Abstract Climate and land‐use changes are contributing to impacts on global ecosystem functioning. These effects particularly severe in areas undergoing land abandonment extreme wildfire events, such as the Mediterranean regions of Iberian Peninsula. Previous studies have evaluated management fire mitigation biodiversity (species distribution species richness), but how strategies influence functional diversity remains unexplored. This study investigates alternative land‐fire may affect diversity. We modeled for 2050 Transboundary Biosphere Reserve Gerês‐Xurés (Portugal‐Spain). Land‐use scenarios simulated processes (“business‐as‐usual”—BAU) implementation EU rural policies (“high nature value farmlands”—HNVf), were combined with three suppression levels. Species models (102 vertebrates) projected each scenario, indices consequently calculated. The highest richness was predicted BAU scenarios, probably representing benefits unique that deliver singular functions. HNVf provided divergence, indicating a high niche differentiation low resource competition amongst agricultural communities. most beneficial scenario functioning, while did not Despite proneness burn our area firefighting its regime, expected greater than findings suggest different facets will be unevenly influenced by fire–landscape dynamics driven implemented upcoming decades.

The assessment of fire effects in Aleppo pine forests is crucial for guiding the recovery burnt areas. This study presents a methodology using UAV-LiDAR data to quantify malleability and elasticity four areas (1970, 1995, 2008 2015) through statistical analysis different metrics related height structure diversity (Height mean, 99th percentile Coefficient Variation), coverage, relative shape distribution strata (Canopy Cover, Canopy Relief Ratio Strata Percent Coverage), canopy complexity (Profile Area Profile Change). In general terms, decreases over time forest ecosystems that have been affected by wildfires, whereas higher than what has determined previous studies. However, particular specificity detected from 1995 fire, so we can assume there are other situational factors may be affecting ecosystem resilience. LiDAR uni-temporal sampling between sectors control aids used understand community resilience identify stages P. halepensis forests.
