Data: Landscape resistance, uncertainty, and prioritized ecological corridor layers for the protected area network of the Araucanía Region, Chile

This dataset is part of the study "Designing ecological corridors for connectivity in fragmented protected areas: a transferable framework to guide conservation policy." It contains the spatial layers underlying the landscape connectivity analysis: three landscape resistance raster layers (model-based, expert-based, and hybrid), their corresponding uncertainty normalized raster layers (model-based and expert-based), and the final network of 24 prioritized ecological corridors derived from the hybrid resistance matrix, delineated as 1-km buffers around each least-cost path and attributed with native forest cover, land tenure density, and management category (preservation, active restoration, negotiated private conservation, or incentive-based restoration). The resistance and uncertainty layers represent high-resolution spatial friction surfaces, allowing empirical species distribution models to be directly contrasted with structured expert judgment.
