Alpacas thrive in Andean ecosystems, efficiently converting natural pasture into products such as fiber and meat, making their breeding a production alternative in Guamote. Intensive grazing and the shift in the spatial distribution of plants due to climate change negatively impact the moorlands. In this context, this study analyzed the influence of floristic composition on the productivity and quality of natural pastures. The methodology included a floristic inventory in a sample of 98 cells in four communities, collecting flora data using the Parker method to measure species composition, density, and cover. In addition, soil fertility and nutritional quality of desirable pastures were assessed through physical and chemical analyses. Principal component and cluster analyses were then applied to correlate the variables. The results showed 26 species, with Poaceae and Asteraceae standing out as dominant and abundant. Tablillas and Pull Quishuar stood out for their productivity and carrying capacity (4.83 t/ha), while Galte Bisñag showed high protein and plant vitality in their pastures. Component 1 stood out for its high production (3.71 t/ha) and carrying capacity in fertile soils; Axis 2 linked Galte Bisñag with high nutritional quality and vegetation cover, while Axis 3 related Asaraty with compacted soils and an intermediate balance. The direct influence between floral species and the productivity of natural pastures leads to the exploration and implementation of measures for sustainable grazing.
