- •
Enhanced Vegetation Index (EVI) was used to assess diet composition and quality in Pyrenean chamois.
- •
In spring and winter the EVI was negatively related to diets low in fibre and Calluna but positively to diets high in nitrogen, Festuca, Forbs and Trifolium.
- •
During the summer season, the EVI was not related to diet components of chamois.
- •
Remote sensing can be used as a tool for monitoring nutritional quality of large herbivore populations in management programmes.
