Severalstudies confirm that biodiversity loss endangers ecosystem services (ES) supplyand human well-being. A better understanding of biodiversity?ESrelationships and effects of biodiversity loss on ES supply is needed. Theobjective was to determine relationships between potential biodiversity andthree ES in Patagonia where cattle ranching under silvopastoral use occurs. Weused grids of potential biodiversity (plant species richness) and three ES,provisioning (cattle stocking rate), regulating (CO2 sequestration)and cultural (geo-tagged digital-images). Potential biodiversity was negativelyrelated to provisioning, but no significant relations were detected withregulating and cultural. These relations showed regional differences related toforest landscape distribution. High values of regulating were found in southernareas being coincident with high potential biodiversity. Opposite trends(negative relationship with biodiversity) was observed for provisioning ineastern and western regions where provisioning decrease from N-S. Resultssuggest that provisioning do not overlap spatially with the higher values ofpotential biodiversity maps, which is an advantage for land use planning whenconservation and management requirements must be combined. Our results are thefirst contribution for Patagonia to underpin scientific and institutionalefforts to connect biodiversity conservation with ES maintenance. However,further studies must be addressed including more ES and regions.
