Key Factors Influencing Post-Fire Vegetation Recovery in Pinus halepensis Forests: Divergent Effects for Canopy and Shrub Species
Aims
Rapid revegetation of burnt forest is essential for recovering ecosystem functioning, especially in the context of climate change–driven shifts in fire regime. This study aimed to provide a comprehensive understanding of how abiotic factors (topography, fire behaviour) and biotic factors (pre-fire forest characteristics, plant reproductive strategies, land-use trajectories) influence the recovery of Pinus halepensis forests, identifying regeneration vulnerabilities that could inform management practices.
Location
A P. halepensis forest burnt in 2019 (4000 ha) in NE Iberian Peninsula.
Methods
We established 72 sampling sites within the burnt forest, covering gradients of pre-fire canopy cover (PCC), topography, fire severity and land-use history. At each site, we recorded the abundance of P. halepensis seedlings within a 100-m2 plot. We also conducted a floristic inventory of all associated woody species along two parallel 20-m transects to assess woody species cover, richness and distribution. Woody species were classified based on their post-fire reproductive strategies (obligate seeding, facultative resprouting and resprouting) to explore the relationship between functional characteristics and plant distribution along the studied gradients.
Results
Northern exposures enhanced the abundance of P. halepensis, whereas coexisting woody species cover was higher on southern ones, probably due to the contribution of obligate seeders, as fire-responsive reproductive traits vary along the north–south gradient. PCC boosted pine regeneration and species richness, while high fire severity reduced both cover and richness of woody species, likely due to damage to reproductive structures.
Conclusions
We show that the drivers of post-fire regeneration influence in different and even divergent ways the vegetation components considered (canopy and shrub layer), as in the case of aspect. From a management perspective, post-fire forest interventions should be tailored to restoration objectives and to the post-fire vegetation communities that better respond to them.
期刊介绍：
The Journal of Vegetation Science publishes papers on all aspects of plant community ecology, with particular emphasis on papers that develop new concepts or methods, test theory, identify general patterns, or that are otherwise likely to interest a broad international readership. Papers may focus on any aspect of vegetation science, e.g. community structure (including community assembly and plant functional types), biodiversity (including species richness and composition), spatial patterns (including plant geography and landscape ecology), temporal changes (including demography, community dynamics and palaeoecology) and processes (including ecophysiology), provided the focus is on increasing our understanding of plant communities. The Journal publishes papers on the ecology of a single species only if it plays a key role in structuring plant communities. Papers that apply ecological concepts, theories and methods to the vegetation management, conservation and restoration, and papers on vegetation survey should be directed to our associate journal, Applied Vegetation Science journal.
