Resumo(s)
The Mediterranean area currently suffers a general decline of oak woodlands’ health and productivity. Cork oak (Quercus suber L.) and holm oak (Quercus ilex L.) are widely exploited in Portugal and are an important economical and ecological resource for the country. The Normalized Difference Vegetation Index (NDVI) is a common remote sensing index used as a proxy for vegetation biomass, chlorophyll activity, health and stress. NDVI can be monitored for 34 years (1984-2017) at 30-meter of resolution using Landsat imagery. The online platform Google Earth Engine (GEE) allows the free access and fast handling of this huge amount of satellite images. Objective: Providing to researchers, land owners and policy-makers a high-resolution map of cork and holm oak long-term trends for the whole Portugal
