Descripción
In fire-prone ecosystems, litter is a key component of surface fuels, and species assemblages play a relevant role in determining plant fuel characteristics. In this context, the introduction of alien species may alter fire regimes by modifying the structure and composition of pre-existing native communities. In central Argentina, Pinus halepensis is an alien species that has expanded over the high-altitude native grasslands, forming invasive populations that are increasing rapidly. This study aimed to evaluate changes in the litter flammability associated with this invasion process. We compared litter biophysical characteristics, litter flammability parameters and species-specific litter flammability between pine-invaded grasslands and adjacent, non-invaded grasslands. Dry biomass and bulk density of litter were significantly higher in invaded plots than in adjacent non-invaded plots (p < 0.001). Propagation, flame duration, maximum flame temperature, maximum flame height, and percentage of the sample burned were also higher in invaded plots than in adjacent non-invaded plots (p < 0.05). Regarding the species-specific flammability parameters, P. halepensis showed a similar ignition time to the native grassland species, whereas the maximum temperature reached was significantly higher for the invader. Overall, these results suggest that this species contributes significantly in altering fire behavior in the region, potentially increasing the fire severity in invaded grasslands, anreshaping long-term vegetation dynamics. High-altitude grasslands are ecosystems of high conservation value that provide key ecological and cultural functions. The invasion of P. halepensis may further intensify ecosystem degradation by increasing fire severity, altering post-fire recovery, reducing grassland resilience, and promoting long-term soil degradation in vulnerable mountain ecosystems.
