NAVARRO GARZA, Hermilio et al. Diversity of useful species and agroforestry systems. Rev. Chapingo ser. cienc. for. ambient [online]. 2012, vol.18, n.1, pp.71-86. ISSN 2007-4018.  https://doi.org/10.5154/r.rchscfa.2010.11.124.

Biodiversity management and use sustain multifunctional agro-ecosystem services, such as: food supply, fodder, firewood, timber, fuel, fiber, and aquifer recharge, among others. The loss of biodiversity and increased risks of its deterioration, frequently inherent to several human activities, raise the need to develop institutional and social capacities for their restoration and conservation. The objective of this work was to identify and describe the diversity of trees and bushes, their uses and types of agroforestry systems. It is important to know the multiplicity of uses, as a synthetic expression of functional logic that makes agroforestry land systems viable. The study's descriptive methodology was based on participatory workshops designed to know the diversity of resources and uses. The subsequent steps involved: selection of families, transects, interviews, records, and collecting and classifying specimens. In total, 81 species and 34 families were identified. Diversity is amplified by the multifunctionality of uses for 55.6 % of the species: 7.4 % with 5 types of uses; 11.1 %, with 4 types; 14.8 % with 3 types; and 22.2 %, 2 types. Types of uses: firewood, 41 species; medicinal 30 species, tool-making 29, timber, 25; feed purpose, 23; forage species, 20, and 6, hedgerows. Some 91.7 % of households use agrosilvicultural systems and 41.7 % silvopastoral ones, according to various socio-economic purposes and use combinations.
