Broad spectrum of plant species grazed and browsed by cattle in Bolivian subtropical mountain forests

In Southern Bolivia, Department of Tarija, the suptropical Boliviano‐Tucumano mountain forests are used as winter grazing areas for cattle by local livestock keepers.When the dry season starts (April/ May),forage offer declines on the village‐near grassland areas where the cattle usually graze during the rainy season, and the cattle are moved to the mountain forests ( transhumance system) and stay there until the forage offer of the grasslands in the valleys increase again with the first rainfalls and higher temperatures at the beginning of the rainy season (Oct/Nov.) The subtropical forests provide forage even in the critical dry period and are therefore the only possibility for local smallholders to maintain their herds throughout the whole year.Little knowledge exists concerning the diet of the cattle in these mountain ecosystems.This study investigated plant species selection by cattle during the entire period of cattle grazing and browsing in the Boliviano‐Tucumano mountain forests.The results can help to reconcile livestock management and nature reserve conservation.
