Along with the Climate Change phenomenon, the presence of Rubus began to decrease. However, it is still possible for some Rubus species to survive the condition. There are at least six Rubus species in Mount Lawu. The six species are Rubus moluccanus, Rubus lineatus, Rubus fraxinifolius, Rubus rosaefolius, Rubus niveus, and Rubus rosifolius. The aims of this research were to initiate stage of Rubus conservation due to increasingly irregular climate change. This research used quadratic transect along the hiking route. The fruits used as samples for the antioxidants, vitamin C, and anthocyanin contents analysis. The results revealed that Rubus moluccanus were found in post 1 and post 3 via Cetho Temple route with abundance value of 0.16 and 3.3. Meanwhile, Rubus rosaefolius and Rubus rosifolius only found in post 1 with abundance value of 0.8 and 0.64. The results also showed that Rubus moluccanus contains 13.78 % antioxidants, 53.17 mg per 100 g vitamin C, and 220 mg per 100 g anthocyanins.
