description:Abstract;Quantification of seasonal dynamics of herbaceous vegetation and tree foliage on sites for which the long term dynamics is also monitored (see CL.VegHerb_G). The main objectives are to analyze the different processes that control primary production and degradation of vegetation and to test models (e.g, STEP).
description:SeriesInformation;Aboveground herbaceous mass, vegetation cover fraction, LAI is monitored in sites located within the Hombori super-site and representatives of the 3 main components of the landscape: sand dunes (Agoufou, Hombori-Ondo, Tara and Timbadior), erosion surface seasonally inundated clay soils (Kelma) 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).
