  5. 5. Remote sensing-based monitoring of snow cover dynamics and its influence on vegetation growth in the Middle Atlas Mountains

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Keywords : shrublands; grasslands; forests; Morocco; mountains; monitoring; remote sensing; MODIS; snow; vegetation; Physical Geography; Ecosystem analysis; GIS; Earth and Environmental Sciences;

    Abstract : Endowed with diverse vegetation covers, the Middle Atlas Mountains receive substantial snowfall in winter, which contributes to plant hydration during the growing season. Using remotely-sensed imagery, this study aims to assess the trends in snow cover variations between 2000 and 2015, analyse the local influence of snowpack persistence on vegetation growth and evaluate the significance of this effect by comparing snow-fed and non-snow-fed sites.
