“…The promise of compensation may lead to that more activities that damage biodiversity are permitted, and often there is little evidence that compensation efforts are efficient (Maron et al, 2012). However, field studies in Northern Europe have shown that created high stumps are, indeed, used by hundreds of insect species, including many that are redlisted (Lindhe and Lindelöw, 2004), and in Northern America several cavity-dependent bird species nest successfully in high stumps (Hane et al, 2012). It makes a difference where and of which trees the high stumps are created (Jonsson et al, 2010;Lindhe and Lindelöw, 2004).…”

“…Snags are especially important features within forests because they provide habitat that is used by nearly a third of all forest‐dwelling organisms (Thomas , Newton ). Snags are often deemed critically important for cavity‐nesting birds because members of this group use snags for nesting and foraging (Hallett et al , Walter and Maguire , Cooke and Hannon , Hane et al ), and snag availability can limit cavity‐nesting bird populations (Li and Martin , Schreiber and DeCalesta ). Strong cavity‐excavating bird species, namely woodpeckers (family Picidae), exert a disproportionate effect on the ecological community through their foraging activities and via the creation of nesting and roosting cavities within snags which, in turn, supports a diversity of species that require cavities but cannot create them on their own (e.g., secondary cavity nesters; Drever et al , Hane et al , Bunnell ).…”

Snags are important habitat features for many forest‐dwelling species, so reductions in the number of snags can lead to the loss of biodiversity in forest ecosystems. Intentional snag creation is often used in managed forests to mitigate the long‐term declines of naturally created snags, yet information regarding the use of snags by wildlife across long timescales (>20 yr) is lacking and prevents a complete understanding of how the value of created snags change through time. We used a long‐term experiment to assess how harvest treatment (i.e., small‐patch group selection, 2‐story, and clearcut) and snag configuration (i.e., scattered and clustered) influenced nesting in and foraging on 25–27‐year‐old Douglas‐fir (Pseudotsuga menziesii) snags by cavity‐nesting birds. In addition, we compared our contemporary measures of bird use to estimates obtained from historical surveys conducted on the same group of snags to quantify how bird use changed over time. Despite observing created snags for >750 hours across 2 consecutive breeding seasons, we found limited evidence of nesting activity. Only 11% of created snags were used for breeding, with nesting attempts by 4 bird species (n = 36 nests); however, we detected 12 cavity‐nesting species present on our study sites. Furthermore, nearly all nests (94%) belonged to the chestnut‐backed chickadee (Poecile rufescens), a weak cavity‐excavating species that requires well‐decayed wood for creating nest cavities. Our surveys also recorded few observations of birds using created snags as foraging substrates, with only 1 foraging event recorded for every 20 hours of observation. We detected 82% fewer nests and recorded 7% fewer foraging observations during contemporary field work despite spending >7.5 times more effort observing created snags relative to historical surveys. We conclude that 25–27‐year‐old created Douglas‐fir snags provided limited opportunities for nesting and foraging by most cavity‐nesting birds, and that the period of greatest use by this group occurred within 5–15 years of creation. © 2018 The Wildlife Society.

“…To account for spatial variation, we included the total number of shrubs in each plot, vegetation coverage above each nest, nest height, and an indicator variable of whether nests were in either spiny or nonspiny plants as fixed effects. We included study plot as a random effect to account for spatial variation not modeled with covariates (Hane et al 2012). We also included a nest random effect, allowing the model intercept to vary by nest.…”

Factors associated with nest survival of Black‐throated Sparrows, desert‐breeding nest‐site generalists

Black‐throated Sparrows (Amphispiza bilineata) are common breeding birds throughout the desert regions of North America and can be considered nest‐site generalists. Information about how spatial (e.g., vegetation) and temporal factors influence nest survival of these sparrows is lacking throughout their range. Our objective was to examine the spatial and temporal factors associated with nest survival of Black‐throated Sparrows at the nest and nest‐patch scales in the predator‐rich environment of the northern Chihuahuan Desert of New Mexico. We used a logistic‐exposure model fit within a Bayesian framework to model the daily survival probability of Black‐throated Sparrow nests. Predation was the leading cause of nest failure, accounting for 86% of failed nests. We found evidence of negative associations between nest survival and both vegetative cover above nests and shrub density within 5 m of nests. We found no support for other habitat covariates, but did find strong evidence that daily survival rate was higher earlier in the breeding season and during the egg‐laying stage. A decline in nest survival later in the breeding period may be due to increased predator activity due to warmer ambient temperatures, whereas lower survival during the incubation and nestling stages could be a result of increased activity at nests. A generalist approach to nest‐site selection may be an adaptive response to the presence of a diverse assemblage of nest predators that results in the reduced influence of spatial factors on nest survival for Black‐throated Sparrows.
