The extensive livestock system of South Patagonia is carried out on large-scale paddocks, with low animal carrying capacity and high environmental fragility. The historical grazing management, since the end of the 19th century, has caused the desertification of the landscape in a large part of the territory. Different institutional efforts have sought to promote better management of rangelands based on adapting the stocking rate of the paddocks. However, the heterogeneity of the landscape within the paddocks still allows the concentration of animals in the most preferred places. In this context, the development of technical recommendations that allow the control of the heterogeneous grazing, requires an updated knowledge about the perception of the producers facing this problem. For this reason, a survey was carried out to 82 extensive livestock producers in Santa Cruz, seeking to characterize the management they perform in the paddocks, the criteria for their design and how they visualize the problem of heterogeneous grazing. A high percentage of producers (~75%) detects the problem, but only 8.3% applies more than 2 technologies to address it. The producers, as a whole, show knowledge of an important variety of technologies. However, different limitations indicated by the interviewees, determine that the technologies are not consolidated as common use practices. The extensive system in South Patagonia continues to be carried out mainly under a scheme of minimal intervention of the landscape, just as in its beginnings. It may be necessary to review the technology transfer system from research and extension institutions. However, the participation of the State is also essential, through the design and implementation of policies that provide suitable instruments to encourage, promote, support and monitor the adoption of technology.
