In the fire-prone tropical savanna landscapes of northern South America, forest edge effects significantly shape tree structural integrity and functional traits, with implications for ecosystem resilience, carbon storage, biodiversity. This study examines how effect, intensified by fire, affects species dominance, structure, trait distributions in this region. Using non-metric multidimensional scaling (NMDS) generalized additive mixed models (GAMMs), we analyzed changes abundance variables (biomass, basal area, height, wood density), as well leaf (leaf thickness, moisture, dry matter content (LDMC), specific area (SLA)) stem (bark thickness stem-specific density) traits across edge-to-interior gradients. The key findings indicate significant reductions height (F = 19.27, p < 0.01), 6.52, biomass 5.44, 0.01) near edges. Leaf moisture 11.8, (SLA, F 7.02, increased at edges, reflecting microenvironmental gradients, heightened fire sensitivity seen like bark 11.88, 0.01). Fire-affected areas displayed adaptive shifts, suggesting a compounded resilience but potential convergence, limiting capacity under climate stressors. These emphasize ecological significance edge–fire interactions, advocating conservation strategies to enhance diversity stability. Our underscores need targeted management bolster biodiversity within these dynamic pressures intensify.
