Given the low production of high quality fodder and environmental issue related to livestock at the regional level, this paper presents the results o research conducted in livestock production systems of tropical high Cauca Department, among the municipalities Silvia, Totoro, and Sotará Puracé. The study aimed to establish a baseline of tree and shrub species with fitness forage utilization in beef production systems for cold climates department dropping a line resulted in 17 families are currently being used by different arrangements livestock. La research systems developed from the recognition and primary data collection with the help of local producers, followed by th systematization and analysis for the identification of those species with highe occurrence and use. Although there were a significant number of species further study is necessary in some of these, since information about thei phenological development and behavior in cattle production systems is still unknown. Thus, the findings constitute a source of information for the design of livestock production systems more efficient in cold climates, while the basis for the formulation of future research proposals related to the field of agroforestry regional ecosystems.
