Abstract (EN): Remote sensing data has led to the development of spectral indices for monitoring ecosystems, land surface changes, and water quality. These indices are used in various applications, including agricultural and wildfire monitoring, to understand vegetation cycles and disturbances. Wildfire research focuses on the effects of extreme occurrences, and understanding forest ecology after severe events is crucial for evaluating forest health. Vegetation Indices (VIs) are frequently used in forest and wildfire monitoring studies to account for plant biophysical, biochemical, and physiological characteristics. Normalized Difference Vegetation Index (NDVI), Normalized Burn Ratio (NBR), Normalized Difference Infrared Index (NDII), and Plant Senescence Reflectance Index (PSRI) are indices used to assess vegetation conditions. VIs are valuable resources for monitoring post-wildfire occurrences, as they measure biophysical changes and provide comprehensive monitoring of the affected area, playing a crucial role in assessing the health of forests. Pre-wildfire vegetation conditions monitoring is also important for implementing preventative measures in critical regions to increase wildfire defense and identifying wildland fuels is crucial for improving fuel management actions. This research aims to demonstrate the effectiveness of chosen VIs and fuel models as tools to assess pre-fire conditions, enabling decision-makers to increase wildfire surveillance and landscape resilience in Vale do Sousa, Portugal's northern area. Despite limitations, this approach is valuable, especially in terms of financial or logistical constraints. Moreover, combining VIs with fuel hazard models can improve fuel reduction efforts. © 2025 by SCITEPRESS - Science and Technology Publications, Lda.
