Aboveground herbaceous mass, vegetation cover fraction, LAI are monitored in sites located within the Hombori super-site and representatives of the 3 main components of the landscape: sand dunes (Agoufou, Hombori Hondo, Tara and Timbadior), erosion surface (Eguerit), seasonally inundated clay soils (Kelma plain) and millet (Bilantao). For mass estimation, the herbaceous layer is monitored using a stratified random technique. Measurements are performed at least every month during the rainy season, from June to mid-October and twice during the dry season. LAI is estimated using hemispherical photographs. For the Kelma forest, hemispherical photographs are also used to derive the Plant Area Index (PAI).
