Capacidad de carga de pastos de puna húmeda en un contexto de cambio climático

摘要: ABSTRACT Floristic composition and rangeland condition of the Phynaya Peasant Community (located North Pitumarca district EastNorth Canchis Province, Cusco region) were evaluated to estimate stocking rate under climate change scenario. composition, vegetation cover, plant vigor on 79 step-transects 200 m in six sectors. Preliminary results reveal that there are 60 species, grouped 13 families, where dominant families Poaceae (46.67%), Asteraceas (15%) seudograsses (13.3%), which, 45% palatable for alpacas. Of total grazing areas, alpacas´ areas represent 70.4%, llamas 15.4%, cattle 3.5%, sheep 4.5% y vicunas 6.3%. Actual was 1 alpaca unit per hectare while average estimated fair with supportability 0.78 UAl/ha; thus, rangelands considered degradation process Keywords:  Load capacity, pasture, Phynaya, high Andean
