“…One observer recorded all bird individuals heard and seen within a stand during a 20 min period within 3 hours after sunrise. We avoided double counting the same individuals by drawing the approximate positions of birds in virtual concentric circles around the observer's position (Prodon and Lebreton 1981). Abundance index of each stand was calculated as the sum of the heard and seen birds, using a semi-quantitative abundance index where a territorial male or pair was noted as 1 and a non-singing bird was noted as 0.5 (Bibby et al 2000).…”

• Poplar plantations should not be used as surrogate habitat for native riparian forests with the aim of preserving bird species diversity.• Native riparian forests should be preserved or restored as far as possible.• Bird communities occurring in poplar plantations can still accommodate rich communities of forest bird species, providing that suitable management is applied at local and landscape levels. AbstractIn Mediterranean areas, riparian zones are particularly important for maintaining biodiversity. Nevertheless, the native vegetation in these zones has been modified or lost at an alarming rate during the last decades. The main objective of this study was to investigate the influence of poplar plantations on bird diversity in riparian zones, in order to estimate the ecological implications of a substantial expansion of poplar plantations. Breeding birds were sampled by the point-count method in twenty-four poplar plantations of I-214 clone, according to a factorial design combining stand age and understory management. Furthermore, the three native riparian forests remaining in the study area were also surveyed. Explanatory variables included (1) dendrometric, (2) understory and (3) landscape variables within six different radii of circular buffers. The species richness and abundance index were higher in riparian forests than in poplar plantations. Landscape variables (percentage of poplar plantations in the surrounding landscape) strongly influenced bird diversity in poplar plantations. Furthermore, at the local scale, understory cover was also a key factor in shaping bird assemblages. This suggests that poplar plantations should not be used as surrogates for native forests. Nevertheless, poplar plantations can still accommodate rich communities of forest bird species, providing that suitable management is applied at local and landscape levels.

“…Por otro lado, su regresión en los últimos años es también compatible con un patrón natural de variación interespecífica en las tendencias de muchas especies de la avifauna española teniendo en cuenta sus rasgos autoecológicos (Seoane y Carrascal, 2008). Además, el crecimiento de la vegetación en zonas de matorral por sucesión natural hacia formaciones forestales, tras el abandono de los usos tradicionales del campo en muchas regiones españolas, ha podido influir negativamente en la especie atendiendo a sus preferencias de hábitat (Prodon y Lebreton, 1981;Tellería y Potti, 1984). En cualquier caso, su distribución restringida a la península Ibérica y su tendencia demográfica negativa en los últimos años sugieren que la catalogación de «Casi Amenazada» (Near Threatened) sea adecuada.…”

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.
