Habitat diversity is maintained by fires in fire-prone ecosystems of the Mediterranean Basin, and fire is a significant driver of plant and animal diversity in such ecosystems. We studied large mammal species in a Mediterranean habitat mosaic generated by recent fires. We performed a camera-trapping survey in Pinus brutia forests in southwestern Turkey between May 2009 and February 2010. The study area was structured by recently-burned and unburned habitat patches. A total of 2047 camera-trap days were obtained with 33 camera-trap stations which were established in three replicate study sites (each ~12 km2 in size) comprised both of burned (within the last 15 years) and unburned habitat patches. During the study period, we detected eight large mammal species including brown bear (Ursus arctos), caracal (Caracal caracal), and wild goat (Capra aegagrus), which are of conservation importance. Among these species, six were present both in recently-burned and unburned habitats; except the brown bear (only in burned sites) and the wild goat (only in unburned sites). A permutation test revealed that there is no significant difference in relative abundance of target species except the wild boar (Sus scrofa) which was observed in significantly higher abundances in burned sites than unburned ones (z = -2.3, P = 0.01). Our results suggest that habitat mosaics shaped by fire disturbance in Mediterranean pine forests support large mammal occurrence, and have important implications for the conservation of large mammals in frequently-burned Mediterranean ecosystems.
INTRO: This study contrasts the occurrence of large mammals between recently burnt habitat and unburnt habitat patches in a Mediterranean habitat mosaic in southwestern Turkey. Their results suggest no significant differences in the relative abundance of most of their target species, with the exception of the wild boar, which was found to be selecting for burnt sites. However, they found that habitat mosaics generated by fire support large mammals, which will be important for the conservation of large mammal species in a flammable system.
MERITS: This study is a nice, straightforward project, with clear and interesting results. The conservation significance of their results is well established.
CRITIQUE: More information regarding the proportion of burnt/unburnt habitat in each mosaic, and the different time-since-fire age classes would be useful. Perhaps further replication would increase the strength of the results.
DISCUSSION: The implications of this study are generally well established, with several species of conservation significance detected in the study. Knowledge of how large mammals are responding to different parts of a disturbed landscape will be important for the future conservation and management of these species in a fire-prone system. Perhaps the reasearch could discuss its implications on a more global scale, can the outcomes from this study inform fire management for biodiversity elsewhere?
