| This study evaluates the processes of recolonization of abandoned fields by native vegetation under conditions of intensive human activity (fire, intensive grazing, firewood cutting) in a semi-arid tropical region savanna of northern Cameroon. Secondary plant succession was studied in two series of formerly cultivated fields 1-35 yr after the beginning of the fallow period. Floristic changes and the dynamics of woody plant populations were compared between areas with vertisols (clay texture) and sandy soils, as a function of length of fallows. Vegetation changed continuously during the 35 years following field abandonment. However, a very abrupt break occurred between 6 and 10 yr, due to increasingly intense human pressure during this period. Up to that... |
