Environmental drivers and operational practices influencing early establishment of Araucaria araucana

This dataset was used to assess how environmental spatial-scale factors (e.g., fire severity and distance to fallen logs) influence the early establishment of Araucaria araucana seeds and post-fire microclimate following direct seeding. Early establishment was evaluated through seed predation, seedling emergence, seedling survival, annual seedling height growth, and successful establishment. Microclimate variables included daily maximum air temperature, vapor pressure deficit (VPD), and soil moisture. Both early establishment and microclimate were analyzed as response variables using Generalized Linear Mixed Models (GLMMs). We considered two spatial-scale groups of predictors: Stand-scale factors: fire severity (measured via delta Normalized Burn Ratio, dNBR), Heat Load Index (HLI), Topographic Position Index (TPI), and elevation; Microsite-scale factors: distance to fallen logs (near/far microsites), soil moisture, and log diameter. We also evaluated the effect of sowing season (spring vs. autumn in the Southern Hemisphere) and compared results between seasons. The provided data tables and R scripts allow full replication of the analyses, figures, and results included in the manuscript "In the right place at the right time: Microsite and sowing season drive post-fire restoration of an endangered conifer", submitted for publication in Ecological Applications.
