DESCRIPTION:Chestnut stands in Piemonte are presently suffering a severe de
 cline due to the concurrence of climatic and silvicultural factors. A proj
 ect funded by Piemonte region involving the Regional Chestnut Centre and I
 PLA S.p.A. started in 2018 with the aim of defining technical guidelines f
 or proper interventions in declining stands. The present contribution deal
 s with the activities of spatial monitoring of declining areas through sat
 ellite images interpretation and GIS analysis making use of QGIS and Grass
  tools. Methodological approach was based on the selection of Sentinel 2A 
 e 2B images taken at the beginning and at the end of the summer season in 
 2017\, 2018 e 2019 on a test area. Those images were then processed calcul
 ating some indexes with raster functions implemented in QGIS. NDWI Normali
 zed Difference Water Index (B8-B12/B8+B12) resulted the more sensible to t
 he presence of declining stands \nAccurate mapping of areas suffering diff
 erent degree of damages on the whole Region was then carried out starting 
 from a preliminary analysis of experimental parcels surveyed on the field.
