Diversity and use of trees and shrubs in smallholder farming systems in the Colombian Andes
This article describes the diversity and use of trees and shrubs in smallholder farming systems in three municipalities of the department of Boyacá in the Colombian Andes, and tests the relations between species richness, use, and a set of socio-economic and structural variables. We conducted ethnobotanical walks and semi-structured interviews on 24 farms to characterize all tree and shrub species. In total, we recorded 142 species with a predominance of natives (88) versus exotics (54). Species richness ranged between four and 40 (X = 25.17; SD = 10.13) per farm and was homogeneous among the municipalities (P > 0.05, Kruskal-Wallis test). We recorded 52 wild species, eight of them endemic, all representative of the surrounding native flora, of which 23 % had some type of use. Cultivated species were mostly represented by exotics that had been planted primarily as live fences, ornamentals, or edibles. Species richness was positively correlated with the size of the farms (rs = 0.664, P<0.001) and negatively with their proximity to areas with natural vegetation (rs = -0.515, P = 0.010). Smallholder agriculture favors the establishment of trees and shrubs; we, therefore, stress the important role of these productive systems for the conservation of biodiversity in the Colombian Andes.

Este artículo describe la diversidad y uso de árboles y arbustos en sistemas de pequeña agricultura en tres municipios del departamento de Boyacá en los Andes colombianos y analiza las relaciones entre la riqueza, el uso de las especies y un grupo de variables socioeconómicas y estructurales. Se realizaron caminatas etnobotánicas y entrevistas en 24 fincas para caracterizar todas las especies de árboles y arbustos. En total, se registraron 142 especies con predominio de las nativas (88) versus las exóticas (54). La riqueza de especies varió entre cuatro y 40 (X = 25,17; SD = 10,13) por finca y fue homogénea entre los municipios (P > 0,05, Kruskal-Wallis test). Se registraron 52 especies silvestres, ocho de ellas endémicas, todas representativas de la flora nativa circundante, de las cuales 23 % tienen algún tipo de uso. Las especies cultivadas estuvieron representadas principalmente por plantas exóticas sembradas, por lo general, como cercas vivas, ornamentales o comestibles. La riqueza de especies se correlacionó positivamente con el tamaño de las fincas (rs = 0,664, P<<0,001) y negativamente con la proximidad de las fincas a áreas con vegetación natural (rs = -0,515, P = 0,010). La pequeña agricultura favorece el establecimiento de árboles y arbustos, por lo cual, se enfatiza el importante papel de estos sistemas productivos para la conservación de la biodiversidad en los Andes colombianos.
