Abstract

An area of natural vegetation with bush dominance was studied under two forestry treatments. The first one was clear cutting, in which vegetation was under the direct influence of sunlight. The second treatment was shaded, in which vegetation was under the shade effects caused by a tree layer, with a cover of 51 p. 100. For both treatment cuttings were done 20 cm above the soil surface. To each treatment, 1, 2, 3 and 4 cuttings were applied each year. Total aerial biomass production for clear cutting (4.7 t/ha/year) resulted in significantly more abundant biomass than the shaded treatment (2.0 t/ha/year) (P < 0.05). Different cutting frequencies produced significant differences in mean biomass production in the shaded treatment (P < 0.05). Species that produced more aerial biomass in both treatments were Acacia berlandieri, Viguera stenoloba, Pithecellobium pallens, Acacia rigidula, Cordia boissieri, Eysenhardtia polystachya and Celtis pallida.
