Despite the widespread use of riparian reserves (FEMAT, 1993;Kardynal et al, 2009), there has been little experimental evaluation of their effectiveness (Darveau et al, 1995;Kiffney et al, 2003). For example, what reserve width is needed to maintain litter flux relative to fully forested streams?…”
