"The mountain region of Tabasco, in the south-east of Mexico, is a tropical zone where diverse silvopastoral systems (SPS) are practised; the principal SPS in the region are scattered trees on grasslands and living fences, which include native or introduced grasses associated with diverse trees. The more important trees in the SPS of the mountain region include native species Brosimum alicastrum, Bursera simaruba, Byrsonima crassifolia, Castilla elastica, Cedrela odorata, Ceiba pentandra, Cordia alliodora, Enterolobium cyclocarpum, Erythrina sp Gliricidia sepium, Guazuma ulmifolia, Haematoxylum campechianum, Pachira aquatica, Swietenia macrophylla and Tabebuia rosea. These species offer diverse products, uses and environmental benefits, derived from their use as hedges, shadow, human food, ornamental, medicinal, firewood, housing construction materials, wood, fodder or soil fertility conservation purposes. Multipurpose native trees of the SPS in the mountain region of Tabasco show the importance and multiple benefits that could be obtained from well-known and adapted species, which contribute to a better use of the available resources and to a higher sustainability of the system."
