“…Our model predicted woodpecker occupancy probability dropping off markedly in the first few years following a fire. This finding is consistent with other studies that report the strongest positive responses of Black-backed Woodpecker populations to fire disturbance 1-3 years post-fire (Murphy and Lehnhausen 1998, Saab et al 2007, Nappi and Drapeau 2009, during which time birds are likely responding to increased abundance of wood-boring beetle larvae (Villard andBeninger 1993, Murphy andLehnhausen 1998). Yet, the relationship between fire age and occupancy may be more complicated than suggested by our model.…”

“…Wildfire and salvage logging are priority management issues in coniferous forests of western North America (Hutto 2006), and the Black-backed Woodpecker (Picoides arcticus) was recently selected by the USDA Forest Service as a management indicator species (MIS) for snags in burned forests of the Sierra Nevada (USDA Forest Service 2007). Highseverity stand-replacing wildfires have been suggested to be particularly important for this species (Hutto 1995, Murphy and Lehnhausen 1998, Kotliar et al 2002, Smucker et al 2005, Hanson and North 2008, with habitat quality peaking within the first few years of a high-severity fire (Murphy and Lehnhausen 1998, Saab et al 2007, Nappi and Drapeau 2009. However, the species may also respond positively to lower intensity fires such as controlled burns (Russell et al 2009), and it also occurs to some extent in unburned forests (Dixon andSaab 2000, Tremblay et al 2009).…”

Abstract. The Black-backed Woodpecker (Picoides arcticus) has been designated by the USDA Forest Service as a management indicator species for snags in burned conifer forests of the Sierra Nevada of California, USA. However, little is known about the characteristics that affect between-fire and within-fire habitat selection by the species in the region. Here we report on the first broad-scale survey of Black-backed Woodpeckers on wildfire-affected forests of the Sierra Nevada. We implemented a Bayesian hierarchical model to: 1) estimate Black-backed Woodpecker occupancy probability in fire areas burned within a time window of 1-10 years; 2) identify relationships between occupancy probability and habitat covariates (fire age, change in canopy cover pre-to-post fire, and snag basal area), elevation, and latitude; and 3) estimate detection probability and relate it to survey interval length and survey type (passive v. broadcast). We included random fire-area effects in our model of occupancy probability to accommodate clusters of nonindependent points surveyed within the larger set of fire areas. Mean occupancy probability was estimated to be 0.097. Elevation (after controlling for latitude) had the strongest effect on occupancy probability (higher occupancy at higher elevation) followed by latitude (higher occupancy at northerly sites). Fire age was also important; occupancy probability was about 43 higher on the youngest compared to oldest fires. Although the direction of regression coefficients were in the expected direction (positive), snag basal area and canopy cover change were of minor importance in affecting occupancy probability. There was some indication, however, that the importance of snag basal area increased with fire age. Weak links between occupancy and canopy cover change suggested the species uses a range of burn severities, and such heterogeneity may promote habitat longevity. Our estimate of overall detection probability (across all survey intervals) was 0.772. We found strong effects of survey interval length (higher for longer interval) and, especially survey type (higher for broadcast survey) on detection probability. Our modeling framework and implementation illustrates the flexibility of the Bayesian hierarchical approach for handling complexities such as estimating derived parameters (and variances) and modeling random effects, and should prove generally useful for occupancy studies.

“…Wildfires belong to the most important phenomena in landscape dynamics and play an important role in determining the distribution of birds typical of forests (Moreira et al 2003, Jacquet & Prodon 2009, Nappi & Drapeau 2009) and openhabitats (Dechant et al 2003, Pons & Bas 2005, Bouwman & Hoffman 2007, Menz et al 2009). Wildfires may provoke opposing changes in the distribution and biology of avian species, such as higher reproductive success (Nappi & Drapeau 2009), lower abundance (Moreira et al 2003), or higher abundance and species richness (Bouwman & Hoffmann 2007).…”

“…Wildfires may provoke opposing changes in the distribution and biology of avian species, such as higher reproductive success (Nappi & Drapeau 2009), lower abundance (Moreira et al 2003), or higher abundance and species richness (Bouwman & Hoffmann 2007). Some studies have determined that wildfires may have positive effects on the conservation and persistence of some threatened Mediterranean avifauna, since open habitats created in forests by wildfires are often occupied by more specialized and threatened species (Moreira et al 2001, Pons & Bas 2005, Brotons et al 2008, Clavero et al 2011) and habitat quality may improve compared to pre-fire situations after vegetation recovery (Real 2000, Menz et al 2009).…”

Pérez-Granados C., López-Iborra G. M., Serrano-Davies E., Noguerales V., Garza V., Justribó J. H., Suárez F. 2013. Short-term effects of a wildfire on the endangered Dupont's Lark Chersophilus duponti in an arid shrub-steppe of central Spain. Acta Ornithol. 48: 201-210. DOI 10.3161/000164513X678856Abstract. In Europe, Dupont's Lark Chersophilus duponti is a threatened open-habitat bird. Prescribed burning has sometimes been proposed for its conservation, but without evidence of its effectiveness. To evaluate the short-term effects of a summer wildfire on this species, we performed several transect counts in the burnt and unburnt parts of a shrubsteppe in central Spain. The same transects were counted within a three-year interval prior to the fire and were repeated during the first two springs after the fire. We also measured the vegetation during the first two springs after the fire. In the burnt area, we observed a decrease of about 85-100% in Dupont's Lark abundance, and about 7-15% in the control area. The disappearance of the scrub cover after fire and its slow regeneration, as well as the large increase in grass cover during the second year, may explain the decrease in this habitat-specialist bird species. Fire should be avoided in areas occupied by the Dupont's Lark, as its negative effects in the short-term may cause local extinctions. However, prescribed burning may be used in neighboring areas to create new open habitats that may be subsequently colonized by this species.
