Short Summary

This study investigated the relationship between drought and vegetation in Poland's forests from 2003 to 2023, finding that critical response months and optimal drought accumulation periods vary across different regions, elevations, and tree species.

Objective

• Investigate spatial and temporal variability in drought–vegetation relationships across Poland

Study Configuration

• Spatial Scale: National scale (Poland), with a focus on forested areas
• Temporal Scale: 2003 to 2023, with monthly data resolution

Methodology and Data

• Models used: None mentioned; analysis based on remote sensing data and indices
• Data sources:
  • CORINE Land Cover datasets for stable forest mask identification
  • MODIS imagery for Normalized Difference Vegetation Index (NDVI) calculations
  • Standardized Precipitation Evapotranspiration Index (SPEI) calculated from precipitation and temperature data

Main Results

• Critical response months: June, July, and August, with 82.23% of pixels responding in summer
• Optimal SPEI time scales: SPEI‐1 to SPEI‐4 collectively accounted for 56.16% of the analysed forest area; SPEI‐2 was the dominant optimal time scale (18.59%)
• Spatial and ecological heterogeneity observed across natural‐forest regions, elevation classes, and dominant tree species

Contributions

• This study provides a multiscale, spatially explicit framework for drought monitoring and regionally differentiated forest management in Poland
• Highlights the importance of considering regional differences in drought–vegetation relationships when developing forest management strategies
