Forest fires are key ecological factors affecting pine forests globally. Understanding impacts of varying fire intensities on forest ecosystem components is crucial for predicting recovery and informing management. This study aimed to assess effects different surface structural forests, including tree canopy, herbaceous layer, soil horizons, identify relationships between intensity parameters.

Herbaceous layer composition showed significant variations all life-form traits across intensities.

The integration of geodiversity elements and contexts into fire management frameworks remains limited due to a lack actionable tools for assessing geosite sensitivity. This study addresses this gap by developing testing mechanistic model evaluate soil lithological sensitivity, using database Tasmanian geosites at various temperature thresholds. Initial results indicate the utility approach distinguish between sensitive robust geosites, providing simple delineation relative sensitivities in situ elements. A subsequent iterative applied modelled outputs an existing database, giving coarse indicators sites with propensity be modified fire. With static inventory, allows decision-makers develop new risk parameters burns wildfires. Geographically complex environments have led misalignments boundaries broader processes, data inaccessibility remote or offshore sites, as both destructive formative agent; these must all resolved. Future work should consider necessity incorporating values, recovery trajectories, hydrological processes sensitivity assessments. concludes recommendations refining enhance its managers, ultimately contributing strategies geoconservation planning.
