Abstract

Fodder shrubs and trees have both economic as well as ecological values in most extensive systems of arid and semiarid regions.

   As hypothesis, there is a relationship between the litterfall pattern and the foliar biomass production in forest plantations of semiarid areas, depending on the different seasons and species.

   The studied species were: Acacia berlandieri (Benth.), Acacia wrightii (Benth.), Ebenopsis ebano (Berl.) Barneby, Havardia pallens (Benth.) Britton & Rose and Helietta parvifolia (Gray) Benth.

   The foliar biomass was evaluated seasonally, from the dry weight of a representative branch of each species. The litterfall was collected every 15 days through litter traps installed under tree canopies, in experimental plantations of 30 years old, in the semi-arid zone of northeastern Mexico.

   There were highly significant differences (p<0.01) both among species as seasons in the foliar biomass values, whereas there were no significant differences (P>0.05) among species in litterfall, but highly significant differences (P<0.01) among seasons. The foliar biomass reached the maximum production in summer (9029 kg ha-1) with E. ebano, while the lowest value (103 kg ha-1) was recorded with A. wrightii in winter. The litterfall greatest accumulation occurred in winter (296 kg ha-1) with A. wrightii. A significant linear correlation (R2=63%) was determined between accumulation of litterfall and foliar biomass production.

   As conclusion, the litterfall pattern is related to the foliar biomass production, depending on the seasons and species. That constitutes a practical tool for the management of the forest ecosystems in semiarid areas.
