Traditional uses of dispersed trees in the pastures of the mountainous region of Tabasco, Mexico

The rapid deforestation in the state of Tabasco due to extensive livestock farming has resulted in the decrease of the original forest cover. Only 4% of the original vegetation remains and that vegetation is concentrated in the mountainous regions of the state. This destructive process continues due to support by the current government livestock policies. Under these circumstances, the traditional silvopastoral systems of dispersed trees can present an option for reversing and mitigating deforestation practices. The objective of this study was to generate information on the tree species common to silvopastoral systems of dispersed trees in the pastures for two mountainous areas in Tabasco. In the study, 64 tree species, representing 26 plant families were identified. All species were characterized as multipurpose, with at least three reported uses and a maximum of seven for each species. In total, nine categories of local uses were identified for the trees. The main category of use was fuel (firewood), followed by timber and shade for the livestock. Although leguminous species (Fabaceae) were dominant, these species were utilized for uses other than the provision of fodder. Since 12 of the total species identified were recognized as sources of food for animals; the assumption that livestock farmers do not recognize the utility of these species for improving production yields is apparent. The results suggest that there is potential need to expand research and offer further education on the subject in Tabasco.
