Pollinators play an essential role for ecosystem health and maintain biodiversity through the pollination of both native plants and domesticated crops. In Argentina, many of the fruits, vegetables and some cereal crops are dependent upon pollination for full fruit set. Worldwide, pollinator species are declining, especially in areas of agricultural intensiﬁcation due to the conversion of natural areas to large extensions of homogeneous crops that are devoid of ﬂoral and nesting resources for wild bees. In Argentina, cultivated area with intensive monoculture has increased during the last 60 years, producing biodiversity loss. Given that biodiversity would be associated with greater heterogeneity, a useful strategy to conserve the availability of pollinators in spaces managed by human and to increase level of yields and quality of production, would be to maintain wild vegetation and to increase crop diversiﬁcation.
However, few studies in semiarid zones of South America have explored these aspects as useful tools to enhance pollinator diversity and abundance in agroecosystems. San Juan, the study site of this project, is part of the desert Monte of Argentina and is the main producer of horticultural seed in the country. The majority of the producers of these productions correspond to family farmers. The characteristics of family farming and the fragility of this environment makes the agroecosystems of San Juan a good place to study how landscape heterogeneity could contribute to pollinators community’s maintenance and to the improvement of crop pollination service.
