Wildlife are essential in this process by providing ecological services that can facilitate forest resiliency in response to timber harvesting. This study identified the negative effect of eucalyptus plantations on amphibians and showed that the response of this taxon to fire is partially shaped by species-specific bioregion affinityĬontemporary forest management often requires meeting diverse ecological objectives including maintaining ecosystem function and promoting biodiversity through timber harvesting. The occurrence of Atlantic species did not change with fire whereas the number of Mediterranean species increased at sites affected by high-severity fires. Both Atlantic and Mediterranean groups showed higher species richness at native than at exotic points. higher richness in the native forest) and fire severity. Species richness per point varied depending on both forest type (i.e. We examined the influence of forest type and fire severity on the number of amphibian species detected per point (species richness). Water points were sampled in two different periods: just after the fire to report direct mortality, and two years after the fire to evidence amphibian resilience. We sampled 33 water points in native (mainly oak) and exotic (eucalyptus) forests. This area is a biogeographical crossroad where Atlantic and Mediterranean amphibian species can coexist in the same ponds. We examined the response of amphibian species to fire severity after a 1600-ha fire in a fire-active region located in the northwestern Iberian Peninsula. In this scenario, some taxa, such as amphibians, may be increasingly vulnerable. Climate and socioeconomic factors are modifying fire regimes.
