Post-Fire Regeneration and Pine Invasion in Endangered Chilean Forests, 2018-2021

Claudia Leal-Medina's research data examines the early post-fire response of critically endangered Nothofagus alessandrii forests and Pinus radiata invasion following the 2017 'Las Máquinas' megafire in central Chile. The 4.5 MB PDF likely contains analysis of fire severity via Sentinel-2 dNBR, vegetation recovery via PlanetScope NDVI and MSAVI2 time series from 2018 to 2021, and field measurements of tree density and radial growth. Results show higher resprouting rates in severely burned sites and a direct relationship between fire severity and P. radiata invasion levels.

Use Cases

• Modeling vegetation recovery dynamics based on NDVI and MSAVI2 time series mentioned in the description
• Analyzing the relationship between satellite-derived fire severity (dNBR) and on-ground invasion density
• Studying tree growth responses (radial growth) to different fire severity classes
• Assessing the competitive dynamics between native resprouting and invasive pine establishment post-fire

Strengths

• Includes specific quantitative findings, such as 70% resprouting rate in high-severity sites and 9,760 ind/ha invasion density
• Uses multi-source remote sensing data (Sentinel-2 and PlanetScope) for fire severity and vegetation analysis
• Covers a defined time period (2018-2021) for post-fire monitoring
• Focuses on a critically endangered and geographically specific forest ecosystem

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is presented in a PDF format, which may require extraction for computational analysis
