  • Abstract

Much of the northeastern Mexican surface, is covered with vegetation consisting of shrub, composed of a wide variety of species, with diverse structures and associations, which gives to the landscape a toponymy known as “thorn- scrub”. The main use is for extensive pastoral and forestry purposes, generally without a management plan. The quantitative determination of the vegetation coverage was important to establish strategies for optimal utilization of vegetation by livestock and wildlife. In a typical scrub of northeast of Mexico, and experimental plantations of over 28 years with native species, an inventory was conducted with the aim of evaluating forage availability. Coverage by woody species and herbaceous biomass were determined. The results showed highly significant differences (p<0.001) between types of management by species, with maximum coverage value of 19.68 m2 tree-1of Ebenopsis ebano and only 2.73 m2 tree-1 for Acacia berlandieri in their native area. As for biomass, Acacia wrightii in experimental condition and Acacia berlandieri in its habitat presented higher productions, with values of 0.83 and 0.79 kg ha-1, respectively. Ebenopsis ebano in its native area produced the lowest biomass (0.19 kg ha-1) of the experiment.
